research methods for interview

Chapter 11. Interviewing

Introduction.

Interviewing people is at the heart of qualitative research. It is not merely a way to collect data but an intrinsically rewarding activity—an interaction between two people that holds the potential for greater understanding and interpersonal development. Unlike many of our daily interactions with others that are fairly shallow and mundane, sitting down with a person for an hour or two and really listening to what they have to say is a profound and deep enterprise, one that can provide not only “data” for you, the interviewer, but also self-understanding and a feeling of being heard for the interviewee. I always approach interviewing with a deep appreciation for the opportunity it gives me to understand how other people experience the world. That said, there is not one kind of interview but many, and some of these are shallower than others. This chapter will provide you with an overview of interview techniques but with a special focus on the in-depth semistructured interview guide approach, which is the approach most widely used in social science research.

An interview can be variously defined as “a conversation with a purpose” ( Lune and Berg 2018 ) and an attempt to understand the world from the point of view of the person being interviewed: “to unfold the meaning of peoples’ experiences, to uncover their lived world prior to scientific explanations” ( Kvale 2007 ). It is a form of active listening in which the interviewer steers the conversation to subjects and topics of interest to their research but also manages to leave enough space for those interviewed to say surprising things. Achieving that balance is a tricky thing, which is why most practitioners believe interviewing is both an art and a science. In my experience as a teacher, there are some students who are “natural” interviewers (often they are introverts), but anyone can learn to conduct interviews, and everyone, even those of us who have been doing this for years, can improve their interviewing skills. This might be a good time to highlight the fact that the interview is a product between interviewer and interviewee and that this product is only as good as the rapport established between the two participants. Active listening is the key to establishing this necessary rapport.

Patton ( 2002 ) makes the argument that we use interviews because there are certain things that are not observable. In particular, “we cannot observe feelings, thoughts, and intentions. We cannot observe behaviors that took place at some previous point in time. We cannot observe situations that preclude the presence of an observer. We cannot observe how people have organized the world and the meanings they attach to what goes on in the world. We have to ask people questions about those things” ( 341 ).

Types of Interviews

There are several distinct types of interviews. Imagine a continuum (figure 11.1). On one side are unstructured conversations—the kind you have with your friends. No one is in control of those conversations, and what you talk about is often random—whatever pops into your head. There is no secret, underlying purpose to your talking—if anything, the purpose is to talk to and engage with each other, and the words you use and the things you talk about are a little beside the point. An unstructured interview is a little like this informal conversation, except that one of the parties to the conversation (you, the researcher) does have an underlying purpose, and that is to understand the other person. You are not friends speaking for no purpose, but it might feel just as unstructured to the “interviewee” in this scenario. That is one side of the continuum. On the other side are fully structured and standardized survey-type questions asked face-to-face. Here it is very clear who is asking the questions and who is answering them. This doesn’t feel like a conversation at all! A lot of people new to interviewing have this ( erroneously !) in mind when they think about interviews as data collection. Somewhere in the middle of these two extreme cases is the “ semistructured” interview , in which the researcher uses an “interview guide” to gently move the conversation to certain topics and issues. This is the primary form of interviewing for qualitative social scientists and will be what I refer to as interviewing for the rest of this chapter, unless otherwise specified.

Informal (unstructured conversations). This is the most “open-ended” approach to interviewing. It is particularly useful in conjunction with observational methods (see chapters 13 and 14). There are no predetermined questions. Each interview will be different. Imagine you are researching the Oregon Country Fair, an annual event in Veneta, Oregon, that includes live music, artisan craft booths, face painting, and a lot of people walking through forest paths. It’s unlikely that you will be able to get a person to sit down with you and talk intensely about a set of questions for an hour and a half. But you might be able to sidle up to several people and engage with them about their experiences at the fair. You might have a general interest in what attracts people to these events, so you could start a conversation by asking strangers why they are here or why they come back every year. That’s it. Then you have a conversation that may lead you anywhere. Maybe one person tells a long story about how their parents brought them here when they were a kid. A second person talks about how this is better than Burning Man. A third person shares their favorite traveling band. And yet another enthuses about the public library in the woods. During your conversations, you also talk about a lot of other things—the weather, the utilikilts for sale, the fact that a favorite food booth has disappeared. It’s all good. You may not be able to record these conversations. Instead, you might jot down notes on the spot and then, when you have the time, write down as much as you can remember about the conversations in long fieldnotes. Later, you will have to sit down with these fieldnotes and try to make sense of all the information (see chapters 18 and 19).

Interview guide ( semistructured interview ). This is the primary type employed by social science qualitative researchers. The researcher creates an “interview guide” in advance, which she uses in every interview. In theory, every person interviewed is asked the same questions. In practice, every person interviewed is asked mostly the same topics but not always the same questions, as the whole point of a “guide” is that it guides the direction of the conversation but does not command it. The guide is typically between five and ten questions or question areas, sometimes with suggested follow-ups or prompts . For example, one question might be “What was it like growing up in Eastern Oregon?” with prompts such as “Did you live in a rural area? What kind of high school did you attend?” to help the conversation develop. These interviews generally take place in a quiet place (not a busy walkway during a festival) and are recorded. The recordings are transcribed, and those transcriptions then become the “data” that is analyzed (see chapters 18 and 19). The conventional length of one of these types of interviews is between one hour and two hours, optimally ninety minutes. Less than one hour doesn’t allow for much development of questions and thoughts, and two hours (or more) is a lot of time to ask someone to sit still and answer questions. If you have a lot of ground to cover, and the person is willing, I highly recommend two separate interview sessions, with the second session being slightly shorter than the first (e.g., ninety minutes the first day, sixty minutes the second). There are lots of good reasons for this, but the most compelling one is that this allows you to listen to the first day’s recording and catch anything interesting you might have missed in the moment and so develop follow-up questions that can probe further. This also allows the person being interviewed to have some time to think about the issues raised in the interview and go a little deeper with their answers.

Standardized questionnaire with open responses ( structured interview ). This is the type of interview a lot of people have in mind when they hear “interview”: a researcher comes to your door with a clipboard and proceeds to ask you a series of questions. These questions are all the same whoever answers the door; they are “standardized.” Both the wording and the exact order are important, as people’s responses may vary depending on how and when a question is asked. These are qualitative only in that the questions allow for “open-ended responses”: people can say whatever they want rather than select from a predetermined menu of responses. For example, a survey I collaborated on included this open-ended response question: “How does class affect one’s career success in sociology?” Some of the answers were simply one word long (e.g., “debt”), and others were long statements with stories and personal anecdotes. It is possible to be surprised by the responses. Although it’s a stretch to call this kind of questioning a conversation, it does allow the person answering the question some degree of freedom in how they answer.

Survey questionnaire with closed responses (not an interview!). Standardized survey questions with specific answer options (e.g., closed responses) are not really interviews at all, and they do not generate qualitative data. For example, if we included five options for the question “How does class affect one’s career success in sociology?”—(1) debt, (2) social networks, (3) alienation, (4) family doesn’t understand, (5) type of grad program—we leave no room for surprises at all. Instead, we would most likely look at patterns around these responses, thinking quantitatively rather than qualitatively (e.g., using regression analysis techniques, we might find that working-class sociologists were twice as likely to bring up alienation). It can sometimes be confusing for new students because the very same survey can include both closed-ended and open-ended questions. The key is to think about how these will be analyzed and to what level surprises are possible. If your plan is to turn all responses into a number and make predictions about correlations and relationships, you are no longer conducting qualitative research. This is true even if you are conducting this survey face-to-face with a real live human. Closed-response questions are not conversations of any kind, purposeful or not.

In summary, the semistructured interview guide approach is the predominant form of interviewing for social science qualitative researchers because it allows a high degree of freedom of responses from those interviewed (thus allowing for novel discoveries) while still maintaining some connection to a research question area or topic of interest. The rest of the chapter assumes the employment of this form.

Creating an Interview Guide

Your interview guide is the instrument used to bridge your research question(s) and what the people you are interviewing want to tell you. Unlike a standardized questionnaire, the questions actually asked do not need to be exactly what you have written down in your guide. The guide is meant to create space for those you are interviewing to talk about the phenomenon of interest, but sometimes you are not even sure what that phenomenon is until you start asking questions. A priority in creating an interview guide is to ensure it offers space. One of the worst mistakes is to create questions that are so specific that the person answering them will not stray. Relatedly, questions that sound “academic” will shut down a lot of respondents. A good interview guide invites respondents to talk about what is important to them, not feel like they are performing or being evaluated by you.

Good interview questions should not sound like your “research question” at all. For example, let’s say your research question is “How do patriarchal assumptions influence men’s understanding of climate change and responses to climate change?” It would be worse than unhelpful to ask a respondent, “How do your assumptions about the role of men affect your understanding of climate change?” You need to unpack this into manageable nuggets that pull your respondent into the area of interest without leading him anywhere. You could start by asking him what he thinks about climate change in general. Or, even better, whether he has any concerns about heatwaves or increased tornadoes or polar icecaps melting. Once he starts talking about that, you can ask follow-up questions that bring in issues around gendered roles, perhaps asking if he is married (to a woman) and whether his wife shares his thoughts and, if not, how they negotiate that difference. The fact is, you won’t really know the right questions to ask until he starts talking.

There are several distinct types of questions that can be used in your interview guide, either as main questions or as follow-up probes. If you remember that the point is to leave space for the respondent, you will craft a much more effective interview guide! You will also want to think about the place of time in both the questions themselves (past, present, future orientations) and the sequencing of the questions.

Researcher Note

Suggestion : As you read the next three sections (types of questions, temporality, question sequence), have in mind a particular research question, and try to draft questions and sequence them in a way that opens space for a discussion that helps you answer your research question.

Type of Questions

Experience and behavior questions ask about what a respondent does regularly (their behavior) or has done (their experience). These are relatively easy questions for people to answer because they appear more “factual” and less subjective. This makes them good opening questions. For the study on climate change above, you might ask, “Have you ever experienced an unusual weather event? What happened?” Or “You said you work outside? What is a typical summer workday like for you? How do you protect yourself from the heat?”

Opinion and values questions , in contrast, ask questions that get inside the minds of those you are interviewing. “Do you think climate change is real? Who or what is responsible for it?” are two such questions. Note that you don’t have to literally ask, “What is your opinion of X?” but you can find a way to ask the specific question relevant to the conversation you are having. These questions are a bit trickier to ask because the answers you get may depend in part on how your respondent perceives you and whether they want to please you or not. We’ve talked a fair amount about being reflective. Here is another place where this comes into play. You need to be aware of the effect your presence might have on the answers you are receiving and adjust accordingly. If you are a woman who is perceived as liberal asking a man who identifies as conservative about climate change, there is a lot of subtext that can be going on in the interview. There is no one right way to resolve this, but you must at least be aware of it.

Feeling questions are questions that ask respondents to draw on their emotional responses. It’s pretty common for academic researchers to forget that we have bodies and emotions, but people’s understandings of the world often operate at this affective level, sometimes unconsciously or barely consciously. It is a good idea to include questions that leave space for respondents to remember, imagine, or relive emotional responses to particular phenomena. “What was it like when you heard your cousin’s house burned down in that wildfire?” doesn’t explicitly use any emotion words, but it allows your respondent to remember what was probably a pretty emotional day. And if they respond emotionally neutral, that is pretty interesting data too. Note that asking someone “How do you feel about X” is not always going to evoke an emotional response, as they might simply turn around and respond with “I think that…” It is better to craft a question that actually pushes the respondent into the affective category. This might be a specific follow-up to an experience and behavior question —for example, “You just told me about your daily routine during the summer heat. Do you worry it is going to get worse?” or “Have you ever been afraid it will be too hot to get your work accomplished?”

Knowledge questions ask respondents what they actually know about something factual. We have to be careful when we ask these types of questions so that respondents do not feel like we are evaluating them (which would shut them down), but, for example, it is helpful to know when you are having a conversation about climate change that your respondent does in fact know that unusual weather events have increased and that these have been attributed to climate change! Asking these questions can set the stage for deeper questions and can ensure that the conversation makes the same kind of sense to both participants. For example, a conversation about political polarization can be put back on track once you realize that the respondent doesn’t really have a clear understanding that there are two parties in the US. Instead of asking a series of questions about Republicans and Democrats, you might shift your questions to talk more generally about political disagreements (e.g., “people against abortion”). And sometimes what you do want to know is the level of knowledge about a particular program or event (e.g., “Are you aware you can discharge your student loans through the Public Service Loan Forgiveness program?”).

Sensory questions call on all senses of the respondent to capture deeper responses. These are particularly helpful in sparking memory. “Think back to your childhood in Eastern Oregon. Describe the smells, the sounds…” Or you could use these questions to help a person access the full experience of a setting they customarily inhabit: “When you walk through the doors to your office building, what do you see? Hear? Smell?” As with feeling questions , these questions often supplement experience and behavior questions . They are another way of allowing your respondent to report fully and deeply rather than remain on the surface.

Creative questions employ illustrative examples, suggested scenarios, or simulations to get respondents to think more deeply about an issue, topic, or experience. There are many options here. In The Trouble with Passion , Erin Cech ( 2021 ) provides a scenario in which “Joe” is trying to decide whether to stay at his decent but boring computer job or follow his passion by opening a restaurant. She asks respondents, “What should Joe do?” Their answers illuminate the attraction of “passion” in job selection. In my own work, I have used a news story about an upwardly mobile young man who no longer has time to see his mother and sisters to probe respondents’ feelings about the costs of social mobility. Jessi Streib and Betsy Leondar-Wright have used single-page cartoon “scenes” to elicit evaluations of potential racial discrimination, sexual harassment, and classism. Barbara Sutton ( 2010 ) has employed lists of words (“strong,” “mother,” “victim”) on notecards she fans out and asks her female respondents to select and discuss.

Background/Demographic Questions

You most definitely will want to know more about the person you are interviewing in terms of conventional demographic information, such as age, race, gender identity, occupation, and educational attainment. These are not questions that normally open up inquiry. [1] For this reason, my practice has been to include a separate “demographic questionnaire” sheet that I ask each respondent to fill out at the conclusion of the interview. Only include those aspects that are relevant to your study. For example, if you are not exploring religion or religious affiliation, do not include questions about a person’s religion on the demographic sheet. See the example provided at the end of this chapter.

Temporality

Any type of question can have a past, present, or future orientation. For example, if you are asking a behavior question about workplace routine, you might ask the respondent to talk about past work, present work, and ideal (future) work. Similarly, if you want to understand how people cope with natural disasters, you might ask your respondent how they felt then during the wildfire and now in retrospect and whether and to what extent they have concerns for future wildfire disasters. It’s a relatively simple suggestion—don’t forget to ask about past, present, and future—but it can have a big impact on the quality of the responses you receive.

Question Sequence

Having a list of good questions or good question areas is not enough to make a good interview guide. You will want to pay attention to the order in which you ask your questions. Even though any one respondent can derail this order (perhaps by jumping to answer a question you haven’t yet asked), a good advance plan is always helpful. When thinking about sequence, remember that your goal is to get your respondent to open up to you and to say things that might surprise you. To establish rapport, it is best to start with nonthreatening questions. Asking about the present is often the safest place to begin, followed by the past (they have to know you a little bit to get there), and lastly, the future (talking about hopes and fears requires the most rapport). To allow for surprises, it is best to move from very general questions to more particular questions only later in the interview. This ensures that respondents have the freedom to bring up the topics that are relevant to them rather than feel like they are constrained to answer you narrowly. For example, refrain from asking about particular emotions until these have come up previously—don’t lead with them. Often, your more particular questions will emerge only during the course of the interview, tailored to what is emerging in conversation.

Once you have a set of questions, read through them aloud and imagine you are being asked the same questions. Does the set of questions have a natural flow? Would you be willing to answer the very first question to a total stranger? Does your sequence establish facts and experiences before moving on to opinions and values? Did you include prefatory statements, where necessary; transitions; and other announcements? These can be as simple as “Hey, we talked a lot about your experiences as a barista while in college.… Now I am turning to something completely different: how you managed friendships in college.” That is an abrupt transition, but it has been softened by your acknowledgment of that.

Probes and Flexibility

Once you have the interview guide, you will also want to leave room for probes and follow-up questions. As in the sample probe included here, you can write out the obvious probes and follow-up questions in advance. You might not need them, as your respondent might anticipate them and include full responses to the original question. Or you might need to tailor them to how your respondent answered the question. Some common probes and follow-up questions include asking for more details (When did that happen? Who else was there?), asking for elaboration (Could you say more about that?), asking for clarification (Does that mean what I think it means or something else? I understand what you mean, but someone else reading the transcript might not), and asking for contrast or comparison (How did this experience compare with last year’s event?). “Probing is a skill that comes from knowing what to look for in the interview, listening carefully to what is being said and what is not said, and being sensitive to the feedback needs of the person being interviewed” ( Patton 2002:374 ). It takes work! And energy. I and many other interviewers I know report feeling emotionally and even physically drained after conducting an interview. You are tasked with active listening and rearranging your interview guide as needed on the fly. If you only ask the questions written down in your interview guide with no deviations, you are doing it wrong. [2]

The Final Question

Every interview guide should include a very open-ended final question that allows for the respondent to say whatever it is they have been dying to tell you but you’ve forgotten to ask. About half the time they are tired too and will tell you they have nothing else to say. But incredibly, some of the most honest and complete responses take place here, at the end of a long interview. You have to realize that the person being interviewed is often discovering things about themselves as they talk to you and that this process of discovery can lead to new insights for them. Making space at the end is therefore crucial. Be sure you convey that you actually do want them to tell you more, that the offer of “anything else?” is not read as an empty convention where the polite response is no. Here is where you can pull from that active listening and tailor the final question to the particular person. For example, “I’ve asked you a lot of questions about what it was like to live through that wildfire. I’m wondering if there is anything I’ve forgotten to ask, especially because I haven’t had that experience myself” is a much more inviting final question than “Great. Anything you want to add?” It’s also helpful to convey to the person that you have the time to listen to their full answer, even if the allotted time is at the end. After all, there are no more questions to ask, so the respondent knows exactly how much time is left. Do them the courtesy of listening to them!

Conducting the Interview

Once you have your interview guide, you are on your way to conducting your first interview. I always practice my interview guide with a friend or family member. I do this even when the questions don’t make perfect sense for them, as it still helps me realize which questions make no sense, are poorly worded (too academic), or don’t follow sequentially. I also practice the routine I will use for interviewing, which goes something like this:

• Introduce myself and reintroduce the study
• Provide consent form and ask them to sign and retain/return copy
• Ask if they have any questions about the study before we begin
• Ask if I can begin recording
• Ask questions (from interview guide)
• Turn off the recording device
• Ask if they are willing to fill out my demographic questionnaire
• Collect questionnaire and, without looking at the answers, place in same folder as signed consent form
• Thank them and depart

A note on remote interviewing: Interviews have traditionally been conducted face-to-face in a private or quiet public setting. You don’t want a lot of background noise, as this will make transcriptions difficult. During the recent global pandemic, many interviewers, myself included, learned the benefits of interviewing remotely. Although face-to-face is still preferable for many reasons, Zoom interviewing is not a bad alternative, and it does allow more interviews across great distances. Zoom also includes automatic transcription, which significantly cuts down on the time it normally takes to convert our conversations into “data” to be analyzed. These automatic transcriptions are not perfect, however, and you will still need to listen to the recording and clarify and clean up the transcription. Nor do automatic transcriptions include notations of body language or change of tone, which you may want to include. When interviewing remotely, you will want to collect the consent form before you meet: ask them to read, sign, and return it as an email attachment. I think it is better to ask for the demographic questionnaire after the interview, but because some respondents may never return it then, it is probably best to ask for this at the same time as the consent form, in advance of the interview.

What should you bring to the interview? I would recommend bringing two copies of the consent form (one for you and one for the respondent), a demographic questionnaire, a manila folder in which to place the signed consent form and filled-out demographic questionnaire, a printed copy of your interview guide (I print with three-inch right margins so I can jot down notes on the page next to relevant questions), a pen, a recording device, and water.

