While there might be many reasons for conducting a literature review, following are four key outcomes of doing the review.

Assessment of the current state of research on a topic . This is probably the most obvious value of the literature review. Once a researcher has determined an area to work with for a research project, a search of relevant information sources will help determine what is already known about the topic and how extensively the topic has already been researched.

Identification of the experts on a particular topic . One of the additional benefits derived from doing the literature review is that it will quickly reveal which researchers have written the most on a particular topic and are, therefore, probably the experts on the topic. Someone who has written twenty articles on a topic or on related topics is more than likely more knowledgeable than someone who has written a single article. This same writer will likely turn up as a reference in most of the other articles written on the same topic. From the number of articles written by the author and the number of times the writer has been cited by other authors, a researcher will be able to assume that the particular author is an expert in the area and, thus, a key resource for consultation in the current research to be undertaken.

Identification of key questions about a topic that need further research . In many cases a researcher may discover new angles that need further exploration by reviewing what has already been written on a topic. For example, research may suggest that listening to music while studying might lead to better retention of ideas, but the research might not have assessed whether a particular style of music is more beneficial than another. A researcher who is interested in pursuing this topic would then do well to follow up existing studies with a new study, based on previous research, that tries to identify which styles of music are most beneficial to retention.

Determination of methodologies used in past studies of the same or similar topics.  It is often useful to review the types of studies that previous researchers have launched as a means of determining what approaches might be of most benefit in further developing a topic. By the same token, a review of previously conducted studies might lend itself to researchers determining a new angle for approaching research.

Upon completion of the literature review, a researcher should have a solid foundation of knowledge in the area and a good feel for the direction any new research should take. Should any additional questions arise during the course of the research, the researcher will know which experts to consult in order to quickly clear up those questions.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

• Provide a comprehensive and updated review of the literature;
• Explain why this review has taken place;
• Articulate a position or hypothesis;
• Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

• Demonstrate how a study fills a gap in research
• Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

• Organizes or describes a topic
• Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

• It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
• It may be too focused. Some niche studies may miss the bigger picture.
• It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
• It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

• 23rd October 2023

If you’re writing a research paper or dissertation , then you’ll most likely need to include a comprehensive literature review . In this post, we’ll review the purpose of literature reviews, why they are so significant, and the specific elements to include in one. Literature reviews can:

1. Provide a foundation for current research.

2. Define key concepts and theories.

3. Demonstrate critical evaluation.

4. Show how research and methodologies have evolved.

5. Identify gaps in existing research.

6. Support your argument.

Keep reading to enter the exciting world of literature reviews!

What is a Literature Review?

A literature review is a critical summary and evaluation of the existing research (e.g., academic journal articles and books) on a specific topic. It is typically included as a separate section or chapter of a research paper or dissertation, serving as a contextual framework for a study. Literature reviews can vary in length depending on the subject and nature of the study, with most being about equal length to other sections or chapters included in the paper. Essentially, the literature review highlights previous studies in the context of your research and summarizes your insights in a structured, organized format. Next, let’s look at the overall purpose of a literature review.

Literature reviews are considered an integral part of research across most academic subjects and fields. The primary purpose of a literature review in your study is to:

Provide a Foundation for Current Research

Since the literature review provides a comprehensive evaluation of the existing research, it serves as a solid foundation for your current study. It’s a way to contextualize your work and show how your research fits into the broader landscape of your specific area of study.  

Define Key Concepts and Theories

The literature review highlights the central theories and concepts that have arisen from previous research on your chosen topic. It gives your readers a more thorough understanding of the background of your study and why your research is particularly significant .

Demonstrate Critical Evaluation 

A comprehensive literature review shows your ability to critically analyze and evaluate a broad range of source material. And since you’re considering and acknowledging the contribution of key scholars alongside your own, it establishes your own credibility and knowledge.

Show How Research and Methodologies Have Evolved

Another purpose of literature reviews is to provide a historical perspective and demonstrate how research and methodologies have changed over time, especially as data collection methods and technology have advanced. And studying past methodologies allows you, as the researcher, to understand what did and did not work and apply that knowledge to your own research.  

Identify Gaps in Existing Research

Besides discussing current research and methodologies, the literature review should also address areas that are lacking in the existing literature. This helps further demonstrate the relevance of your own research by explaining why your study is necessary to fill the gaps.

Support Your Argument

A good literature review should provide evidence that supports your research questions and hypothesis. For example, your study may show that your research supports existing theories or builds on them in some way. Referencing previous related studies shows your work is grounded in established research and will ultimately be a contribution to the field.

• Citation: "The Literature Review: A Few Tips on Conducting it"

What kinds of literature reviews are written?

Each field has a particular way to do reviews for academic research literature. In the social sciences and humanities the most common are:

• Narrative Reviews: The purpose of this type of review is to describe the current state of the research on a specific research topic and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weaknesses, and gaps are identified. The review ends with a conclusion section that summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.
• Book review essays/ Historiographical review essays : A type of literature review typical in History and related fields, e.g., Latin American studies. For example, the Latin American Research Review explains that the purpose of this type of review is to “(1) to familiarize readers with the subject, approach, arguments, and conclusions found in a group of books whose common focus is a historical period; a country or region within Latin America; or a practice, development, or issue of interest to specialists and others; (2) to locate these books within current scholarship, critical methodologies, and approaches; and (3) to probe the relation of these new books to previous work on the subject, especially canonical texts. Unlike individual book reviews, the cluster reviews found in LARR seek to address the state of the field or discipline and not solely the works at issue.” - LARR

What are the Goals of Creating a Literature Review?

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 
• Baumeister, R.F. & Leary, M.R. (1997). "Writing narrative literature reviews," Review of General Psychology , 1(3), 311-320.

When do you need to write a Literature Review?

• When writing a prospectus or a thesis/dissertation
• When writing a research paper
• When writing a grant proposal

In all these cases you need to dedicate a chapter in these works to showcase what has been written about your research topic and to point out how your own research will shed new light into a body of scholarship.

Where I can find examples of Literature Reviews?

Note:  In the humanities, even if they don't use the term "literature review", they may have a dedicated  chapter that reviewed the "critical bibliography" or they incorporated that review in the introduction or first chapter of the dissertation, book, or article.

• UCSB electronic theses and dissertations In partnership with the Graduate Division, the UC Santa Barbara Library is making available theses and dissertations produced by UCSB students. Currently included in ADRL are theses and dissertations that were originally filed electronically, starting in 2011. In future phases of ADRL, all theses and dissertations created by UCSB students may be digitized and made available.

Where to Find Standalone Literature Reviews

Literature reviews are also written as standalone articles as a way to survey a particular research topic in-depth. This type of literature review looks at a topic from a historical perspective to see how the understanding of the topic has changed over time. 

• Find e-Journals for Standalone Literature Reviews The best way to get familiar with and to learn how to write literature reviews is by reading them. You can use our Journal Search option to find journals that specialize in publishing literature reviews from major disciplines like anthropology, sociology, etc. Usually these titles are called, "Annual Review of [discipline name] OR [Discipline name] Review. This option works best if you know the title of the publication you are looking for. Below are some examples of these journals! more... less...

Library Guide to Capstone Literature Reviews: Role of the Literature Review

The role of the literature review.

Your literature review gives readers an understanding of the scholarly research on your topic.

