The authors examined the therapeutic responses of psychopathic sex offenders (>or=25 Psychopathy Checklist--Revised; PCL-R) in terms of treatment dropout and therapeutic change, as well as sexual and violent recidivism over a 10-year follow-up among 156 federally incarcerated sex offenders treated in a high-intensity inpatient sex offender program. Psychopathy and sex offender risk/treatment change were assessed using the PCL-R and the Violence Risk Scale--Sexual Offender version (VRS-SO), respectively. Although psychopathic participants were more likely than their nonpsychopathic counterparts (<25 PCL-R) to drop out, almost 75% of the former completed treatment. Psychopathic offenders who failed to complete sex offender treatment were more likely to violently but not sexually recidivate than completers. Positive treatment changes were associated with reductions in sexual and violent recidivism after psychopathy and sexual recidivism risk were controlled. Overall, the results suggest that given appropriate treatment interventions, sex offenders with significant psychopathic traits can be retained in an institutional treatment program and those showing therapeutic improvement can reduce their risk for both sexual and violent recidivism.
作者们在一个高强度住院性犯罪者项目中，对156名联邦关押的性犯罪者进行了为期10年的随访，从治疗退出率和治疗变化、以及性和暴力再犯情况方面，研究了具有精神病态特征的性犯罪者（心理变态 checklist - 修订版得分≥25；PCL - R）的治疗反应。分别使用PCL - R和暴力风险量表 - 性犯罪者版本（VRS - SO）评估心理变态和性犯罪者风险/治疗变化。尽管具有精神病态特征的参与者比不具有该特征的参与者（PCL - R得分<25）更有可能退出治疗，但前者中近75%完成了治疗。未完成性犯罪者治疗的具有精神病态特征的犯罪者比完成治疗者更有可能实施暴力再犯，但性再犯的可能性并非更高。在控制了心理变态和性再犯风险后，积极的治疗变化与性和暴力再犯率的降低相关。总体而言，结果表明，给予适当的治疗干预，具有明显精神病态特征的性犯罪者可以留在机构治疗项目中，且那些显示出治疗改善的人可以降低其性和暴力再犯的风险。
