The present study investigated 154 consecutive admissions to the Regional Treatment Center (Ontario) Sex Offender Treatment Program with reference to psychopathy and outcome. Ratings of treatment behavior, as well as clinical judgments as to whether risk was reduced, were coded based on treatment reports. With reference to Psychopathy Checklist-revised (PCL-R) scores, survival analyses indicated that high scorers recidivated at significantly higher rates than low scorers. However, offenders who received high PCL-R scores and lower scores on measures of treatment behavior recidivated at the same rate as low scorers on the PCL-R. Furthermore, among high PCL-R offenders, those rated as lower risk at post treatment in fact reoffended at a lower rate than those whose risk was rated as unchanged, although this difference failed to reach significance. Findings are discussed in light of the clinical and research literature.

Follow-up data are reported on 89 sexual offenders treated at the Regional Treatment Centre (Ontario) and 89 untreated sexual offenders matched for pretreatment risk. The average time at risk was 9.9 years. It was found that the treated group had a sexual recidivism rate of 23.6%, whereas the untreated group had a sexual recidivism rate of 51.7% (p <.0001). The groups also differed significantly on nonsexual recidivism. Data on a new analytic technique, the Criminal Career Profile, are also reported. Results are discussed with reference to the recent outcome study of Quinsey, Khanna, and Malcolm.

The current paper critically reviews the Risk-Need-Responsivity (RNR) and Good Lives Model (GLM) approaches to correctional treatment. Research, or the lack thereof, is discussed in terms of whether there is a need for a new model of offender rehabilitation. We argue that although there is a wealth of research in support of RNR approaches, there is presently very little available research demonstrating the efficacy of the GLM in terms of the impact that programs based on this model of rehabilitation have on observed rates of recidivism among offender populations. Additionally, the emphasis of the GLM approach on the principles and techniques of positive psychology is untested in the area of forensic psychology. Evidence with reference to the assessment and treatment of sexual offenders is discussed as this is a particular focus of the GLM approach. We conclude, in agreement with the developers of the GLM approach, that the RNR model needs to be adapted in order to incorporate recent research related to the factors associated with recidivism among sexual offenders. However, we argue that the GLM is largely an empirically untested model, and further offers little in terms of adding to or replacing the RNR model. We recognize that a revised version of the RNR based approach is necessary, incorporating an integrated approach to treatment, and we introduce and briefly describe the RNR-I (Integrated)), a model developed by the authors and supported by a variety of empirical research, including a number of outcome studies produced by our team and others.

Andrews and Bonta (2003) have presented a model of effective correctional programming focusing on risk, need, and responsivity factors for a general criminal population. When applied to sexual offenders, the first two issues (risk assessment and treatment targets such as cognitive distortions) have received a great deal of research attention. However, little attention has been paid to responsivity issues: those factors that influence the extent to which clients benefit, or fail to benefit, from treatment programs. This article presents a review of several potential responsivity factors related to sexual offender treatment and outlines areas that require further research attention.

According to a literature review by Marshall (1996), presently available data have not clarified the proportion of sexual offenders who would meet diagnostic criteria for addictive problems. Our own literature review failed to find published studies comparing sexual offenders to nonsexual violent offenders on standardized measures of substance abuse. Our study is a preliminary investigation of the differences between sexual offenders (rapists: n = 72; child molesters: n = 34) and nonsexual violent offenders (n = 24) on measures of alcohol and drug abuse. The findings indicate that sexual offenders were more likely to abuse alcohol than were nonsexual violent offenders. Nonsexual offenders were significantly more likely to have had a history of other forms of substance abuse. The results are considered in terms of theories of alcohol's contribution to aggressive behavior and sexual aggression. Implications for assessment and treatment of sexual offenders are discussed.
