Objective: Although there is evidence that the positive impact of multisystemic therapy for problem sexual behaviors (MST-PSB) reaches as far as young adulthood, the longer-term effects of MST-PSB into midlife are unknown. The present study examined criminal and civil court outcomes for sexually offending youths who participated on average 24.9 years earlier in a clinical trial of MST-PSB (Borduin et al., Journal of Consulting and Clinical Psychology, 2009, 77, p. 26). Method: Participants were 48 individuals who were originally randomized to MST-PSB or usual community services (UCS) and were at high risk of continued criminality. Arrest, incarceration, and civil suit data were obtained in middle adulthood when participants averaged 39.4 years of age. Results: Intent-to-treat analyses showed that MST-PSB participants had 85% fewer sexual offenses and 70% fewer nonsexual offenses than did UCS participants. In addition, MST-PSB participants were sentenced to 46% fewer days of incarceration and had 62% fewer family-related civil suits. Moreover, the favorable effects of MST-PSB on participants' crimes and civil suits were mediated by improved peer and family relations during treatment. Conclusion: The current study represents the longest and most comprehensive follow-up to date of an MST-PSB clinical trial and demonstrates that the positive effects of an evidence-based youth treatment for sexual crimes can last well into adulthood. Implications of the findings for policymakers, service providers, and researchers are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

多系统疗法对有问题的性行为的长期影响：一项随机临床试验的24.9年随访。

目的：尽管有证据表明，多系统疗法对有问题的性行为（MST-PSB）的积极影响可一直延续到成年后，但尚不清楚MST-PSB对中年人的长期影响。本研究检查了平均早于24.9年参加MST-PSB临床试验的性犯罪青年的刑事和民事法庭结果（Borduin等人，《咨询与临床心理学杂志》，2009年，第77页，第26页）。方法：参与者为48个人，最初被随机分配到MST-PSB或常规社区服务（UCS），并且有继续犯罪的高风险。参与者平均年龄为39.4岁时，在成年中期就获得了逮捕，监禁和民事诉讼数据。结果：意向治疗分析表明，与UCS参与者相比，MST-PSB参与者的性犯罪和非性犯罪的犯罪率分别降低了85％和70％。此外，MST-PSB参与者的监禁天数减少了46％，与家庭有关的民事诉讼减少了62％。而且，MST-PSB对参与者的犯罪和民事诉讼的有利影响是通过治疗期间同伴和家庭关系的改善而实现的。结论：当前的研究代表了迄今为止MST-PSB临床试验中最长，最全面的随访，并表明以证据为基础的青年治疗性犯罪的积极效果可以持续到成年。讨论了研究结果对决策者，服务提供商和研究人员的影响。（PsycInfo数据库记录（c）2021 APA，保留所有权利）。
