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).

多系统治疗对问题性行为的长期影响：一项随机临床试验的 24.9 年随访。

目标：虽然有证据表明多系统治疗对问题性行为 (MST-PSB) 的积极影响可以延伸到青年时期，但 MST-PSB 对中年的长期影响尚不清楚。本研究调查了平均提前 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，Journal of Consulting and Clinical Psychology，2009 年，77，第 26 页）。方法：参与者是 48 个人，他们最初被随机分配到 MST-PSB 或普通社区服务 (UCS)，并且处于持续犯罪的高风险中。逮捕、监禁和民事诉讼数据是在参与者平均年龄为 39.4 岁的成年中期获得的。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减少了 85% 和 70%。此外，MST-PSB 参与者被判处的监禁天数减少了 46%，与家庭有关的民事诉讼减少了 62%。此外，MST-PSB 对参与者犯罪和民事诉讼的有利影响是通过治疗期间改善的同伴和家庭关系来调节的。结论：目前的研究代表了 MST-PSB 临床试验迄今为止最长和最全面的随访，并表明以证据为基础的青少年性犯罪治疗的积极影响可以持续到成年。讨论了研究结果对决策者、服务提供者和研究人员的影响。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
