Components of a Primary Research Study

As indicated on a previous page, Peer-Reviewed Journals also include non -primary content. Simply limiting your search results in a database to "peer-reviewed" will not retrieve a list of only primary research studies.

Learn to recognize the parts of a primary research study. Terminology will vary slightly from discipline to discipline and from journal to journal.  However, there are common components to most research studies.

When you run a search, find a promising article in your results list and then look at the record for that item (usually by clicking on the title). The full database record for an item usually includes an abstract or summary--sometimes prepared by the journal or database, but often written by the author(s) themselves. This will usually give a clear indication of whether the article is a primary study.  For example, here is a full database record from a search for family violence and support in SocINDEX with Full Text :

Although the abstract often tells the story, you will need to read the article to know for sure. Besides scanning the Abstract or Summary, look for the following components: (I am only capturing small article segments for illustration.)

Look for the words METHOD or METHODOLOGY . The authors should explain how they conducted their research.

NOTE: Different Journals and Disciplines will use different terms to mean similar things. If instead of " Method " or " Methodology " you see a heading that says " Research Design " or " Data Collection ," you have a similar indicator that the scholar-authors have done original research.

Look for the section called RESULTS . This details what the author(s) found out after conducting their research.

Charts , Tables , Graphs , Maps and other displays help to summarize and present the findings of the research.

A Discussion indicates the significance of findings, acknowledges limitations of the research study, and suggests further research.

References , a Bibliography or List of Works Cited indicates a literature review and shows other studies and works that were consulted. USE THIS PART OF THE STUDY! If you find one or two good recent studies, you can identify some important earlier studies simply by going through the bibliographies of those articles.

A FINAL NOTE:  If you are ever unclear about whether a particular article is appropriate to use in your paper, it is best to show that article to your professor and discuss it with them.  The professor is the final judge since they will be assigning your grade.

Evaluating Resources: Primary & Secondary Sources

Primary v. secondary sources.

A question to ask yourself when trying to identify primary or secondary sources is:

Did the person writing the thing do the thing?

While this may sound odd, the best indicator that something is a primary source is if the author of the piece actually DID the work that led to the creation of the resource.

These are some other things to consider with primary and secondary sources.

• Primary and secondary sources can be different publication types. Articles can be primary or secondary, just as books can be.
• Primary and secondary sources are not related to peer review in any way. Peer-reviewed articles can be either primary or secondary sources.
• There is no perfect database limiter for primary or secondary, either. There are no check boxes like there are with with peer review.
• Primary and secondary sources don't self identify as such. Nowhere in a primary source will it say, "this is a primary source." You need to evaluate the resource to figure it out.

Primary sources

In primary source documents, the person writing the piece actually did the research, or witnessed the event, or created something entirely new. These are some examples of primary sources:

• An author completes original research and then writes about it.
• An author writes about his or her experience of an event.
• An author creates an original theory or philosophy, and then writes about it.
• An author writes an original novel.

Secondary sources

Secondary sources evaluate or analyze what others have done or witnessed or created. The authors didn't go out and do it, they just analyzed it or wrote about it. These are some examples of secondary sources:

• Authors gather together a lot of primary research studies and then analyze them.  
• An author chooses a topic, finds a lot of articles on that topic, and writes about the topic based on other authors' research.  
• An author analyzes an original creative work.

Identifying primary & secondary sources

When looking at a resource to determine whether it is primary or secondary, words that describe the action of the author can be helpful. For example,  words like these can indicate actual research carried out:

• experimented
• investigated

In secondary resources, since the focus is on analyzing or discussion of a primary source, you would look for words that describe the action of the author indicating that this is an analysis or discussion, such as:

• reported on

You will need to examine the abstract and/or the article to determine if the resource is primary or secondary. While the words above can help indicate the type of resource, this is not a cut and dried process where if you see a particular word, that means the resource is always primary.

Locating a findings section in an article doesn't mean the source is either primary or secondary. Check to see whether the authors did the research themselves, or whether they analyzed research done by others.

Primary source example

For example, in the article, "School counselors' strategies for social justice change: A grounded theory of what works in the real world," these are some of the key elements from the abstract that indicate that it is a primary, research article:

• qualitative study
• grounded theory methodology
• explore the strategies that 16 school counselors
• Findings included seven overarching themes

The primary source authors actually talked to 16 school counselors, using grounded methodology, to come up with their findings based on the research that the authors actually did. Here, the authors did the research themselves and then reported on it.

Singh, A. A., Urbano, A., Haston, M., & McMahon, E. (2010). School counselors' strategies for social justice change: A grounded theory of what works in the real world. Professional School Counseling , 13 (3), 135-145. https://doi.org/10.5330/PSC.n.2010-13.135

• Abstract of School counselors' strategies for social justice change: A grounded theory of what works in the real world (PDF)

Secondary source example

This is an example of an article that is a secondary source, with some of the key elements highlighted:

In the article abstract, "Advocacy for health equity: A synthesis review," these are some of the key elements that indicate it is a secondary source article:

• aim of this review is to synthesize the evidence in the academic and gray literature
• systematic review of the academic literature and a fixed-length systematic search of the gray literature
• anaylzed our findings
• synthesized our findings
• made a critical appraisal of the literature
• brings together for the first time evidence from the academic and the gray literature and provides a building block for efforts to advocate for health equity

What makes the secondary source secondary is that the authors used other authors' research, analyzing and synthesizing the information to come up with their conclusions, or findings.

Farrer, L., Marinetti, C., Cavaco, Y. K., & Costongs, C. (2015). Advocacy for health equity: A synthesis review. Milbank Quarterly , 93 (2), 392-437. https://doi.org/10.1111/1468-0009.12112

Identifying Primary and Secondary Research Articles

• Primary and Secondary

Primary Research Articles

Primary research articles report on a single study. In the health sciences, primary research articles generally describe the following aspects of the study:

• The study's hypothesis or research question
• Some articles will include information on how participants were recruited or identified, as well as additional information about participants' sex, age, or race/ethnicity
• A "methods" or "methodology" section that describes how the study was performed and what the researchers did
• Results and conclusion section

Secondary Research Articles

Review articles are the most common type of secondary research article in the health sciences. A review article is a summary of previously published research on a topic. Authors who are writing a review article will search databases for previously completed research and summarize or synthesize those articles,  as opposed to recruiting participants and performing a new research study.