In your literature review you will:

• demonstrate that you are a well-informed scholar with expertise and knowledge in the field by giving an overview of the current state of the literature
• find a gap in the literature, or address a business or professional issue, depending on your doctoral study program; the literature review will illustrate how your research contributes to the scholarly conversation
• provide a synthesis of the issues, trends, and concepts surrounding your research

Be aware that the literature review is an iterative process. As you read and write initial drafts, you will find new threads and complementary themes, at which point you will return to search, find out about these new themes, and incorporate them into your review.

The purpose of this guide is to help you through the literature review process. Take some time to look over the resources in order to become familiar with them. The tabs on the left side of this page have additional information.

Literature review as a dinner party

To think about the role of the literature review, consider this analogy:  pretend that you throw a dinner party for the other researchers working in your topic area. First, you’d need to develop a guest list.

• The guests of honor would be early researchers or theorists; their work likely inspired subsequent studies, ideas, or controversies that the current researchers pursue.
• Then, think about the important current researchers to invite. Which guests might agree with each other?  Which others might provide useful counterpoints?
• You likely won’t be able to include everyone on the guest list, so you may need to choose carefully so that you don’t leave important figures out. 
• Alternatively, if there aren’t many researchers working in your topic area, then your guest list will need to include people working in other, related areas, who can still contribute to the conversation.

After the party, you describe the evening to a friend. You’ll summarize the evening’s conversation. Perhaps one guest made a comment that sparked a conversation, and then you describe who responded and how the topic evolved. There are other conversations to share, too. This is how you synthesize the themes and developments that you find in your research. Thinking about your literature research this way will help you to present your dinner party (and your literature review) in a lively and engaging way.

The Literature Review: A Foundation for High-Quality Medical Education Research

a  These are subscription resources. Researchers should check with their librarian to determine their access rights.

Despite a surge in published scholarship in medical education 1 and rapid growth in journals that publish educational research, manuscript acceptance rates continue to fall. 2 Failure to conduct a thorough, accurate, and up-to-date literature review identifying an important problem and placing the study in context is consistently identified as one of the top reasons for rejection. 3 , 4 The purpose of this editorial is to provide a road map and practical recommendations for planning a literature review. By understanding the goals of a literature review and following a few basic processes, authors can enhance both the quality of their educational research and the likelihood of publication in the Journal of Graduate Medical Education ( JGME ) and in other journals.

The Literature Review Defined

In medical education, no organization has articulated a formal definition of a literature review for a research paper; thus, a literature review can take a number of forms. Depending on the type of article, target journal, and specific topic, these forms will vary in methodology, rigor, and depth. Several organizations have published guidelines for conducting an intensive literature search intended for formal systematic reviews, both broadly (eg, PRISMA) 5 and within medical education, 6 and there are excellent commentaries to guide authors of systematic reviews. 7 , 8

• A literature review forms the basis for high-quality medical education research and helps maximize relevance, originality, generalizability, and impact.
• A literature review provides context, informs methodology, maximizes innovation, avoids duplicative research, and ensures that professional standards are met.
• Literature reviews take time, are iterative, and should continue throughout the research process.
• Researchers should maximize the use of human resources (librarians, colleagues), search tools (databases/search engines), and existing literature (related articles).
• Keeping organized is critical.

Such work is outside the scope of this article, which focuses on literature reviews to inform reports of original medical education research. We define such a literature review as a synthetic review and summary of what is known and unknown regarding the topic of a scholarly body of work, including the current work's place within the existing knowledge . While this type of literature review may not require the intensive search processes mandated by systematic reviews, it merits a thoughtful and rigorous approach.

Purpose and Importance of the Literature Review

An understanding of the current literature is critical for all phases of a research study. Lingard 9 recently invoked the “journal-as-conversation” metaphor as a way of understanding how one's research fits into the larger medical education conversation. As she described it: “Imagine yourself joining a conversation at a social event. After you hang about eavesdropping to get the drift of what's being said (the conversational equivalent of the literature review), you join the conversation with a contribution that signals your shared interest in the topic, your knowledge of what's already been said, and your intention.” 9

The literature review helps any researcher “join the conversation” by providing context, informing methodology, identifying innovation, minimizing duplicative research, and ensuring that professional standards are met. Understanding the current literature also promotes scholarship, as proposed by Boyer, 10 by contributing to 5 of the 6 standards by which scholarly work should be evaluated. 11 Specifically, the review helps the researcher (1) articulate clear goals, (2) show evidence of adequate preparation, (3) select appropriate methods, (4) communicate relevant results, and (5) engage in reflective critique.

Failure to conduct a high-quality literature review is associated with several problems identified in the medical education literature, including studies that are repetitive, not grounded in theory, methodologically weak, and fail to expand knowledge beyond a single setting. 12 Indeed, medical education scholars complain that many studies repeat work already published and contribute little new knowledge—a likely cause of which is failure to conduct a proper literature review. 3 , 4

Likewise, studies that lack theoretical grounding or a conceptual framework make study design and interpretation difficult. 13 When theory is used in medical education studies, it is often invoked at a superficial level. As Norman 14 noted, when theory is used appropriately, it helps articulate variables that might be linked together and why, and it allows the researcher to make hypotheses and define a study's context and scope. Ultimately, a proper literature review is a first critical step toward identifying relevant conceptual frameworks.

Another problem is that many medical education studies are methodologically weak. 12 Good research requires trained investigators who can articulate relevant research questions, operationally define variables of interest, and choose the best method for specific research questions. Conducting a proper literature review helps both novice and experienced researchers select rigorous research methodologies.

Finally, many studies in medical education are “one-offs,” that is, single studies undertaken because the opportunity presented itself locally. Such studies frequently are not oriented toward progressive knowledge building and generalization to other settings. A firm grasp of the literature can encourage a programmatic approach to research.

Approaching the Literature Review

Considering these issues, journals have a responsibility to demand from authors a thoughtful synthesis of their study's position within the field, and it is the authors' responsibility to provide such a synthesis, based on a literature review. The aforementioned purposes of the literature review mandate that the review occurs throughout all phases of a study, from conception and design, to implementation and analysis, to manuscript preparation and submission.

Planning the literature review requires understanding of journal requirements, which vary greatly by journal ( table 1 ). Authors are advised to take note of common problems with reporting results of the literature review. Table 2 lists the most common problems that we have encountered as authors, reviewers, and editors.

Common Problem Areas for Reporting Literature Reviews in the Context of Scholarly Articles

Locating and Organizing the Literature

Three resources may facilitate identifying relevant literature: human resources, search tools, and related literature. As the process requires time, it is important to begin searching for literature early in the process (ie, the study design phase). Identifying and understanding relevant studies will increase the likelihood of designing a relevant, adaptable, generalizable, and novel study that is based on educational or learning theory and can maximize impact.

Human Resources

A medical librarian can help translate research interests into an effective search strategy, familiarize researchers with available information resources, provide information on organizing information, and introduce strategies for keeping current with emerging research. Often, librarians are also aware of research across their institutions and may be able to connect researchers with similar interests. Reaching out to colleagues for suggestions may help researchers quickly locate resources that would not otherwise be on their radar.

During this process, researchers will likely identify other researchers writing on aspects of their topic. Researchers should consider searching for the publications of these relevant researchers (see table 3 for search strategies). Additionally, institutional websites may include curriculum vitae of such relevant faculty with access to their entire publication record, including difficult to locate publications, such as book chapters, dissertations, and technical reports.

