The present study examined latent constructs of dynamic sexual violence risk and need, as measured by the Violence Risk Scale-Sexual Offense version (VRS-SO), as a function of Indigenous ancestry among a Canadian federal sample of 1,063 treated men convicted for a sexual offense. Multigroup confirmatory factor analysis of VRS-SO dynamic items ratings supported a correlated 3-factor oblique solution across Indigenous ( = 393) and nonindigenous ( = 670) groups, corresponding broadly to the domains of sexual deviance, criminality, and treatment responsivity. Associations examined between pre- and posttreatment rated factor scores and sexual and violent recidivism were moderated less by Indigenous ancestry and more by victim profile.

The present study sought to develop updated risk categories and recidivism estimates for the Violence Risk Scale-Sexual Offense version (VRS-SO; Wong, Olver, Nicholaichuk, & Gordon, 2003-2017), a sexual offender risk assessment and treatment planning tool. The overarching purpose was to increase the clarity and accuracy of communicating risk assessment information that includes a systematic incorporation of new information (i.e.

This study examined the interrelationship of treatment readiness, responsivity variables, and treatment change to sexual offender treatment outcome, featuring the Treatment Readiness, Responsivity, and Gain Scale: Short Version (TRRG:SV). The sample was composed of 185 Canadian federal offenders who attended a high-intensity sexual offender treatment program and were followed up an average of 9.3 years postrelease.

The present study provides an examination of dynamic sexual violence risk featuring the Stable-2007 (Hanson, Harris, Scott, & Helmus, 2007) and the Violence Risk Scale-Sexual Offender version (VRS-SO; Wong, Olver, Nicholaichuk, & Gordon, 2003) in a Canadian sample of 180 federally incarcerated sexual offenders who attended a high-intensity sexual offender treatment program. Archival pretreatment and posttreatment ratings were completed on the VRS-SO and Stable-2007, and recidivism data were obtained from official criminal records, with the sample being followed up approximately 10 years postrelease. VRS-SO pre- and posttreatment dynamic scores demonstrated significant predictive accuracy for sexual, nonsexual violent, any violent (including sexual), and general recidivism, while Stable-2007 pre- and posttreatment scores were significantly associated with the latter 3 outcomes; these associations were maintained after controlling for the Static-99R (Helmus, Thornton, Hanson, & Babchishin, 2012).

The present study examined the predictive properties of Violence Risk Scale-Sexual Offender version (VRS-SO) risk and change scores among Aboriginal and non-Aboriginal sexual offenders in a combined sample of 1,063 Canadian federally incarcerated men. 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.