Specific types of review articles include:

• Systematic Reviews
• Meta-Analysis
• Narrative Reviews
• Integrative Reviews
• Literature Reviews

Review articles often report on the following:

• The hypothesis, research question, or review topic
• Databases searched-- authors should clearly describe where and how they searched for the research included in their reviews
• Systematic Reviews and Meta-Analysis should provide detailed information on the databases searched and the search strategy the authors used.Selection criteria-- the researchers should describe how they decided which articles to include
• A critical appraisal or evaluation of the quality of the articles included (most frequently included in systematic reviews and meta-analysis)
• Discussion, results, and conclusions

Determining Primary versus Secondary Using the Database Abstract

Information found in PubMed, CINAHL, Scopus, and other databases can help you determine whether the article you're looking at is primary or secondary.

Primary research article abstract

• Note that in the "Objectives" field, the authors describe their single, individual study.
• In the materials and methods section, they describe the number of patients included in the study and how those patients were divided into groups.
• These are all clues that help us determine this abstract is describing is a single, primary research article, as opposed to a literature review.
• Primary Article Abstract

Secondary research/review article abstract

• Note that the words "systematic review" and "meta-analysis" appear in the title of the article
• The objectives field also includes the term "meta-analysis" (a common type of literature review in the health sciences)
• The "Data Source" section includes a list of databases searched
• The "Study Selection" section describes the selection criteria
• These are all clues that help us determine that this abstract is describing a review article, as opposed to a single, primary research article.
• Secondary Research Article

Finding Scholarly Articles: Home

What's a Scholarly Article?

Your professor has specified that you are to use scholarly (or primary research or peer-reviewed or refereed or academic) articles only in your paper. What does that mean?

Scholarly or primary research articles are peer-reviewed , which means that they have gone through the process of being read by reviewers or referees  before being accepted for publication. When a scholar submits an article to a scholarly journal, the manuscript is sent to experts in that field to read and decide if the research is valid and the article should be published. Typically the reviewers indicate to the journal editors whether they think the article should be accepted, sent back for revisions, or rejected.

To decide whether an article is a primary research article, look for the following:

• The author’s (or authors') credentials and academic affiliation(s) should be given;
• There should be an abstract summarizing the research;
• The methods and materials used should be given, often in a separate section;
• There are citations within the text or footnotes referencing sources used;
• Results of the research are given;
• There should be discussion   and  conclusion ;
• With a bibliography or list of references at the end.

Caution: even though a journal may be peer-reviewed, not all the items in it will be. For instance, there might be editorials, book reviews, news reports, etc. Check for the parts of the article to be sure.   

You can limit your search results to primary research, peer-reviewed or refereed articles in many databases. To search for scholarly articles in  HOLLIS , type your keywords in the box at the top, and select  Catalog&Articles  from the choices that appear next.   On the search results screen, look for the  Show Only section on the right and click on  Peer-reviewed articles . (Make sure to  login in with your HarvardKey to get full-text of the articles that Harvard has purchased.)

Many of the databases that Harvard offers have similar features to limit to peer-reviewed or scholarly articles.  For example in Academic Search Premier , click on the box for Scholarly (Peer Reviewed) Journals  on the search screen.

Review articles are another great way to find scholarly primary research articles.   Review articles are not considered "primary research", but they pull together primary research articles on a topic, summarize and analyze them.  In Google Scholar , click on Review Articles  at the left of the search results screen. Ask your professor whether review articles can be cited for an assignment.

A note about Google searching.  A regular Google search turns up a broad variety of results, which can include scholarly articles but Google results also contain commercial and popular sources which may be misleading, outdated, etc.  Use Google Scholar  through the Harvard Library instead.

About Wikipedia .  W ikipedia is not considered scholarly, and should not be cited, but it frequently includes references to scholarly articles. Before using those references for an assignment, double check by finding them in Hollis or a more specific subject  database .

Still not sure about a source? Consult the course syllabus for guidance, contact your professor or teaching fellow, or use the Ask A Librarian service.

To make the process easier, it is important to understand the search interface and refine your results with filters and preferences.

The first step in searching for primary research articles on Google Scholar is understanding the search interface. This includes learning how to use keywords, Boolean operators (AND, OR, NOT), quotation marks (” “) for exact phrases, and wildcards (*). These search parameters can be employed to refine the results, making them pertinent to your inquiry.

Utilizing filters and personal preferences to narrow down search results can expedite the discovery of what is needed. With advanced features like citation tracking, “My Library” which allows users to save their searches, and “Similar Articles” for discovering related topics within a field of study, the research process is made easier. Additionally, keywords such as Boolean operators (AND, OR NOT), quotation marks (” “) for exact phrases, and wildcards (*) can be used to narrow down results in order to make them more relevant.

Finally, finding full-text articles is key when researching primary research papers on Google Scholar. The platform offers access to free versions of some publications through its “Find Full Text @ Your Library” feature but many require a subscription or purchase fee before viewing them in full detail online or downloading them as PDFs.

Exploring Google Scholar for primary research articles can be laborious, yet with some useful tips and tricks you can enhance your search results.

Google Scholar is an invaluable tool for researchers, scientists, and engineers looking to stay up-to-date on the latest research in their field. With its advanced search features, it can help you quickly find primary research articles that are relevant to your project or interests. Here are some suggestions to optimize your utilization of Google Scholar when seeking out primary research papers.

Google Scholar has several advanced search options that allow you to refine your searches and find more specific results. For example, you can limit your search by date range, language, author name, or journal title. Boolean operators, like “AND” and “OR”, can be utilized to form a single query by combining various keywords.