Strategies for Finding Related Researcher Publications in Databases and Search Engines

Search Tools and Related Literature

Researchers will locate the majority of needed information using databases and search engines. Excellent resources are available to guide researchers in the mechanics of literature searches. 15 , 16

Because medical education research draws on a variety of disciplines, researchers should include search tools with coverage beyond medicine (eg, psychology, nursing, education, and anthropology) and that cover several publication types, such as reports, standards, conference abstracts, and book chapters (see the box for several information resources). Many search tools include options for viewing citations of selected articles. Examining cited references provides additional articles for review and a sense of the influence of the selected article on its field.

Box Information Resources

• Web of Science a
• Education Resource Information Center (ERIC)
• Cumulative Index of Nursing & Allied Health (CINAHL) a
• Google Scholar

Once relevant articles are located, it is useful to mine those articles for additional citations. One strategy is to examine references of key articles, especially review articles, for relevant citations.

Getting Organized

As the aforementioned resources will likely provide a tremendous amount of information, organization is crucial. Researchers should determine which details are most important to their study (eg, participants, setting, methods, and outcomes) and generate a strategy for keeping those details organized and accessible. Increasingly, researchers utilize digital tools, such as Evernote, to capture such information, which enables accessibility across digital workspaces and search capabilities. Use of citation managers can also be helpful as they store citations and, in some cases, can generate bibliographies ( table 4 ).

Citation Managers

Knowing When to Say When

Researchers often ask how to know when they have located enough citations. Unfortunately, there is no magic or ideal number of citations to collect. One strategy for checking coverage of the literature is to inspect references of relevant articles. As researchers review references they will start noticing a repetition of the same articles with few new articles appearing. This can indicate that the researcher has covered the literature base on a particular topic.

Putting It All Together

In preparing to write a research paper, it is important to consider which citations to include and how they will inform the introduction and discussion sections. The “Instructions to Authors” for the targeted journal will often provide guidance on structuring the literature review (or introduction) and the number of total citations permitted for each article category. Reviewing articles of similar type published in the targeted journal can also provide guidance regarding structure and average lengths of the introduction and discussion sections.

When selecting references for the introduction consider those that illustrate core background theoretical and methodological concepts, as well as recent relevant studies. The introduction should be brief and present references not as a laundry list or narrative of available literature, but rather as a synthesized summary to provide context for the current study and to identify the gap in the literature that the study intends to fill. For the discussion, citations should be thoughtfully selected to compare and contrast the present study's findings with the current literature and to indicate how the present study moves the field forward.

To facilitate writing a literature review, journals are increasingly providing helpful features to guide authors. For example, the resources available through JGME include several articles on writing. 17 The journal Perspectives on Medical Education recently launched “The Writer's Craft,” which is intended to help medical educators improve their writing. Additionally, many institutions have writing centers that provide web-based materials on writing a literature review, and some even have writing coaches.

The literature review is a vital part of medical education research and should occur throughout the research process to help researchers design a strong study and effectively communicate study results and importance. To achieve these goals, researchers are advised to plan and execute the literature review carefully. The guidance in this editorial provides considerations and recommendations that may improve the quality of literature reviews.

The purpose of a literature review is to collect relevant, timely research on your chosen topic, and synthesize it into a cohesive summary of existing knowledge in the field. This then prepares you for making your own argument on that topic, or for conducting your own original research.

Depending on your field of study, literature reviews can take different forms. Some disciplines require that you synthesize your sources topically, organizing your paragraphs according to how your different sources discuss similar topics. Other disciplines require that you discuss each source in individual paragraphs, covering various aspects in that single article, chapter, or book.

Within your review of a given source, you can cover many different aspects, including (if a research study) the purpose, scope, methods, results, any discussion points, limitations, and implications for future research. Make sure you know which model your professor expects you to follow when writing your own literature reviews.

Tip : Literature reviews may or may not be a graded component of your class or major assignment, but even if it is not, it is a good idea to draft one so that you know the current conversations taking place on your chosen topic. It can better prepare you to write your own, unique argument.

Benefits of Literature Reviews

• Literature reviews allow you to gain familiarity with the current knowledge in your chosen field, as well as the boundaries and limitations of that field.
• Literature reviews also help you to gain an understanding of the theory(ies) driving the field, allowing you to place your research question into context.
• Literature reviews provide an opportunity for you to see and even evaluate successful and unsuccessful assessment and research methods in your field.
• Literature reviews prevent you from duplicating the same information as others writing in your field, allowing you to find your own, unique approach to your topic.
• Literature reviews give you familiarity with the knowledge in your field, giving you the chance to analyze the significance of your additional research.

Choosing Your Sources

When selecting your sources to compile your literature review, make sure you follow these guidelines to ensure you are working with the strongest, most appropriate sources possible.

Topically Relevant

Find sources within the scope of your topic

Appropriately Aged

Find sources that are not too old for your assignment

Find sources whose authors have authority on your topic

Appropriately “Published”

Find sources that meet your instructor’s guidelines (academic, professional, print, etc.)

Tip:  Treat your professors and librarians as experts you can turn to for advice on how to locate sources. They are a valuable asset to you, so take advantage of them!

Organizing Your Literature Review

Synthesizing topically.

Some assignments require discussing your sources together, in paragraphs organized according to shared topics between them.

For example, in a literature review covering current conversations on Alison Bechdel’s  Fun Home , authors may discuss various topics including:

• her graphic style
• her allusions to various literary texts
• her story’s implications regarding LGBT experiences in 20 th  century America.

In this case, you would cluster your sources on these three topics. One paragraph would cover how the sources you collected dealt with Bechdel’s graphic style. Another, her allusions. A third, her implications.

Each of these paragraphs would discuss how the sources you found treated these topics in connection to one another. Basically, you compare and contrast how your sources discuss similar issues and points.

To determine these shared topics, examine aspects including:

• Definition of terms
• Common ground
• Issues that divide
• Rhetorical context

Summarizing Individually

Depending on the assignment, your professor may prefer that you discuss each source in your literature review individually (in their own, separate paragraphs or sections). Your professor may give you specific guidelines as far as what to cover in these paragraphs/sections.

If, for instance, your sources are all primary research studies, here are some aspects to consider covering:

• Participants
• Limitations
• Implications
• Significance

Each section of your literature review, in this case, will identify all of these elements for each individual article.

You may or may not need to separate your information into multiple paragraphs for each source. If you do, using proper headings in the appropriate citation style (APA, MLA, etc.) will help keep you organized.

If you are writing a literature review as part of a larger assignment, you generally do not need an introduction and/or conclusion, because it is embedded within the context of your larger paper.

If, however, your literature review is a standalone assignment, it is a good idea to include some sort of introduction and conclusion to provide your reader with context regarding your topic, purpose, and any relevant implications or further questions. Make sure you know what your professor is expecting for your literature review’s content.

Typically, a literature review concludes with a full bibliography of your included sources. Make sure you use the style guide required by your professor for this assignment.

Questions to Consider

B. In some fields or contexts, a literature review is referred to as the introduction or the background; why is this true, and does it matter?

The elements of a literature review • The first step in scholarly research is determining the “state of the art” on a topic. This is accomplished by gathering academic research and making sense of it. • The academic literature can be found in scholarly books and journals; the goal is to discover recurring themes, find the latest data, and identify any missing pieces. • The resulting literature review organizes the research in such a way that tells a story about the topic or issue.

The literature review tells a story in which one well-paraphrased summary from a relevant source contributes to and connects with the next in a logical manner, developing and fulfilling the message of the author. It includes analysis of the arguments from the literature, as well as revealing consistent and inconsistent findings. How do varying author insights differ from or conform to previous arguments?