After the interview, you will want to secure the signed consent form in a locked filing cabinet (if in print) or a password-protected folder on your computer. Using Excel or a similar program that allows tables/spreadsheets, create an identifying number for your interview that links to the consent form without using the name of your respondent. For example, let’s say that I conduct interviews with US politicians, and the first person I meet with is George W. Bush. I will assign the transcription the number “INT#001” and add it to the signed consent form. [3] The signed consent form goes into a locked filing cabinet, and I never use the name “George W. Bush” again. I take the information from the demographic sheet, open my Excel spreadsheet, and add the relevant information in separate columns for the row INT#001: White, male, Republican. When I interview Bill Clinton as my second interview, I include a second row: INT#002: White, male, Democrat. And so on. The only link to the actual name of the respondent and this information is the fact that the consent form (unavailable to anyone but me) has stamped on it the interview number.

Many students get very nervous before their first interview. Actually, many of us are always nervous before the interview! But do not worry—this is normal, and it does pass. Chances are, you will be pleasantly surprised at how comfortable it begins to feel. These “purposeful conversations” are often a delight for both participants. This is not to say that sometimes things go wrong. I often have my students practice several “bad scenarios” (e.g., a respondent that you cannot get to open up; a respondent who is too talkative and dominates the conversation, steering it away from the topics you are interested in; emotions that completely take over; or shocking disclosures you are ill-prepared to handle), but most of the time, things go quite well. Be prepared for the unexpected, but know that the reason interviews are so popular as a technique of data collection is that they are usually richly rewarding for both participants.

One thing that I stress to my methods students and remind myself about is that interviews are still conversations between people. If there’s something you might feel uncomfortable asking someone about in a “normal” conversation, you will likely also feel a bit of discomfort asking it in an interview. Maybe more importantly, your respondent may feel uncomfortable. Social research—especially about inequality—can be uncomfortable. And it’s easy to slip into an abstract, intellectualized, or removed perspective as an interviewer. This is one reason trying out interview questions is important. Another is that sometimes the question sounds good in your head but doesn’t work as well out loud in practice. I learned this the hard way when a respondent asked me how I would answer the question I had just posed, and I realized that not only did I not really know how I would answer it, but I also wasn’t quite as sure I knew what I was asking as I had thought.

How Many Interviews?

Your research design has included a targeted number of interviews and a recruitment plan (see chapter 5). Follow your plan, but remember that “ saturation ” is your goal. You interview as many people as you can until you reach a point at which you are no longer surprised by what they tell you. This means not that no one after your first twenty interviews will have surprising, interesting stories to tell you but rather that the picture you are forming about the phenomenon of interest to you from a research perspective has come into focus, and none of the interviews are substantially refocusing that picture. That is when you should stop collecting interviews. Note that to know when you have reached this, you will need to read your transcripts as you go. More about this in chapters 18 and 19.

Your Final Product: The Ideal Interview Transcript

A good interview transcript will demonstrate a subtly controlled conversation by the skillful interviewer. In general, you want to see replies that are about one paragraph long, not short sentences and not running on for several pages. Although it is sometimes necessary to follow respondents down tangents, it is also often necessary to pull them back to the questions that form the basis of your research study. This is not really a free conversation, although it may feel like that to the person you are interviewing.

Final Tips from an Interview Master

Annette Lareau is arguably one of the masters of the trade. In Listening to People , she provides several guidelines for good interviews and then offers a detailed example of an interview gone wrong and how it could be addressed (please see the “Further Readings” at the end of this chapter). Here is an abbreviated version of her set of guidelines: (1) interview respondents who are experts on the subjects of most interest to you (as a corollary, don’t ask people about things they don’t know); (2) listen carefully and talk as little as possible; (3) keep in mind what you want to know and why you want to know it; (4) be a proactive interviewer (subtly guide the conversation); (5) assure respondents that there aren’t any right or wrong answers; (6) use the respondent’s own words to probe further (this both allows you to accurately identify what you heard and pushes the respondent to explain further); (7) reuse effective probes (don’t reinvent the wheel as you go—if repeating the words back works, do it again and again); (8) focus on learning the subjective meanings that events or experiences have for a respondent; (9) don’t be afraid to ask a question that draws on your own knowledge (unlike trial lawyers who are trained never to ask a question for which they don’t already know the answer, sometimes it’s worth it to ask risky questions based on your hypotheses or just plain hunches); (10) keep thinking while you are listening (so difficult…and important); (11) return to a theme raised by a respondent if you want further information; (12) be mindful of power inequalities (and never ever coerce a respondent to continue the interview if they want out); (13) take control with overly talkative respondents; (14) expect overly succinct responses, and develop strategies for probing further; (15) balance digging deep and moving on; (16) develop a plan to deflect questions (e.g., let them know you are happy to answer any questions at the end of the interview, but you don’t want to take time away from them now); and at the end, (17) check to see whether you have asked all your questions. You don’t always have to ask everyone the same set of questions, but if there is a big area you have forgotten to cover, now is the time to recover ( Lareau 2021:93–103 ).

A document listing key questions and question areas for use during an interview.  It is used most often for semi-structured interviews.  A good interview guide may have no more than ten primary questions for two hours of interviewing, but these ten questions will be supplemented by probes and relevant follow-ups throughout the interview.  Most IRBs require the inclusion of the interview guide in applications for review.  See also interview and  semi-structured interview .

A data-collection method that relies on casual, conversational, and informal interviewing.  Despite its apparent conversational nature, the researcher usually has a set of particular questions or question areas in mind but allows the interview to unfold spontaneously.  This is a common data-collection technique among ethnographers.  Compare to the semi-structured or in-depth interview .

A form of interview that follows a standard guide of questions asked, although the order of the questions may change to match the particular needs of each individual interview subject, and probing “follow-up” questions are often added during the course of the interview.  The semi-structured interview is the primary form of interviewing used by qualitative researchers in the social sciences.  It is sometimes referred to as an “in-depth” interview.  See also interview and  interview guide .

The cluster of data-collection tools and techniques that involve observing interactions between people, the behaviors, and practices of individuals (sometimes in contrast to what they say about how they act and behave), and cultures in context.  Observational methods are the key tools employed by ethnographers and Grounded Theory .

Follow-up questions used in a semi-structured interview  to elicit further elaboration.  Suggested prompts can be included in the interview guide  to be used/deployed depending on how the initial question was answered or if the topic of the prompt does not emerge spontaneously.

A form of interview that follows a strict set of questions, asked in a particular order, for all interview subjects.  The questions are also the kind that elicits short answers, and the data is more “informative” than probing.  This is often used in mixed-methods studies, accompanying a survey instrument.  Because there is no room for nuance or the exploration of meaning in structured interviews, qualitative researchers tend to employ semi-structured interviews instead.  See also interview.

Interviews involve a conversation with a purpose, but have some distinct features compared to ordinary conversation, such as being scheduled in advance, having an asymmetry in outcome goals between interviewer and interviewee, and often following a question-answer format.

Interviews are different from questionnaires as they involve social interaction. Unlike questionnaire methods, researchers need training in interviewing (which costs money).

How Do Interviews Work?

Researchers can ask different types of questions, generating different types of data . For example, closed questions provide people with a fixed set of responses, whereas open questions allow people to express what they think in their own words.

The researcher will often record interviews, and the data will be written up as a transcript (a written account of interview questions and answers) which can be analyzed later.

It should be noted that interviews may not be the best method for researching sensitive topics (e.g., truancy in schools, discrimination, etc.) as people may feel more comfortable completing a questionnaire in private.

There are different types of interviews, with a key distinction being the extent of structure. Semi-structured is most common in psychology research. Unstructured interviews have a free-flowing style, while structured interviews involve preset questions asked in a particular order.

Structured Interview

A structured interview is a quantitative research method where the interviewer a set of prepared closed-ended questions in the form of an interview schedule, which he/she reads out exactly as worded.

Interviews schedules have a standardized format, meaning the same questions are asked to each interviewee in the same order (see Fig. 1).

   Figure 1. An example of an interview schedule

The interviewer will not deviate from the interview schedule (except to clarify the meaning of the question) or probe beyond the answers received.  Replies are recorded on a questionnaire, and the order and wording of questions, and sometimes the range of alternative answers, is preset by the researcher.

A structured interview is also known as a formal interview (like a job interview).

• Structured interviews are easy to replicate as a fixed set of closed questions are used, which are easy to quantify – this means it is easy to test for reliability .
• Structured interviews are fairly quick to conduct which means that many interviews can take place within a short amount of time. This means a large sample can be obtained, resulting in the findings being representative and having the ability to be generalized to a large population.

Limitations

• Structured interviews are not flexible. This means new questions cannot be asked impromptu (i.e., during the interview), as an interview schedule must be followed.
• The answers from structured interviews lack detail as only closed questions are asked, which generates quantitative data . This means a researcher won’t know why a person behaves a certain way.

Unstructured Interview

Unstructured interviews do not use any set questions, instead, the interviewer asks open-ended questions based on a specific research topic, and will try to let the interview flow like a natural conversation. The interviewer modifies his or her questions to suit the candidate’s specific experiences.

Unstructured interviews are sometimes referred to as ‘discovery interviews’ and are more like a ‘guided conservation’ than a strictly structured interview. They are sometimes called informal interviews.

Unstructured interviews are most useful in qualitative research to analyze attitudes and values. Though they rarely provide a valid basis for generalization, their main advantage is that they enable the researcher to probe social actors’ subjective points of view.

Interviewer Self-Disclosure

Interviewer self-disclosure involves the interviewer revealing personal information or opinions during the research interview. This may increase rapport but risks changing dynamics away from a focus on facilitating the interviewee’s account.

In unstructured interviews, the informal conversational style may deliberately include elements of interviewer self-disclosure, mirroring ordinary conversation dynamics.

Interviewer self-disclosure risks changing the dynamics away from facilitation of interviewee accounts. It should not be ruled out entirely but requires skillful handling informed by reflection.

• An informal interviewing style with some interviewer self-disclosure may increase rapport and participant openness. However, it also increases the chance of the participant converging opinions with the interviewer.
• Complete interviewer neutrality is unlikely. However, excessive informality and self-disclosure risk the interview becoming more of an ordinary conversation and producing consensus accounts.
• Overly personal disclosures could also be seen as irrelevant and intrusive by participants. They may invite increased intimacy on uncomfortable topics.
• The safest approach seems to be to avoid interviewer self-disclosures in most cases. Where an informal style is used, disclosures require careful judgment and substantial interviewing experience.
• If asked for personal opinions during an interview, the interviewer could highlight the defined roles and defer that discussion until after the interview.
• Unstructured interviews are more flexible as questions can be adapted and changed depending on the respondents’ answers. The interview can deviate from the interview schedule.
• Unstructured interviews generate qualitative data through the use of open questions. This allows the respondent to talk in some depth, choosing their own words. This helps the researcher develop a real sense of a person’s understanding of a situation.
• They also have increased validity because it gives the interviewer the opportunity to probe for a deeper understanding, ask for clarification & allow the interviewee to steer the direction of the interview, etc. Interviewers have the chance to clarify any questions of participants during the interview.
• It can be time-consuming to conduct an unstructured interview and analyze the qualitative data (using methods such as thematic analysis).
• Employing and training interviewers is expensive and not as cheap as collecting data via questionnaires . For example, certain skills may be needed by the interviewer. These include the ability to establish rapport and knowing when to probe.
• Interviews inevitably co-construct data through researchers’ agenda-setting and question-framing. Techniques like open questions provide only limited remedies.

Focus Group Interview

Focus group interview is a qualitative approach where a group of respondents are interviewed together, used to gain an in‐depth understanding of social issues.

This type of interview is often referred to as a focus group because the job of the interviewer ( or moderator ) is to bring the group to focus on the issue at hand. Initially, the goal was to reach a consensus among the group, but with the development of techniques for analyzing group qualitative data, there is less emphasis on consensus building.

The method aims to obtain data from a purposely selected group of individuals rather than from a statistically representative sample of a broader population.

The role of the interview moderator is to make sure the group interacts with each other and do not drift off-topic. Ideally, the moderator will be similar to the participants in terms of appearance, have adequate knowledge of the topic being discussed, and exercise mild unobtrusive control over dominant talkers and shy participants.

A researcher must be highly skilled to conduct a focus group interview. For example, the moderator may need certain skills, including the ability to establish rapport and know when to probe.

• Group interviews generate qualitative narrative data through the use of open questions. This allows the respondents to talk in some depth, choosing their own words. This helps the researcher develop a real sense of a person’s understanding of a situation. Qualitative data also includes observational data, such as body language and facial expressions.
• Group responses are helpful when you want to elicit perspectives on a collective experience, encourage diversity of thought, reduce researcher bias, and gather a wider range of contextualized views.
• They also have increased validity because some participants may feel more comfortable being with others as they are used to talking in groups in real life (i.e., it’s more natural).
• When participants have common experiences, focus groups allow them to build on each other’s comments to provide richer contextual data representing a wider range of views than individual interviews.
• Focus groups are a type of group interview method used in market research and consumer psychology that are cost – effective for gathering the views of consumers .
• The researcher must ensure that they keep all the interviewees” details confidential and respect their privacy. This is difficult when using a group interview. For example, the researcher cannot guarantee that the other people in the group will keep information private.
• Group interviews are less reliable as they use open questions and may deviate from the interview schedule, making them difficult to repeat.
• It is important to note that there are some potential pitfalls of focus groups, such as conformity, social desirability, and oppositional behavior, that can reduce the usefulness of the data collected.

For example, group interviews may sometimes lack validity as participants may lie to impress the other group members. They may conform to peer pressure and give false answers.

To avoid these pitfalls, the interviewer needs to have a good understanding of how people function in groups as well as how to lead the group in a productive discussion.

Semi-Structured Interview

Semi-structured interviews lie between structured and unstructured interviews. The interviewer prepares a set of same questions to be answered by all interviewees. Additional questions might be asked during the interview to clarify or expand certain issues.

In semi-structured interviews, the interviewer has more freedom to digress and probe beyond the answers. The interview guide contains a list of questions and topics that need to be covered during the conversation, usually in a particular order.

Semi-structured interviews are most useful to address the ‘what’, ‘how’, and ‘why’ research questions. Both qualitative and quantitative analyses can be performed on data collected during semi-structured interviews.

• Semi-structured interviews allow respondents to answer more on their terms in an informal setting yet provide uniform information making them ideal for qualitative analysis.
• The flexible nature of semi-structured interviews allows ideas to be introduced and explored during the interview based on the respondents’ answers.
• Semi-structured interviews can provide reliable and comparable qualitative data. Allows the interviewer to probe answers, where the interviewee is asked to clarify or expand on the answers provided.
• The data generated remain fundamentally shaped by the interview context itself. Analysis rarely acknowledges this endemic co-construction.
• They are more time-consuming (to conduct, transcribe, and analyze) than structured interviews.
• The quality of findings is more dependent on the individual skills of the interviewer than in structured interviews. Skill is required to probe effectively while avoiding biasing responses.

The Interviewer Effect

Face-to-face interviews raise methodological problems. These stem from the fact that interviewers are themselves role players, and their perceived status may influence the replies of the respondents.

Because an interview is a social interaction, the interviewer’s appearance or behavior may influence the respondent’s answers. This is a problem as it can bias the results of the study and make them invalid.

For example, the gender, ethnicity, body language, age, and social status of the interview can all create an interviewer effect. If there is a perceived status disparity between the interviewer and the interviewee, the results of interviews have to be interpreted with care. This is pertinent for sensitive topics such as health.

For example, if a researcher was investigating sexism amongst males, would a female interview be preferable to a male? It is possible that if a female interviewer was used, male participants might lie (i.e., pretend they are not sexist) to impress the interviewer, thus creating an interviewer effect.

Flooding interviews with researcher’s agenda

The interactional nature of interviews means the researcher fundamentally shapes the discourse, rather than just neutrally collecting it. This shapes what is talked about and how participants can respond.

• The interviewer’s assumptions, interests, and categories don’t just shape the specific interview questions asked. They also shape the framing, task instructions, recruitment, and ongoing responses/prompts.
• This flooding of the interview interaction with the researcher’s agenda makes it very difficult to separate out what comes from the participant vs. what is aligned with the interviewer’s concerns.
• So the participant’s talk ends up being fundamentally shaped by the interviewer rather than being a more natural reflection of the participant’s own orientations or practices.
• This effect is hard to avoid because interviews inherently involve the researcher setting an agenda. But it does mean the talk extracted may say more about the interview process than the reality it is supposed to reflect.

Interview Design

First, you must choose whether to use a structured or non-structured interview.

Characteristics of Interviewers

Next, you must consider who will be the interviewer, and this will depend on what type of person is being interviewed. There are several variables to consider:

• Gender and age : This can greatly affect respondents’ answers, particularly on personal issues.
• Personal characteristics : Some people are easier to get on with than others. Also, the interviewer’s accent and appearance (e.g., clothing) can affect the rapport between the interviewer and interviewee.
• Language : The interviewer’s language should be appropriate to the vocabulary of the group of people being studied. For example, the researcher must change the questions’ language to match the respondents’ social background” age / educational level / social class/ethnicity, etc.
• Ethnicity : People may have difficulty interviewing people from different ethnic groups.
• Interviewer expertise should match research sensitivity – inexperienced students should avoid interviewing highly vulnerable groups.

Interview Location

The location of a research interview can influence the way in which the interviewer and interviewee relate and may exaggerate a power dynamic in one direction or another. It is usual to offer interviewees a choice of location as part of facilitating their comfort and encouraging participation.

However, the safety of the interviewer is an overriding consideration and, as mentioned, a minimal requirement should be that a responsible person knows where the interviewer has gone and when they are due back.

Remote Interviews

The COVID-19 pandemic necessitated remote interviewing for research continuity. However online interview platforms provide increased flexibility even under normal conditions.

They enable access to participant groups across geographical distances without travel costs or arrangements. Online interviews can be efficiently scheduled to align with researcher and interviewee availability.

There are practical considerations in setting up remote interviews. Interviewees require access to internet and an online platform such as Zoom, Microsoft Teams or Skype through which to connect.

Certain modifications help build initial rapport in the remote format. Allowing time at the start of the interview for casual conversation while testing audio/video quality helps participants settle in. Minor delays can disrupt turn-taking flow, so alerting participants to speak slightly slower than usual minimizes accidental interruptions.

Keeping remote interviews under an hour avoids fatigue for stare at a screen. Seeking advanced ethical clearance for verbal consent at the interview start saves participant time. Adapting to the remote context shows care for interviewees and aids rich discussion.

However, it remains important to critically reflect on how removing in-person dynamics may shape the co-created data. Perhaps some nuances of trust and disclosure differ over video.

Vulnerable Groups

The interviewer must ensure that they take special care when interviewing vulnerable groups, such as children. For example, children have a limited attention span, so lengthy interviews should be avoided.

Developing an Interview Schedule

An interview schedule is a list of pre-planned, structured questions that have been prepared, to serve as a guide for interviewers, researchers and investigators in collecting information or data about a specific topic or issue.

• List the key themes or topics that must be covered to address your research questions. This will form the basic content.
• Organize the content logically, such as chronologically following the interviewee’s experiences. Place more sensitive topics later in the interview.
• Develop the list of content into actual questions and prompts. Carefully word each question – keep them open-ended, non-leading, and focused on examples.
• Add prompts to remind you to cover areas of interest.
• Pilot test the interview schedule to check it generates useful data and revise as needed.
• Be prepared to refine the schedule throughout data collection as you learn which questions work better.
• Practice skills like asking follow-up questions to get depth and detail. Stay flexible to depart from the schedule when needed.
• Keep questions brief and clear. Avoid multi-part questions that risk confusing interviewees.
• Listen actively during interviews to determine which pre-planned questions can be skipped based on information the participant has already provided.

The key is balancing preparation with the flexibility to adapt questions based on each interview interaction. With practice, you’ll gain skills to conduct productive interviews that obtain rich qualitative data.

The Power of Silence

Strategic use of silence is a key technique to generate interviewee-led data, but it requires judgment about appropriate timing and duration to maintain mutual understanding.