To refine your search even further, you can utilize the filters and preferences available on Google Scholar to narrow down results according to peer-reviewed papers from journals with high-impact factors or exclude certain authors or topics. For instance, if you want only peer-reviewed papers from journals with high-impact factors then simply select those filters before conducting your search. Additionally, if there are certain authors or topics that you would like excluded from your results then this too can be done via the preferences menu within Google Scholar.

Once you have located some applicable articles through basic keyword searches, delving into associated citations and related content can help to expand your understanding of the topic. This is especially helpful if there is not much information available on a particular subject yet, but still offers potential avenues of exploration worth pursuing further down the line. By exploring related articles and citations associated with each article one will often uncover new ideas which could potentially lead them toward interesting discoveries.

By making use of the sophisticated search capabilities, filters, and preferences provided by Google Scholar, one can easily identify primary research material related to their requirements. My Library on Google Scholar is an excellent tool for organizing and tracking your research; let’s explore how it works.

Key Takeaway  Google Scholar provides advanced search features, filters and preferences to help researchers quickly locate primary research articles relevant to their project or interests. By making use of these tools and exploring related articlescitations associated with each article one can uncover new ideas that could lead them towards interesting discoveries. Google Scholar is a great aid in locating pertinent research articles.

My Library on Google Scholar is a great asset for scientists and innovators to monitor their research progress. My Library enables users to construct a personalized repository of scholarly works, which they can organize into categories, export as bibliographies, or share with others.

Setting up a personal library in My Library is easy. To create a personal library, simply click the “My Library” link at the top right corner of any page on Google Scholar and select “Create new library” from the drop-down menu. Once your library has been created, you can start adding articles by clicking the “Save” button next to each article title in your search results list.

Organizing your library is also simple; simply drag and drop articles into different folders within My Library for easy access later on. You can also create collections of related topics or research themes which are great for organizing large amounts of data quickly and easily. Moreover, you can label articles with descriptors to make them easier to locate when needed.

By utilizing My Library on Google Scholar, researchers can easily keep track of their research and stay organized. Additionally, by exploring other databases in conjunction with Google Scholar as well as open-access journals and interlibrary loan services, they can find even more primary research articles to further their studies.

Key Takeaway  My Library on Google Scholar is a great resource for researchers and innovators to stay organized with their research. Creating a library is straightforward – just hit the ‘Create new library’ button in the top right of any page on Google Scholar, and then drag & drop articles into collections or folders to keep them ordered. Moreover, you can assign labels or tags to make it simpler to locate the material when necessary.

It can provide access to a wide variety of sources, including journal articles, books, and conference papers. Nevertheless, in order to broaden one’s search range, other databases and sources can be used alongside Google Scholar.

Using Other Databases in Conjunction with Google Scholar: Many academic institutions have their own subscription-based library databases that can be accessed through the institution’s website or portal. These databases may include full-text versions of some journals not available on Google Scholar as well as more comprehensive indexing than what is available on Google Scholar. Moreover, numerous universities offer access to specialized databases such as Web of Science or Scopus that enable users to search across multiple areas and sources simultaneously.

Open-access journals, which receive funding from sources such as the NIH and Wellcome Trusts, provide free online content under Creative Commons licenses for readers to share or reuse without permission. Open-access journals typically make all content freely available online and often use Creative Commons licenses so readers are free to share and reuse material without permission from the publisher or author(s). While these publications tend to focus more heavily on scientific topics rather than humanities topics they still contain valuable information worth exploring when searching for primary research articles related specifically to science fields such as biology or medicine.

If a desired article cannot be located elsewhere, interlibrary loan services may provide an avenue to acquire it through either physical or digital means. Through this service, users can request copies of materials held by another library either physically (through mail) or electronically (via email). This allows researchers who do not have immediate access to certain materials due to geographical restrictions the ability to acquire them nonetheless, thus greatly expanding their research capabilities beyond what would otherwise be possible with just local resources alone.

Key Takeaway  Google Scholar is a great tool for finding primary research articles, however there are other databases and resources that can be used in conjunction with it to maximize search capabilities. Additionally, open access journals may provide valuable content related to scientific fields while interlibrary loan services can also help researchers acquire materials from libraries located elsewhere.

To search for primary articles in Google Scholar, first, go to the main page and select ‘Advanced Search’. In the Advanced Search window, check off the box that says ‘Only show results from content I can access’ and then select ‘Include Patents’. Finally, click on ‘Search’. This will filter out all secondary sources such as reviews or books, leaving only primary research articles relevant to your query.

Primary research materials can be obtained through multiple avenues, such as searching online repositories, utilizing sophisticated search strategies, and consulting specialists in the discipline. Utilizing PubMed and other online databases, researchers can access an abundance of primary research articles covering a broad range of topics. Advanced search techniques involve combining keywords with Boolean operators (AND/OR) to refine searches for specific results. Consulting experts in the field is also an effective way to locate relevant primary research articles as they have specialized knowledge about certain areas that may not be available from other sources.

Begin your hunt for research articles on Google Scholar by inputting a keyword or phrase in the search field. You can refine your search results by applying filters such as date of publication, author name, and topic area. To further narrow down your search results you can use advanced search features like exact phrases and multiple keywords. Additionally, you may access scholarly literature through library databases that are connected to Google Scholar. Finally, save time by setting up email alerts for newly published papers related to topics of interest.

A primary source is an original document or record that provides first-hand information about a particular topic. Examples of primary sources can include interviews, diaries, letters, articles from when an event occurred, and photos and videos taken during the occurrence. Secondary sources are documents or records created after the fact by someone who did not experience the events firsthand. These may include books, journal articles, and reviews that analyze or discuss research already published by others.

How to find primary research articles on Google Scholar is an essential skill for researchers and innovators. With its advanced search capabilities, My Library feature, and additional resources available online, it can be an invaluable asset in the quest to discover new insights into any given topic.

