The Violence Risk Scale-Sexual Offender version (VRS-SO) is a rating scale designed to assess risk and predict sexual recidivism, to measure and link treatment changes to sexual recidivism, and to inform the delivery of sexual offender treatment. The VRS-SO comprises 7 static and 17 dynamic items empirically or conceptually linked to sexual recidivism. Dynamic items with higher ratings identify treatment targets linked to sexual offending. A modified stages of change model assesses the offender's treatment readiness and change. File-based VRS-SO ratings were completed on 321 sex offenders followed up an average of 10 years post-release. VRS-SO scores predicted sexual and nonsexual violent recidivism post-release and demonstrated acceptable interrater reliability and concurrent validity. A factor analysis of the dynamic items generated 3 factors labeled Sexual Deviance, Criminality, and Treatment Responsivity, all of which predicted sexual recidivism and were differentially associated with different sex offender types. The dynamic items together made incremental contributions to sexual recidivism prediction after static risk was controlled for. Positive changes in the dynamic items, measured at pre- and posttreatment, were significantly related to reductions in sexual recidivism after risk and follow-up time were controlled for, suggesting that dynamic items are indeed dynamic or changeable in nature.
暴力风险量表-性犯罪者版本（VRS-SO）是一种评定量表，旨在评估风险并预测性再犯，衡量治疗变化与性再犯之间的关联，并为性犯罪者治疗的实施提供参考。VRS-SO由7个静态项目和17个动态项目组成，这些项目在经验或概念上与性再犯相关。评分较高的动态项目可确定与性犯罪相关的治疗目标。一种经过修改的改变阶段模型可评估犯罪者对治疗的准备情况和改变情况。基于档案的VRS-SO评分是对321名性犯罪者完成的，这些犯罪者在释放后平均随访了10年。VRS-SO分数可预测释放后的性暴力和非性暴力再犯情况，并显示出可接受的评分者间信度和同时效度。对动态项目进行的因素分析产生了3个因素，分别标记为性偏差、犯罪行为和治疗反应性，所有这些因素都可预测性再犯，并且与不同类型的性犯罪者存在不同的关联。在控制了静态风险后，动态项目共同对性再犯预测做出了增量贡献。在控制了风险和随访时间后，治疗前和治疗后测量的动态项目的积极变化与性再犯的减少显著相关，这表明动态项目在本质上确实是动态的或可改变的。
