Forensic Psychology Dissertation Topics With Research Aims
Topic 1: The Role of Moral Injury in the Development of Violent Behaviour Among Military Veterans Involved in the Criminal Justice System
Research Aim:This study aims to understand how deep emotional wounds from military service, known as moral injuries, might influence some veterans to act violently after returning to civilian life, especially those who end up in trouble with the law.
Topic 2: A Longitudinal Analysis of the Psychological Effects of AI-Based Surveillance on Offender Rehabilitation and Recidivism
Research Aim: This research looks at how being constantly watched by AI surveillance systems over time affects the mindset, behaviour, and progress of people trying to change their lives after committing crimes, and whether it helps or harms their chances of staying out of trouble.
Topic 3: The Impact of Deepfake Evidence on Juror Trust, Perception of Guilt, and Legal Decision-Making in Criminal Trials
Research Aim: This study explores how fake video or audio evidence, created using advanced technology (deepfakes), might confuse jurors in court, affecting how much they trust the evidence and how fairly they judge whether someone is guilty or innocent.
Topic 4: Rapport-Based Interviewing and Information Disclosure in Suspect Interviews: A Mock Interview Experiment with Student Participants
Research Aim: This study will test whether a rapport-based interviewing style produces more checkable detail than a confrontational style.
Student participants will complete a staged mock theft task and then be interviewed under one of the two styles. Transcripts will be coded for the amount and accuracy of information disclosed.
Topic 5: Mock Juror Perceptions of Autistic Defendants: Effects of Diagnostic Disclosure on Credibility Ratings and Verdict Preferences
Research Aim: This experiment will examine whether telling mock jurors that a defendant is autistic changes how they interpret courtroom demeanour.
Adult participants will read a trial summary with or without a diagnostic label and a judicial explanation. They will then rate credibility and blame, choose a verdict and explain their reasoning.
Topic 6: Victim Blame and Reporting Intentions in Online Sexual Extortion: A Vignette Experiment with University Students
Research Aim: This study will examine how young adults judge victims of financially motivated sexual extortion and whether they would report it.
University students will read vignettes that vary the victim’s gender and the platform used. They will rate blame, seriousness and their likelihood of telling the police, family or the platform.
Topic 7: Trust in Algorithmic Reoffending Scores: Automation Bias in Risk Judgements by Postgraduate Students Using Probation Case Vignettes
Research Aim: This research will test whether an actuarial reoffending score pulls risk judgements away from the case evidence.
Postgraduate forensic psychology and criminology students will rate fictional probation cases presented with a high score, a low score or no score. Ratings and written rationales will show how strongly the score anchors decisions.
Topic 8: Child First Diversion for Children at Risk of Criminal Exploitation: Practitioner Perspectives in Youth Justice Services
Research Aim: This study will explore how youth justice practitioners in England and Wales apply Child First approaches when diverting children who may be criminally exploited.
Semi-structured interviews will examine how staff balance safeguarding, risk management and the child’s own voice, and what helps or hinders diversion in practice.

Frequently Asked Questions
Start with the stage of the justice process that interests you most: investigation, trial, custody, community supervision or victim support. Then read current issues of journals such as Legal and Criminological Psychology or Psychology, Crime and Law to see which questions are still open.
Narrow the idea to one population, one setting and one measurable outcome, and check early that you can reach the participants or records you need.
The most studied themes are investigative interviewing, eyewitness identification, jury decision-making, violence and reoffending risk assessment, rehabilitation in prison and probation, youth justice, online offending, and the experiences of victims and witnesses.
Growing areas include neurodivergent people in the justice system, professional trust in algorithmic risk tools, technology-facilitated abuse, and how jurors respond to digital and forensic evidence.
Yes. Most undergraduate and master’s projects use samples that are easier to reach. Mock juror and mock witness experiments, vignette studies, attitude surveys and interviews with practitioners in charities or local authority services all count as forensic psychology research.
Published material is another option. Inspection reports, inquiry evidence, court judgments and official statistics can be analysed without approval from a prison or police force.
Plan for distress, disclosure and confidentiality. Topics involving violence, abuse or victimisation need content warnings, a clear right to withdraw and details of support services. Decide in advance how you will respond if a participant discloses an unreported offence or a risk of harm.
Follow the British Psychological Society Code of Human Research Ethics and your university process. Research involving prison or probation staff, or the people they supervise, needs separate approval from the service, which in England and Wales does not accept undergraduate applications. Police forces set their own rules.
Name the population, the setting, the factor you will compare and the outcome you will measure. Eyewitness memory is a topic. Whether a self-administered interview improves recall accuracy after a one-week delay in adult mock witnesses is a research question.
Then check that the outcome can be measured with a validated scale, a coding scheme or an accuracy score, and that the design fits your timescale.
Yes. Complete the free topic form at the end of this page, or on our free dissertation topics page, and a subject specialist will send you a custom topic with an aim and justification.