Language in Action

A. How are the terms “critique” and “review” used in everyday life? How are they used in an academic context?

In terms of content, a literature review is intended to:

• Set up a theoretical framework for further research • Show a clear understanding of the key concepts/studies/models related to the topic • Demonstrate knowledge about the history of the research area and any related controversies • Clarify significant definitions and terminology • Develop a space in the existing work for new research

The literature consists of the published works that document a scholarly conversation or progression on a problem or topic in a field of study. Among these are documents that explain the background and show the loose ends in the established research on which a proposed project is based. Although a literature review focuses on primary, peer -reviewed resources, it may begin with background subject information generally found in secondary and tertiary sources such as books and encyclopedias. Following that essential overview, the seminal literature of the field is explored. As a result, while a literature review may consist of research articles tightly focused on a topic with secondary and tertiary sources used more sparingly, all three types of information (primary, secondary, tertiary) are critical.

The literature review, often referred to as the Background or Introduction to a research paper that presents methods, materials, results and discussion, exists in every field and serves many functions in research writing.

Conducting your literature review 

by Susanne Hempel

The purpose of a literature review

Conducting a literature review is a means of demonstrating the  author’s knowledge  about a particular field of study, including vocabulary, theories, key variables and phenomena, and its methods and history. Conducting a literature review also informs the student of the  influential researchers and research groups  in the field (Randolph, 2009).

Literature reviews:

• report on  knowledge and ideas  that have been established on a particular topic, including their  strengths and weaknesses  while they allow you to discover the agreed academic opinion on the topic while at the same time letting you find out the disagreements on the same subject.
• position your research project within the body of literature and thereby  provide perspective  for the reader.
• demonstrate  your knowledge  of the subject area.
• determine what each source contributes to the topic.
• understand the  relationship between the various contributions , identify and (if possible) resolve contradictions, and determine gaps or unanswered questions.
• justify your  choice of research design ; for instance, your choice of qualitative over quantitative approaches, or your method of data analysis.
• clarify how your work fills a  gap  in the scholarly literature.

Writing a literature review also allows you to:

• gain expertise in the ability to scan the literature on a particular topic efficiently, and
• hone your skills in identifying and analysing unbiased and valid data on various topics or fields of study.

Research on research? If you find this idea rather peculiar, know that nowadays, with the huge amount of information produced daily all around the world, it is becoming more and more difficult to keep up to date with all of it. In addition to the sheer amount of research, there is also its origin. We are witnessing the economic and intellectual emergence of countries like China, Brazil, Turkey, and United Arab Emirates, for example, that are producing scholarly literature in their own languages. So, apart from the effort of gathering information, there must also be translators prepared to unify all of it in a single language to be the object of the literature survey. At Elsevier, our team of translators is ready to support researchers by delivering high-quality scientific translations , in several languages, to serve their research – no matter the topic.

What is a literature review?

A literature review is a study – or, more accurately, a survey – involving scholarly material, with the aim to discuss published information about a specific topic or research question. Therefore, to write a literature review, it is compulsory that you are a real expert in the object of study. The results and findings will be published and made available to the public, namely scientists working in the same area of research.

How to Write a Literature Review

First of all, don’t forget that writing a literature review is a great responsibility. It’s a document that is expected to be highly reliable, especially concerning its sources and findings. You have to feel intellectually comfortable in the area of study and highly proficient in the target language; misconceptions and errors do not have a place in a document as important as a literature review. In fact, you might want to consider text editing services, like those offered at Elsevier, to make sure your literature is following the highest standards of text quality. You want to make sure your literature review is memorable by its novelty and quality rather than language errors.

Writing a literature review requires expertise but also organization. We cannot teach you about your topic of research, but we can provide a few steps to guide you through conducting a literature review:

• Choose your topic or research question: It should not be too comprehensive or too limited. You have to complete your task within a feasible time frame.
• Set the scope: Define boundaries concerning the number of sources, time frame to be covered, geographical area, etc.
• Decide which databases you will use for your searches: In order to search the best viable sources for your literature review, use highly regarded, comprehensive databases to get a big picture of the literature related to your topic.
• Search, search, and search: Now you’ll start to investigate the research on your topic. It’s critical that you keep track of all the sources. Start by looking at research abstracts in detail to see if their respective studies relate to or are useful for your own work. Next, search for bibliographies and references that can help you broaden your list of resources. Choose the most relevant literature and remember to keep notes of their bibliographic references to be used later on.
• Review all the literature, appraising carefully it’s content: After reading the study’s abstract, pay attention to the rest of the content of the articles you deem the “most relevant.” Identify methodologies, the most important questions they address, if they are well-designed and executed, and if they are cited enough, etc.

If it’s the first time you’ve published a literature review, note that it is important to follow a special structure. Just like in a thesis, for example, it is expected that you have an introduction – giving the general idea of the central topic and organizational pattern – a body – which contains the actual discussion of the sources – and finally the conclusion or recommendations – where you bring forward whatever you have drawn from the reviewed literature. The conclusion may even suggest there are no agreeable findings and that the discussion should be continued.

Why are literature reviews important?

Literature reviews constantly feed new research, that constantly feeds literature reviews…and we could go on and on. The fact is, one acts like a force over the other and this is what makes science, as a global discipline, constantly develop and evolve. As a scientist, writing a literature review can be very beneficial to your career, and set you apart from the expert elite in your field of interest. But it also can be an overwhelming task, so don’t hesitate in contacting Elsevier for text editing services, either for profound edition or just a last revision. We guarantee the very highest standards. You can also save time by letting us suggest and make the necessary amendments to your manuscript, so that it fits the structural pattern of a literature review. Who knows how many worldwide researchers you will impact with your next perfectly written literature review.

The Research Proposal

83 Components of the Literature Review

Krathwohl (2005) suggests and describes a variety of components to include in a research proposal.  The following sections present these components in a suggested template for you to follow in the preparation of your research proposal.

Introduction

The introduction sets the tone for what follows in your research proposal – treat it as the initial pitch of your idea.  After reading the introduction your reader should:

• Understand what it is you want to do;
• Have a sense of your passion for the topic;
• Be excited about the study´s possible outcomes.

As you begin writing your research proposal it is helpful to think of the introduction as a narrative of what it is you want to do, written in one to three paragraphs.  Within those one to three paragraphs, it is important to briefly answer the following questions:

• What is the central research problem?
• How is the topic of your research proposal related to the problem?
• What methods will you utilize to analyze the research problem?
• Why is it important to undertake this research? What is the significance of your proposed research?  Why are the outcomes of your proposed research important, and to whom or to what are they important?

Note : You may be asked by your instructor to include an abstract with your research proposal.  In such cases, an abstract should provide an overview of what it is you plan to study, your main research question, a brief explanation of your methods to answer the research question, and your expected findings. All of this information must be carefully crafted in 150 to 250 words.  A word of advice is to save the writing of your abstract until the very end of your research proposal preparation.  If you are asked to provide an abstract, you should include 5-7 key words that are of most relevance to your study. List these in order of relevance.

Background and significance

The purpose of this section is to explain the context of your proposal and to describe, in detail, why it is important to undertake this research. Assume that the person or people who will read your research proposal know nothing or very little about the research problem.  While you do not need to include all knowledge you have learned about your topic in this section, it is important to ensure that you include the most relevant material that will help to explain the goals of your research.