• Unlike ordinary conversation, the interviewer aims to facilitate the interviewee’s contribution without interrupting. This often means resisting the urge to speak at the end of the interviewee’s turn construction units (TCUs).
• Leaving a silence after a TCU encourages the interviewee to provide more material without being led by the interviewer. However, this simple technique requires confidence, as silence can feel socially awkward.
• Allowing longer silences (e.g. 24 seconds) later in interviews can work well, but early on even short silences may disrupt rapport if they cause misalignment between speakers.
• Silence also allows interviewees time to think before answering. Rushing to re-ask or amend questions can limit responses.
• Blunt backchannels like “mm hm” also avoid interrupting flow. Interruptions, especially to finish an interviewee’s turn, are problematic as they make the ownership of perspectives unclear.
• If interviewers incorrectly complete turns, an upside is it can produce extended interviewee narratives correcting the record. However, silence would have been better to let interviewees shape their own accounts.

Interviewing Children

By understanding the unique challenges and employing these solutions, interviewers can create a more child-friendly and effective interview process, promoting accurate and reliable information gathering from young witnesses.

Pitfalls to Avoid

• Speculation and misinterpretation : Children may misinterpret questions due to immature language and memory skills, leading them to speculate or provide inaccurate information . For example, children might not fully grasp the meaning of words like “before” and “after” .
• Limited information : Directive questions often result in brief answers, restricting the child’s opportunity to provide a full and detailed account of the event.
• Children’s desire to cooperate: Children are generally inclined to answer any question posed by an authority figure, even if they don’t understand the question or know the answer. This can result in inaccurate responses or speculation to please the interviewer.
• Language development : Young children may not understand complex vocabulary, grammatical structures, or abstract concepts . For instance, words like “aunt” and “uncle” can be challenging for children because their meaning shifts depending on the speaker.
• Memory capabilities : Children’s memory abilities are still developing, making them more susceptible to memory errors and suggestibility . Questions that repeatedly cue specific details can inadvertently alter their recollections .
• Attention span and fatigue : Children, especially younger ones, have shorter attention spans and tire more easily than adults.  Lengthy interviews or those with excessive questioning can lead to fatigue and reduce the quality of their responses.
• Reluctance to talk: Children may be hesitant to talk due to various reasons, such as fear of getting into trouble, an inhibited temperament, distrust of unfamiliar adults, or feeling overwhelmed. This can make it challenging to obtain information from them.
• Adopt a child-centered approach: Interviewers prioritize creating a supportive and less intimidating environment by using techniques tailored to the child’s developmental level and cultural background. This includes using developmentally appropriate language, building rapport, and employing a patient and non-judgmental demeanor.
• Emphasize open-ended questions: Instead of relying heavily on focused questions, interviewers prioritize open-ended prompts that encourage children to provide detailed narratives in their own words. They use open-ended invitations like “Tell me everything that happened” or “What happened next?” to elicit more comprehensive and accurate responses.
• Use a questioning cycle: Interviewers combine open-ended invitations with focused prompts to gather specific details while maintaining a conversational flow. This involves cycling back to broader, open-ended prompts after asking focused questions to ensure a thorough understanding of the situation.
• Provide ample time to respond: Recognizing that children may need more time to process information, interviewers provide sufficient wait time, allowing children to respond at their own pace. This patience helps to reduce pressure and encourages more thoughtful responses.
• Build rapport: Establishing rapport is crucial for creating a safe and comfortable space for children to share their experiences. Interviewers achieve this by engaging in neutral conversations, showing genuine interest in the child’s life, and using a calm and reassuring tone.
• Deliver clear interview instructions: Interviewers provide clear and concise instructions, explaining the ground rules of the interview, emphasizing honesty, and encouraging the child to ask for clarification if needed.
• Use interview aids cautiously: While tools like drawings or diagrams can be helpful, interviewers use them with caution, ensuring they don’t lead or suggest information to the child. These aids are primarily used to clarify or elaborate on information the child has already provided verbally.
• Be prepared for multiple interviews: It’s often necessary to conduct multiple interviews to allow children time to process information and recall additional details. Subsequent interviews provide an opportunity to clarify information and explore inconsistencies.

Recording & Transcription

Design choices.

Design choices around recording and engaging closely with transcripts influence analytic insights, as well as practical feasibility. Weighing up relevant tradeoffs is key.

• Audio recording is standard, but video better captures contextual details, which is useful for some topics/analysis approaches. Participants may find video invasive for sensitive research.
• Digital formats enable the sharing of anonymized clips. Additional microphones reduce audio issues.
• Doing all transcription is time-consuming. Outsourcing can save researcher effort but needs confidentiality assurances. Always carefully check outsourced transcripts.
• Online platform auto-captioning can facilitate rapid analysis, but accuracy limitations mean full transcripts remain ideal. Software cleans up caption file formatting.
• Verbatim transcripts best capture nuanced meaning, but the level of detail needed depends on the analysis approach. Referring back to recordings is still advisable during analysis.
• Transcripts versus recordings highlight different interaction elements. Transcripts make overt disagreements clearer through the wording itself. Recordings better convey tone affiliativeness.

Transcribing Interviews & Focus Groups

Here are the steps for transcribing interviews:

• Play back audio/video files to develop an overall understanding of the interview
• Format the transcription document:
• Add line numbers
• Separate interviewer questions and interviewee responses
• Use formatting like bold, italics, etc. to highlight key passages
• Provide sentence-level clarity in the interviewee’s responses while preserving their authentic voice and word choices
• Break longer passages into smaller paragraphs to help with coding
• If translating the interview to another language, use qualified translators and back-translate where possible
• Select a notation system to indicate pauses, emphasis, laughter, interruptions, etc., and adapt it as needed for your data
• Insert screenshots, photos, or documents discussed in the interview at the relevant point in the transcript
• Read through multiple times, revising formatting and notations
• Double-check the accuracy of transcription against audio/videos
• De-identify transcript by removing identifying participant details

The goal is to produce a formatted written record of the verbal interview exchange that captures the meaning and highlights important passages ready for the coding process. Careful transcription is the vital first step in analysis.

Coding Transcripts

The goal of transcription and coding is to systematically transform interview responses into a set of codes and themes that capture key concepts, experiences and beliefs expressed by participants. Taking care with transcription and coding procedures enhances the validity of qualitative analysis .

• Read through the transcript multiple times to become immersed in the details
• Identify manifest/obvious codes and latent/underlying meaning codes
• Highlight insightful participant quotes that capture key concepts (in vivo codes)
• Create a codebook to organize and define codes with examples
• Use an iterative cycle of inductive (data-driven) coding and deductive (theory-driven) coding
• Refine codebook with clear definitions and examples as you code more transcripts
• Collaborate with other coders to establish the reliability of codes

Ethical Issues

Informed consent.

The participant information sheet must give potential interviewees a good idea of what is involved if taking part in the research.

This will include the general topics covered in the interview, where the interview might take place, how long it is expected to last, how it will be recorded, the ways in which participants’ anonymity will be managed, and incentives offered.

It might be considered good practice to consider true informed consent in interview research to require two distinguishable stages:

• Consent to undertake and record the interview and
• Consent to use the material in research after the interview has been conducted and the content known, or even after the interviewee has seen a copy of the transcript and has had a chance to remove sections, if desired.

Power and Vulnerability

• Early feminist views that sensitivity could equalize power differences are likely naive. The interviewer and interviewee inhabit different knowledge spheres and social categories, indicating structural disparities.
• Power fluctuates within interviews. Researchers rely on participation, yet interviewees control openness and can undermine data collection. Assumptions should be avoided.
• Interviews on sensitive topics may feel like quasi-counseling. Interviewers must refrain from dual roles, instead supplying support service details to all participants.
• Interviewees recruited for trauma experiences may reveal more than anticipated. While generating analytic insights, this risks leaving them feeling exposed.
• Ultimately, power balances resist reconciliation. But reflexively analyzing operations of power serves to qualify rather than nullify situtated qualitative accounts.

Some groups, like those with mental health issues, extreme views, or criminal backgrounds, risk being discredited – treated skeptically by researchers.

This creates tensions with qualitative approaches, often having an empathetic ethos seeking to center subjective perspectives. Analysis should balance openness to offered accounts with critically examining stakes and motivations behind them.

• Do you want to record interviews? If so, do you have time to transcribe interview recordings?
• Where will you interview people? Where is the setting with the least distraction?
• How long will each interview take?
• Do you need to address terms of confidentiality?

Do I have to choose either a survey or interviewing method?

No.  In fact, many researchers use a mixed method - interviews can be useful as follow-up to certain respondents to surveys, e.g., to further investigate their responses.

Is training an interviewer important?

Yes, since the interviewer can control the quality of the result, training the interviewer becomes crucial.  If more than one interviewers are involved in your study, it is important to have every interviewer understand the interviewing procedure and rehearse the interviewing process before beginning the formal study.

Interviews can be defined as a qualitative research technique which involves “conducting intensive individual interviews with a small number of respondents to explore their perspectives on a particular idea, program or situation.” [1]

There are three different formats of interviews: structured, semi-structured and unstructured.

Structured interviews consist of a series of pre-determined questions that all interviewees answer in the same order. Data analysis usually tends to be more straightforward because researcher can compare and contrast different answers given to the same questions.

Unstructured interviews are usually the least reliable from research viewpoint, because no questions are prepared prior to the interview and data collection is conducted in an informal manner. Unstructured interviews can be associated with a high level of bias and comparison of answers given by different respondents tends to be difficult due to the differences in formulation of questions.

Semi-structured interviews contain the components of both, structured and unstructured interviews. In semi-structured interviews, interviewer prepares a set of same questions to be answered by all interviewees. At the same time, additional questions might be asked during interviews to clarify and/or further expand certain issues.

Advantages of interviews include possibilities of collecting detailed information about research questions.  Moreover, in in this type of primary data collection researcher has direct control over the flow of process and she has a chance to clarify certain issues during the process if needed. Disadvantages, on the other hand, include longer time requirements and difficulties associated with arranging an appropriate time with perspective sample group members to conduct interviews.

When conducting interviews you should have an open mind and refrain from displaying disagreements in any forms when viewpoints expressed by interviewees contradict your own ideas. Moreover, timing and environment for interviews need to be scheduled effectively. Specifically, interviews need to be conducted in a relaxed environment, free of any forms of pressure for interviewees whatsoever.

Respected scholars warn that “in conducting an interview the interviewer should attempt to create a friendly, non-threatening atmosphere. Much as one does with a cover letter, the interviewer should give a brief, casual introduction to the study; stress the importance of the person’s participation; and assure anonymity, or at least confidentiality, when possible.” [2]

There is a risk of interviewee bias during the primary data collection process and this would seriously compromise the validity of the project findings. Some interviewer bias can be avoided by ensuring that the interviewer does not overreact to responses of the interviewee. Other steps that can be taken to help avoid or reduce interviewer bias include having the interviewer dress inconspicuously and appropriately for the environment and holding the interview in a private setting.  [3]

In-depth interviews are a versatile form of qualitative data collection used by researchers across the social sciences. They allow individuals to explain, in their own words, how they understand and interpret the world around them. Interviews represent a deceptively familiar social encounter in which people interact by asking and answering questions. They are, however, a very particular type of conversation, guided by the researcher and used for specific ends. This dynamic introduces a range of methodological, analytical and ethical challenges, for novice researchers in particular. In this Primer, we focus on the stages and challenges of designing and conducting an interview project and analysing data from it, as well as strategies to overcome such challenges.

Introduction.

In-depth interviews are a qualitative research method that follow a deceptively familiar logic of human interaction: they are conversations where people talk with each other, interact and pose and answer questions 1 . An interview is a specific type of interaction in which — usually and predominantly — a researcher asks questions about someone’s life experience, opinions, dreams, fears and hopes and the interview participant answers the questions 1 .

Interviews will often be used as a standalone method or combined with other qualitative methods, such as focus groups or ethnography, or quantitative methods, such as surveys or experiments. Although interviewing is a frequently used method, it should not be viewed as an easy default for qualitative researchers 2 . Interviews are also not suited to answering all qualitative research questions, but instead have specific strengths that should guide whether or not they are deployed in a research project. Whereas ethnography might be better suited to trying to observe what people do, interviews provide a space for extended conversations that allow the researcher insights into how people think and what they believe. Quantitative surveys also give these kinds of insights, but they use pre-determined questions and scales, privileging breadth over depth and often overlooking harder-to-reach participants.

In-depth interviews can take many different shapes and forms, often with more than one participant or researcher. For example, interviews might be highly structured (using an almost survey-like interview guide), entirely unstructured (taking a narrative and free-flowing approach) or semi-structured (using a topic guide ). Researchers might combine these approaches within a single project depending on the purpose of the interview and the characteristics of the participant. Whatever form the interview takes, researchers should be mindful of the dynamics between interviewer and participant and factor these in at all stages of the project.

In this Primer, we focus on the most common type of interview: one researcher taking a semi-structured approach to interviewing one participant using a topic guide. Focusing on how to plan research using interviews, we discuss the necessary stages of data collection. We also discuss the stages and thought-process behind analysing interview material to ensure that the richness and interpretability of interview material is maintained and communicated to readers. The Primer also tracks innovations in interview methods and discusses the developments we expect over the next 5–10 years.

We wrote this Primer as researchers from sociology, social policy and political science. We note our disciplinary background because we acknowledge that there are disciplinary differences in how interviews are approached and understood as a method.

Experimentation

Here we address research design considerations and data collection issues focusing on topic guide construction and other pragmatics of the interview. We also explore issues of ethics and reflexivity that are crucial throughout the research project.

Research design

Participant selection.

Participants can be selected and recruited in various ways for in-depth interview studies. The researcher must first decide what defines the people or social groups being studied. Often, this means moving from an abstract theoretical research question to a more precise empirical one. For example, the researcher might be interested in how people talk about race in contexts of diversity. Empirical settings in which this issue could be studied could include schools, workplaces or adoption agencies. The best research designs should clearly explain why the particular setting was chosen. Often there are both intrinsic and extrinsic reasons for choosing to study a particular group of people at a specific time and place 3 . Intrinsic motivations relate to the fact that the research is focused on an important specific social phenomenon that has been understudied. Extrinsic motivations speak to the broader theoretical research questions and explain why the case at hand is a good one through which to address them empirically.

Next, the researcher needs to decide which types of people they would like to interview. This decision amounts to delineating the inclusion and exclusion criteria for the study. The criteria might be based on demographic variables, like race or gender, but they may also be context-specific, for example, years of experience in an organization. These should be decided based on the research goals. Researchers should be clear about what characteristics would make an individual a candidate for inclusion in the study (and what would exclude them).

The next step is to identify and recruit the study’s sample . Usually, many more people fit the inclusion criteria than can be interviewed. In cases where lists of potential participants are available, the researcher might want to employ stratified sampling , dividing the list by characteristics of interest before sampling.

When there are no lists, researchers will often employ purposive sampling . Many researchers consider purposive sampling the most useful mode for interview-based research since the number of interviews to be conducted is too small to aim to be statistically representative 4 . Instead, the aim is not breadth, via representativeness, but depth via rich insights about a set of participants. In addition to purposive sampling, researchers often use snowball sampling . Both purposive and snowball sampling can be combined with quota sampling . All three types of sampling aim to ensure a variety of perspectives within the confines of a research project. A goal for in-depth interview studies can be to sample for range, being mindful of recruiting a diversity of participants fitting the inclusion criteria.

Study design

The total number of interviews depends on many factors, including the population studied, whether comparisons are to be made and the duration of interviews. Studies that rely on quota sampling where explicit comparisons are made between groups will require a larger number of interviews than studies focused on one group only. Studies where participants are interviewed over several hours, days or even repeatedly across years will tend to have fewer participants than those that entail a one-off engagement.

Researchers often stop interviewing when new interviews confirm findings from earlier interviews with no new or surprising insights (saturation) 4 , 5 , 6 . As a criterion for research design, saturation assumes that data collection and analysis are happening in tandem and that researchers will stop collecting new data once there is no new information emerging from the interviews. This is not always possible. Researchers rarely have time for systematic data analysis during data collection and they often need to specify their sample in funding proposals prior to data collection. As a result, researchers often draw on existing reports of saturation to estimate a sample size prior to data collection. These suggest between 12 and 20 interviews per category of participant (although researchers have reported saturation with samples that are both smaller and larger than this) 7 , 8 , 9 . The idea of saturation has been critiqued by many qualitative researchers because it assumes that meaning inheres in the data, waiting to be discovered — and confirmed — once saturation has been reached 7 . In-depth interview data are often multivalent and can give rise to different interpretations. The important consideration is, therefore, not merely how many participants are interviewed, but whether one’s research design allows for collecting rich and textured data that provide insight into participants’ understandings, accounts, perceptions and interpretations.

Sometimes, researchers will conduct interviews with more than one participant at a time. Researchers should consider the benefits and shortcomings of such an approach. Joint interviews may, for example, give researchers insight into how caregivers agree or debate childrearing decisions. At the same time, they may be less adaptive to exploring aspects of caregiving that participants may not wish to disclose to each other. In other cases, there may be more than one person interviewing each participant, such as when an interpreter is used, and so it is important to consider during the research design phase how this might shape the dynamics of the interview.

Data collection

Semi-structured interviews are typically organized around a topic guide comprised of an ordered set of broad topics (usually 3–5). Each topic includes a set of questions that form the basis of the discussion between the researcher and participant (Fig.  1 ). These topics are organized around key concepts that the researcher has identified (for example, through a close study of prior research, or perhaps through piloting a small, exploratory study) 5 .

a | Elaborated topics the researcher wants to cover in the interview and example questions. b | An example topic arc. Using such an arc, one can think flexibly about the order of topics. Considering the main question for each topic will help to determine the best order for the topics. After conducting some interviews, the researcher can move topics around if a different order seems to make sense.

Topic guide

One common way to structure a topic guide is to start with relatively easy, open-ended questions (Table  1 ). Opening questions should be related to the research topic but broad and easy to answer, so that they help to ease the participant into conversation.

After these broad, opening questions, the topic guide may move into topics that speak more directly to the overarching research question. The interview questions will be accompanied by probes designed to elicit concrete details and examples from the participant (see Table  1 ).

Abstract questions are often easier for participants to answer once they have been asked more concrete questions. In our experience, for example, questions about feelings can be difficult for some participants to answer, but when following probes concerning factual experiences these questions can become less challenging. After the main themes of the topic guide have been covered, the topic guide can move onto closing questions. At this stage, participants often repeat something they have said before, although they may sometimes introduce a new topic.

Interviews are especially well suited to gaining a deeper insight into people’s experiences. Getting these insights largely depends on the participants’ willingness to talk to the researcher. We recommend designing open-ended questions that are more likely to elicit an elaborated response and extended reflection from participants rather than questions that can be answered with yes or no.

Questions should avoid foreclosing the possibility that the participant might disagree with the premise of the question. Take for example the question: “Do you support the new family-friendly policies?” This question minimizes the possibility of the participant disagreeing with the premise of this question, which assumes that the policies are ‘family-friendly’ and asks for a yes or no answer. Instead, asking more broadly how a participant feels about the specific policy being described as ‘family-friendly’ (for example, a work-from-home policy) allows them to express agreement, disagreement or impartiality and, crucially, to explain their reasoning 10 .

For an uninterrupted interview that will last between 90 and 120 minutes, the topic guide should be one to two single-spaced pages with questions and probes. Ideally, the researcher will memorize the topic guide before embarking on the first interview. It is fine to carry a printed-out copy of the topic guide but memorizing the topic guide ahead of the interviews can often make the interviewer feel well prepared in guiding the participant through the interview process.

Although the topic guide helps the researcher stay on track with the broad areas they want to cover, there is no need for the researcher to feel tied down by the topic guide. For instance, if a participant brings up a theme that the researcher intended to discuss later or a point the researcher had not anticipated, the researcher may well decide to follow the lead of the participant. The researcher’s role extends beyond simply stating the questions; it entails listening and responding, making split-second decisions about what line of inquiry to pursue and allowing the interview to proceed in unexpected directions.

Optimizing the interview

The ideal place for an interview will depend on the study and what is feasible for participants. Generally, a place where the participant and researcher can both feel relaxed, where the interview can be uninterrupted and where noise or other distractions are limited is ideal. But this may not always be possible and so the researcher needs to be prepared to adapt their plans within what is feasible (and desirable for participants).

Another key tool for the interview is a recording device (assuming that permission for recording has been given). Recording can be important to capture what the participant says verbatim. Additionally, it can allow the researcher to focus on determining what probes and follow-up questions they want to pursue rather than focusing on taking notes. Sometimes, however, a participant may not allow the researcher to record, or the recording may fail. If the interview is not recorded we suggest that the researcher takes brief notes during the interview, if feasible, and then thoroughly make notes immediately after the interview and try to remember the participant’s facial expressions, gestures and tone of voice. Not having a recording of an interview need not limit the researcher from getting analytical value from it.

