120 Psychology Dissertation Topics for UK Students 2026

How to Choose a Psychology Dissertation Topic

Choosing a psychology dissertation topic requires you to balance several considerations: the topic must be genuinely original, ethically feasible, supported by sufficient peer-reviewed literature, researchable within your word limit and resource constraints, and aligned with your supervisor’s expertise. Psychology is a broad discipline, encompassing clinical, cognitive, developmental, social, forensic, health, occupational, and neuropsychological specialisms, and the best dissertation topics tend to sit at the intersection of a specific subdiscipline and a contemporary real-world question.

Use the 120 topics below — organised by subdiscipline — as a stimulus for discussion with your supervisor. Remember that a topic title is a starting point: your research question should be sharper and more specific than a broad title, and your methodology must be appropriate to the question.

Frequently Asked Questions

What is the typical structure of a psychology dissertation at UK universities?
Most UK psychology dissertations follow the IMRaD structure: Introduction (literature review and rationale), Method (participants, design, materials, procedure), Results (statistical or qualitative analysis), and Discussion (interpretation, limitations, implications). Some programmes require an additional abstract and standardised appendices (ethics forms, materials, participant information sheets). Your programme handbook will specify the exact requirements.

Do I need ethical approval for my psychology dissertation?
Yes — almost all psychology dissertations that involve collecting data from human participants require ethics approval from your university’s ethics committee. The application process requires you to describe your study, data protection measures, informed consent procedures, and potential risks. Begin the ethics process early, as approval can take several weeks.

Can I conduct a systematic review for my psychology dissertation instead of empirical research?
Yes — systematic reviews, meta-analyses, and narrative literature reviews are well-regarded in psychology, particularly at postgraduate level. They require a transparent, pre-registered search strategy and rigorous appraisal of included studies. Many undergraduate programmes also accept literature review dissertations. Confirm the accepted methodology types with your programme director.

What statistical analysis should I use for my psychology dissertation?
The appropriate analysis depends on your research design and the type of data you collect. Common approaches include t-tests and ANOVA (comparing group means), correlation and regression (testing relationships between variables), and thematic analysis or interpretative phenomenological analysis (IPA) for qualitative data. Many UK psychology programmes use SPSS for quantitative analysis. Consult your research methods tutor early about which analysis best suits your design.