A primary research article reports on an empirical research study conducted by the authors. It is almost always published in a peer-reviewed journal. This type of article:

• Asks a research question or states a hypothesis or hypotheses
• Identifies a research population
• Describes a specific research method
• Tests or measures something
• Includes a section called "method" or "methodology." This may only appear in the article, not the abstract.
• Includes a section called "results."

Words to look for as clues include: analysis, study, investigation, examination, experiment, numbers of people or objects analyzed, content analysis, or surveys.

To contrast, the following are not primary research articles (i.e., they are secondary sources):

• Literature reviews
• Meta-Analyses/Review articles (These are studies that arrive at conclusions based on research from many other studies.)
• Chapters in books
• Encyclopedia articles
• Speeches and interviews

Primary vs. Secondary Research Articles

In the sciences,  primary (or empirical) research articles :

• are original scientific reports of new research findings (Please note that an original scientific article does not include review articles, which summarize the research literature on a particular subject, or articles using meta-analyses, which analyze pre-published data.)
• usually include the following sections: Introduction , Methods , Results , Discussion, References
• are usually  peer-reviewed (examined by expert(s) in the field before publication). Please note that a peer-reviewed article is not the same as a review article, which summarizes the research literature on a particular subject

You may also choose to use some secondary sources (summaries or interpretations of original research) such as books (find these through the library catalog) or review articles (articles which organize and critically analyze the research of others on a topic). These secondary sources, particularly review articles, are often useful and easier-to-read summaries of research in an area. Additionally, you can use the listed references to find useful primary research articles.

Anatomy of a Scholarly Article

from NCSU Libraries' Anatomy of a Scholarly Article

Types of health studies

In the sciences, particularly the health sciences, there are a number of types of primary articles (the gold standard being randomized controlled trials ) and secondary articles (the gold standard being systematic reviews and meta-analysis ). The chart below summarizes their differences and the linked article gives more information.

Searching for Primary vs. Secondary Articles

Some scholarly databases will allow you to specific what kind of scholarly literature you're looking for.  However, be careful! Sometimes, depending on the database, the Review article type may mean book review instead of or as well as review article. You may also have to look under more or custom options to find these choices.

Primary Research | Definition, Types, & Examples

Published on 15 January 2023 by Tegan George .

Primary research is a research method that relies on direct data collection , rather than relying on data that’s already been collected by someone else. In other words, primary research is any type of research that you undertake yourself, firsthand, while using data that has already been collected is called secondary research.

Primary research is often used in qualitative research , particularly in survey methodology, questionnaires, focus groups, and various types of interviews . While quantitative primary research does exist, it’s not as common.

Primary research is any research that you conduct yourself. It can be as simple as a 2-question survey, or as in-depth as a years-long longitudinal study . The only key is that data must be collected firsthand by you.

Primary research is often used to supplement or strengthen existing secondary research. It is usually exploratory in nature, concerned with examining a research question where no preexisting knowledge exists. It is also sometimes called original research for this reason.

Prevent plagiarism, run a free check.

Primary research can take many forms, but the most common types are:

• Surveys and questionnaire
• Observational studies
• Interviews and focus groups
• Surveys and questionnaires

Surveys and questionnaires collect information about a group of people by asking them questions and analyzing the results. They are a solid choice if your research topic seeks to investigate something about the characteristics, preferences, opinions, or beliefs of a group of people.

Surveys and questionnaires can take place online, in person, or through the mail. It is best to have a combination of open-ended and closed-ended questions, and how the questions are phrased matters. Be sure to avoid leading questions, and ask any related questions in groups, starting with the most basic ones first.

Observational studies are an easy and popular way to answer a research question based purely on what you, the researcher, observes. If there are practical or ethical concerns that prevent you from conducting a traditional experiment , observational studies are often a good stopgap.

There are three types of observational studies: cross-sectional studies , cohort studies, and case-control studies. If you decide to conduct observational research, you can choose the one that’s best for you. All three are quite straightforward and easy to design – just beware of confounding variables and observer bias creeping into your analysis.

Similarly to surveys and questionnaires, interviews and focus groups also rely on asking questions to collect information about a group of people. However, how this is done is slightly different. Instead of sending your questions out into the world, interviews and focus groups involve two or more people – one of whom is you, the interviewer, who asks the questions.

There are 3 main types of interviews:

• Structured interviews ask predetermined questions in a predetermined order.
• Unstructured interviews are more flexible and free-flowing, proceeding based on the interviewee’s previous answers.
• Semi-structured interviews fall in between, asking a mix of predetermined questions and off-the-cuff questions.

While interviews are a rich source of information, they can also be deceptively challenging to do well. Be careful of interviewer bias creeping into your process. This is best mitigated by avoiding double-barreled questions and paying close attention to your tone and delivery while asking questions.

Alternatively, a focus group is a group interview, led by a moderator. Focus groups can provide more nuanced interactions than individual interviews, but their small sample size means that external validity is low.

Primary research can often be quite simple to pursue yourself. Here are a few examples of different research methods you can use to explore different topics.

Primary research is a great choice for many research projects, but it has distinct advantages and disadvantages.

Advantages of primary research

Advantages include:

• The ability to conduct really tailored, thorough research, down to the ‘nitty-gritty’ of your topic . You decide what you want to study or observe and how to go about doing that.
• You maintain control over the quality of the data collected, and can ensure firsthand that it is objective, reliable , and valid .
• The ensuing results are yours, for you to disseminate as you see fit. You maintain proprietary control over what you find out, allowing you to share your findings with like-minded individuals or those conducting related research that interests you for replication or discussion purposes.

Disadvantages of primary research

Disadvantages include:

• In order to be done well, primary research can be very expensive and time consuming. If you are constrained in terms of time or funding, it can be very difficult to conduct your own high-quality primary research.
• Primary research is often insufficient as a standalone research method, requiring secondary research to bolster it.
• Primary research can be prone to various types of research bias . Bias can manifest on the part of the researcher as observer bias , Pygmalion effect , or demand characteristics . It can occur on the part of participants as a Hawthorne effect or social desirability bias .