As soon as possible after each interview, we recommend that the researcher write a one-page interview memo comprising three key sections. The first section should identify two to three important moments from the interview. What constitutes important is up to the researcher’s discretion 9 . The researcher should note down what happened in these moments, including the participant’s facial expressions, gestures, tone of voice and maybe even the sensory details of their surroundings. This exercise is about capturing ethnographic detail from the interview. The second part of the interview memo is the analytical section with notes on how the interview fits in with previous interviews, for example, where the participant’s responses concur or diverge from other responses. The third part consists of a methodological section where the researcher notes their perception of their relationship with the participant. The interview memo allows the researcher to think critically about their positionality and practice reflexivity — key concepts for an ethical and transparent research practice in qualitative methodology 11 , 12 .

Ethics and reflexivity

All elements of an in-depth interview can raise ethical challenges and concerns. Good ethical practice in interview studies often means going beyond the ethical procedures mandated by institutions 13 . While discussions and requirements of ethics can differ across disciplines, here we focus on the most pertinent considerations for interviews across the research process for an interdisciplinary audience.

Ethical considerations prior to interview

Before conducting interviews, researchers should consider harm minimization, informed consent, anonymity and confidentiality, and reflexivity and positionality. It is important for the researcher to develop their own ethical sensitivities and sensibilities by gaining training in interview and qualitative methods, reading methodological and field-specific texts on interviews and ethics and discussing their research plans with colleagues.

Researchers should map the potential harm to consider how this can be minimized. Primarily, researchers should consider harm from the participants’ perspective (Box  1 ). But, it is also important to consider and plan for potential harm to the researcher, research assistants, gatekeepers, future researchers and members of the wider community 14 . Even the most banal of research topics can potentially pose some form of harm to the participant, researcher and others — and the level of harm is often highly context-dependent. For example, a research project on religion in society might have very different ethical considerations in a democratic versus authoritarian research context because of how openly or not such topics can be discussed and debated 15 .

The researcher should consider how they will obtain and record informed consent (for example, written or oral), based on what makes the most sense for their research project and context 16 . Some institutions might specify how informed consent should be gained. Regardless of how consent is obtained, the participant must be made aware of the form of consent, the intentions and procedures of the interview and potential forms of harm and benefit to the participant or community before the interview commences. Moreover, the participant must agree to be interviewed before the interview commences. If, in addition to interviews, the study contains an ethnographic component, it is worth reading around this topic (see, for example, Murphy and Dingwall 17 ). Informed consent must also be gained for how the interview will be recorded before the interview commences. These practices are important to ensure the participant is contributing on a voluntary basis. It is also important to remind participants that they can withdraw their consent at any time during the interview and for a specified period after the interview (to be decided with the participant). The researcher should indicate that participants can ask for anything shared to be off the record and/or not disseminated.

In terms of anonymity and confidentiality, it is standard practice when conducting interviews to agree not to use (or even collect) participants’ names and personal details that are not pertinent to the study. Anonymizing can often be the safer option for minimizing harm to participants as it is hard to foresee all the consequences of de-anonymizing, even if participants agree. Regardless of what a researcher decides, decisions around anonymity must be agreed with participants during the process of gaining informed consent and respected following the interview.

Although not all ethical challenges can be foreseen or planned for 18 , researchers should think carefully — before the interview — about power dynamics, participant vulnerability, emotional state and interactional dynamics between interviewer and participant, even when discussing low-risk topics. Researchers may then wish to plan for potential ethical issues, for example by preparing a list of relevant organizations to which participants can be signposted. A researcher interviewing a participant about debt, for instance, might prepare in advance a list of debt advice charities, organizations and helplines that could provide further support and advice. It is important to remember that the role of an interviewer is as a researcher rather than as a social worker or counsellor because researchers may not have relevant and requisite training in these other domains.

Box 1 Mapping potential forms of harm

Social: researchers should avoid causing any relational detriment to anyone in the course of interviews, for example, by sharing information with other participants or causing interview participants to be shunned or mistreated by their community as a result of participating.

Economic: researchers should avoid causing financial detriment to anyone, for example, by expecting them to pay for transport to be interviewed or to potentially lose their job as a result of participating.

Physical: researchers should minimize the risk of anyone being exposed to violence as a result of the research both from other individuals or from authorities, including police.

Psychological: researchers should minimize the risk of causing anyone trauma (or re-traumatization) or psychological anguish as a result of the research; this includes not only the participant but importantly the researcher themselves and anyone that might read or analyse the transcripts, should they contain triggering information.

Political: researchers should minimize the risk of anyone being exposed to political detriment as a result of the research, such as retribution.

Professional/reputational: researchers should minimize the potential for reputational damage to anyone connected to the research (this includes ensuring good research practices so that any researchers involved are not harmed reputationally by being involved with the research project).

The task here is not to map exhaustively the potential forms of harm that might pertain to a particular research project (that is the researcher’s job and they should have the expertise most suited to mapping such potential harms relative to the specific project) but to demonstrate the breadth of potential forms of harm.

Ethical considerations post-interview

Researchers should consider how interview data are stored, analysed and disseminated. If participants have been offered anonymity and confidentiality, data should be stored in a way that does not compromise this. For example, researchers should consider removing names and any other unnecessary personal details from interview transcripts, password-protecting and encrypting files and using pseudonyms to label and store all interview data. It is also important to address where interview data are taken (for example, across borders in particular where interview data might be of interest to local authorities) and how this might affect the storage of interview data.

Examining how the researcher will represent participants is a paramount ethical consideration both in the planning stages of the interview study and after it has been conducted. Dissemination strategies also need to consider questions of anonymity and representation. In small communities, even if participants are given pseudonyms, it might be obvious who is being described. Anonymizing not only the names of those participating but also the research context is therefore a standard practice 19 . With particularly sensitive data or insights about the participant, it is worth considering describing participants in a more abstract way rather than as specific individuals. These practices are important both for protecting participants’ anonymity but can also affect the ability of the researcher and others to return ethically to the research context and similar contexts 20 .

Reflexivity and positionality

Reflexivity and positionality mean considering the researcher’s role and assumptions in knowledge production 13 . A key part of reflexivity is considering the power relations between the researcher and participant within the interview setting, as well as how researchers might be perceived by participants. Further, researchers need to consider how their own identities shape the kind of knowledge and assumptions they bring to the interview, including how they approach and ask questions and their analysis of interviews (Box  2 ). Reflexivity is a necessary part of developing ethical sensibility as a researcher by adapting and reflecting on how one engages with participants. Participants should not feel judged, for example, when they share information that researchers might disagree with or find objectionable. How researchers deal with uncomfortable moments or information shared by participants is at their discretion, but they should consider how they will react both ahead of time and in the moment.

Researchers can develop their reflexivity by considering how they themselves would feel being asked these interview questions or represented in this way, and then adapting their practice accordingly. There might be situations where these questions are not appropriate in that they unduly centre the researchers’ experiences and worldview. Nevertheless, these prompts can provide a useful starting point for those beginning their reflexive journey and developing an ethical sensibility.

Reflexivity and ethical sensitivities require active reflection throughout the research process. For example, researchers should take care in interview memos and their notes to consider their assumptions, potential preconceptions, worldviews and own identities prior to and after interviews (Box  2 ). Checking in with assumptions can be a way of making sure that researchers are paying close attention to their own theoretical and analytical biases and revising them in accordance with what they learn through the interviews. Researchers should return to these notes (especially when analysing interview material), to try to unpack their own effects on the research process as well as how participants positioned and engaged with them.

Box 2 Aspects to reflect on reflexively

For reflexive engagement, and understanding the power relations being co-constructed and (re)produced in interviews, it is necessary to reflect, at a minimum, on the following.

Ethnicity, race and nationality, such as how does privilege stemming from race or nationality operate between the researcher, the participant and research context (for example, a researcher from a majority community may be interviewing a member of a minority community)

Gender and sexuality, see above on ethnicity, race and nationality

Social class, and in particular the issue of middle-class bias among researchers when formulating research and interview questions

Economic security/precarity, see above on social class and thinking about the researcher’s relative privilege and the source of biases that stem from this

Educational experiences and privileges, see above

Disciplinary biases, such as how the researcher’s discipline/subfield usually approaches these questions, possibly normalizing certain assumptions that might be contested by participants and in the research context

Political and social values

Lived experiences and other dimensions of ourselves that affect and construct our identity as researchers

In this section, we discuss the next stage of an interview study, namely, analysing the interview data. Data analysis may begin while more data are being collected. Doing so allows early findings to inform the focus of further data collection, as part of an iterative process across the research project. Here, the researcher is ultimately working towards achieving coherence between the data collected and the findings produced to answer successfully the research question(s) they have set.

The two most common methods used to analyse interview material across the social sciences are thematic analysis 21 and discourse analysis 22 . Thematic analysis is a particularly useful and accessible method for those starting out in analysis of qualitative data and interview material as a method of coding data to develop and interpret themes in the data 21 . Discourse analysis is more specialized and focuses on the role of discourse in society by paying close attention to the explicit, implicit and taken-for-granted dimensions of language and power 22 , 23 . Although thematic and discourse analysis are often discussed as separate techniques, in practice researchers might flexibly combine these approaches depending on the object of analysis. For example, those intending to use discourse analysis might first conduct thematic analysis as a way to organize and systematize the data. The object and intention of analysis might differ (for example, developing themes or interrogating language), but the questions facing the researcher (such as whether to take an inductive or deductive approach to analysis) are similar.

Preparing data

Data preparation is an important step in the data analysis process. The researcher should first determine what comprises the corpus of material and in what form it will it be analysed. The former refers to whether, for example, alongside the interviews themselves, analytic memos or observational notes that may have been taken during data collection will also be directly analysed. The latter refers to decisions about how the verbal/audio interview data will be transformed into a written form, making it suitable for processes of data analysis. Typically, interview audio recordings are transcribed to produce a written transcript. It is important to note that the process of transcription is one of transformation. The verbal interview data are transformed into a written transcript through a series of decisions that the researcher must make. The researcher should consider the effect of mishearing what has been said or how choosing to punctuate a sentence in a particular way will affect the final analysis.

Box  3 shows an example transcript excerpt from an interview with a teacher conducted by Teeger as part of her study of history education in post-apartheid South Africa 24 (Box  3 ). Seeing both the questions and the responses means that the reader can contextualize what the participant (Ms Mokoena) has said. Throughout the transcript the researcher has used square brackets, for example to indicate a pause in speech, when Ms Mokoena says “it’s [pause] it’s a difficult topic”. The transcription choice made here means that we see that Ms Mokoena has taken time to pause, perhaps to search for the right words, or perhaps because she has a slight apprehension. Square brackets are also included as an overt act of communication to the reader. When Ms Mokoena says “ja”, the English translation (“yes”) of the word in Afrikaans is placed in square brackets to ensure that the reader can follow the meaning of the speech.

Decisions about what to include when transcribing will be hugely important for the direction and possibilities of analysis. Researchers should decide what they want to capture in the transcript, based on their analytic focus. From a (post)positivist perspective 25 , the researcher may be interested in the manifest content of the interview (such as what is said, not how it is said). In that case, they may choose to transcribe intelligent verbatim . From a constructivist perspective 25 , researchers may choose to record more aspects of speech (including, for example, pauses, repetitions, false starts, talking over one another) so that these features can be analysed. Those working from this perspective argue that to recognize the interactional nature of the interview setting adequately and to avoid misinterpretations, features of interaction (pauses, overlaps between speakers and so on) should be preserved in transcription and therefore in the analysis 10 . Readers interested in learning more should consult Potter and Hepburn’s summary of how to present interaction through transcription of interview data 26 .

The process of analysing semi-structured interviews might be thought of as a generative rather than an extractive enterprise. Findings do not already exist within the interview data to be discovered. Rather, researchers create something new when analysing the data by applying their analytic lens or approach to the transcripts. At a high level, there are options as to what researchers might want to glean from their interview data. They might be interested in themes, whereby they identify patterns of meaning across the dataset 21 . Alternatively, they may focus on discourse(s), looking to identify how language is used to construct meanings and therefore how language reinforces or produces aspects of the social world 27 . Alternatively, they might look at the data to understand narrative or biographical elements 28 .

A further overarching decision to make is the extent to which researchers bring predetermined framings or understandings to bear on their data, or instead begin from the data themselves to generate an analysis. One way of articulating this is the extent to which researchers take a deductive approach or an inductive approach to analysis. One example of a truly inductive approach is grounded theory, whereby the aim of the analysis is to build new theory, beginning with one’s data 6 , 29 . In practice, researchers using thematic and discourse analysis often combine deductive and inductive logics and describe their process instead as iterative (referred to also as an abductive approach ) 30 , 31 . For example, researchers may decide that they will apply a given theoretical framing, or begin with an initial analytic framework, but then refine or develop these once they begin the process of analysis.

Box 3 Excerpt of interview transcript (from Teeger 24 )

Interviewer : Maybe you could just start by talking about what it’s like to teach apartheid history.

Ms Mokoena : It’s a bit challenging. You’ve got to accommodate all the kids in the class. You’ve got to be sensitive to all the racial differences. You want to emphasize the wrongs that were done in the past but you also want to, you know, not to make kids feel like it’s their fault. So you want to use the wrongs of the past to try and unite the kids …

Interviewer : So what kind of things do you do?

Ms Mokoena : Well I normally highlight the fact that people that were struggling were not just the blacks, it was all the races. And I give examples of the people … from all walks of life, all races, and highlight how they suffered as well as a result of apartheid, particularly the whites… . What I noticed, particularly my first year of teaching apartheid, I noticed that the black kids made the others feel responsible for what happened… . I had a lot of fights…. A lot of kids started hating each other because, you know, the others are white and the others were black. And they started saying, “My mother is a domestic worker because she was never allowed an opportunity to get good education.” …

Interviewer : I didn’t see any of that now when I was observing.

Ms Mokoena : … Like I was saying I think that because of the re-emphasis of the fact that, look, everybody did suffer one way or the other, they sort of got to see that it was everybody’s struggle … . They should now get to understand that that’s why we’re called a Rainbow Nation. Not everybody agreed with apartheid and not everybody suffered. Even all the blacks, not all blacks got to feel what the others felt . So ja [yes], it’s [pause] it’s a difficult topic, ja . But I think if you get the kids to understand why we’re teaching apartheid in the first place and you show the involvement of all races in all the different sides , then I think you have managed to teach it properly. So I think because of my inexperience then — that was my first year of teaching history — so I think I — maybe I over-emphasized the suffering of the blacks versus the whites [emphasis added].

From data to codes

Coding data is a key building block shared across many approaches to data analysis. Coding is a way of organizing and describing data, but is also ultimately a way of transforming data to produce analytic insights. The basic practice of coding involves highlighting a segment of text (this may be a sentence, a clause or a longer excerpt) and assigning a label to it. The aim of the label is to communicate some sort of summary of what is in the highlighted piece of text. Coding is an iterative process, whereby researchers read and reread their transcripts, applying and refining their codes, until they have a coding frame (a set of codes) that is applied coherently across the dataset and that captures and communicates the key features of what is contained in the data as it relates to the researchers’ analytic focus.

What one codes for is entirely contingent on the focus of the research project and the choices the researcher makes about the approach to analysis. At first, one might apply descriptive codes, summarizing what is contained in the interviews. It is rarely desirable to stop at this point, however, because coding is a tool to move from describing the data to interpreting the data. Suppose the researcher is pursuing some version of thematic analysis. In that case, it might be that the objects of coding are aspects of reported action, emotions, opinions, norms, relationships, routines, agreement/disagreement and change over time. A discourse analysis might instead code for different types of speech acts, tropes, linguistic or rhetorical devices. Multiple types of code might be generated within the same research project. What is important is that researchers are aware of the choices they are making in terms of what they are coding for. Moreover, through the process of refinement, the aim is to produce a set of discrete codes — in which codes are conceptually distinct, as opposed to overlapping. By using the same codes across the dataset, the researcher can capture commonalities across the interviews. This process of refinement involves relabelling codes and reorganizing how and where they are applied in the dataset.

From coding to analysis and writing

Data analysis is also an iterative process in which researchers move closer to and further away from the data. As they move away from the data, they synthesize their findings, thus honing and articulating their analytic insights. As they move closer to the data, they ground these insights in what is contained in the interviews. The link should not be broken between the data themselves and higher-order conceptual insights or claims being made. Researchers must be able to show evidence for their claims in the data. Figure  2 summarizes this iterative process and suggests the sorts of activities involved at each stage more concretely.

As well as going through steps 1 to 6 in order, the researcher will also go backwards and forwards between stages. Some stages will themselves be a forwards and backwards processing of coding and refining when working across different interview transcripts.

At the stage of synthesizing, there are some common quandaries. When dealing with a dataset consisting of multiple interviews, there will be salient and minority statements across different participants, or consensus or dissent on topics of interest to the researcher. A strength of qualitative interviews is that we can build in these nuances and variations across our data as opposed to aggregating them away. When exploring and reporting data, researchers should be asking how different findings are patterned and which interviews contain which codes, themes or tropes. Researchers should think about how these variations fit within the longer flow of individual interviews and what these variations tell them about the nature of their substantive research interests.

A further consideration is how to approach analysis within and across interview data. Researchers may look at one individual code, to examine the forms it takes across different participants and what they might be able to summarize about this code in the round. Alternatively, they might look at how a code or set of codes pattern across the account of one participant, to understand the code(s) in a more contextualized way. Further analysis might be done according to different sampling characteristics, where researchers group together interviews based on certain demographic characteristics and explore these together.

When it comes to writing up and presenting interview data, key considerations tend to rest on what is often termed transparency. When presenting the findings of an interview-based study, the reader should be able to understand and trace what the stated findings are based upon. This process typically involves describing the analytic process, how key decisions were made and presenting direct excerpts from the data. It is important to account for how the interview was set up and to consider the active part that the researcher has played in generating the data 32 . Quotes from interviews should not be thought of as merely embellishing or adding interest to a final research output. Rather, quotes serve the important function of connecting the reader directly to the underlying data. Quotes, therefore, should be chosen because they provide the reader with the most apt insight into what is being discussed. It is good practice to report not just on what participants said, but also on the questions that were asked to elicit the responses.

Researchers have increasingly used specialist qualitative data analysis software to organize and analyse their interview data, such as NVivo or ATLAS.ti. It is important to remember that such software is a tool for, rather than an approach or technique of, analysis. That said, software also creates a wide range of possibilities in terms of what can be done with the data. As researchers, we should reflect on how the range of possibilities of a given software package might be shaping our analytical choices and whether these are choices that we do indeed want to make.

Applications

This section reviews how and why in-depth interviews have been used by researchers studying gender, education and inequality, nationalism and ethnicity and the welfare state. Although interviews can be employed as a method of data collection in just about any social science topic, the applications below speak directly to the authors’ expertise and cutting-edge areas of research.

When it comes to the broad study of gender, in-depth interviews have been invaluable in shaping our understanding of how gender functions in everyday life. In a study of the US hedge fund industry (an industry dominated by white men), Tobias Neely was interested in understanding the factors that enable white men to prosper in the industry 33 . The study comprised interviews with 45 hedge fund workers and oversampled women of all races and men of colour to capture a range of experiences and beliefs. Tobias Neely found that practices of hiring, grooming and seeding are key to maintaining white men’s dominance in the industry. In terms of hiring, the interviews clarified that white men in charge typically preferred to hire people like themselves, usually from their extended networks. When women were hired, they were usually hired to less lucrative positions. In terms of grooming, Tobias Neely identifies how older and more senior men in the industry who have power and status will select one or several younger men as their protégés, to include in their own elite networks. Finally, in terms of her concept of seeding, Tobias Neely describes how older men who are hedge fund managers provide the seed money (often in the hundreds of millions of dollars) for a hedge fund to men, often their own sons (but not their daughters). These interviews provided an in-depth look into gendered and racialized mechanisms that allow white men to flourish in this industry.

