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, M\u00e9tis, 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.<\/jats:p>","DOI":"10.1177\/1079063216649594","type":"journal-article","created":{"date-parts":[[2016,5,17]],"date-time":"2016-05-17T21:15:03Z","timestamp":1463519703000},"page":"254-275","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":31,"title":["Predictive Accuracy of Violence Risk Scale\u2013Sexual Offender Version Risk and Change Scores in Treated Canadian Aboriginal and Non-Aboriginal Sexual Offenders"],"prefix":"10.1177","volume":"30","author":[{"given":"Mark E.","family":"Olver","sequence":"first","affiliation":[{"name":"University of Saskatchewan, Saskatoon, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justina N.","family":"Sowden","sequence":"additional","affiliation":[{"name":"Correctional Service of Canada, Saskatoon, Saskatchewan, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Drew A.","family":"Kingston","sequence":"additional","affiliation":[{"name":"Royal Ottawa Health Care Group, Ottawa, Ontario, Canada"},{"name":"University of Ottawa, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terry P.","family":"Nicholaichuk","sequence":"additional","affiliation":[{"name":"University of Saskatchewan, Saskatoon, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey","family":"Gordon","sequence":"additional","affiliation":[{"name":"University of Saskatchewan, Saskatoon, Canada"},{"name":"Correctional Service of Canada, Saskatoon, Saskatchewan, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah M.","family":"Beggs Christofferson","sequence":"additional","affiliation":[{"name":"University of Canterbury, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen C.
