Abstract

Two studies related to substance abuse and sexual offending were conducted. In the first study, a sample of 94 sexual offenders and 21 violent non-sexual offenders, incarcerated within the Ontario Region of Correctional Service of Canada (CSC), were administered the Michigan Alcohol Screening Test (MAST), the Drug Abuse Screening Test (DAST) and the Relationship Styles Questionnaire (RSQ). The Hare Psychopathy Checklist–Revised (PCL-R) was also scored for the majority of offenders included in the present study. Results indicated that the groups differed on PCL-R score, with both rapists and violent non-sexual offenders scoring significantly higher than the child molesters with reference to total PCL-R score. Sex offenders’ mean score on the MAST were significantly higher than those of the violent non-sexual offenders. The mean score on the MAST for sex offenders was in the problem drinking range. With reference to attachment pattern, sex offenders were found to be more preoccupied than violent non-sexual comparison subjects. In the second study, a sample of sexual offenders, all of whom exhibited elevated levels of alcohol abuse as measured by the MAST, were divided into two groups based on whether or not they had completed a substance abuse treatment programme. Sexual offenders (all of whom received sex offender-specific treatment) who also received substance abuse treatment evidenced significantly lower levels of general recidivism than those who did not complete such treatment. Results are discussed in light of previous findings in relation to differing patterns of substance abuse between sexual and violent non-sexual offenders observed in the literature as well as with reference to Marshall's attachment theory.