Research by Rao draws on dozens of interviews with men and women who had lost their jobs, some of the participants’ spouses and follow-up interviews with about half the sample approximately 6 months after the initial interview 34 . Rao used interviews to understand the gendered experience and understanding of unemployment. Through these interviews, she found that the very process of losing their jobs meant different things for men and women. Women often saw job loss as being a personal indictment of their professional capabilities. The women interviewed often referenced how years of devaluation in the workplace coloured their interpretation of their job loss. Men, by contrast, were also saddened by their job loss, but they saw it as part and parcel of a weak economy rather than a personal failing. How these varied interpretations occurred was tied to men’s and women’s very different experiences in the workplace. Further, through her analysis of these interviews, Rao also showed how these gendered interpretations had implications for the kinds of jobs men and women sought to pursue after job loss. Whereas men remained tied to participating in full-time paid work, job loss appeared to be a catalyst pushing some of the women to re-evaluate their ties to the labour force.

In a study of workers in the tech industry, Hart used interviews to explain how individuals respond to unwanted and ambiguously sexual interactions 35 . Here, the researcher used interviews to allow participants to describe how these interactions made them feel and act and the logics of how they interpreted, classified and made sense of them 35 . Through her analysis of these interviews, Hart showed that participants engaged in a process she termed “trajectory guarding”, whereby they sought to monitor unwanted and ambiguously sexual interactions to avoid them from escalating. Yet, as Hart’s analysis proficiently demonstrates, these very strategies — which protect these workers sexually — also undermined their workplace advancement.

Drawing on interviews, these studies have helped us to understand better how gendered mechanisms, gendered interpretations and gendered interactions foster gender inequality when it comes to paid work. Methodologically, these studies illuminate the power of interviews to reveal important aspects of social life.

Nationalism and ethnicity

Traditionally, nationalism has been studied from a top-down perspective, through the lens of the state or using historical methods; in other words, in-depth interviews have not been a common way of collecting data to study nationalism. The methodological turn towards everyday nationalism has encouraged more scholars to go to the field and use interviews (and ethnography) to understand nationalism from the bottom up: how people talk about, give meaning, understand, navigate and contest their relation to nation, national identification and nationalism 36 , 37 , 38 , 39 . This turn has also addressed the gap left by those studying national and ethnic identification via quantitative methods, such as surveys.

Surveys can enumerate how individuals ascribe to categorical forms of identification 40 . However, interviews can question the usefulness of such categories and ask whether these categories are reflected, or resisted, by participants in terms of the meanings they give to identification 41 , 42 . Categories often pitch identification as a mutually exclusive choice; but identification might be more complex than such categories allow. For example, some might hybridize these categories or see themselves as moving between and across categories 43 . Hearing how people talk about themselves and their relation to nations, states and ethnicities, therefore, contributes substantially to the study of nationalism and national and ethnic forms of identification.

One particular approach to studying these topics, whether via everyday nationalism or alternatives, is that of using interviews to capture both articulations and narratives of identification, relations to nationalism and the boundaries people construct. For example, interviews can be used to gather self–other narratives by studying how individuals construct I–we–them boundaries 44 , including how participants talk about themselves, who participants include in their various ‘we’ groupings and which and how participants create ‘them’ groupings of others, inserting boundaries between ‘I/we’ and ‘them’. Overall, interviews hold great potential for listening to participants and understanding the nuances of identification and the construction of boundaries from their point of view.

Education and inequality

Scholars of social stratification have long noted that the school system often reproduces existing social inequalities. Carter explains that all schools have both material and sociocultural resources 45 . When children from different backgrounds attend schools with different material resources, their educational and occupational outcomes are likely to vary. Such material resources are relatively easy to measure. They are operationalized as teacher-to-student ratios, access to computers and textbooks and the physical infrastructure of classrooms and playgrounds.

Drawing on Bourdieusian theory 46 , Carter conceptualizes the sociocultural context as the norms, values and dispositions privileged within a social space 45 . Scholars have drawn on interviews with students and teachers (as well as ethnographic observations) to show how schools confer advantages on students from middle-class families, for example, by rewarding their help-seeking behaviours 47 . Focusing on race, researchers have revealed how schools can remain socioculturally white even as they enrol a racially diverse student population. In such contexts, for example, teachers often misrecognize the aesthetic choices made by students of colour, wrongly inferring that these students’ tastes in clothing and music reflect negative orientations to schooling 48 , 49 , 50 . These assessments can result in disparate forms of discipline and may ultimately shape educators’ assessments of students’ academic potential 51 .

Further, teachers and administrators tend to view the appropriate relationship between home and school in ways that resonate with white middle-class parents 52 . These parents are then able to advocate effectively for their children in ways that non-white parents are not 53 . In-depth interviews are particularly good at tapping into these understandings, revealing the mechanisms that confer privilege on certain groups of students and thereby reproduce inequality.

In addition, interviews can shed light on the unequal experiences that young people have within educational institutions, as the views of dominant groups are affirmed while those from disadvantaged backgrounds are delegitimized. For example, Teeger’s interviews with South African high schoolers showed how — because racially charged incidents are often framed as jokes in the broader school culture — Black students often feel compelled to ignore and keep silent about the racism they experience 54 . Interviews revealed that Black students who objected to these supposed jokes were coded by other students as serious or angry. In trying to avoid such labels, these students found themselves unable to challenge the racism they experienced. Interviews give us insight into these dynamics and help us see how young people understand and interpret the messages transmitted in schools — including those that speak to issues of inequality in their local school contexts as well as in society more broadly 24 , 55 .

The welfare state

In-depth interviews have also proved to be an important method for studying various aspects of the welfare state. By welfare state, we mean the social institutions relating to the economic and social wellbeing of a state’s citizens. Notably, using interviews has been useful to look at how policy design features are experienced and play out on the ground. Interviews have often been paired with large-scale surveys to produce mixed-methods study designs, therefore achieving both breadth and depth of insights.

In-depth interviews provide the opportunity to look behind policy assumptions or how policies are designed from the top down, to examine how these play out in the lives of those affected by the policies and whose experiences might otherwise be obscured or ignored. For example, the Welfare Conditionality project used interviews to critique the assumptions that conditionality (such as, the withdrawal of social security benefits if recipients did not perform or meet certain criteria) improved employment outcomes and instead showed that conditionality was harmful to mental health, living standards and had many other negative consequences 56 . Meanwhile, combining datasets from two small-scale interview studies with recipients allowed Summers and Young to critique assumptions around the simplicity that underpinned the design of Universal Credit in 2020, for example, showing that the apparently simple monthly payment design instead burdened recipients with additional money management decisions and responsibilities 57 .

Similarly, the Welfare at a (Social) Distance project used a mixed-methods approach in a large-scale study that combined national surveys with case studies and in-depth interviews to investigate the experience of claiming social security benefits during the COVID-19 pandemic. The interviews allowed researchers to understand in detail any issues experienced by recipients of benefits, such as delays in the process of claiming, managing on a very tight budget and navigating stigma and claiming 58 .

These applications demonstrate the multi-faceted topics and questions for which interviews can be a relevant method for data collection. These applications highlight not only the relevance of interviews, but also emphasize the key added value of interviews, which might be missed by other methods (surveys, in particular). Interviews can expose and question what is taken for granted and directly engage with communities and participants that might otherwise be ignored, obscured or marginalized.

Reproducibility and data deposition

There is a robust, ongoing debate about reproducibility in qualitative research, including interview studies. In some research paradigms, reproducibility can be a way of interrogating the rigour and robustness of research claims, by seeing whether these hold up when the research process is repeated. Some scholars have suggested that although reproducibility may be challenging, researchers can facilitate it by naming the place where the research was conducted, naming participants, sharing interview and fieldwork transcripts (anonymized and de-identified in cases where researchers are not naming people or places) and employing fact-checkers for accuracy 11 , 59 , 60 .

In addition to the ethical concerns of whether de-anonymization is ever feasible or desirable, it is also important to address whether the replicability of interview studies is meaningful. For example, the flexibility of interviews allows for the unexpected and the unforeseen to be incorporated into the scope of the research 61 . However, this flexibility means that we cannot expect reproducibility in the conventional sense, given that different researchers will elicit different types of data from participants. Sharing interview transcripts with other researchers, for instance, downplays the contextual nature of an interview.

Drawing on Bauer and Gaskell, we propose several measures to enhance rigour in qualitative research: transparency, grounding interpretations and aiming for theoretical transferability and significance 62 .

Researchers should be transparent when describing their methodological choices. Transparency means documenting who was interviewed, where and when (without requiring de-anonymization, for example, by documenting their characteristics), as well as the questions they were asked. It means carefully considering who was left out of the interviews and what that could mean for the researcher’s findings. It also means carefully considering who the researcher is and how their identity shaped the research process (integrating and articulating reflexivity into whatever is written up).

Second, researchers should ground their interpretations in the data. Grounding means presenting the evidence upon which the interpretation relies. Quotes and extracts should be extensive enough to allow the reader to evaluate whether the researcher’s interpretations are grounded in the data. At each step, researchers should carefully compare their own explanations and interpretations with alternative explanations. Doing so systematically and frequently allows researchers to become more confident in their claims. Here, researchers should justify the link between data and analysis by using quotes to justify and demonstrate the analytical point, while making sure the analytical point offers an interpretation of quotes (Box  4 ).

An important step in considering alternative explanations is to seek out disconfirming evidence 4 , 63 . This involves looking for instances where participants deviate from what the majority are saying and thus bring into question the theory (or explanation) that the researcher is developing. Careful analysis of such examples can often demonstrate the salience and meaning of what appears to be the norm (see Table  2 for examples) 54 . Considering alternative explanations and paying attention to disconfirming evidence allows the researcher to refine their own theories in respect of the data.

Finally, researchers should aim for theoretical transferability and significance in their discussions of findings. One way to think about this is to imagine someone who is not interested in the empirical study. Articulating theoretical transferability and significance usually takes the form of broadening out from the specific findings to consider explicitly how the research has refined or altered prior theoretical approaches. This process also means considering under what other conditions, aside from those of the study, the researcher thinks their theoretical revision would be supported by and why. Importantly, it also includes thinking about the limitations of one’s own approach and where the theoretical implications of the study might not hold.

Box 4 An example of grounding interpretations in data (from Rao 34 )

In an article explaining how unemployed men frame their job loss as a pervasive experience, Rao writes the following: “Unemployed men in this study understood unemployment to be an expected aspect of paid work in the contemporary United States. Robert, a white unemployed communications professional, compared the economic landscape after the Great Recession with the tragic events of September 11, 2001:

Part of your post-9/11 world was knowing people that died as a result of terrorism. The same thing is true with the [Great] Recession, right? … After the Recession you know somebody who was unemployed … People that really should be working.

The pervasiveness of unemployment rendered it normal, as Robert indicates.”

Here, the link between the quote presented and the analytical point Rao is making is clear: the analytical point is grounded in a quote and an interpretation of the quote is offered 34 .

Limitations and optimizations

When deciding which research method to use, the key question is whether the method provides a good fit for the research questions posed. In other words, researchers should consider whether interviews will allow them to successfully access the social phenomena necessary to answer their question(s) and whether the interviews will do so more effectively than other methods. Table  3 summarizes the major strengths and limitations of interviews. However, the accompanying text below is organized around some key issues, where relative strengths and weaknesses are presented alongside each other, the aim being that readers should think about how these can be balanced and optimized in relation to their own research.

Breadth versus depth of insight

Achieving an overall breadth of insight, in a statistically representative sense, is not something that is possible or indeed desirable when conducting in-depth interviews. Instead, the strength of conducting interviews lies in their ability to generate various sorts of depth of insight. The experiences or views of participants that can be accessed by conducting interviews help us to understand participants’ subjective realities. The challenge, therefore, is for researchers to be clear about why depth of insight is the focus and what we should aim to glean from these types of insight.

Naturalistic or artificial interviews

Interviews make use of a form of interaction with which people are familiar 64 . By replicating a naturalistic form of interaction as a tool to gather social science data, researchers can capitalize on people’s familiarity and expectations of what happens in a conversation. This familiarity can also be a challenge, as people come to the interview with preconceived ideas about what this conversation might be for or about. People may draw on experiences of other similar conversations when taking part in a research interview (for example, job interviews, therapy sessions, confessional conversations, chats with friends). Researchers should be aware of such potential overlaps and think through their implications both in how the aims and purposes of the research interview are communicated to participants and in how interview data are interpreted.

Further, some argue that a limitation of interviews is that they are an artificial form of data collection. By taking people out of their daily lives and asking them to stand back and pass comment, we are creating a distance that makes it difficult to use such data to say something meaningful about people’s actions, experiences and views. Other approaches, such as ethnography, might be more suitable for tapping into what people actually do, as opposed to what they say they do 65 .

Dynamism and replicability

Interviews following a semi-structured format offer flexibility both to the researcher and the participant. As the conversation develops, the interlocutors can explore the topics raised in much more detail, if desired, or pass over ones that are not relevant. This flexibility allows for the unexpected and the unforeseen to be incorporated into the scope of the research.

However, this flexibility has a related challenge of replicability. Interviews cannot be reproduced because they are contingent upon the interaction between the researcher and the participant in that given moment of interaction. In some research paradigms, replicability can be a way of interrogating the robustness of research claims, by seeing whether they hold when they are repeated. This is not a useful framework to bring to in-depth interviews and instead quality criteria (such as transparency) tend to be employed as criteria of rigour.

Accessing the private and personal

Interviews have been recognized for their strength in accessing private, personal issues, which participants may feel more comfortable talking about in a one-to-one conversation. Furthermore, interviews are likely to take a more personable form with their extended questions and answers, perhaps making a participant feel more at ease when discussing sensitive topics in such a context. There is a similar, but separate, argument made about accessing what are sometimes referred to as vulnerable groups, who may be difficult to make contact with using other research methods.

There is an associated challenge of anonymity. There can be types of in-depth interview that make it particularly challenging to protect the identities of participants, such as interviewing within a small community, or multiple members of the same household. The challenge to ensure anonymity in such contexts is even more important and difficult when the topic of research is of a sensitive nature or participants are vulnerable.

Increasingly, researchers are collaborating in large-scale interview-based studies and integrating interviews into broader mixed-methods designs. At the same time, interviews can be seen as an old-fashioned (and perhaps outdated) mode of data collection. We review these debates and discussions and point to innovations in interview-based studies. These include the shift from face-to-face interviews to the use of online platforms, as well as integrating and adapting interviews towards more inclusive methodologies.

Collaborating and mixing

Qualitative researchers have long worked alone 66 . Increasingly, however, researchers are collaborating with others for reasons such as efficiency, institutional incentives (for example, funding for collaborative research) and a desire to pool expertise (for example, studying similar phenomena in different contexts 67 or via different methods). Collaboration can occur across disciplines and methods, cases and contexts and between industry/business, practitioners and researchers. In many settings and contexts, collaboration has become an imperative 68 .

Cheek notes how collaboration provides both advantages and disadvantages 68 . For example, collaboration can be advantageous, saving time and building on the divergent knowledge, skills and resources of different researchers. Scholars with different theoretical or case-based knowledge (or contacts) can work together to build research that is comparative and/or more than the sum of its parts. But such endeavours also carry with them practical and political challenges in terms of how resources might actually be pooled, shared or accounted for. When undertaking such projects, as Morse notes, it is worth thinking about the nature of the collaboration and being explicit about such a choice, its advantages and its disadvantages 66 .

A further tension, but also a motivation for collaboration, stems from integrating interviews as a method in a mixed-methods project, whether with other qualitative researchers (to combine with, for example, focus groups, document analysis or ethnography) or with quantitative researchers (to combine with, for example, surveys, social media analysis or big data analysis). Cheek and Morse both note the pitfalls of collaboration with quantitative researchers: that quality of research may be sacrificed, qualitative interpretations watered down or not taken seriously, or tensions experienced over the pace and different assumptions that come with different methods and approaches of research 66 , 68 .

At the same time, there can be real benefits of such mixed-methods collaboration, such as reaching different and more diverse audiences or testing assumptions and theories between research components in the same project (for example, testing insights from prior quantitative research via interviews, or vice versa), as long as the skillsets of collaborators are seen as equally beneficial to the project. Cheek provides a set of questions that, as a starting point, can be useful for guiding collaboration, whether mixed methods or otherwise. First, Cheek advises asking all collaborators about their assumptions and understandings concerning collaboration. Second, Cheek recommends discussing what each perspective highlights and focuses on (and conversely ignores or sidelines) 68 .

A different way to engage with the idea of collaboration and mixed methods research is by fostering greater collaboration between researchers in the Global South and Global North, thus reversing trends of researchers from the Global North extracting knowledge from the Global South 69 . Such forms of collaboration also align with interview innovations, discussed below, that seek to transform traditional interview approaches into more participatory and inclusive (as part of participatory methodologies).

Digital innovations and challenges

The ongoing COVID-19 pandemic has centred the question of technology within interview-based fieldwork. Although conducting synchronous oral interviews online — for example, via Zoom, Skype or other such platforms — has been a method used by a small constituency of researchers for many years, it became (and remains) a necessity for many researchers wanting to continue or start interview-based projects while COVID-19 prevents face-to-face data collection.

In the past, online interviews were often framed as an inferior form of data collection for not providing the kinds of (often necessary) insights and forms of immersion face-to-face interviews allow 70 , 71 . Online interviews do tend to be more decontextualized than interviews conducted face-to-face 72 . For example, it is harder to recognize, engage with and respond to non-verbal cues 71 . At the same time, they broaden participation to those who might not have been able to access or travel to sites where interviews would have been conducted otherwise, for example people with disabilities. Online interviews also offer more flexibility in terms of scheduling and time requirements. For example, they provide more flexibility around precarious employment or caring responsibilities without having to travel and be away from home. In addition, online interviews might also reduce discomfort between researchers and participants, compared with face-to-face interviews, enabling more discussion of sensitive material 71 . They can also provide participants with more control, enabling them to turn on and off the microphone and video as they choose, for example, to provide more time to reflect and disconnect if they so wish 72 .

That said, online interviews can also introduce new biases based on access to technology 72 . For example, in the Global South, there are often urban/rural and gender gaps between who has access to mobile phones and who does not, meaning that some population groups might be overlooked unless researchers sample mindfully 71 . There are also important ethical considerations when deciding between online and face-to-face interviews. Online interviews might seem to imply lower ethical risks than face-to-face interviews (for example, they lower the chances of identification of participants or researchers), but they also offer more barriers to building trust between researchers and participants 72 . Interacting only online with participants might not provide the information needed to assess risk, for example, participants’ access to a private space to speak 71 . Just because online interviews might be more likely to be conducted in private spaces does not mean that private spaces are safe, for example, for victims of domestic violence. Finally, online interviews prompt further questions about decolonizing research and engaging with participants if research is conducted from afar 72 , such as how to include participants meaningfully and challenge dominant assumptions while doing so remotely.

A further digital innovation, modulating how researchers conduct interviews and the kinds of data collected and analysed, stems from the use and integration of (new) technology, such as WhatsApp text or voice notes to conduct synchronous or asynchronous oral or written interviews 73 . Such methods can provide more privacy, comfort and control to participants and make recruitment easier, allowing participants to share what they want when they want to, using technology that already forms a part of their daily lives, especially for young people 74 , 75 . Such technology is also emerging in other qualitative methods, such as focus groups, with similar arguments around greater inclusivity versus traditional offline modes. Here, the digital challenge might be higher for researchers than for participants if they are less used to such technology 75 . And while there might be concerns about the richness, depth and quality of written messages as a form of interview data, Gibson reports that the reams of transcripts that resulted from a study using written messaging were dense with meaning to be analysed 75 .

Like with online and face-to-face interviews, it is important also to consider the ethical questions and challenges of using such technology, from gaining consent to ensuring participant safety and attending to their distress, without cues, like crying, that might be more obvious in a face-to-face setting 75 , 76 . Attention to the platform used for such interviews is also important and researchers should be attuned to the local and national context. For example, in China, many platforms are neither legal nor available 76 . There, more popular platforms — like WeChat — can be highly monitored by the government, posing potential risks to participants depending on the topic of the interview. Ultimately, researchers should consider trade-offs between online and offline interview modalities, being attentive to the social context and power dynamics involved.

The next 5–10 years

Continuing to integrate (ethically) this technology will be among the major persisting developments in interview-based research, whether to offer more flexibility to researchers or participants, or to diversify who can participate and on what terms.

