Recidivism Among Treated Sexual Offenders and a Matched Comparison of Untreated Sexual Offenders

The present investigation examined a sample of 64 offenders treated at the Regional Treatment Centre (Ontario) Sex Offender Treatment Program (RTCSOTP) and a sample of 55 untreated sexual offenders from the Ontario region of Correctional Service of Canada. Groups were matched on age at index offence, Hare Psychopathy Checklist-Revised (PCL-R) score and type of sexual offender. The Rapid Risk Assessment of Sexual Offence Recidivism Scale was scored on all participants. Recidivism, based upon officially recorded charges and conviction data, was the primary dependent measure. Results indicated that both treated participants and control participants, including those with high PCL-R scores, evidenced low sexual recidivism rates. Based on a survival analysis using time to recidivism as the dependent variable, no differences were found between treated and untreated sexual offenders. The need to consider a wider range of treatment outcome measures and the benefits of using dynamic methods of risk assessment are highlighted.MAS