While there are no hard and fast rules, you should attempt to address some or all of the following key points:

• State the research problem and provide a more thorough explanation about the purpose of the study than what you stated in the introduction.
• Present the rationale for the proposed research study. Clearly indicate why this research is worth doing.  Answer the “so what?” question.
• Describe the major issues or problems to be addressed by your research. Do not forget to explain how and in what ways your proposed research builds upon previous related research.
• Explain how you plan to go about conducting your research.
• Clearly identify the key or most relevant sources of research you intend to use and explain how they will contribute to your analysis of the topic.
• Set the boundaries of your proposed research, in order to provide a clear focus. Where appropriate, state not only what you will study, but what will be excluded from your study.
• Provide clear definitions of key concepts and terms. As key concepts and terms often have numerous definitions, make sure you state which definition you will be utilizing in your research.

Literature Review

This is the most time-consuming aspect in the preparation of your research proposal and it is a key component of the research proposal. As described in Chapter 5 , the literature review provides the background to your study and demonstrates the significance of the proposed research. Specifically, it is a review and synthesis of prior research that is related to the problem you are setting forth to investigate.  Essentially, your goal in the literature review is to place your research study within the larger whole of what has been studied in the past, while demonstrating to your reader that your work is original, innovative, and adds to the larger whole.

As the literature review is information dense, it is essential that this section be intelligently structured to enable your reader to grasp the key arguments underpinning your study. However, this can be easier to state and harder to do, simply due to the fact there is usually a plethora of related research to sift through. Consequently, a good strategy for writing the literature review is to break the literature into conceptual categories or themes, rather than attempting to describe various groups of literature you reviewed.  Chapter V, “ The Literature Review ,” describes a variety of methods to help you organize the themes.

Here are some suggestions on how to approach the writing of your literature review:

• Think about what questions other researchers have asked, what methods they used, what they found, and what they recommended based upon their findings.
• Do not be afraid to challenge previous related research findings and/or conclusions.
• Assess what you believe to be missing from previous research and explain how your research fills in this gap and/or extends previous research

It is important to note that a significant challenge related to undertaking a literature review is knowing when to stop.  As such, it is important to know how to know when you have uncovered the key conceptual categories underlying your research topic.  Generally, when you start to see repetition in the conclusions or recommendations, you can have confidence that you have covered all of the significant conceptual categories in your literature review.  However, it is also important to acknowledge that researchers often find themselves returning to the literature as they collect and analyze their data.  For example, an unexpected finding may develop as one collects and/or analyzes the data and it is important to take the time to step back and review the literature again, to ensure that no other researchers have found a similar finding.  This may include looking to research outside your field.

This situation occurred with one of the authors of this textbook´s research related to community resilience.  During the interviews, the researchers heard many participants discuss individual resilience factors and how they believed these individual factors helped make the community more resilient, overall.  Sheppard and Williams (2016) had not discovered these individual factors in their original literature review on community and environmental resilience. However, when they returned to the literature to search for individual resilience factors, they discovered a small body of literature in the child and youth psychology field. Consequently, Sheppard and Williams had to go back and add a new section to their literature review on individual resilience factors. Interestingly, their research appeared to be the first research to link individual resilience factors with community resilience factors.

Research design and methods

The objective of this section of the research proposal is to convince the reader that your overall research design and methods of analysis will enable you to solve the research problem you have identified and also enable you to accurately and effectively interpret the results of your research. Consequently, it is critical that the research design and methods section is well-written, clear, and logically organized.  This demonstrates to your reader that you know what you are going to do and how you are going to do it.  Overall, you want to leave your reader feeling confident that you have what it takes to get this research study completed in a timely fashion.

Essentially, this section of the research proposal should be clearly tied to the specific objectives of your study; however, it is also important to draw upon and include examples from the literature review that relate to your design and intended methods.  In other words, you must clearly demonstrate how your study utilizes and builds upon past studies, as it relates to the research design and intended methods.  For example, what methods have been used by other researchers in similar studies?

While it is important to consider the methods that other researchers have employed, it is equally important, if not more so, to consider what methods have not been employed but could be.  Remember, the methods section is not simply a list of tasks to be undertaken. It is also an argument as to why and how the tasks you have outlined will help you investigate the research problem and answer your research question(s).

Tips for writing the research design and methods section:

• Specify the methodological approaches you intend to employ to obtain information and the techniques you will use to analyze the data.
• Specify the research operations you will undertake and he way you will interpret the results of those operations in relation to the research problem.
• Go beyond stating what you hope to achieve through the methods you have chosen. State how you will actually do the methods (i.e. coding interview text, running regression analysis, etc.).
• Anticipate and acknowledge any potential barriers you may encounter when undertaking your research and describe how you will address these barriers.
• Explain where you believe you will find challenges related to data collection, including access to participants and information.

Preliminary suppositions and implications

The purpose of this section is to argue how and in what ways you anticipate that your research will refine, revise, or extend existing knowledge in the area of your study. Depending upon the aims and objectives of your study, you should also discuss how your anticipated findings may impact future research.  For example, is it possible that your research may lead to a new policy, new theoretical understanding, or a new method for analyzing data?  How might your study influence future studies?  What might your study mean for future practitioners working in the field?  Who or what may benefit from your study?  How might your study contribute to social, economic, environmental issues?  While it is important to think about and discuss possibilities such as these, it is equally important to be realistic in stating your anticipated findings.  In other words, you do not want to delve into idle speculation.  Rather, the purpose here is to reflect upon gaps in the current body of literature and to describe how and in what ways you anticipate your research will begin to fill in some or all of those gaps.

The conclusion reiterates the importance and significance of your research proposal and it provides a brief summary of the entire proposed study.  Essentially, this section should only be one or two paragraphs in length. Here is a potential outline for your conclusion:

• Discuss why the study should be done. Specifically discuss how you expect your study will advance existing knowledge and how your study is unique.
• Explain the specific purpose of the study and the research questions that the study will answer.
• Explain why the research design and methods chosen for this study are appropriate, and why other design and methods were not chosen.
• State the potential implications you expect to emerge from your proposed study,
• Provide a sense of how your study fits within the broader scholarship currently in existence related to the research problem.

As with any scholarly research paper, you must cite the sources you used in composing your research proposal.  In a research proposal, this can take two forms: a reference list or a bibliography.  A reference list does what the name suggests, it lists the literature you referenced in the body of your research proposal.  All references in the reference list, must appear in the body of the research proposal.  Remember, it is not acceptable to say “as cited in …”  As a researcher you must always go to the original source and check it for yourself.  Many errors are made in referencing, even by top researchers, and so it is important not to perpetuate an error made by someone else. While this can be time consuming, it is the proper way to undertake a literature review.

In contrast, a bibliography , is a list of everything you used or cited in your research proposal, with additional citations to any key sources relevant to understanding the research problem.  In other words, sources cited in your bibliography may not necessarily appear in the body of your research proposal.  Make sure you check with your instructor to see which of the two you are expected to produce.

Overall, your list of citations should be a testament to the fact that you have done a sufficient level of preliminary research to ensure that your project will complement, but not duplicate, previous research efforts. For social sciences, the reference list or bibliography should be prepared in American Psychological Association (APA) referencing format. Usually, the reference list (or bibliography) is not included in the word count of the research proposal. Again, make sure you check with your instructor to confirm.

Metrics details

This scoping review aimed to identify and present the evidence describing key motivations for breast cancer screening among women aged ≥ 75 years. Few of the internationally available guidelines recommend continued biennial screening for this age group. Some suggest ongoing screening is unnecessary or should be determined on individual health status and life expectancy. Recent research has shown that despite recommendations regarding screening, older women continue to hold positive attitudes to breast screening and participate when the opportunity is available.