The 3 main types of primary research are:

Exploratory research explores the main aspects of a new or barely researched question.

Explanatory research explains the causes and effects of an already widely researched question.

There are several methods you can use to decrease the impact of confounding variables on your research: restriction, matching, statistical control, and randomisation.

In restriction , you restrict your sample by only including certain subjects that have the same values of potential confounding variables.

In matching , you match each of the subjects in your treatment group with a counterpart in the comparison group. The matched subjects have the same values on any potential confounding variables, and only differ in the independent variable .

In statistical control , you include potential confounders as variables in your regression .

In randomisation , you randomly assign the treatment (or independent variable) in your study to a sufficiently large number of subjects, which allows you to control for all potential confounding variables.

A questionnaire is a data collection tool or instrument, while a survey is an overarching research method that involves collecting and analysing data from people using questionnaires.

When conducting research, collecting original data has significant advantages:

• You can tailor data collection to your specific research aims (e.g., understanding the needs of your consumers or user testing your website).
• You can control and standardise the process for high reliability and validity (e.g., choosing appropriate measurements and sampling methods ).

However, there are also some drawbacks: data collection can be time-consuming, labour-intensive, and expensive. In some cases, it’s more efficient to use secondary data that has already been collected by someone else, but the data might be less reliable.

What is peer review? What does "Scholarly/Academic" mean?

What is "peer review"?  Peer review is a process conducted by many academic publishers to assess author submissions before publication. It aims to ensure that the content being published (typically in an academic journal article or book) is written to the highest standard, adheres to subject-specific research methodology, and contributes something new to an academic field. Importantly, peer-review is done at the article level and published within a journal issue. There may be an editorial at the beginning of a journal issue that is not peer-reviewed, followed by a number of journal articles that are peer-reviewed. Similarly, an academic book (or monograph) published by an academic press might contain a collection of chapters published by different authors, each of which are peer-reviewed, with an introductory chapter by the editors that is not peer reviewed.

Different stages of the peer review process.  Having a manuscript go through the peer-review process can take significant time, lasting for months or even years. Typically the process goes as follows:

A researcher in any field submits their manuscript to a relevant academic publisher for inclusion in one of their journals or for publication as a standalone book (also known as a monograph).

The editors of the publication review the submission to decide whether or not to send the manuscript to multiple subject experts (the "peers") for review. These peer-reviewers are experts in their field and are often (but not always) employed as faculty members at universities. 

The reviewers receive the manuscript with all information about the author and their institution removed. Making the manuscript anonymous helps ensure that the process is "blind," meaning that bias is removed in cases when the reviewers know the author(s).

The reviewers take time to review the submission and make suggestions on how to improve the work. The reviewers might also reject the work outright if they find it to be of substandard quality, or if they feel it is unoriginal. 

The author receives any recommended revisions or questions from the reviewers and is asked to implemented the changes. The author resubmits the revised manuscript. Once all requested revisions have been made, the peer reviewers and the editors of the journal will proceed with formally accepting the study for future publication.

What does "Scholarly/Academic" refer to?  Peer-reviewed publications are often captured by a "Scholarly/Academic" filter in databases or by a "Peer Review" filter. Note: in most databases, the "Scholarly/Academic" filter will retrieve results that are mainly peer-reviewed studies, but not every single result will necessarily be peer-reviewed. Certain results can be "Scholarly/Academic" without being peer-reviewed. Accordingly, it is important to take additional steps to determine whether or not a study has been peer reviewed. Indicators of a peer-reviewed article or book chapter include:

Evidence of research, which can include either footnotes or a bibliography.

Evidence of expertise, as indicated in the author's credentials (also referred to as "author affiliation").

Explanation of research methodology.

Fairly plain journal format. Few photographs or illustrations, mostly charts or graphs.

Few advertisements.

Note:  The word “Journal” in the title is NOT an indicator that you are looking at a scholarly journal. 

Where can I find a peer-reviewed study?

The short answer is to search in one or more of the library's many subject databases . Think of the library's databases as a more reliable place to locate peer-reviewed resources than commercial search engines such as Google (or even broad academic search engines such as Google Scholar). Being highly curated in terms of what titles are indexed, these search tools help to exclude sources that may be discredited or unreliable, such as predatory journals . 

Read the database descriptions when you are deciding which one to search. Many of the database descriptions provided in our a-z list will identify whether or not they contain peer-reviewed journals and/or monographs.

Many databases also provide convenient filters to limit your results to peer-reviewed studies. 

Checking for peer review in EBSCO's interface

The majority of EBSCO databases offer a reliable way to verify whether or not a specific journal is a peer-reviewed resource.

Follow these steps to determine if a journal publishes peer-reviewed articles.

Select any of the EBSCO subject databases .

Enter the journal's name. In the example included below in the screenshot, the example of "JAMA: Journal of the American Medical Association" is searched in Academic Search Complete .

Upon clicking this link, a detailed page about the publication should open. Towards the bottom of the page, there should be a field for "Peer Reviewed." If the notation is "YES," then the journal publishes peer-reviewed articles, as can be seen in the following screenshot:

Understanding EBSCO icons

You will see icons to the left of individual results when searching in databases provided by EBSCO. These icons mean different things, and their meaning can also vary across different databases, but, in general, they mean the following:

Many EBSCO databases use the following icon to signify Academic Journal (which contain peer-reviewed articles)

Many EBSCO databases use the following icon to identify Periodical sources (which are not peer reviewed)

What is a "Primary Research Article"?