Pushing the idea of inclusion even further is the potential for integrating interview-based studies within participatory methods, which are also innovating via integrating technology. There is no hard and fast line between researchers using in-depth interviews and participatory methods; many who employ participatory methods will use interviews at the beginning, middle or end phases of a research project to capture insights, perspectives and reflections from participants 77 , 78 . Participatory methods emphasize the need to resist existing power and knowledge structures. They broaden who has the right and ability to contribute to academic knowledge by including and incorporating participants not only as subjects of data collection, but as crucial voices in research design and data analysis 77 . Participatory methods also seek to facilitate local change and to produce research materials, whether for academic or non-academic audiences, including films and documentaries, in collaboration with participants.

In responding to the challenges of COVID-19, capturing the fraught situation wrought by the pandemic and the momentum to integrate technology, participatory researchers have sought to continue data collection from afar. For example, Marzi has adapted an existing project to co-produce participatory videos, via participants’ smartphones in Medellin, Colombia, alongside regular check-in conversations/meetings/interviews with participants 79 . Integrating participatory methods into interview studies offers a route by which researchers can respond to the challenge of diversifying knowledge, challenging assumptions and power hierarchies and creating more inclusive and collaborative partnerships between participants and researchers in the Global North and South.

Advantages of Interviews in Research

Interviews are an essential part of the research process, whether used to gather data for a news article, explore a specific research topic, or understand the intricacies of someone's life story. Interviews provide unique insights into phenomena from the perspective of individuals, offering in-depth information that other methods for collecting primary data may not capture. In this article, we will go over the main advantages of interviews and examples showing why they are so important in qualitative research.

Whether it is a phone interview or a traditional in-person interview, the advantages of interviews lie in the richness of qualitative data they provide. Through in-person interviews, researchers gain access to firsthand experiences and personal perceptions of the phenomenon under study. This level of detail is difficult to achieve through other data collection methods like surveys , focus groups , or general literature reviews .

In-depth interviews allow researchers to dive deep into the information collected via interviewees' responses and body language. Unlike surveys, which may restrict responses to predetermined options, interviews encourage participants to elaborate on their thoughts, feelings, and experiences. This results in detailed data that can reveal new insights and spur the development of new theories.

Interviews can also give voice to populations that might otherwise remain unheard. For instance, the "man on the street" interviews, popularized in the 1930s by radio programs, are a classic example of interview methods used to capture the public's opinions. Today, these interview methods are still prevalent in journalism, particularly in news broadcasts and documentaries, to gauge public sentiment quickly.

In qualitative research, interviews hold great importance because they place the participant at the center of the research project, ensuring that their voice and perspectives are prioritized. Interviews are especially effective for capturing personal narratives, stories, and life histories. This makes them ideal for research focused on biography, identity, and personal development. Through interviews, researchers can document individual journeys, challenges, and transformations, providing a rich tapestry of human experience.

In qualitative research, interviews are a widely used method that provides deep, rich data that can uncover the complexities of human experience. Interviews allow researchers to explore issues that may not be fully understood or captured through other data collection methods such as surveys or focus groups. The interview process will enable researchers to thoroughly explore a participant’s feelings, thoughts, and experiences. Open-ended questions let participants express themselves freely, offering insights that might not emerge in other methods like surveys or focus groups. Open-ended questions enable participants to express themselves freely and let researchers to ask valuable follow-up questions that arise at the moment.

Participant-focused

Interviews place the participant at the center of the research process and give high importance to the participant's voice and perspective, which leads to more authentic and participant-driven research findings. This is particularly valuable in research that looks at marginalized or underrepresented groups.

Research interviews can be conducted in ways that are sensitive to the cultural and social contexts of participants. Researchers can tailor their questions to align with the participant's cultural background, language, and social norms, leading to qualitative data that is more reflective of the participant's lived reality.

The conversational nature of interviews enables participants to express their thoughts and experiences in their own words. This allows for the discovery of new themes or ideas that the researcher may not have anticipated. With in-person interviews, researchers can also attend to body language and other non-verbal communication that can give further information.

Flexible and personalized

The flexibility inherent in interviews is another advantage of this data collection method. Follow-up questions are vital for obtaining accurate and comprehensive research findings which can be completely missed in data collection methods using only multiple-choice questions. When the research interview is conducted in person, non-verbal cues such as body language, facial expressions, and tone of voice provide additional context and meaning to verbal responses. This is a significant advantage over methods like online interviews or phone interviews, where such cues may be absent or harder to interpret.

Personalization is also a crucial advantage of in-person interviews. Researchers can tailor the interview questions and adapt the interview process to accommodate the specific needs of the research topic. This is especially useful when dealing with complex or sensitive topics, where ethical considerations are paramount. Customization in interviews provides researchers with a unique approach to data collection. Whether using structured interviews, semi-structured interviews, or unstructured interviews , the method can be adapted to suit the research methods being employed. Customization also involves adapting to the interviewee's language, comfort levels, and other cultural sensitivities.

When conducted over time, interviews can provide longitudinal insights into how participants' views, experiences, or behaviours evolve. This is particularly valuable in research that seeks to understand changes over time, such as studies on personal growth, adaptation, or the impact of long-term interventions.

Potential for new theories

In qualitative research, interviews can be used to develop new theories or refine existing ones. By analyzing data collected from interviews, researchers can identify patterns, themes, and relationships that contribute to the development of theoretical frameworks . The open-ended nature of interview questions, coupled with the interviewer's possibility to adapt their questions according to the flow of the conversation, provides ample room for unanticipated ideas or insights to emerge.

Interviews are about obtaining detailed data and understanding how participants arrive at their answers. This focus on process allows researchers to comprehend how participants make sense of their experiences, how they construct meaning, and how they navigate complex issues. Such insights into cognitive and emotional processes are invaluable in qualitative research.

Dynamic interactions

Unlike other qualitative research methods, interviews allow for dynamic interaction between the interviewer and the participant. This interaction can lead to the co-construction of knowledge, where both parties contribute to shaping the data. This dynamic process can reveal insights that are more reflective of the participant's thoughts and feelings.

In qualitative research, interviews can be used alongside other methods such as focus groups, observations, or document analysis to triangulate insights. This helps to validate findings and ensures a more comprehensive understanding of the research question.

Ethical and confidential

Interviews allow researchers to approach sensitive topics ethically. Researchers can build trust with participants, ensure confidentiality, and provide support if difficult emotions or topics arise during the interview. This makes interviews particularly suitable for research on sensitive or traumatic experiences.

Interviews can uncover tacit knowledge—insights that participants may not even realize they possess or are difficult to articulate. Researchers can help participants express these deeply embedded insights through careful questioning and probing.

Interviews and their different methods of delivery also have advantages of their own. This section will introduce the most common types of interviews and their advantages.

Focus groups

Focus group interviews can be advantageous because of the non-verbal communication they offer such as body language and facial expressions that come from interacting in groups. Focus groups give information through the interaction between participants. They produce rich perspectives as participants comment and build upon each other's answers. Focus groups also provide a safe space for those who feel more at ease expressing themselves in a group setting.

Face-to-face interviews

In-person interviews are particularly advantageous in qualitative research because they offer an additional layer of information as the researcher can see non-verbal communication such as gestures, and body expressions. This provides insight into the participant's feelings and reactions to questions or themes. This presents a great advantage compared to methods that use verbal communication solely because it adds complexity to the answers and emotions are more transparent. Face-to-face interviews also offer a faster establishment of rapport and trust and interviewers can adapt the interviews based on verbal responses.

Telephone interviews

When it comes to bridging distances, telephone interviews are among the best. They bridge distance and provide direct communication, which can sometimes impede if a person is far away from the interviewer or if access to the internet is scarce. It can also provide a safe space for those who do not feel comfortable sharing information in person due to sensitive issues. They are also cost-effective and scheduling and

Email interviews

Asynchronous communication is one of the key advantages of email interviews. They are also low-pressure for introverted participants who rather not do an interview face-to-face. In a similar way to telephone interviews, email interviews bridge distances and help diversify the pool of participants. They are also useful when the language is different from the interviewer as the use of translators can open communication doors.

Here are some real cases where the advantages of interviews played a crucial role in the success of qualitative research:

Gender construction research

In Becoming a Gendered Body: Practices of Preschools (Martin, 1998), data was collected through direct observations and semi-structured in-person interviews. Over 50 hours of observation were conducted in five preschool classrooms, where Martin documented daily activities, interactions, and routines, paying close attention to how gendered behaviours were enacted and encouraged by both teachers and students. She observed how children were expected to sit, play, and move differently based on their gender, revealing the subtle ways in which gender norms were reinforced in early childhood education.

To complement these observations, Martin conducted semi-structured interviews with preschool teachers, exploring their perspectives on gender and the practices they used in the classroom. These interviews provided rich qualitative data on how teachers understood their role in promoting or challenging gender norms. By combining observational data with interviews, Martin was able to offer a comprehensive analysis of how gender is socially constructed and reinforced in preschool settings.

The 'Up Series' documentary films

The Up series is a groundbreaking British documentary film project that follows the lives of fourteen individuals from different social backgrounds in the United Kingdom, beginning in 1964 when they were seven years old. The series was conceived by Granada Television and initially directed by Paul Almond, with subsequent installments directed by Michael Apted, who continued the project until he died in 2021. The premise of the series is rooted in the idea that social class and circumstances could predict the future of these children, encapsulated in the Jesuit saying, "Give me a child until he is seven, and I will show you the man."

Every seven years, a new installment of the series has been released, documenting the participants' lives as they navigate various stages of life—childhood, adolescence, adulthood, and middle age.

In the Up Series, data collection was done through a longitudinal documentary approach, where in-depth, semi-structured in-person interviews were conducted with the same group of participants every seven years. The series also collects visual and behavioural data by video-documenting the participants in their everyday environments, providing insights into their social and economic conditions.

Challenges faced by women in career progression

In 2020, Goriss-Hunter and White conducted a study using asynchronous email interviews to investigate the career experiences of women at an Australian regional university. The researchers gathered data from 21 participants, including both academic and professional staff, by asking open-ended questions about career barriers and enablers. The results indicated that participants faced significant challenges, particularly due to the COVID-19 pandemic. Themes such as limited access to professional development, gendered workplace expectations, and work-life balance struggles were prominent. The flexibility of email interviews allowed participants to respond in their own time, facilitating in-depth reflections (Goriss-Hunter & White, 2020).

Interviews are a valuable data collection method in qualitative research due to their ability to provide deep, rich data. They allow for exploring complex issues, offer a participant-centred approach, and are sensitive to cultural and social contexts. Interviews facilitate the development of new theories and emphasize the process through which participants make sense of their experiences. They are also particularly effective for capturing personal narratives and offer flexibility in questioning, making them adaptable to the flow of conversation.

Interviews also allow for the triangulation of data when used alongside other methods and can provide longitudinal insights when conducted over time. They enable researchers to approach sensitive topics ethically, ensuring confidentiality and support for participants. Additionally, interviews can uncover tacit knowledge—insights that are deeply embedded in participants' experiences but not easily articulated. Overall, interviews are a versatile and powerful method for understanding complex human experiences and social phenomena.

• InterViews by Steinar Kvale  Interviewing is an essential tool in qualitative research and this introduction to interviewing outlines both the theoretical underpinnings and the practical aspects of the process. After examining the role of the interview in the research process, Steinar Kvale considers some of the key philosophical issues relating to interviewing: the interview as conversation, hermeneutics, phenomenology, concerns about ethics as well as validity, and postmodernism. Having established this framework, the author then analyzes the seven stages of the interview process - from designing a study to writing it up.

13.1 Interview research: What is it and when should it be used?

Learning objectives.

• Define interviews from the social scientific perspective
• Identify when it is appropriate to employ interviews as a data-collection strategy

Knowing how to create and conduct a good interview is an essential skill. Interviews are used by market researchers to learn how to sell their products. Journalists use interviews to get information from a host of people, from VIPs to random people on the street. Police use interviews to investigate crimes. It seems everyone who’s anyone knows how to conduct an interview.

In social science,  interviews are a method of data collection that involves two or more people exchanging information through a series of questions and answers. The questions are designed by a researcher to elicit information from interview participants on a specific topic or set of topics. These topics are informed by the author’s research questions. Interviews typically involve an in-person meeting between two people (an interviewer and an interviewee), but interviews need not be limited to two people, nor must they occur in-person.

You may be wondering when you should choose interviews as your data collection method. Interviews are an excellent way to gather detailed information. They also have an advantage over surveys, as they can be adapted as you learn more information. Recall that survey data collection methods do not allow researchers to change the questions that are administered, even if a participant’s response sparks some follow-up question in your mind. All participants must be asked the same questions in the same manner. The questions you decided to put on your survey during the design stage determine what data you get. In an interview, however, you can follow up on new and unexpected topics that emerge during the conversation. Trusting in emergence and learning from your participants are hallmarks of qualitative research. In this way, interviews are a useful method to employ when you want to know the story behind the responses you might receive in a written survey.

Interviews are also useful when your topic is rather complex, requires lengthy explanation, or needs a dialogue between two people to thoroughly investigate. Additionally, interviews may be the best method to utilize if your study involves describing the process by which a phenomenon occurs, like how a person makes a decision. For example, you could use interviews to gather data about how people reach the decision not to have children and how others in their lives have responded to that decision. To understand these processes, you would need to exchange dialogue with respondents. When they begin to share their story with you, new questions that hadn’t occurred to you in prior interviews will arise because each person’s story is unique. Further, closed-ended survey questions would not be as effective in capturing the complex process of choosing not to have children.

In sum, interview research is especially useful when the following are true:

• You wish to gather very detailed information
• You anticipate wanting to ask respondents follow-up questions based on their responses
• You plan to ask questions that require lengthy explanation
• You are studying a complex or potentially confusing topic to respondents
• You are studying processes, such as how people make decisions

Key Takeaways

• Understanding how to design and conduct interview research is a useful skill to have.
• In a social scientific interview, two or more people exchange information through a series of questions and answers.
• Interview research is often used when detailed information is required and when a researcher wishes to examine processes.

Learning outcomes

Upon completion of this chapter, you should be able to:

• Understand when to use interviews in qualitative research.
• Develop interview questions for an interview guide.
• Understand how to conduct an interview.

What are interviews?

An interviewing method is the most commonly used data collection technique in qualitative research. 1 The purpose of an interview is to explore the experiences, understandings, opinions and motivations of research participants. 2 Interviews are conducted one-on-one with the researcher and the participant. Interviews are most appropriate when seeking to understand a participant’s subjective view of an experience and are also considered suitable for the exploration of sensitive topics.

What are the different types of interviews?

There are four main types of interviews:

• Key stakeholder: A key stakeholder interview aims to explore one issue in detail with a person of interest or importance concerning the research topic. 3 Key stakeholder interviews seek the views of experts on some cultural, political or health aspects of the community, beyond their personal beliefs or actions. An example of a key stakeholder is the Chief Health Officer of Victoria (Australia’s second-most populous state) who oversaw the world’s longest lockdowns in response to the COVID-19 pandemic.
• Dyad: A dyad interview aims to explore one issue in a level of detail with a dyad (two people). This form of interviewing is used when one participant of the dyad may need some support or is not wholly able to articulate themselves (e.g. people with cognitive impairment, or children). Independence is acknowledged and the interview is analysed as a unit. 4
• Narrative: A narrative interview helps individuals tell their stories, and prioritises their own perspectives and experiences using the language that they prefer. 5 This type of interview has been widely used in social research but is gaining prominence in health research to better understand person-centred care, for example, negotiating exercise and food abstinence whilst living with Type 2 diabetes. 6,7
• Life history: A life history interview allows the researcher to explore a person’s individual and subjective experiences within a history of the time framework. 8 Life history interviews challenge the researcher to understand how people’s current attitudes, behaviours and choices are influenced by previous experiences or trauma. Life history interviews have been conducted with Holocaust survivors 9 and youth who have been forcibly recruited to war. 10

Table 13.4 provides a summary of four studies, each adopting one of these types of interviews.

Interviewing techniques

There are two main interview techniques:

• Semi-structured: Semi-structured interviewing aims to explore a few issues in moderate detail, to expand the researcher’s knowledge at some level. 11 Semi-structured interviews give the researcher the advantage of remaining reasonably objective while enabling participants to share their perspectives and opinions. The researcher should create an interview guide with targeted open questions to direct the interview. As examples, semi-structured interviews have been used to extend knowledge of why women might gain excess weight during pregnancy, 12 and to update guidelines for statin uptake. 13
• In-depth: In-depth interviewing aims to explore a person’s subjective experiences and feelings about a particular topic. 14 In-depth interviews are often used to explore emotive (e.g. end-of-life care) 15 and complex (e.g. adolescent pregnancy) topics. 16 The researcher should create an interview guide with selected open questions to ask of the participant, but the participant should guide the direction of the interview more than in a semi-structured setting. In-depth interviews value participants’ lived experiences and are frequently used in phenomenology studies (as described in Chapter 6) .

When to use the different types of interview s

The type of interview a researcher uses should be determined by the study design, the research aims and objectives, and participant demographics. For example, if conducting a descriptive study, semi-structured interviews may be the best method of data collection. As explained in Chapter 5 , descriptive studies seek to describe phenomena, rather than to explain or interpret the data. A semi-structured interview, which seeks to expand upon some level of existing knowledge, will likely best facilitate this.

Similarly, if conducting a phenomenological study, in-depth interviews may be the best method of data collection. As described in Chapter 6 , the key concept of phenomenology is the individual. The emphasis is on the lived experience of that individual and the person’s sense-making of those experiences. Therefore, an in-depth interview is likely best placed to elicit that rich data.

While some interview types are better suited to certain study designs, there are no restrictions on the type of interview that may be used. For example, semi-structured interviews provide an excellent accompaniment to trial participation (see Chapter 11 about mixed methods), and key stakeholder interviews, as part of an action research study, can be used to define priorities, barriers and enablers to implementation.

How do I write my interview questions?

An interview aims to explore the experiences, understandings, opinions and motivations of research participants. The general rule is that the interviewee should speak for 80 per cent of the interview, and the interviewer should only be asking questions and clarifying responses, for about 20 per cent of the interview. This percentage may differ depending on the interview type; for example, a semi-structured interview involves the researcher asking more questions than in an in-depth interview. Still, to facilitate free-flowing responses, it is important to use open-ended language to encourage participants to be expansive in their responses. Examples of open-ended terms include questions that start with ‘who’, ‘how’ and ‘where’.

The researcher should avoid closed-ended questions that can be answered with yes or no, and limit conversation. For example, asking a participant ‘Did you have this experience?’ can elicit a simple ‘yes’, whereas asking them to ‘Describe your experience’, will likely encourage a narrative response. Table 13.1 provides examples of terminology to include and avoid in developing interview questions.

Table 13.1. Interview question formats to use and avoid

How long should my interview be.

There is no rule about how long an interview should take. Different types of interviews will likely run for different periods of time, but this also depends on the research question/s and the type of participant. For example, given that a semi-structured interview is seeking to expand on some previous knowledge, the interview may need no longer than 30 minutes, or up to one hour. An in-depth interview seeks to explore a topic in a greater level of detail and therefore, at a minimum, would be expected to last an hour. A dyad interview may be as short as 15 minutes (e.g. if the dyad is a person with dementia and a family member or caregiver) or longer, depending on the pairing.

