Objective: Despite the prevalence and impact of nonsuicidal self-injury (NSSI), there are few treatments developed to treat the behavior specifically, and little is known about moderators of treatment response. The Treatment for Self-Injurious Behaviors (T-SIB), a brief, behavioral intervention, was developed to treat NSSI in young adults; a previous pilot randomized controlled trial (RCT) comparing T-SIB with treatment as usual (TAU) provided support for the intervention. This study examined demographic, clinical, and NSSI-related predictors of treatment outcome in the pilot RCT for T-SIB. Method: Young adults (N = 33) were randomized to receive T-SIB or treatment as usual; all participants were included in intent-to-treat analyses. The primary outcome of NSSI behaviors was assessed at baseline, posttreatment (9 weeks), and 3-month follow up, and potential moderators were assessed at baseline. Results: Greater lifetime and last year NSSI frequency was associated with fewer NSSI behaviors at posttreatment and follow up among participants in T-SIB. Anxious symptoms also moderated treatment outcomes, but other demographic and clinical variables did not. Conclusion: Previous research has shown that T-SIB is more effective than TAU overall; the current study suggests that T-SIB may be effective for individuals with more frequent NSSI and those with elevated anxiety. A larger evaluation of T-SIB is supported. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

对年轻人非自杀性自伤干预的治疗反应调节剂。

目的：尽管非自杀性自伤 (NSSI) 的流行和影响很大，但很少有专门治疗这种行为的治疗方法，而且对治疗反应的调节剂知之甚少。自伤行为治疗 (T-SIB) 是一种简短的行为干预，旨在治疗年轻人的 NSSI；之前的一项比较 T-SIB 与照常治疗 (TAU) 的试点随机对照试验 (RCT) 为干预提供了支持。本研究在 T-SIB 的试点 RCT 中检查了人口统计学、临床和 NSSI 相关的治疗结果预测因素。方法：年轻人（N = 33）被随机分配接受 T-SIB 或照常治疗；所有参与者都被纳入意向治疗分析。NSSI 行为的主要结果在基线、治疗后（9 周）和 3 个月随访时进行评估，和潜在的调解人在基线时进行了评估。结果：更长的生命周期和去年的 NSSI 频率与 T-SIB 参与者治疗后和随访时更少的 NSSI 行为相关。焦虑症状也缓和了治疗结果，但其他人口统计学和临床​​变量没有。结论：以往的研究表明，T-SIB 总体上比 TAU 更有效；目前的研究表明，T-SIB 可能对 NSSI 更频繁的个体和焦虑升高的个体有效。支持对 T-SIB 进行更大的评估。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。焦虑症状也缓和了治疗结果，但其他人口统计学和临床​​变量没有。结论：以往的研究表明，T-SIB 总体上比 TAU 更有效；目前的研究表明，T-SIB 可能对 NSSI 更频繁的个体和焦虑升高的个体有效。支持对 T-SIB 进行更大的评估。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。焦虑症状也缓和了治疗结果，但其他人口统计学和临床​​变量没有。结论：以往的研究表明，T-SIB 总体上比 TAU 更有效；目前的研究表明，T-SIB 可能对 NSSI 更频繁的个体和焦虑升高的个体有效。支持对 T-SIB 进行更大的评估。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