Keep in mind that primary research articles . . .

are  original scientific reports  of new research findings

do not include review articles , which summarize the research literature on a particular subject, or articles using meta-analyses , which analyze pre-published data

usually include the following sections:  Introduction ,  Methods ,  Results ,  Discussion, References

are  peer-reviewed  (examined by expert(s) in the field before publication)

a peer-reviewed article is not the same as a review article, which summarizes the research literature on a particular subject

Keep in mind that secondary sources . . .

are summaries or interpretations of original research – not the original research itself

are often useful and easier-to-read summaries of research in an area

references or citations can point the way to useful primary research articles.

acceptable formats may include books (find these through the library catalog) and review articles (articles which organize and critically analyze the research of others on a topic)

blogs, YouTube videos, newspaper articles, book reviews, press releases and .com websites are NOT among formats usually appropriate as sources in scientific research

What is primary research in the sciences?

Primary sources in the sciences are typically academic journals. In them, the authors present their "primary" or original research. You may have heard of primary sources before in a history class, and the same idea applies here. A primary source is all about proximity. The authors should have firsthand experience with the content. In the sciences, that means that they conducted the research themselves.

How can I identify primary research in the sciences?

Here are five common components of primary research articles in the sciences. Check your source for these to help determine if you are looking at a primary source.

1. Written by experts who did the research

In a primary source, the authors report on research they conducted themselves. The best way to determine this is to read the introduction of the paper where the authors will explain what they are presenting. If the authors report only about someone else’s research or a different study, it is not primary. 

2. Reports on original research

This is closely tied to the first component. Did the authors of the article study something "new?" Did they delve into an issue to explore it further? Look for keywords in the abstract and introduction that tell you that the authors studied something. Keywords to look for include: "measured," "analyzed," and "investigated."

3. Describes how the authors did their study

A primary research article will describe the methods used to conduct the study. It ought to be detailed enough that the study could be replicated. Many primary research articles follow a common format with particular section headings. One of these is "methodology" or "methods." The methodology section is where the authors will explain how they did their study. Looking for this section heading is a good way to check for this factor. Even if this specific heading is missing, your article should still explain this to be primary.

4. Describes the study's results

The article should also clearly explain the results or outcomes of the research. Often you will see statistics, graphs, and/or tables in the article. These depictions of data in primary research articles will differ from the "decorative" images you may see in popular sources. Headings to look at for this factor include "results," "findings," and "discussion."

5. Always includes references

Finally, your primary research article will always include references. These could look like footnotes, a references section, or a works cited at the end of the article. Many articles that are not primary research articles - and even some that are not scholarly - include references. Do not make your decision of whether your article is primary or not based on this factor alone.

How can I learn more about identifying primary sources?

The phrase "Primary" can mean something different depending on what subject you're in.

In History , for example, you might hear the phrase "primary sources." This means the researcher is looking for sources that date back to when an event occurred. Primary sources can be a diary, a photograph, or a newspaper clipping.

If this is the kind of research you're looking for, check out this research guide on how to find primary sources:

• Primary Sources

If you're in Nursing or another scientific field you're more likely to hear the phrase "Primary Research."

Primary Research refers to research that was conducted by the author of the article you're reading. So if you're reading an article and in the methodology section the author refers to recruiting participants, identifying a control group, etc. you can be pretty sure the author has conducted the research themselves.

When you're asked to find primary research, you're being asked to find articles describing research that was conducted by the authors.

Check out the video below for an explanation of the differences between primary and secondary research.

To determine if the article you're looking at is considered Primary Research, look for the following:

• In the Abstract, can you find a description of research being conducted?
• Were participants recruited?
• Were surveys distributed?

The main question to ask yourself is "Did the author conduct research, or did they read and synthesize other people's research?"

If you've found an article in CINAHL and you want to know if it's primary research, look under "Publication Type" to see if it's a research article.

This is not always 100% correct, though. To be sure, you should always read the Methodology section to understand what kind of article you're looking at.

If you're using PubMed, you can check the article's Keywords and Abstract for clues to see if the article is primary research, like in the article below:

Or you can check to see if the article includes a "Publication Type" section like this article:

The following Publication Types are usually considered Primary Research:

• Adaptive Clinical Trial
• Clinical Study
• Clinical Trial
• Controlled Clinical Trial
• Equivalence Trial
• Evaluation Studies
• Observational Study
• Pragmatic Clinical Trial
• Randomized Controlled Trial

Remember, you will always need to read the Methodologies section of an article to be sure the article is an example of primary research!

In certain databases you can specify that you're only interested in resources that are considered primary research.

Two of those databases are CINAHL and PubMed, which you can access here:

To limit your results to primary research in CINAHL, check the "Research Article" box on the homepage before you hit "Search"

This check box is helpful, but it isn't 100% correct, so always read the Methodology section of your article to determine what kind of article it is!

If you're conducting a search in PubMed and want to limit your results to a certain kind of article, you can enter your search terms on the homepage and click "Search."

Then, when you're on your results page, use the limiters on the left side of the screen to specify the "Article Type" you're interested in. Under "Article Types" click the "Customize..." link to see the full list of article types available to you.

Check any of the article types you're interested in (don't forget to scroll down on this list!) and then click the blue "Show" button at the bottom of the pop up window.

Now the Article Types you just selected should appear under the Article Types heading. Click on the article types you want to show up in your results list and your results will limit themselves to just those that meet your criteria.

Remember to read the article's Methodology section yourself before deciding whether or not it's Primary Research! These limits are great, but they aren't always 100% accurate.

How Can I Find Primary Research Articles?

Many of the recommended databases in this subject guide contain primary research articles (also known as empirical articles or research studies). Search in databases like ScienceDirect , MEDLINE , and Health Source: Nursing/Academic Edition .

Primary Research Articles: How Will I Know One When I See One?

Primary research articles  to conduct and publish an experiment or research study, an author or team of authors designs an experiment, gathers data, then analyzes the data and discusses the results of the experiment. a published experiment or research study will therefore  look  very different from other types of articles (newspaper stories, magazine articles, essays, etc.) found in our library databases. the following guidelines will help you recognize a primary research article, written by the researchers themselves and published in a scholarly journal., structure of a primary research article typically, a primary research article has the following sections:.