All original research articles that address motivation, intention and/or participation in screening for breast cancer among women aged ≥ 75 years were considered for inclusion. These included articles reporting on women who use public and private breast cancer screening services and those who do not use screening services (i.e., non-screeners).

The Joanna Briggs Institute (JBI) methodology for scoping reviews was used to guide this review. A comprehensive search strategy was developed with the assistance of a specialist librarian to access selected databases including: the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Web of Science and PsychInfo. The review was restricted to original research studies published since 2009, available in English and focusing on high-income countries (as defined by the World Bank). Title and abstract screening, followed by an assessment of full-text studies against the inclusion criteria was completed by at least two reviewers. Data relating to key motivations, screening intention and behaviour were extracted, and a thematic analysis of study findings undertaken.

A total of fourteen (14) studies were included in the review. Thematic analysis resulted in identification of three themes from included studies highlighting that decisions about screening were influenced by: knowledge of the benefits and harms of screening and their relationship to age; underlying attitudes to the importance of cancer screening in women's lives; and use of decision aids to improve knowledge and guide decision-making.

The results of this review provide a comprehensive overview of current knowledge regarding the motivations and screening behaviour of older women about breast cancer screening which may inform policy development.

Peer Review reports

Introduction

Breast cancer is now the most commonly diagnosed cancer in the world overtaking lung cancer in 2021 [ 1 ]. Across the globe, breast cancer contributed to 25.8% of the total number of new cases of cancer diagnosed in 2020 [ 2 ] and accounts for a high disease burden for women [ 3 ]. Screening for breast cancer is an effective means of detecting early-stage cancer and has been shown to significantly improve survival rates [ 4 ]. A recent systematic review of international screening guidelines found that most countries recommend that women have biennial mammograms between the ages of 40–70 years [ 5 ] with some recommending that there should be no upper age limit [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ] and others suggesting that benefits of continued screening for women over 75 are not clear [ 13 , 14 , 15 ].

Some guidelines suggest that the decision to end screening should be determined based on the individual health status of the woman, their life expectancy and current health issues [ 5 , 16 , 17 ]. This is because the benefits of mammography screening may be limited after 7 years due to existing comorbidities and limited life expectancy [ 18 , 19 , 20 , 21 ], with some jurisdictions recommending breast cancer screening for women ≥ 75 years only when life expectancy is estimated as at least 7–10 years [ 22 ]. Others have argued that decisions about continuing with screening mammography should depend on individual patient risk and health management preferences [ 23 ]. This decision is likely facilitated by a discussion between a health care provider and patient about the harms and benefits of screening outside the recommended ages [ 24 , 25 ]. While mammography may enable early detection of breast cancer, it is clear that false-positive results and overdiagnosis Footnote 1 may occur. Studies have estimated that up to 25% of breast cancer cases in the general population may be over diagnosed [ 26 , 27 , 28 ].

The risk of being diagnosed with breast cancer increases with age and approximately 80% of new cases of breast cancer in high-income countries are in women over the age of 50 [ 29 ]. The average age of first diagnosis of breast cancer in high income countries is comparable to that of Australian women which is now 61 years [ 2 , 4 , 29 ]. Studies show that women aged ≥ 75 years generally have positive attitudes to mammography screening and report high levels of perceived benefits including early detection of breast cancer and a desire to stay healthy as they age [ 21 , 30 , 31 , 32 ]. Some women aged over 74 participate, or plan to participate, in screening despite recommendations from health professionals and government guidelines advising against it [ 33 ]. Results of a recent review found that knowledge of the recommended guidelines and the potential harms of screening are limited and many older women believed that the benefits of continued screening outweighed the risks [ 30 ].

Very few studies have been undertaken to understand the motivations of women to screen or to establish screening participation rates among women aged ≥ 75 and older. This is surprising given that increasing age is recognised as a key risk factor for the development of breast cancer, and that screening is offered in many locations around the world every two years up until 74 years. The importance of this topic is high given the ambiguity around best practice for participation beyond 74 years. A preliminary search of Open Science Framework, PROSPERO, Cochrane Database of Systematic Reviews and JBI Evidence Synthesis in May 2022 did not locate any reviews on this topic.

This scoping review has allowed for the mapping of a broad range of research to explore the breadth and depth of the literature, summarize the evidence and identify knowledge gaps [ 34 , 35 ]. This information has supported the development of a comprehensive overview of current knowledge of motivations of women to screen and screening participation rates among women outside the targeted age of many international screening programs.

Materials and methods

Research question.

The research question for this scoping review was developed by applying the Population—Concept—Context (PCC) framework [ 36 ]. The current review addresses the research question “What research has been undertaken in high-income countries (context) exploring the key motivations to screen for breast cancer and screening participation (concepts) among women ≥ 75 years of age (population)?

Eligibility criteria

Participants.

Women aged ≥ 75 years were the key population. Specifically, motivations to screen and screening intention and behaviour and the variables that discriminate those who screen from those who do not (non-screeners) were utilised as the key predictors and outcomes respectively.

From a conceptual perspective it was considered that motivation led to behaviour, therefore articles that described motivation and corresponding behaviour were considered. These included articles reporting on women who use public (government funded) and private (fee for service) breast cancer screening services and those who do not use screening services (i.e., non-screeners).

The scope included high-income countries using the World Bank definition [ 37 ]. These countries have broadly similar health systems and opportunities for breast cancer screening in both public and private settings.

Types of sources

All studies reporting original research in peer-reviewed journals from January 2009 were eligible for inclusion, regardless of design. This date was selected due to an evaluation undertaken for BreastScreen Australia recommending expansion of the age group to include 70–74-year-old women [ 38 ]. This date was also indicative of international debate regarding breast cancer screening effectiveness at this time [ 39 , 40 ]. Reviews were also included, regardless of type—scoping, systematic, or narrative. Only sources published in English and available through the University’s extensive research holdings were eligible for inclusion. Ineligible materials were conference abstracts, letters to the editor, editorials, opinion pieces, commentaries, newspaper articles, dissertations and theses.

This scoping review was registered with the Open Science Framework database ( https://osf.io/fd3eh ) and followed Joanna Briggs Institute (JBI) methodology for scoping reviews [ 35 , 36 ]. Although ethics approval is not required for scoping reviews the broader study was approved by the University Ethics Committee (approval number HEC 21249).

Search strategy

A pilot search strategy was developed in consultation with an expert health librarian and tested in MEDLINE (OVID) and conducted on 3 June 2022. Articles from this pilot search were compared with seminal articles previously identified by the members of the team and used to refine the search terms. The search terms were then searched as both keywords and subject headings (e.g., MeSH) in the titles and abstracts and Boolean operators employed. A full MEDLINE search was then carried out by the librarian (see Table  1 ). This search strategy was adapted for use in each of the following databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE), Web of Science and PsychInfo databases. The references of included studies have been hand-searched to identify any additional evidence sources.

Study/source of evidence selection

Following the search, all identified citations were collated and uploaded into EndNote v.X20 (Clarivate Analytics, PA, USA) and duplicates removed. The resulting articles were then imported into Covidence – Cochrane’s systematic review management software [ 41 ]. Duplicates were removed once importation was complete, and title and abstract screening was undertaken against the eligibility criteria. A sample of 25 articles were assessed by all reviewers to ensure reliability in the application of the inclusion and exclusion criteria. Team discussion was used to ensure consistent application. The Covidence software supports blind reviewing with two reviewers required at each screening phase. Potentially relevant sources were retrieved in full text and were assessed against the inclusion criteria by two independent reviewers. Conflicts were flagged within the software which allows the team to discuss those that have disagreements until a consensus was reached. Reasons for exclusion of studies at full text were recorded and reported in the scoping review. The Preferred Reporting Items of Systematic Reviews extension for scoping reviews (PRISMA-ScR) checklist was used to guide the reporting of the review [ 42 ] and all stages were documented using the PRISMA-ScR flow chart [ 42 ].

