Presented in this session will be the results of a study of the problem gambling and other mental health problems in a sample of incarcerated Canadian male federal offenders. Results indicated that anxiety, depression, substance abuse, impulsivity, attention-deficit hyperactivity symptoms, and stressful life experiences are significantly correlated with problematic gambling. However, the effect sizes of some of these correlations for the offender sample are in general much smaller than have been found in general population samples. Differences between the offender sample and the non-offender samples will also be examined. In addition, we will examine the relationship between the type of crime (e.g., violent vs. income producing crimes) committed and the mental health variables.