• The author summarizes her article
• The author discusses the general background of her research topic; often, she will present a literature review, that is, summarize what other experts have written on this particular research topic
• The author describes the study she designed and conducted
• The author presents the data she gathered during her experiment
• The author offers ideas about the importance and implications of her research findings, and speculates on future directions that similar research might take
• The author gives a References list of sources she used in her paper

The structure of the article will often be clearly shown with headings: Introduction, Method, Results, Discussion.

A primary research article will almost always contains statistics, numerical data presented in tables. Also, primary research articles are written in very formal, very technical language.

How to identify peer reviewed journals, how to identify primary research articles.

• Journal of Animal Science
• Interlibrary Loan

Peer review is defined as “a process of subjecting an author’s scholarly work, research or ideas to the scrutiny of others who are experts in the same field” ( 1 ). Peer review is intended to serve two purposes:

• It acts as a filter to ensure that only high quality research is published, especially in reputable journals, by determining the validity, significance and originality of the study.
• Peer review is intended to improve the quality of manuscripts that are deemed suitable for publication. Peer reviewers provide suggestions to authors on how to improve the quality of their manuscripts, and also identify any errors that need correcting before publication.

How do you determine whether an article qualifies as being a peer-reviewed journal article?

• If you're searching for articles in certain databases, you can limit your search to peer-reviewed sources simply by selecting a tab or checking a box on the search screen.
• If you have an article, an indication that it has been through the peer review process will be the publication history , usually at the beginning or end of the article.
• If you're looking at the journal itself, go to the  editorial statement or instructions to authors  (usually in the first few pages of the journal or at the end) for references to the peer-review process.
• Lookup the journal by title or ISSN in the ProQuest Source Evaluation Aid . 
• Careful! Not all information in a peer-reviewed journal is actually reviewed. Editorials, letters to the editor, book reviews, and other types of information don't count as articles, and may not be accepted by your professor.

What about preprint sites and ResearchGate?

• A preprint is a piece of research that has not yet been peer reviewed and published in a journal. In most cases, they can be considered final drafts or working papers. Preprint sites are great sources of current research - and most preprint sites will provide a link to a later, peer-reviewed version of an article. 
• ResearchGate is a commercial social networking site for scientists and researchers to share papers, ask and answer questions, and find collaborators. Members can upload research output including papers, chapters, negative results, patents, research proposals, methods, presentations, etc. Researchers can access these materials, and also contact members to ask for access to material that has not been shared, usually because of copyright restrictions. There is a filter to limit results to articles, but it can be difficult to determine the publication history of ResearchGate items and whether they have been published in peer reviewed sources.

A primary research article reports on an empirical research study conducted by the authors. The goal of a primary research article is to present the result of original research that makes a new contribution to the body of knowledge. 

Characteristics:

• Almost always published in a peer-reviewed journal
• Asks a research question or states a hypothesis or hypotheses
• Identifies a research population
• Describes a specific research method
• Tests or measures something
• Often (but not always) structured in a standard format called IMRAD: Introduction, Methods, Results, and Discussion
• Words to look for as clues include: analysis, study, investigation, examination, experiment, numbers of people or objects analyzed, content analysis, or surveys.

To contrast, the following are not primary research articles (i.e., they are secondary sources):

• Literature reviews/Review articles
• Meta-Analyses (studies that arrive at conclusions based on research from many other studies)
• Editorials & Letters
• Dissertations

Articles that are NOT primary research articles may discuss the same research, but they are not reporting on original research, they are summarizing and commenting on research conducted and published by someone else. For example, a literature review provides commentary and analysis of research done by other people, but it does not report the results of the author's own study and is not primary research.

Characteristics of a Primary Research Article

• Goal is to present the result of original research that makes a new contribution to the body of knowledge
• Sometimes referred to as an empirical research article
• Typically organized into sections that include:  Abstract, Introduction, Methods, Results, Discussion/Conclusion, and References.

Example of a Primary Research Article:

Characteristics of a Review Article

• Goal is to summarize important research on a particular topic and to represent the current body of knowledge about that topic.
• Not intended to provide original research but to help draw connections between research studies that have previously been published.  
• Help the reader understand how current understanding of a topic has developed over time and identify gaps or inconsistencies that need further exploration.

Primary vs. Secondary Sources | Difference & Examples

Published on June 20, 2018 by Raimo Streefkerk . Revised on May 31, 2023.

When you do research, you have to gather information and evidence from a variety of sources.

Primary sources provide raw information and first-hand evidence. Examples include interview transcripts, statistical data, and works of art. Primary research gives you direct access to the subject of your research.

Secondary sources provide second-hand information and commentary from other researchers. Examples include journal articles, reviews, and academic books . Thus, secondary research describes, interprets, or synthesizes primary sources.

Primary sources are more credible as evidence, but good research uses both primary and secondary sources.

Table of contents

What is a primary source, what is a secondary source, primary and secondary source examples, how to tell if a source is primary or secondary, primary vs secondary sources: which is better, other interesting articles, frequently asked questions about primary and secondary sources.

A primary source is anything that gives you direct evidence about the people, events, or phenomena that you are researching. Primary sources will usually be the main objects of your analysis.

If you are researching the past, you cannot directly access it yourself, so you need primary sources that were produced at the time by participants or witnesses (e.g. letters, photographs, newspapers ).

If you are researching something current, your primary sources can either be qualitative or quantitative data that you collect yourself (e.g. through interviews , surveys , experiments ) or sources produced by people directly involved in the topic (e.g. official documents or media texts).

Prevent plagiarism. Run a free check.

A secondary source is anything that describes, interprets, evaluates, or analyzes information from primary sources. Common examples include:

• Books , articles and documentaries that synthesize information on a topic
• Synopses and descriptions of artistic works
• Encyclopedias and textbooks that summarize information and ideas
• Reviews and essays that evaluate or interpret something

When you cite a secondary source, it’s usually not to analyze it directly. Instead, you’ll probably test its arguments against new evidence or use its ideas to help formulate your own.

