Risk-Taking Behaviour and Criminal Responsibility: A Preliminary Investigation with Offenders and Forensic Psychiatric Patients

Roxana E. Moghaddam, Monica F. Tomlinson

The present study investigated whether individuals found criminally responsible (CR) differ from individuals found Not Criminally Responsible on Account of Mental Disorder (NCRMD) on behavioural measures of risktaking. Risk-taking was measured using two computerized tasks, the Balloon Analogue Risk Task (BART) and the Iowa Gambling Task (IGT). CR individuals were hypothesized to show greater risk-taking behaviours compared to NCRMD individuals. Performance on the IGT and BART was also hypothesized to predict NCRMD or CR group membership. Thirty-eight forensic psychiatric patients and offenders participated in this study. A t-test and logistic regression were conducted to address these hypotheses. No significant differences in risk-taking were found between NCRMD and CR individuals on the IGT and BART. Further, performance on the IGT and BART did not predict NCRMD or CR group membership. These results suggest that NCRMD and CR individuals are similar in levels of risk and may be similar in other criminogenic needs that have not been studied here. Future research is needed to understand the extent to which the rehabilitative needs of forensic psychiatric patients and offenders overlap.
