How to Write a Literature Review

As a student, writing a robust and well-researched literature review is a crucial part of your academic journey. The literature review serves as the foundation for your entire research project, allowing you to demonstrate your in-depth understanding of the existing knowledge in your field of study.

What is the purpose of a literature review?

The primary purpose of a literature review is to provide a comprehensive overview of the current research, theories, and debates surrounding your topic. By critically analyzing and synthesizing the relevant scholarly sources, you can:

• Identify gaps in the existing knowledge: Pinpoint areas that require further investigation or where your research can contribute.

• Establish the relevance and significance of your study: Demonstrate how your research aligns with and builds upon the field’s current state.

• Develop a strong theoretical and conceptual framework: Use the literature to inform your study’s theoretical underpinnings and methodological approach.

• Refine your research questions and objectives: Ensure your research addresses important questions in the field.

Here are the steps for writing a well-researched literature review:

Step 1 – Search for relevant literature

Before you begin your literature review, it’s essential to have a clear and well-defined research question or topic. This will help you focus your search and ensure that you are collecting the most relevant and valuable sources.

Developing a literature review research question

What is the impact of social media on body image perceptions and self-esteem among adolescents and young adults in Generation Z?

Identify relevant keywords

Start by creating a list of keywords related to your research question. Include the key concepts, variables, and population of interest. Consider synonyms and related terms to broaden your search.

Example keywords

• Social media (e.g., Facebook, Instagram, TikTok, Snapchat)
• Body image
• Self-perception
• Self-esteem
• Generation Z
• Adolescents
• Young adults

Search for relevant source

With your research question and keywords, begin searching for relevant scholarly sources. Utilize a variety of academic databases and search engines, such as:

• Your university’s library catalog
• Google Scholar
• EBSCO
• PsycINFO
• Web of Science
• Scopus

When searching, try using Boolean operators (e.g., AND, OR, NOT) to refine your results. Additionally, look for related articles and check the reference lists of any particularly useful sources.

Remember to read the abstracts carefully to determine the relevance and quality of each source before including it in your review. This will help you identify your topic’s most valuable and up-to-date literature.

Step 2 – Evaluate and select sources

Now that you have compiled an initial list of potentially relevant sources, it’s time to carefully evaluate each to determine which will be most valuable for your literature review.

When examining the sources, ask yourself the following questions:

• What is the main question or problem the author is addressing?
• What are the key concepts, and how are they defined?
• What theoretical frameworks, models, or methodologies are used?
• Are the research methods appropriate and well-executed?
• What are the key findings and conclusions of the study?
• How does this source relate to and build upon the existing knowledge on the topic?
• What are the strengths and limitations of the research?
• Is the source published in a reputable, peer-reviewed journal or by a credible publisher?

Pay close attention to the credibility and authority of the authors, as well as the timeliness and relevance of the information. Landmark studies, seminal theories, and recent high-quality research should be prioritized.

Look for potential biases or conflicts of interest that could compromise the source’s objectivity. Cross-checking information across multiple credible sources can also help you evaluate the reliability of the research.

Step 3 – Identify themes, debates, and gaps

As you closely review the sources you have gathered, look for emerging themes, key debates, and potential gaps in the existing research. This step is crucial for helping you organize your literature review and identify areas where your own research can contribute meaningful insights.

Identify Themes

Examine the sources to identify recurring concepts, theories, or approaches that suggest important themes within the literature. These themes could be related to:

• Key variables or factors (e.g., social media use, body image, self-esteem)
• Methodological approaches (e.g., qualitative, quantitative, mixed-methods) 
• Theoretical frameworks (e.g., social comparison theory, objectification theory)
• Populations or contexts studied (e.g., adolescents, young adults, specific cultures)

Detect Debates and Contradictions

Look for points of disagreement, contradictory findings, or conflicting interpretations across the sources. These debates may center around:

• The magnitude or direction of relationships between key variables
• The underlying mechanisms or explanatory models
• The relative importance or influence of different factors
• The generalizability of findings to diverse populations or settings

Uncover Gaps in the Literature

As you synthesize the literature, identify areas with limited attention or where the existing research is sparse or inconclusive. These gaps could be related to:

• Specific populations, contexts, or phenomena that have been understudied
• Methodological limitations or inconsistencies across studies
• Conflicting theoretical perspectives that require further exploration
• Practical applications or real-world implications that have not been addressed

Examples of Themes, Debates, and Gaps

In reviewing the literature on social media and body image, you may observe the following:

Themes

The predominance of research focusing on young women and their experiences

The increasing emphasis on the visual aspects of social media platforms like Instagram

Debates 

Conflicting findings on the direction and magnitude of the relationship between social media use and body image concerns

Disagreements about the underlying mechanisms linking social media and body image (e.g., social comparison, idealization, peer influence)

Gaps

Limited research on the impacts of highly visual social media platforms (e.g., Instagram, Snapchat) on body image, especially among diverse populations beyond young women

Lack of longitudinal studies examining the long-term effects of social media use on body image perceptions and self-esteem

Identifying these key themes, debates, and gaps will help you develop a cohesive structure and narrative for your literature review while highlighting opportunities for your research to make a meaningful contribution to the field.

Step 4 – Outline your literature review’s structure

When structuring your literature review, you have several organizational approaches, depending on their length, scope, and focus. You can employ a single approach or combine multiple strategies to create a coherent and compelling structure.

Chronological Organization

A chronological approach traces the development of the topic over time. This allows you to highlight key turning points, emerging trends, and the evolution of theoretical and methodological approaches. However, avoid simply listing and summarizing sources in a purely chronological order. Instead, analyze patterns, debates, and critical events that have shaped the direction of the field.

Thematic Organization

Organizing your literature review around central themes is an effective way to synthesize the existing research. Identify recurring topics, concepts, or perspectives from your sources and use these as the basis for your main sections or subsections. This thematic structure helps you critically analyze how different studies relate to and build upon one another.

Methodological Organization

If your sources employ diverse research methods, you can structure your review to compare and contrast the approaches, findings, and conclusions from different methodological frameworks. This could involve grouping studies using qualitative, quantitative, mixed methods or disciplinary perspectives (e.g., sociological, historical, cultural).

Theoretical Organization

Your literature review can also be structured around the theoretical foundations and conceptual frameworks that underpin the existing research. Discuss how key theories, models, and definitions have been applied and debated within the literature. This approach can help you establish a strong theoretical basis for your own study.

Step 5 – Write your literature review

When writing your literature review, approach it with the same care and structure as any other academic paper. Your review should have a clear introduction, a well-organized body, and a concise conclusion.

Introduction

The introduction to your literature review should establish your analysis’s focus, scope, and purpose. Restate your research question or the central problem you are exploring, and provide a brief overview of the scholarly context. You can also highlight the timeliness or significance of your topic and identify any key gaps in the existing literature that your review will address.

Body

Your literature review should be organized around the major themes, debates, and methodological approaches that emerged from your analysis of the sources. Depending on the length and complexity of your review, you may want to divide the body into clearly delineated sections or subsections.

As you write the body, aim to:

• Summarize and synthesize the key findings, theories, and conclusions across the sources
• Analyze and interpret the significance and implications of the research
• Critically evaluate the strengths, weaknesses, and limitations of the existing studies
• Draw connections, comparisons, and contrasts between the sources to develop a coherent narrative
• Use well-structured paragraphs with effective transitions to guide the reader

Conclusion

In the concluding section of your literature review, summarize the key takeaways and reiterate the overall significance of the research you have examined. Emphasize how your review has addressed important gaps or limitations in the existing literature, and explain how it lays the foundation for your own study or contributes to advancing knowledge in the field.