Data extraction

A data extraction form was created in Covidence and used to extract study characteristics and to confirm the study’s relevance. This included specific details such as article author/s, title, year of publication, country, aim, population, setting, data collection methods and key findings relevant to the review question. The draft extraction form was modified as needed during the data extraction process.

Data analysis and presentation

Extracted data were summarised in tabular format (see Table  2 ). Consistent with the guidelines for the effective reporting of scoping reviews [ 43 ] and the JBI framework [ 35 ] the final stage of the review included thematic analysis of the key findings of the included studies. Study findings were imported into QSR NVivo with coding of each line of text. Descriptive codes reflected key aspects of the included studies related to the motivations and behaviours of women > 75 years about breast cancer screening.

In line with the reporting requirements for scoping reviews the search results for this review are presented in Fig.  1 [ 44 ].

A total of fourteen [ 14 ] studies were included in the review with studies from the following countries, US n  = 12 [ 33 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ], UK n  = 1 [ 23 ] and France n  = 1 [ 56 ]. Sample sizes varied, with most containing fewer than 50 women ( n  = 8) [ 33 , 45 , 46 , 48 , 51 , 52 , 55 ]. Two had larger samples including a French study with 136 women (a sub-set of a larger sample) [ 56 ], and one mixed method study in the UK with a sample of 26 women undertaking interviews and 479 women completing surveys [ 23 ]. One study did not report exact numbers [ 50 ]. Three studies [ 47 , 53 , 54 ] were undertaken by a group of researchers based in the US utilising the same sample of women, however each of the papers focused on different primary outcomes. The samples in the included studies were recruited from a range of locations including primary medical care clinics, specialist medical clinics, University affiliated medical clinics, community-based health centres and community outreach clinics [ 47 , 53 , 54 ].

Data collection methods varied and included: quantitative ( n  = 8), qualitative ( n  = 5) and mixed methods ( n  = 1). A range of data collection tools and research designs were utilised; pre/post, pilot and cross-sectional surveys, interviews, and secondary analysis of existing data sets. Seven studies focused on the use of a Decision Aids (DAs), either in original or modified form, developed by Schonberg et al. [ 55 ] as a tool to increase knowledge about the harms and benefits of screening for older women [ 45 , 47 , 48 , 49 , 52 , 54 , 55 ]. Three studies focused on intention to screen [ 33 , 53 , 56 ], two on knowledge of, and attitudes to, screening [ 23 , 46 ], one on information needs relating to risks and benefits of screening discontinuation [ 51 ], and one on perceptions about discontinuation of screening and impact of social interactions on screening [ 50 ].

The three themes developed from the analysis of the included studies highlighted that decisions about screening were primarily influenced by: (1) knowledge of the benefits and harms of screening and their relationship to age; (2) underlying attitudes to the importance of cancer screening in women's lives; and (3) exposure to decision aids designed to facilitate informed decision-making. Each of these themes will be presented below drawing on the key findings of the appropriate studies. The full dataset of extracted data can be found in Table  2 .

Knowledge of the benefits and harms of screening ≥ 75 years

The decision to participate in routine mammography is influenced by individual differences in cognition and affect, interpersonal relationships, provider characteristics, and healthcare system variables. Women typically perceive mammograms as a positive, beneficial and routine component of care [ 46 ] and an important aspect of taking care of themselves [ 23 , 46 , 49 ]. One qualitative study undertaken in the US showed that few women had discussed mammography cessation or the potential harms of screening with their health care providers and some women reported they would insist on receiving mammography even without a provider recommendation to continue screening [ 46 ].

Studies suggested that ageing itself, and even poor health, were not seen as reasonable reasons for screening cessation. For many women, guidance from a health care provider was deemed the most important influence on decision-making [ 46 ]. Preferences for communication about risk and benefits were varied with one study reporting women would like to learn more about harms and risks and recommended that this information be communicated via physicians or other healthcare providers, included in brochures/pamphlets, and presented outside of clinical settings (e.g., in community-based seniors groups) [ 51 ]. Others reported that women were sometimes sceptical of expert and government recommendations [ 33 ] although some were happy to participate in discussions with health educators or care providers about breast cancer screening harms and benefits and potential cessation [ 52 ].

Underlying attitudes to the importance of cancer screening at and beyond 75 years

Included studies varied in describing the importance of screening, with some attitudes based on past attendance and some based on future intentions to screen. Three studies reported findings indicating that some women intended to continue screening after 75 years of age [ 23 , 45 , 46 ], with one study in the UK reporting that women supported an extension of the automatic recall indefinitely, regardless of age or health status. In this study, failure to invite older women to screen was interpreted as age discrimination [ 23 ]. The desire to continue screening beyond 75 was also highlighted in a study from France that found that 60% of the women ( n  = 136 aged ≥ 75) intended to pursue screening in the future, and 27 women aged ≥ 75, who had never undergone mammography previously (36%), intended to do so in the future [ 56 ]. In this same study, intentions to screen varied significantly [ 56 ]. There were no sociodemographic differences observed between screened and unscreened women with regard to level of education, income, health risk behaviour (smoking, alcohol consumption), knowledge about the importance and the process of screening, or psychological features (fear of the test, fear of the results, fear of the disease, trust in screening impact) [ 56 ]. Further analysis showed that three items were statistically correlated with a higher rate of attendance at screening: (1) screening was initiated by a physician; (2) the women had a consultation with a gynaecologist during the past 12 months; and (3) the women had already undergone at least five screening mammograms. Analysis highlighted that although average income, level of education, psychological features or other types of health risk behaviours did not impact screening intention, having a mammogram previously impacted likelihood of ongoing screening. There was no information provided that explained why women who had not previously undergone screening might do so in the future.

A mixed methods study in the UK reported similar findings [ 23 ]. Utilising interviews ( n  = 26) and questionnaires ( n  = 479) with women ≥ 70 years (median age 75 years) the overwhelming result (90.1%) was that breast screening should be offered to all women indefinitely regardless of age, health status or fitness [ 23 ], and that many older women were keen to continue screening. Both the interview and survey data confirmed women were uncertain about eligibility for breast screening. The survey data showed that just over half the women (52.9%) were unaware that they could request mammography or knew how to access it. Key reasons for screening discontinuation were not being invited for screening (52.1%) and not knowing about self-referral (35.1%).

Women reported that not being invited to continue screening sent messages that screening was no longer important or required for this age group [ 23 ]. Almost two thirds of the women completing the survey (61.6%) said they would forget to attend screening without an invitation. Other reasons for screening discontinuation included transport difficulties (25%) and not wishing to burden family members (24.7%). By contrast, other studies have reported that women do not endorse discontinuation of screening mammography due to advancing age or poor health, but some may be receptive to reducing screening frequency on recommendation from their health care provider [ 46 , 51 ].