Examples of sources that can be primary or secondary

A secondary source can become a primary source depending on your research question . If the person, context, or technique that produced the source is the main focus of your research, it becomes a primary source.

Documentaries

If you are researching the causes of World War II, a recent documentary about the war is a secondary source . But if you are researching the filmmaking techniques used in historical documentaries, the documentary is a primary source .

Reviews and essays

If your paper is about the novels of Toni Morrison, a magazine review of one of her novels is a secondary source . But if your paper is about the critical reception of Toni Morrison’s work, the review is a primary source .

Newspaper articles

If your aim is to analyze the government’s economic policy, a newspaper article about a new policy is a secondary source . But if your aim is to analyze media coverage of economic issues, the newspaper article is a primary source .

To determine if something can be used as a primary or secondary source in your research, there are some simple questions you can ask yourself:

• Does this source come from someone directly involved in the events I’m studying (primary) or from another researcher (secondary)?
• Am I interested in evaluating the source itself (primary) or only using it for background information (secondary)?
• Does the source provide original information (primary) or does it comment upon information from other sources (secondary)?

Most research uses both primary and secondary sources. They complement each other to help you build a convincing argument. Primary sources are more credible as evidence, but secondary sources show how your work relates to existing research. Tertiary sources are often used in the first, exploratory stage of research.

What do you use primary sources for?

Primary sources are the foundation of original research. They allow you to:

• Make new discoveries
• Provide credible evidence for your arguments
• Give authoritative information about your topic

If you don’t use any primary sources, your research may be considered unoriginal or unreliable.

What do you use secondary sources for?

Secondary sources are good for gaining a full overview of your topic and understanding how other researchers have approached it. They often synthesize a large number of primary sources that would be difficult and time-consuming to gather by yourself. They allow you to:

• Gain background information on the topic
• Support or contrast your arguments with other researchers’ ideas
• Gather information from primary sources that you can’t access directly (e.g. private letters or physical documents located elsewhere)

When you conduct a literature review or meta analysis, you can consult secondary sources to gain a thorough overview of your topic. If you want to mention a paper or study that you find cited in a secondary source, seek out the original source and cite it directly.

Remember that all primary and secondary sources must be cited to avoid plagiarism . You can use Scribbr’s free citation generator to do so!

Common examples of primary sources include interview transcripts , photographs, novels, paintings, films, historical documents, and official statistics.

Anything you directly analyze or use as first-hand evidence can be a primary source, including qualitative or quantitative data that you collected yourself.

Common examples of secondary sources include academic books, journal articles , reviews, essays , and textbooks.

Anything that summarizes, evaluates or interprets primary sources can be a secondary source. If a source gives you an overview of background information or presents another researcher’s ideas on your topic, it is probably a secondary source.

To determine if a source is primary or secondary, ask yourself:

• Was the source created by someone directly involved in the events you’re studying (primary), or by another researcher (secondary)?
• Does the source provide original information (primary), or does it summarize information from other sources (secondary)?
• Are you directly analyzing the source itself (primary), or only using it for background information (secondary)?

Some types of source are nearly always primary: works of art and literature, raw statistical data, official documents and records, and personal communications (e.g. letters, interviews ). If you use one of these in your research, it is probably a primary source.

Primary sources are often considered the most credible in terms of providing evidence for your argument, as they give you direct evidence of what you are researching. However, it’s up to you to ensure the information they provide is reliable and accurate.

Always make sure to properly cite your sources to avoid plagiarism .

A fictional movie is usually a primary source. A documentary can be either primary or secondary depending on the context.

If you are directly analyzing some aspect of the movie itself – for example, the cinematography, narrative techniques, or social context – the movie is a primary source.

If you use the movie for background information or analysis about your topic – for example, to learn about a historical event or a scientific discovery – the movie is a secondary source.

Whether it’s primary or secondary, always properly cite the movie in the citation style you are using. Learn how to create an MLA movie citation or an APA movie citation .

Articles in newspapers and magazines can be primary or secondary depending on the focus of your research.

In historical studies, old articles are used as primary sources that give direct evidence about the time period. In social and communication studies, articles are used as primary sources to analyze language and social relations (for example, by conducting content analysis or discourse analysis ).

If you are not analyzing the article itself, but only using it for background information or facts about your topic, then the article is a secondary source.

Identifying Research Articles

Research articles are usually fairly easy to distinguish because they follow a standard format. To identify a research article, look for the following components or variations of them:

• Introduction
• Materials and Methods

Articles usually present data in tables or graphs. Reading the article's abstract should also help you to determine whether the article is a research article.

When searching databases for research articles, your first step should be to limit your articles to peer reviewed or refereed journals. Doing this will eliminate any magazine or newspaper articles. When you find an article, read the abstract and look for the following words or variations of them: study, survey, measure, data, statistical, experiment, research.

Some databases allow you to limit your research specifically to research. For example, when refining a search in the CINAHL database, under Publication Type you can limit your results to Research

Finding Research Articles

Search for research articles using science-specific databases, such as the following:

• PsycINFO This link opens in a new window PsycINFO contains citations and summaries of journal articles, book chapters, books, technical reports, and dissertations. Subject: Psychology.
• ScienceDirect This link opens in a new window Set article type to "Research articles" to find primary source articles.
• CINAHL Complete This link opens in a new window Search for primary research articles related to nursing and allied health.
• MEDLINE with Full Text (EBSCO) This link opens in a new window Search for primary research articles in biomedical subjects.
• Academic Search Complete This link opens in a new window This database includes research articles from all subjects, including science.
• GreenFILE This link opens in a new window Search for primary research articles related to environmental science.

Searching the Internet for Scholarly Research Articles

Google Scholar can help when you're searching for hard-to-find information on very specific topics. It includes only academic sources, but not much of it is available in full text for free. It can be a useful tool for identifying articles on your topic that may be available through the Douglas College library or interlibrary loan.
