Psychology Dissertation Topics: 20 Ideas for Top Grades

Choosing strong psychology dissertation topics is the foundation on which every other aspect of your dissertation project rests. A well-chosen psychology dissertation topic gives you a focused research question, an accessible body of relevant literature, a feasible methodology, and a clear sense of what your research will contribute to the field. A poorly chosen one undermines every subsequent effort.

This guide presents 20 strong psychology dissertation topic ideas across the major subdisciplines of psychology, with explanations of the research angle that makes each viable as a final-year or postgraduate dissertation.

What Makes Strong Psychology Dissertation Topics

The strongest psychology dissertation topics share several characteristics. They are specific — focused on a defined phenomenon, population, or context rather than an entire area of psychology. They are grounded in the existing literature — identifiable in the published research and clearly responding to a gap or debate in that literature. They are methodologically feasible — addressable with the research methods and resources available to you. And they are clinically, theoretically, or socially significant — their findings would matter to someone beyond the dissertation itself.

Avoid psychology dissertation topics that are so broad they cannot be addressed in depth, so niche they have no connection to existing literature, or so dependent on difficult-to-access populations or data that they cannot be practically conducted within a standard dissertation timeline.

Clinical and Counselling Psychology Dissertation Topics

Topic 1: Cognitive Behavioral Therapy Effectiveness for Anxiety in Young Adults

A psychology dissertation topic here could examine CBT effectiveness in a specific anxiety disorder, in a specific demographic group, or in a specific delivery format such as online CBT.

Topic 2: Perfectionism and Academic Burnout in University Students

The relationship between perfectionism, academic pressure, and burnout is a well-studied area with ongoing debates about the mechanisms involved.

Topic 3: Attachment Style and Romantic Relationship Satisfaction

Attachment theory provides a well-developed framework for understanding relationship functioning. A psychology dissertation topic in this area could examine how attachment styles predict specific dimensions of relationship satisfaction, how they interact with partner attachment style, or how attachment security changes over the course of a relationship.

Topic 4: The Effectiveness of Mindfulness-Based Interventions for Depression

Mindfulness-based cognitive therapy is an evidence-based treatment for recurrent depression.

Social and Health Psychology Dissertation Topics

Topic 6: Social Media Use and Body Image in Adolescent Girls

Topic 10: Health Behaviour Change and Self-Determination Theory

Self-determination theory is one of the most robust frameworks for understanding motivation in health behaviour change.

Cognitive and Neuropsychology Dissertation Topics

Topic 11: Working Memory Capacity and Academic Achievement