Use of Decision Aids (DAs) to improve knowledge and guide screening decision-making

Many women reported poor knowledge about the harms and benefits of screening with studies identifying an important role for DAs. These aids have been shown to be effective in improving knowledge of the harms and benefits of screening [ 45 , 54 , 55 ] including for women with low educational attainment; as compared to women with high educational attainment [ 47 ]. DAs can increase knowledge about screening [ 47 , 49 ] and may decrease the intention to continue screening after the recommended age [ 45 , 52 , 54 ]. They can be used by primary care providers to support a conversation about breast screening intention and reasons for discontinuing screening. In one pilot study undertaken in the US using a DA, 5 of the 8 women (62.5%) indicated they intended to continue to receive mammography; however, 3 participants planned to get them less often [ 45 ]. When asked whether they thought their physician would want them to get a mammogram, 80% said “yes” on pre-test; this figure decreased to 62.5% after exposure to the DA. This pilot study suggests that the use of a decision-aid may result in fewer women ≥ 75 years old continuing to screen for breast cancer [ 45 ].

Similar findings were evident in two studies drawing on the same data undertaken in the US [ 48 , 53 ]. Using a larger sample ( n  = 283), women’s intentions to screen prior to a visit with their primary care provider and then again after exposure to the DA were compared. Results showed that 21.7% of women reduced their intention to be screened, 7.9% increased their intentions to be screened, and 70.4% did not change. Compared to those who had no change or increased their screening intentions, women who had a decrease in screening intention were significantly less likely to receive screening after 18 months. Generally, studies have shown that women aged 75 and older find DAs acceptable and helpful [ 47 , 48 , 49 , 55 ] and using them had the potential to impact on a women’s intention to screen [ 55 ].

Cadet and colleagues [ 49 ] explored the impact of educational attainment on the use of DAs. Results highlight that education moderates the utility of these aids; women with lower educational attainment were less likely to understand all the DA’s content (46.3% vs 67.5%; P < 0.001); had less knowledge of the benefits and harms of mammography (adjusted mean ± standard error knowledge score, 7.1 ± 0.3 vs 8.1 ± 0.3; p < 0.001); and were less likely to have their screening intentions impacted (adjusted percentage, 11.4% vs 19.4%; p  = 0.01).

This scoping review summarises current knowledge regarding motivations and screening behaviours of women over 75 years. The findings suggest that awareness of the importance of breast cancer screening among women aged ≥ 75 years is high [ 23 , 46 , 49 ] and that many women wish to continue screening regardless of perceived health status or age. This highlights the importance of focusing on motivation and screening behaviours and the multiple factors that influence ongoing participation in breast screening programs.

The generally high regard attributed to screening among women aged ≥ 75 years presents a complex challenge for health professionals who are focused on potential harm (from available national and international guidelines) in ongoing screening for women beyond age 75 [ 18 , 20 , 57 ]. Included studies highlight that many women relied on the advice of health care providers regarding the benefits and harms when making the decision to continue breast screening [ 46 , 51 , 52 ], however there were some that did not [ 33 ]. Having a previous pattern of screening was noted as being more significant to ongoing intention than any other identified socio-demographic feature [ 56 ]. This is perhaps because women will not readily forgo health care practices that they have always considered important and that retain ongoing importance for the broader population.

For those women who had discontinued screening after the age of 74 it was apparent that the rationale for doing so was not often based on choice or receipt of information, but rather on factors that impact decision-making in relation to screening. These included no longer receiving an invitation to attend, transport difficulties and not wanting to be a burden on relatives or friends [ 23 , 46 , 51 ]. Ongoing receipt of invitations to screen was an important aspect of maintaining a capacity to choose [ 23 ]. This was particularly important for those women who had been regular screeners.

Women over 75 require more information to make decisions regarding screening [ 23 , 52 , 54 , 55 ], however health care providers must also be aware that the element of choice is important for older women. Having a capacity to choose avoids any notion of discrimination based on age, health status, gender or sociodemographic difference and acknowledges the importance of women retaining control over their health [ 23 ]. It was apparent that some women would choose to continue screening at a reduced frequency if this option was available and that women should have access to information facilitating self-referral [ 23 , 45 , 46 , 51 , 56 ].

Decision-making regarding ongoing breast cancer screening has been facilitated via the use of Decision Aids (DAs) within clinical settings [ 54 , 55 ]. While some studies suggest that women will make a decision regardless of health status, the use of DAs has impacted women’s decision to screen. While this may have limited benefit for those of lower educational attainment [ 48 ] they have been effective in improving knowledge relating to harms and benefits of screening particularly where they have been used to support a conversation with women about the value of screening [ 54 , 55 , 56 ].

Women have identified challenges in engaging in conversations with health care providers regarding ongoing screening, because providers frequently draw on projections of life expectancy and over-diagnosis [ 17 , 51 ]. As a result, these conversations about screening after age 75 years often do not occur [ 46 ]. It is likely that health providers may need more support and guidance in leading these conversations. This may be through the use of DAs or standardised checklists. It may be possible to incorporate these within existing health preventive measures for this age group. The potential for advice regarding ongoing breast cancer screening to be available outside of clinical settings may provide important pathways for conversations with women regarding health choices. Provision of information and advice in settings such as community based seniors groups [ 51 ] offers a potential platform to broaden conversations and align sources of information, not only with health professionals but amongst women themselves. This may help to address any misconception regarding eligibility and access to services [ 23 ]. It may also be aligned with other health promotion and lifestyle messages provided to this age group.

Limitations of the review

The searches that formed the basis of this review were carried in June 2022. Although the search was comprehensive, we have only captured those studies that were published in the included databases from 2009. There may have been other studies published outside of these periods. We also limited the search to studies published in English with full-text availability.

The emphasis of a scoping review is on comprehensive coverage and synthesis of the key findings, rather than on a particular standard of evidence and, consequently a quality assessment of the included studies was not undertaken. This has resulted in the inclusion of a wide range of study designs and data collection methods. It is important to note that three studies included in the review drew on the same sample of women (283 over > 75)[ 49 , 53 , 54 ]. The results of this review provide valuable insights into motivations and behaviours for breast cancer screening for older women, however they should be interpreted with caution given the specific methodological and geographical limitations.

Conclusion and recommendations

This scoping review highlighted a range of key motivations and behaviours in relation to breast cancer screening for women ≥ 75 years of age. The results provide some insight into how decisions about screening continuation after 74 are made and how informed decision-making can be supported. Specifically, this review supports the following suggestions for further research and policy direction:

Further research regarding breast cancer screening motivations and behaviours for women over 75 would provide valuable insight for health providers delivering services to women in this age group.

Health providers may benefit from the broader use of decision aids or structured checklists to guide conversations with women over 75 regarding ongoing health promotion/preventive measures.

Providing health-based information in non-clinical settings frequented by women in this age group may provide a broader reach of information and facilitate choices. This may help to reduce any perception of discrimination based on age, health status or socio-demographic factors.

Availability of data and materials

Cancer Australia, in their 2014 position statement, define “overdiagnosis” in the following way. ‘’Overdiagnosis’ from breast screening does not refer to error or misdiagnosis, but rather refers to breast cancer diagnosed by screening that would not otherwise have been diagnosed during a woman’s lifetime. “Overdiagnosis” includes all instances where cancers detected through screening (ductal carcinoma in situ or invasive breast cancer) might never have progressed to become symptomatic during a woman’s life, i.e., cancer that would not have been detected in the absence of screening. It is not possible to precisely predict at diagnosis, to which cancers overdiagnosis would apply.” (accessed 22. nd August 2022; https://www.canceraustralia.gov.au/resources/position-statements/overdiagnosis-mammographic-screening ).