Designing your interview guide

To figure out what questions to ask in an interview guide, the researcher may consult the literature, speak to experts (including people with lived experience) about the research and draw on their current knowledge. The topics and questions should be mapped to the research question/s, and the interview guide should be developed well in advance of commencing data collection. This enables time and opportunity to pilot-test the interview guide. The pilot interview provides an opportunity to explore the language and clarity of questions, the order and flow of the guide and to determine whether the instructions are clear to participants both before and after the interview. It can be beneficial to pilot-test the interview guide with someone who is not familiar with the research topic, to make sure that the language used is easily understood (and will be by participants, too). The study design should be used to determine the number of questions asked and the duration of the interview should guide the extent of the interview guide. The participant type may also determine the extent of the interview guide; for example, clinicians tend to be time-poor and therefore shorter, focused interviews are optimal. An interview guide is also likely to be shorter for a descriptive study than a phenomenological or ethnographic study, given the level of detail required. Chapter 5 outlined a descriptive study in which participants who had undergone percutaneous coronary intervention were interviewed. The interview guide consisted of four main questions and subsequent probing questions, linked to the research questions (see Table 13.2). 17

Table 13.2. Interview guide for a descriptive study

Table 13.3 is an example of a larger and more detailed interview guide, designed for the qualitative component of a mixed-methods study aiming to examine the work and financial effects of living with arthritis as a younger person. The questions are mapped to the World Health Organization’s International Classification of Functioning, Disability, and Health, which measures health and disability at individual and population levels. 18

Table 13.3. Detailed interview guide

It is important to create an interview guide, for the following reasons:

• The researcher should be familiar with their research questions.
• Using an interview guide will enable the incorporation of feedback from the piloting process.
• It is difficult to predict how participants will respond to interview questions. They may answer in a way that is anticipated or they may provide unanticipated insights that warrant follow-up. An interview guide (a physical or digital copy) enables the researcher to note these answers and follow-up with appropriate inquiry.
• Participants will likely have provided heterogeneous answers to certain questions. The interview guide enables the researcher to note similarities and differences across various interviews, which may be important in data analysis.
• Even experienced qualitative researchers get nervous before an interview! The interview guide provides a safety net if the researcher forgets their questions or needs to anticipate the next question.

Setting up the interview

In the past, most interviews were conducted in person or by telephone. Emerging technologies promote easier access to research participation (e.g. by people living in rural or remote communities, or for people with mobility limitations). Even in metropolitan settings, many interviews are now conducted electronically (e.g. using videoconferencing platforms). Regardless of your interview setting, it is essential that the interview environment is comfortable for the participant. This process can begin as soon as potential participants express interest in your research. Following are some tips from the literature and our own experiences of leading interviews:

• Answer questions and set clear expectations . Participating in research is not an everyday task. People do not necessarily know what to expect during a research interview, and this can be daunting. Give people as much information as possible, answer their questions about the research and set clear expectations about what the interview will entail and how long it is expected to last. Let them know that the interview will be recorded for transcription and analysis purposes. Consider sending the interview questions a few days before the interview. This gives people time and space to reflect on their experiences, consider their responses to questions and to provide informed consent for their participation.
• Consider your setting . If conducting the interview in person, consider the location and room in which the interview will be held. For example, if in a participant’s home, be mindful of their private space. Ask if you should remove your shoes before entering their home. If they offer refreshments (which in our experience many participants do), accept it with gratitude if possible. These considerations apply beyond the participant’s home; if using a room in an office setting, consider privacy and confidentiality, accessibility and potential for disruption. Consider the temperature as well as the furniture in the room, who may be able to overhear conversations and who may walk past. Similarly, if interviewing by phone or online, take time to assess the space, and if in a house or office that is not quiet or private, use headphones as needed.
• Build rapport. The research topic may be important to participants from a professional perspective, or they may have deep emotional connections to the topic of interest. Regardless of the nature of the interview, it is important to remember that participants are being asked to open up to an interviewer who is likely to be a stranger. Spend some time with participants before the interview, to make sure that they are comfortable. Engage in some general conversation, and ask if they have any questions before you start. Remember that it is not a normal part of someone’s day to participate in research. Make it an enjoyable and/or meaningful experience for them, and it will enhance the data that you collect.
• Let participants guide you. Oftentimes, the ways in which researchers and participants describe the same phenomena are different. In the interview, reflect the participant’s language. Make sure they feel heard and that they are willing and comfortable to speak openly about their experiences. For example, our research involves talking to older adults about their experience of falls. We noticed early in this research that participants did not use the word ‘fall’ but would rather use terms such as ‘trip’, ‘went over’ and ‘stumbled’. As interviewers we adopted the participant’s language into our questions.
• Listen consistently and express interest. An interview is more complex than a simple question-and-answer format. The best interview data comes from participants feeling comfortable and confident to share their stories. By the time you are completing the 20th interview, it can be difficult to maintain the same level of concentration as with the first interview. Try to stay engaged: nod along with your participants, maintain eye contact, murmur in agreement and sympathise where warranted.
• The interviewer is both the data collector and the data collection instrument. The data received is only as good as the questions asked. In qualitative research, the researcher influences how participants answer questions. It is important to remain reflexive and aware of how your language, body language and attitude might influence the interview. Being rested and prepared will enhance the quality of the questions asked and hence the data collected.
• Avoid excessive use of ‘why’. It can be challenging for participants to recall why they felt a certain way or acted in a particular manner. Try to avoid asking ‘why’ questions too often, and instead adopt some of the open language described earlier in the chapter.

After your interview

When you have completed your interview, thank the participant and let them know they can contact you if they have any questions or follow-up information they would like to provide. If the interview has covered sensitive topics or the participant has become distressed throughout the interview, make sure that appropriate referrals and follow-up are provided (see section 6).

Download the recording from your device and make sure it is saved in a secure location that can only be accessed by people on the approved research team (see Chapters 35 and 36).

It is important to know what to do immediately after each interview is completed. Interviews should be transcribed – that is, reproduced verbatim for data analysis. Transcribing data is an important step in the process of analysis, but it is very time-consuming; transcribing a 60-minute interview can take up to 8 hours. Data analysis is discussed in Section 4.

Table 13.4. Examples of the four types of interviews

Interviews are the most common data collection technique in qualitative research. There are four main types of interviews; the one you choose will depend on your research question, aims and objectives. It is important to formulate open-ended interview questions that are understandable and easy for participants to answer. Key considerations in setting up the interview will enhance the quality of the data obtained and the experience of the interview for the participant and the researcher.

Background: Interviews are among the most familiar strategies for collecting qualitative data. The different qualitative interviewing strategies in common use emerged from diverse disciplinary perspectives resulting in a wide variation among interviewing approaches. Unlike the highly structured survey interviews and questionnaires used in epidemiology and most health services research, we examine less structured interview strategies in which the person interviewed is more a participant in meaning making than a conduit from which information is retrieved.

Purpose: In this article we briefly review the more common qualitative interview methods and then focus on the widely used individual face-to-face in-depth interview, which seeks to foster learning about individual experiences and perspectives on a given set of issues. We discuss methods for conducting in-depth interviews and consider relevant ethical issues with particular regard to the rights and protection of the participants.

Types of Interviews in Research and Methods

There are more types of interviews than most people think. An interview is generally a qualitative research technique that involves asking open-ended questions to converse with respondents and collect elicit data about a subject.

The interviewer, in most cases, is the subject matter expert who intends to understand respondent opinions in a well-planned and executed series of star questions and answers . 

Interviews are similar to focus groups and surveys for garnering information from the target market but are entirely different in their operation – focus groups are restricted to a small group of 6-10 individuals, whereas surveys are quantitative.

Interviews are conducted with a sample from a population, and the key characteristic they exhibit is their conversational tone.

What is An Interview?

An interview is a way to get information from a person by asking questions and hearing their answers.

An interview is a question-and-answer session where one person asks questions, and the other person answers those questions. It can be a one-on-one, two-way conversation, or there can be more than one interviewer and more than one participant.

The interview is the most important part of the whole selection bias process. It is used to decide if a person should be interviewed further, hired, or taken out of consideration. It is the main way to learn more about applicants and the basis for judging their job-related knowledge, research skills , and abilities.

Fundamental Types of Interviews in Research

A researcher has to conduct interviews with a group of participants at a juncture in the research where information can only be obtained by meeting and personally connecting with a section of their target audience. Interviews offer the researchers a platform to prompt their participants and obtain inputs in the desired detail. There are three fundamental types of interviews in research:

1. Structured Interviews:

Structured interviews are defined as research tools that could be more flexible in their operations are allow more or no scope of prompting the participants to obtain and analyze results. It is thus also known as a standardized interview and is significantly quantitative in its approach. 

Questions in this interview are pre-decided according to the required detail of information. This can be used in a focus group interview and an in-person interview.

These interviews are excessively used in survey research with the intention of maintaining uniformity throughout all the interview sessions.

LEARN ABOUT: Research Process Steps

They can be closed-ended and open-ended – according to the type of target population. Closed-ended questions can be included to understand user preferences from a collection of answer options. In contrast, open-ended ones can be included to gain details about a particular section in the interview.

Example of a structured interview question:

Here’s an example of a structured question for a job interview for a customer service job:

• Can you talk about what it was like to work in customer service?
• How do you deal with an angry or upset customer?
• How do you ensure that the information you give customers is correct?
• Tell us about when you went out of your way to help a customer.
• How do you handle a lot of customers or tasks at once?
• Can you talk about how you’ve used software or tools for customer service?
• How do you set priorities and use your time well while giving good customer service?
• Can you tell us about when you had to get a customer to calm down?
• How do you deal with a customer who wants something that goes against your company’s rules?
• Tell me about a time when you had to deal with a hard customer or coworker.

Advantages of structured interviews:

• It focuses on the accuracy of different responses, due to which extremely organized data can be collected. Different respondents have different types of answers to the same structure of questions – answers obtained can be collectively analyzed.
• They can be used to get in touch with a large sample of the target population.
• The interview procedure is made easy due to the standardization offered by it.
• Replication across multiple samples becomes easy due to the same structure of the interview.
• As the scope of detail is already considered while designing the interview questions, better information can be obtained. The researcher can analyze the research problem comprehensively by asking accurate research questions .
• Since the structure of the interview is fixed, it often generates reliable results and is quick to execute.
• The relationship between the researcher and the respondent is not formal, due to which the researcher can clearly understand the margin of error in case the respondent either degree to be a part of the survey or is just not interested in providing the right information.

Disadvantages of structured interviews:

• The limited scope of assessment of obtained results.
• The accuracy of information overpowers the detail of information.
• Respondents are forced to select from the provided answer options.
• The researcher is expected to always adhere to the list of decided questions, irrespective of how interesting the conversation is turning out to be with the participants.
• A significant amount of time is required for a structured interview.

2. Semi-Structured Types of Interviews:

Semi-structured interviews offer a considerable amount of leeway to the researcher to probe the respondents, along with maintaining a basic interview structure. Even if it is a guided conversation between researchers and interviewees – appreciable flexibility is offered to the researchers. A researcher can be assured that multiple interview rounds will not be required in the presence of structure in this type of research interview.

Keeping the structure in mind, the researcher can follow any idea or take creative advantage of the entire interview. Additional respondent probing is always necessary to garner information for a research study. The best application of semi-structured interviews is when the researcher doesn’t have time to conduct research and requires detailed information about the topic.

Example of a semi-structured interview question:

Here’s an example of a semi-structured marketing job interviews question:

• Can you tell us about the marketing work you’ve done?
• What do you think are the most important parts of a marketing campaign that works?
• Tell me about a campaign you worked on that you’re very proud of.
• How do you do research on the market and look at data to help you make marketing decisions?
• Can you tell us about a time when you had to change your marketing plan because of something that didn’t go as planned?
• How do you figure out if a marketing campaign worked?
• Can you talk about how you’ve used social media to market?
• How do you ensure your marketing message gets through to the people you want to hear it?
• Can you tell us about a time when you had to run a marketing campaign on a small budget?
• How do you keep up with changes and trends in marketing?

Advantages of semi-structured interviews:

• Questions from semi-structured interview questions are prepared before the scheduled interview, giving the researcher time to prepare and analyze the questions.
• It is flexible to an extent while maintaining the research guidelines.
• Unlike a structured interview, researchers can express the interview questions in the preferred format.
• Reliable qualitative data can be collected via these interviews.
• The flexible structure of the interview.

Disadvantages of semi-structured interviews:

• Participants may question the reliability factor of these interviews due to the flexibility offered.
• Comparing two different answers becomes difficult as the guideline for conducting interviews is not entirely followed. No two questions will have the exact same structure, and the result will be an inability to compare are infer results.

3. Unstructured Interviews:

Also called in-depth interviews , unstructured interviews are usually described as conversations held with a purpose in mind – to gather data about the research study. These interviews have the least number of questions as they lean more towards a normal conversation but with an underlying subject.

The main objective of most researchers using unstructured interviews is to build a bond with the respondents, due to which there is a high chance that the respondents will be 100% truthful with their answers. There are no guidelines for the researchers to follow. So they can approach the participants ethically to gain as much information as possible about their research topic.

Since there are no guidelines for these interviews, a researcher is expected to keep their approach in check so that the respondents do not sway away from the main research motive. 

For a researcher to obtain the desired outcome, he/she must keep the following factors in mind:

• The intent of the interview.
• The interview should primarily take into consideration the participant’s interests and skills.
• All the conversations should be conducted within the permissible limits of research, and the researcher should try and stick by these limits.
• The researcher’s skills and knowledge should match the interview’s purpose.
• Researchers should understand the dos and don’ts of it.

Example of an unstructured interview question:

Here’s an example of a question asked in an unstructured interview:

• Can you tell me about when you had to deal with something hard and how you did it?
• What are some of the things you’re most proud of, and what did you learn from them?
• How do you deal with ambiguity or not knowing what to do at work?
• Can you describe how you lead and how you get your team going?
• Tell me about a time when you had to take a chance and how it turned out.
• What do you think are the most important qualities for success in this role?
• How do you deal with setbacks or failures, and what do you learn from them?
• Can you tell me about a time when you had to solve a problem by thinking outside the box?
• What do you think makes you different from the other people who want this job?
• Can you tell me about a time when you had to make a hard choice and how you made that choice?

Advantages of Unstructured Interviews:

• Due to this type of interview’s informal nature, it becomes extremely easy for researchers to try and develop a friendly rapport with the participants. This leads to gaining insights in extreme detail without much conscious effort.
• The participants can clarify all their doubts about the questions, and the researcher can take each opportunity to explain his/her intention for better answers.
• There are no questions that the researcher has to abide by, and this usually increases the flexibility of the entire research process.

Disadvantages of Unstructured Interviews:

• Researchers take time to execute these interviews because there is no structure to the interview process.
• The absence of a standardized set of questions and guidelines indicates that its reliability of it is questionable.
• The ethics involved in these interviews are often considered borderline upsetting.

Other Types of Interviews

Besides the 3 basic interview types, we have already mentioned there are more. Here are some other interview types that are commonly used in a job interview:

Behavioral Interview

During this type of interview, candidates are asked to give specific examples of how they have acted in the past. The idea behind this kind of interview is that what someone did in the past can be a sign of how they will act in the future. And by this interview, the company can also understand the interviewee’s behavior through body language.

Panel Interview

During a panel interview, three or more interviewers usually ask questions and evaluate the candidate’s answers as a group. This is a good way to get a full picture of a candidate’s skills and suitability for the job.

Group Types of Interviews

Multiple people are interviewed at the same time in group interviews. This form of interview often focus groups that are utilized on entry-level positions or employment in customer service to examine how well candidates get along with others and function as a team.

Case Interview

During a case interview, candidates are given a business problem or scenario and asked to think about how to solve it. In the consulting and finance fields, this kind of interview is common.

Technical Interview

A candidate’s technical skills and knowledge are tested during a technical interview, usually in fields like engineering or software development. Most of the time, candidates are asked to solve problems or complete technical tasks.

Stress Interview

During a stress interview, candidates are put under pressure or asked difficult or confrontational questions on purpose to see how they react in stressful situations. This kind of interview is used to see how well a candidate can deal with stress and hard situations.

Methods of Research Interviews:

There are four methods to conduct research interviews, each of which is peculiar in its application and can be used according to the research study requirement.

Personal Interviews:

Personal interviews are one of the most used types of interviews, where the questions are asked personally directly to the respondent as a form of an individual interview. One of the many in-person interviews is a lunch interview, which is frequently better suited for casual inquiries and discussions.

For this, a researcher can have a guide to online surveys to take note of the answers. A researcher can design his/her survey in such a way that they take notes of the comments or points of view that stands out from the interviewee. It can be a one-on-one interview as well. 

• Higher response rate.
• When the interviewees and respondents are face-to-face, there is a way to adapt the questions if this is not understood.
• More complete answers can be obtained if there is doubt on both sides or a remarkable piece of information is detected.
• The researcher has an opportunity to detect and analyze the interviewee’s body language at the time of asking the questions and taking notes about it.

Disadvantages:

• They are time-consuming and extremely expensive.
• They can generate distrust on the part of the interviewee since they may be self-conscious and not answer truthfully.
• Contacting the interviewees can be a real headache, either scheduling an appointment in workplaces or going from house to house and not finding anyone.
• Therefore, many interviews are conducted in public places like shopping centers or parks. Even consumer studies take advantage of these sites to conduct interviews or surveys and give incentives, gifts, and coupons. In short, There are great opportunities for online research in shopping centers.
• Among the advantages of conducting such types of interviews is that the respondents will have more fresh information if the interview is conducted in the context and with the appropriate stimuli so that researchers can have data from their experience at the scene of the events immediately and first hand. The interviewer can use an online survey through a mobile device that will undoubtedly facilitate the entire process.

Telephonic Type of Interviews:

Phonic interviews are widely used and easily combined with online surveys to conduct research effectively.

Advantages:

• To find the interviewees, it is enough to have their phone numbers on hand.
• They are usually lower cost.
• The information is collected quickly.
• Having a personal contact can also clarify doubts or give more details of the questions.
• Many times researchers observe that people do not answer phone calls because it is an unknown number for the respondent or simply already changed their place of residence and they cannot locate it, which causes a bias in the interview.
• Researchers also face that they simply do not want to answer and resort to pretexts such as they are busy to answer, they are sick, they do not have the authority to answer the questions asked, they have no interest in answering, or they are afraid of putting their security at risk.
• One of the aspects that should be taken care of in these types of interviews is the kindness with which the interviewers address the respondents in order to get them to cooperate more easily with their answers. Good communication is vital for the generation of better answers.

Email or Web Page Types of Interviews:

Online research is growing more and more because consumers are migrating to a more virtual world, and it is best for each researcher to adapt to this change.

The increase in people with Internet access has made it popular that interviews via email or web page stand out among the types of interviews most used today. For this nothing better than an online survey.

More and more consumers are turning to online shopping, which is why they are a great niche to be able to carry out an interview that will generate information for the correct decision-making.

Advantages of email surveys:

• Speed in obtaining data
• The respondents respond according to their time, when they want, and where they decide.
• Online surveys can be mixed with other research methods or using some of the previous interview models. They are tools that can perfectly complement and pay for the project.
• A researcher can use a variety of questions and logic to create graphs and reports immediately.

Disadvantages of email survey:

• Low response rates
• Limited access to certain populations
• Potential for spam filters
• Lack of personal touch

What to Avoid in Different Types of Interviews

Try not to do any of the following things when you’re in an interview:

• Don’t blame your previous managers, coworkers, or companies. This will make a bad impression on the interviewer and show that you are not accountable.
• Do not go to the interview without knowing anything about the company you are interviewing for. Interviewers will think you don’t care about learning about the company if you don’t know anything.
• Don’t fidget with things because that shows you lack self-confidence and focus.
• Stop checking the time because it shows that you have something more important to do and that you don’t give the interview much importance.

Related Questions of Interviews

After the interview is over, you might also get a chance to ask some questions. You should make the most of this chance to learn useful things from the interviewer. Based on what you’ve learned, you can then decide if the company and the job are a good fit for you. You can ask the interviewer questions about the company or about the job role.

Here are some common but important questions to ask in an interview:

• What do you anticipate from team members in this role?
• What does a typical day look like for an employee in this role?
• What qualities are essential for success in this position?
• How is success measured for this position?
• How does this job profile relate to the organization’s overarching objectives?
• What are your company’s guiding principles?
• Which departments will I work closely with throughout my time in this profile?

Learn more: Quantitative Research

To summarize the discussion, an effective interview will be one that provides researchers with the necessary data to know the object of study and that this information is applicable to the decisions researchers make.

Undoubtedly, the objective of the research will set the pattern of what types of interviews are best for data collection. Based on the research design , a researcher can plan and test the questions, for instance, if the questions are correct and if the survey flows in the best way.

LEARN ABOUT: Best Data Collection Tools

In addition, other types of research can be used under specific circumstances.

For example, there are no connections or adverse situations to carry out surveyors. In these types of occasions, it is necessary to conduct field research, which can not be considered an interview if not rather a completely different methodology.

