This study constitutes an extension of a study of sex offender outcomes prepared for the Evaluation Branch, Correctional Service of Canada. The entire cohort of 2,401 male federally incarcerated sexual offenders who reached their warrant expiry date (WED) within 1997/1998, 1998/1999, and 1999/2000 fiscal years were reviewed for the study. Sexual and violent reconviction information was obtained from CPIC criminal records over an average of 12.0 years (SD = 1.7) follow-up. This study focused upon the cohort of sex offenders who were 50 years or older at time of release (N = 542). They were stratified according to risk using a brief actuarial scale (BARS) comprising six binary variables. For the most part, older offenders showed low base rates of sexual recidivism regardless of the risk band into which they fell. The exception was a small group of elderly offenders (n = 20) who fell into the highest risk band, and who showed high levels of sexual recidivism. The results of this combination of cross-sectional and longitudinal analyses of elderly sexual offenders may have important implications for offender management, particularly in light of the increasing numbers of offenders in Canada who fall into the over 50 age cohort.

The VRS-SO was rated prospectively pre- and posttreatment by service providers, and several of the men had completed a psychometric battery at each time point. Prospective Stable 2000 ratings were examined for comparison purposes. Results of exploratory longitudinal factor analysis, performed on VRS-SO pre- and posttreatment dynamic item scores, supported a three-factor model (comparative fit index = .990) and the measurement invariance of the loadings over time. A stringent longitudinal confirmatory factor analysis of the VRS-SO items also supported the three-factor structure. Scores from the three factors (Sexual Deviance, Criminality, and Treatment Responsivity) were correlated in conceptually meaningful ways with scores from the Stable 2000 and selected psychometric measures. The results provide evidence for the construct validity of VRS-SO test scores as providing an index of sex offender risk and, more specifically, that its item content and factor domains measure psychological constructs pertinent to sex offender risk and need.

The study featured a combined international sample of 539 sex offenders followed up an average of 15.5 years post-release. Pre- and posttreatment VRS-SO ratings were amalgamated from two treated samples of sex offenders from Canada and New Zealand. Analyses focused on examinations and applications of change data and its relationship to sexual and violent recidivism. VRS-SO change scores were significantly associated with decreases in these outcome criteria with, and without, controlling for indicators of pretreatment risk (e.g., Static-99R score) and individual differences in follow-up time. Applications of logistic regression using fixed 5-year follow-ups generated estimated rates of sexual and violent recidivism at different VRS-SO score thresholds. The use of logistic regression demonstrated a clinically useful and systematic means of combining risk and change information into posttreatment risk appraisals. Implications for the use of change information in the assessment and management of sexual offender risk are discussed.

A multisite examination of sexual violence risk and therapeutic change / Mark E. OLVER ; Terry P. NICHOLAICHUK ; Drew A. KINGSTON ; Stephen C. P. WONG in Journal of Consulting and Clinical Psychology, Vol.82 - N°2 (April 2014)

Method: The present study featured the clinical application of a risk assessment and treatment planning tool, the Violence Risk Scale–Sexual Offender version (VRS-SO; Wong, Olver, Nicholaichuk, & Gordon, 2003). The VRS-SO was rated pre- and posttreatment by sex offender treatment providers on the sample of men who were attending institutionally based sex offender programs across the 5 regions of the Correctional Service of Canada. The Static-99 (Hanson & Thornton, 1999) was also rated as part of routine services, and the Static-99R was used for substantive analyses. Results: The VRS-SO dynamic factors and the Static-99R demonstrated significant predictive accuracy for sexual, violent, and general recidivism (area under the curve = .65 to .78). Significant pre-post changes on the VRS-SO dynamic factors were observed, ranging from small to moderate in magnitude (d = 0.22 to 0.62) across low, moderate, and high intensity programs. The change scores, in turn, were associated with decreases in the 3 recidivism outcomes; the majority of relationships examined attained significance after partialing out of pretreatment scores. Cox regression survival analyses, controlling for pretreatment risk, further demonstrated change scores to have associations with postrelease recidivism outcomes to varying degrees. Conclusions: The results are consistent with the dynamic nature of sexual violence risk and suggest that risk-relevant changes associated with participation in sexual offender treatment are linked to reductions in sexual offender recidivism.

All men participated in sexual offender treatment programming through the Correctional Service of Canada (CSC) at sites across its five regions. The Static-99R was also examined for comparison purposes. In total, 393 of the men were identified as Aboriginal (i.e., First Nations, Métis, Circumpolar) while 670 were non-Aboriginal and primarily White. Aboriginal men scored significantly higher on the Static-99R and VRS-SO and had higher rates of sexual and violent recidivism; however, there were no significant differences between Aboriginal and non-Aboriginal groups on treatment change with both groups demonstrating close to a half-standard deviation of change pre and post treatment. VRS-SO risk and change scores significantly predicted sexual and violent recidivism over fixed 5- and 10-year follow-ups for both racial/ancestral groups. Cox regression survival analyses also demonstrated positive treatment changes to be significantly associated with reductions in sexual and violent recidivism among Aboriginal and non-Aboriginal men after controlling baseline risk. A series of follow-up Cox regression analyses demonstrated that risk and change score information accounted for much of the observed differences between Aboriginal and non-Aboriginal men in rates of sexual recidivism; however, marked group differences persisted in rates of general violent recidivism even after controlling for these covariates. The results support the predictive properties of VRS-SO risk and change scores with treated Canadian Aboriginal sexual offenders.
