How to Write a Psychology Literature Review

A psychology literature review is a critical analysis of existing psychological research related to a specific topic or research question. It is one of the most important sections of a psychology dissertation because it demonstrates your understanding of psychological theories, research findings, methodologies, and gaps in the literature.

Unlike a simple summary of studies, a strong psychology literature review evaluates and synthesizes research to explain how previous findings connect to your own study.

What Is a Psychology Literature Review?

A psychology literature review examines published psychological research relevant to your dissertation topic.

Sources commonly include:

• Peer-reviewed psychology journal articles

• Academic books

• Meta-analyses and systematic reviews

• Psychological theories and frameworks

• Previous dissertations and studies

  
  

The purpose of the review is to:

• Summarize existing psychological research

• Analyze trends and findings

• Compare methodologies

• Identify gaps in the literature

• Support your research question or hypothesis

Why Is a Psychology Literature Review Important?

A strong literature review helps:

• Demonstrate knowledge of psychological theory

• Show understanding of previous research

• Justify the need for your study

• Identify limitations in existing research

• Build the theoretical foundation for your dissertation

In psychology, literature reviews are especially important because research findings are often connected to established theories and empirical evidence.

Step 1: Define Your Psychology Research Topic

Before beginning your literature review, clearly define your research topic or question.

Example:

• Broad topic: Anxiety in students

• Narrowed topic: The relationship between social media use and anxiety levels in university students

A focused topic makes it easier to locate relevant psychological research.

Step 2: Search for Psychology Sources

Psychology research relies heavily on peer-reviewed journal articles.

Common databases for psychology literature include:

• PsycINFO

• PubMed

• Google Scholar

• JSTOR

• Scopus

Focus on:

• Recent studies

• Foundational psychological theories

• Landmark empirical research

• Peer-reviewed academic sources

Try to prioritize scholarly journal articles over general websites.

Step 3: Read Critically and Take Notes

As you read studies, analyze:

• The purpose of the study

• Psychological theories used

• Methodology and participant sample

• Findings and conclusions

• Strengths and limitations

Good note-taking helps organize your literature later.

You may want to track:

• Author and publication year

• Research method (qualitative or quantitative)

• Psychological variables studied

• Key findings

• Relevance to your research question

Step 4: Identify Themes in the Literature

A psychology literature review should be organized by themes rather than individual studies.

Example themes for a psychology dissertation on anxiety:

• Social media use and mental health

• Academic stress in university students

• Self-esteem and psychological wellbeing

• Coping strategies and resilience

Grouping studies into themes improves clarity and analytical depth.

Step 5: Discuss Psychological Theories

Psychology literature reviews often include theoretical frameworks.

Examples include:

• Cognitive Behavioral Theory (CBT)

• Attachment Theory

• Social Learning Theory

• Self-Determination Theory

• Cognitive Load Theory

Discussing theory helps explain:

• Why certain behaviors occur

• How previous researchers interpreted findings

• How your study fits into existing psychology research

Step 6: Analyze and Compare Studies

A strong psychology literature review does more than summarize findings. It critically evaluates research.

You should:

• Compare results between studies

• Discuss contradictions or inconsistencies

• Evaluate methodologies

• Identify strengths and weaknesses

Weak example:

“Smith (2022) found that social media increases anxiety.”

Stronger example:

“While Smith (2022) found a positive relationship between social media use and anxiety, Brown (2023) suggested that the impact depended on the type of online interaction, highlighting the importance of contextual psychological factors.”

Critical analysis demonstrates advanced academic thinking.

Step 7: Identify Gaps in Psychology Research

One purpose of the literature review is to show where research is incomplete.

Research gaps may include:

• Understudied populations

• Inconsistent findings

• Limited qualitative research

• Lack of longitudinal studies

• Emerging topics such as AI and mental health

Your dissertation should help address one of these gaps.

Step 8: Use APA Referencing Correctly

Most psychology programs require APA formatting.

APA style includes:

• In-text citations

• Reference lists

• Specific heading structures

• Proper formatting for tables and figures

Accurate referencing is essential to avoid plagiarism and maintain academic integrity.

Common Mistakes in Psychology Literature Reviews

Students often struggle by:

• Summarizing studies without analysis

• Using outdated or non-scholarly sources

• Ignoring psychological theory

• Organizing by author instead of themes

• Including unrelated research

• Failing to connect literature to the research question

Avoiding these mistakes improves the overall quality of your dissertation.

Tips for Writing a Strong Psychology Literature Review

• Use mostly peer-reviewed journal articles

• Focus on recent psychology research when possible

• Organize studies into themes or concepts

• Link findings to psychological theories

• Critically analyze methodologies and findings

• Keep your research question central throughout the review

Final Thoughts

Writing a psychology literature review requires more than summarizing research—it involves analyzing psychological theories, evaluating empirical evidence, and identifying gaps in current knowledge. A strong literature review demonstrates scholarly understanding and provides the foundation for your dissertation study.

By organizing research carefully and critically evaluating existing literature, you can create a psychology literature review that strengthens your dissertation and supports meaningful psychological research.