QuestionPro is a flexible online survey platform that can help researchers do different kinds of interviews, like structured, semi-structured, unstructured, phone interview, group interview, etc. It gives researchers a flexible platform that can be changed to fit their needs and the needs of their research project.

The 3 main types of interviews are 1. Structured interviews 2. Semi-structured interviews 3. Unstructured interviews

There are different ways to conduct an interview, and each one can add depth and substance to the information the interviewer gathers by asking questions. We discuss four interview methods: situational, professional behavior profiling, stress, and behavioral.

Face-to-face means in-person interviews are the most common type of interview. It’s about getting a good sense of the candidate by focusing on them directly. But it also allows the person interviewed to talk freely and ask questions.

Personal interviews, phone interviews, email or web page interviews, and a combination of these methods are the four types of research interviews.

Chapter 10: Qualitative Data Collection & Analysis Methods

10.5 Analysis of Qualitative Interview Data

Analysis of qualitative interview data typically begins with a set of transcripts of the interviews conducted. Obtaining said transcripts requires either having taken exceptionally good notes during an interview or, preferably, recorded the interview and then transcribed it. To transcribe an interview means to create a complete, written copy of the recorded interview by playing the recording back and typing in each word that is spoken on the recording, noting who spoke which words. In general, it is best to aim for a verbatim transcription, i.e., one that reports word for word exactly what was said in the recorded interview. If possible, it is also best to include nonverbal responses in the written transcription of an interview (if the interview is completed face-to-face, or some other form of visual contact is maintained, such as with Skype). Gestures made by respondents should be noted, as should the tone of voice and notes about when, where, and how spoken words may have been emphasized by respondents.

If you have the time, it is best to transcribe your interviews yourself. If the researcher who conducted the interviews transcribes them herself, that person will also be able to record associated nonverbal behaviors and interactions that may be relevant to analysis but that could not be picked up by audio recording. Interviewees may roll their eyes, wipe tears from their face, and even make obscene gestures that speak volumes about their feelings; however, such non-verbal gestures cannot be recorded, and being able to remember and record in writing these details as it relates to the transcribing of interviews is invaluable.

Overall, the goal of analysis is to reach some inferences, lessons, or conclusions by condensing large amounts of data into relatively smaller, more manageable bits of understandable information. Analysis of qualitative interview data often works inductively (Glaser & Strauss, 1967; Patton, 2001). To move from the specific observations an interviewer collects to identifying patterns across those observations, qualitative interviewers will often begin by reading through transcripts of their interviews and trying to identify codes. A code is a shorthand representation of some more complex set of issues or ideas. The process of identifying codes in one’s qualitative data is often referred to as coding . Coding involves identifying themes across interview data by reading and re-reading (and re-reading again) interview transcripts, until the researcher has a clear idea about what sorts of themes come up across the interviews. Coding helps to achieve the goal of data management and data reduction (Palys & Atchison, 2014, p. 304).

Coding can be inductive or deductive. Deductive coding is the approach used by research analysts who have a well-specified or pre-defined set of interests (Palys & Atchison, 2014, P. 304). The process of deductive coding begins with the analyst utilizing those specific or pre-defined interests to identify “relevant” passages, quotes, images, scenes, etc., to develop a set of preliminary codes (often referred to as descriptive coding ). From there, the analyst elaborates on these preliminary codes, making finer distinctions within each coding category (known as interpretative coding ). Pattern coding is another step an analyst might take as different associations become apparent. For example, if you are studying at-risk behaviours in youth, and you discover that the various behaviours have different characteristics and meanings depending upon the social context (e.g., school, family, work) in which the various behaviours occur, you have identified a pattern (Palys & Atchison, 2014, p. 304).

In contrast, inductive coding begins with the identification of general themes and ideas that emerge as the researcher reads through the data. This process is also referred to as open coding (Palys & Atchison, 2014, p. 305), because it will probably require multiple analyses. As you read through your transcripts, it is likely that you will begin to see some commonalities across the categories or themes that you’ve jotted down (Saylor Academy, 2012). The open coding process can go one of two ways: either the researcher elaborates on a category by making finer, and then even finer distinctions, or the researcher starts with a very specific descriptive category that is subsequently collapsed into another category (Palys & Atchison, 2014, p. 305). In other words, the development and elaboration of codes arise out of the material that is being examined.

The next step for the research analyst is to begin more specific coding, which is known as focused or axial coding . Focused coding involves collapsing or narrowing themes and categories identified in open coding by reading through the notes you made while conducting open coding, identifying themes or categories that seem to be related, and perhaps merging some. Then give each collapsed/merged theme or category a name (or code) and identify passages of data that fit each named category or theme. To identify passages of data that represent your emerging codes, you will need to read through your transcripts several times. You might also write up brief definitions or descriptions of each code. Defining codes is a way of giving meaning to your data, and developing a way to talk about your findings and what your data means (Saylor Academy, 2012).

As tedious and laborious as it might seem to read through hundreds of pages of transcripts multiple times, sometimes getting started with the coding process is actually the hardest part. If you find yourself struggling to identify themes at the open coding stage, ask yourself some questions about your data. The answers should give you a clue about what sorts of themes or categories you are reading (Saylor Academy, 2012). (Lofland and Lofland,1995, p. 2001) identify a set of questions that are useful when coding qualitative data. They suggest asking the following:

• Of what topic, unit, or aspect is this an instance?
• What question about a topic does this item of data suggest?
• What sort of answer to a question about a topic does this item of data suggest (i.e., what proposition is suggested)?

Asking yourself these questions about the passages of data that you are reading can help you begin to identify and name potential themes and categories.

Table 10.3 “ Interview coding” example is drawn from research undertaken by Saylor Academy (Saylor Academy, 2012) where she presents two codes that emerged from her inductive analysis of transcripts from her interviews with child-free adults. Table 10.3 also includes a brief description of each code and a few (of many) interview excerpts from which each code was developed.

Just as quantitative researchers rely on the assistance of special computer programs designed to help sort through and analyze their data, so, do qualitative researchers. Where quantitative researchers have SPSS and MicroCase (and many others), qualitative researchers have programs such as NVivo and Atlasti . These are programs specifically designed to assist qualitative researchers to organize, manage, sort, and analyze large amounts of qualitative data. The programs allow researchers to import interview transcripts contained in an electronic file and then label or code passages, cut and paste passages, search for various words or phrases, and organize complex interrelationships among passages and codes

Read our article (which includes example answers to get your brain juices flowing) to ensure you put your best foot forward for your next research interview.

• What are research interview questions?

If you have set your sights on working in research, you will have to answer research interview questions during the hiring process.

Whether you are interested in working as a research assistant or want to land an academic or industry research position in your chosen field, confidently answering research interview questions is the best way to showcase your skills and land the job.

Designed to be open-ended , research interview questions give your interviewer a chance to:

Get a better understanding of your research experience

Explore your areas of research expertise

Determine if you and your research are a good fit for their needs

Assess if they have the required resources for you to conduct your research effectively

• 12 research interview questions (with answers)

If you want to crush an upcoming interview for a research position, practicing your answers to commonly asked questions is a great place to start.

Read our list of research interview questions and answers to help get into the pre-interview zone (and, hopefully, ensure you land that position!)

• General research questions

General research questions are typically asked at the start of the interview to give the interviewer a sense of your work, personality, experience, and career goals. 

They offer a great opportunity to introduce yourself and your skills before you deep-dive into your specific area of expertise.

What is your area of research expertise?

Interviewers will ask this common kickoff question to learn more about you and your interests and experience. Besides providing the needed information, you can use this question to highlight your unique skills at the beginning of your interview to set the tone.

Example answer

“My research focuses on the interaction between social media use and teenager mental well-being. I’ve conducted [X number] studies which have been published in [X publications]. I love studying this topic because not only is it a pressing modern issue, it also serves a commonly overlooked population that requires and deserves additional attention and support.”

Why are you interested in [X research topic]?

Another icebreaker, this question allows you to provide some context and backstory into your passion for research.

“After completing my undergraduate degree in mechanical engineering, I had the opportunity to work with my current mentor on their research project . After we conducted the first experiment, I had a million other questions I wanted to explore—and I was hooked. From there, I was fortunate enough to be taken on as an assistant by my mentor, and they have helped me home in on my specific research topic over the past [X years].”

What are your favorite and least favorite aspects of research?

Playing off the classic “What are your greatest strengths and weaknesses?” interview question, this research-specific option often appears in these types of interviews.

This can be a tricky question to answer well. The best way to approach this type of question is to be honest but constructive. This is your opportunity to come across as genuine as you talk about aspects of research that challenge you—because no one wants to hear you like everything about your work!

“My favorite part of research is speaking directly to people in our target demographic to hear about their stories and experiences. My least favorite part is the struggle to secure grants to support my work—though now I have done that process a few times, it is less daunting than when I started.”

• In-depth interview questions about your research

Once the interviewer has a basic understanding of you, they will transition into asking more in-depth questions about your work.

Regardless of your level of experience, this is the portion of the interview where you can dazzle your potential employer with your knowledge of your industry and research topic to highlight your value as a potential employee.

Where has your work been published?

As this is a straightforward question, make sure you have to hand every place your work has been published. If your work is yet to be published, mention potential future publications and any other academic writing you have worked on throughout your career.

“My research has been published in [X number of publications]. If you want to read my published work, I am happy to share the publication links or print you a copy.”

Tell us about your research process

Getting into the meat and potatoes of your work, this question is the perfect opportunity to share your working process while setting clear expectations for the support you will need.

Research is a collaborative process between team members and your employer, so being clear about how you prefer to work (while acknowledging you will need to make compromises to adjust to existing processes) will help you stand out from other candidates.

“Historically, I have worked alongside a team of researchers to devise and conduct my research projects. Once we determine the topic and gather the needed resources, I strive to be collaborative and open as we design the study parameters and negotiate the flow of our work. I enjoy analyzing data, so in most cases, I take the lead on that portion of the project, but I am happy to jump in and support the team with other aspects of the project as well.”

What sources do you use to collect your research data?

Depending on the type of research you conduct, this question allows you to deep-dive into the specifics of your data-collection process. Use this question to explain how you ensure you are collecting the right data, including selecting study participants, filtering peer-reviewed papers to analyze, etc.

“Because my research involves collecting qualitative data from volunteers, I use strict criteria to ensure the people I interview are within our target demographic. During the interview, which I like doing virtually for convenience, I use [X software] to create transcripts and pool data to make the analysis process less time-consuming.”

• Leadership research questions

Many research positions require employees to take on leadership responsibilities as they progress throughout their careers.

If this is the case for your job position, have strong answers prepared to the following questions to showcase your leadership and conflict-management skills.

Are you interested in becoming a research leader or manager?

Many research positions are looking for people with leadership potential to take on more responsibility as they grow throughout their careers. If you are interested in pursuing research leadership, use this question to highlight your leadership qualities.

“While I currently do not have much research leadership experience, I have worked with so many lovely mentors, and I would love the opportunity to fulfill that role for the next generation of academics. Because I am quite organized and attuned to the challenges of research, I would love the opportunity to take on leadership responsibilities over time.”

How do you handle workplace conflicts within a research team?

Workplace conflict is always present when working with a team, so it is a common topic for research interview questions.

Despite being tricky to navigate, this type of question allows you to show you are a team player and that you know how to handle periods of interpersonal stress. 

“When I'm directly involved in a disagreement with my team members, I do my best to voice my opinion while remaining respectful. I am trained in de-escalation techniques, so I use those skills to prevent the argument from getting too heated. If I am a bystander to an argument, I try to help other team members feel heard and valued while disengaging any big emotions from the conversation.”

How would you support and motivate a struggling researcher on your team?

Research is a team effort. Employers are looking for people who can work well in teams as a priority when hiring. Describing your ability to support and encourage your team members is essential for crushing your research interview.

“Working in research is hard—so I have had my fair share of offering and receiving support. When I have noticed someone is struggling, I do my best to offset their workload (provided I have the space to assist). Also, because I pride myself on being a friendly and approachable person, I do my best to provide a safe, open space for my team members if they want to talk or vent about any issues.”

• Future-oriented research questions

As the interview comes to a close, your interviewer may ask you about your aspirations in academia and research.

To seal the deal and leave a positive impression, these types of questions are the perfect opportunity to remind your interviewer about your skills, knowledge base, and passion for your work and future in research.

What other areas of research are you interested in exploring?

Many hiring research positions may require their researchers to be open to exploring alternative research topics . If this applies to your position, coming prepared with adjacent topics to your current studies can help you stand out.

“While my primary interests are with my area of study, I also am interested in exploring [X additional topics] related to my current work.”

Where do you see your research in 5, 10, or 20 years?

Your employer wants to see you are interested in and invested in growing your research career with them. To scope out your aspirations (and to show you are a good match for their needs), they may ask you to detail your future career goals.

“In five years, I would love to have at least two more published projects, particularly in [X publication]. Past that, as I mature in my research career, I hope to take on more leadership roles in the next 10 to 20 years, including running my own lab or being invited to speak at conferences in my chosen field.”

In an ideal world, what would your perfect research job look like?

As a fun hypothetical question, the “ideal world” inquiry allows you to get creative and specific about your wishes and aspirations. If you get asked this question, do your best not to limit yourself. Be specific about what you want; you never know, some of your wishes may already be possible to fulfill!

“In an ideal world, I would love to be the lead of my own research team. We would have our own working space, access to [X specific research tool] to conduct our research, and would be able to attend conferences within our field as keynote speakers.”

• Get ready to ace your next research interview

Now you’re ready to dazzle your interviewers and land the research job of your dreams. Prepare strong and competent answers after reading this article on the most common research interview questions.

Arriving prepared for your interview is a great way to reduce stress, but remember: Showcasing yourself and your passion for your research is the number one way to stand out from the other applicants and get the job.

A year after Maine mass shooting, gunman's family wants action on brain injury research in military

LEWISTON, Maine — For the family of the Army reservist who carried out a mass shooting across Maine's second-largest city one year ago , dissecting what provoked the deadly rampage has been daunting.

Amid the heartbreak in Lewiston, where 18 people were massacred on the evening of Oct. 25, 2023, at  a bowling alley  hosting a youth night and  a bar where deaf people were playing cornhole, the gunman's family contemplated remaining quietly in the shadows.

But the unspeakable violence inflicted on this community has spurred a very public purpose for the family: bringing awareness to traumatic brain injuries among military members and a call to action for continued research.

"We want to make sure this doesn't ever, ever happen again to another family," said Nicole Herling, the sister of gunman Robert Card.

Card, 40, was found dead by suicide after an extensive two-day manhunt. A firearms and hand grenade instructor and longtime member of the Army Reserve, Card shared a teenage son with his ex-wife.

In the months leading up to the shooting, members of his family tried to get him help, including reaching out to a veterans crisis hotline about his erratic behavior and also placing multiple calls to his military base. They also noted he had complained about hearing voices when he was fitted for high-powered hearing aids and had a "manic belief" that people were against him. Other family members also alerted local law enforcement, which visited Card's home in the weeks before the shooting but did not make contact.

Maine's medical examiner requested a postmortem study of Card's brain, which was conducted by the Boston University CTE Center. The findings were staggering : There was "evidence of traumatic brain injury," researchers said, which "likely" played a role in his symptoms and aligned with previous studies on the effects of blast injuries.

During a hearing in May as part of an independent state commission's fact-finding investigation, the family members relayed that the researchers who studied his brain said it was "one of the worst" cases they had seen — even in comparison to military personnel who had served in Afghanistan and Iraq.

Card was never deployed in combat. Instead, as a hand grenade instructor, he was subject to potentially thousands of low-level blasts over his military career.

Herling stressed that her brother's traumatic brain injury findings don't fully explain his actions and that a brain injury doesn't mean someone is more likely to commit such violence.

Her husband, James, made it clear to the independent commission that any brain injury was not an excuse for Card's behavior or actions, which he called "a wrongful act of evil."

Boston University researchers had said they found no evidence the shooter suffered from chronic traumatic encephalopathy, or CTE, a degenerative brain disease associated with behavioral and cognitive issues related to repeated head injuries.

Still, the conclusion has given Herling a pathway for turning a tragedy into a meaningful mission.

"We had recognized that we needed to help other families, especially once we realized that Robbie's brain had been compromised," Herling said in an interview with NBC News anchor Lester Holt.

Through Card's brain being examined after his death, Herling learned about so-called brain banks, a collection of donated brain tissue used for research and education.

The Herlings are proponents of Project Enlist, an initiative of the Concussion Legacy Foundation , a nonprofit organization in Boston that is recruiting and conducting outreach to the military community to encourage veterans and service members to be part of a brain bank registry .

The research is being done through the UNITE Brain Bank, a collaboration between the Department of Veterans Affairs and Boston University.

The scientific understanding of traumatic brain injuries and related disorders is in its infancy, and having further research of military service members' brains will ultimately help create effective treatments and testing for living patients, said Dr. Chris Nowinski, the CEO and co-founder of the Concussion Legacy Foundation.

Since Project Enlist began in 2018, almost 300 veterans have donated their brains for research, with thousands more pledging to do the same, the group said, with the aim of having increased data similar to how athletes have been studied for CTE and other brain injuries.

"We're just starting to get a handle on which specific military roles are putting people at risk of CTE or repeated blast overpressure," Nowinski said, "and this is not a conversation we were having five years ago."

The Herlings are launching their own nonprofit organization, Rising Over Brokenness, to help start conversations about mental health awareness and brain injuries among service members. Herling's other brother, Ryan Card, is a retired Army ranger who became disabled as a result of deployments to Iraq and Afghanistan.

During the state commission hearing, Herling spoke openly about their brother's declining state of mind and how "his brain was not healthy."

"Here, I brought the very helmet meant to safeguard my brother's brain," she said, showing the commission the military headgear. "To the Department of Defense: It failed. It's been failing."

The Army r e lease d its own report into the shooting in July, admitting that there were "multiple errors" in how Card's unit handled him in the few months before the shooting as he was hospitalized in a psychiatric unit with reported symptoms of psychosis and homicidal ideations. But the Army report denied that any brain-related injury was linked to his military service.

Still, the military in August announced new guidance to minimize blast exposure among service members. They will conduct "baseline cognitive assessments" for its trainees and develop improved protective equipment.

Last week, lawyers representing 100 survivors and the family members of victims announced the intent to sue the Defense Department, the Army and an Army hospital in West Point, New York, that saw Card last summer for allegedly failing to respond to the warning signs and threats.

The Justice Department declined to comment on the claims.

In a statement, the Army said that it remains "deeply saddened" by the shooting and that leadership has reviewed the findings of its investigation and "put great effort in implementing all the recommendations and lessons learned."

Officials said the Army Reserve has completed several actions, including improving communication among a soldier's chain of command related to behavioral health, and is "expeditiously working on implementing additional recommendations."

Herling said she supports any litigation on behalf of the survivors and the victims to get "justice and accountability."

Among those who've filed a claim is Leroy Walker Sr., the father of Joseph Walker , a manager at Schemengees Bar and Grille, where he and nine other victims were killed.

Walker credits the gunman's family for treading carefully in the wake of the shooting.

"They've done everything, I think, that they could do to make this easier on everybody," Walker said. "So right from the beginning, I never held anything against them. They're a father and mother that raised a good son. And again, whatever drove him off the deep end, it's not their fault. It's not my fault. It's not your fault. It just happened."

The loss of his son, who was 57, is incalculable, he added.

"Every morning that I get up, he's the first person I think of and pretty much the last person when I go to sleep at night," Walker said. "It's been a tough, tough year."

The Herlings acknowledge that everyone, from their family to the Army to local law enforcement, had a responsibility to ensure Card's firearms were removed from his home as they grew increasingly concerned he might hurt himself or others.

Like Walker, the Herlings are remembering those killed as a reminder of how acutely lives have been altered. The names of all 18 victims — one as young as 14 and others in their 70s — are written on the walls of their home; outside, the names line their property with blue hearts signifying Lewiston.

"I don't ever want to talk about Robbie without acknowledging the pain that he's caused to other people," Nicole Herling said.

Her husband's voice broke as he thought of the children who no longer have their parents and those killed who were simply enjoying a night out before the sounds of laughter and amusement were replaced with panicked screams and cries for help.

"It's hard to hear it," James Herling said, "but we're using this as a fuel to be able to make sure that other people are aware of the struggles that are going on."
