OBJECTIVE To assess the effectiveness of noninstitutional psychosocial interventions in preventing recidivism among criminal adolescents. METHOD We performed a systematic review and meta-analysis of randomized and nonrandomized controlled trials assessing the impact on recidivism among juveniles aged 12-17. The included studies had a low to medium risk of bias and were published between 2000 and 2019. Standardized mean differences or risk differences were calculated. RESULTS We included 35 (20 randomized, 15 nonrandomized) studies evaluating 17 unique, noninstitutional psychosocial interventions. A meta-analysis found no significant reductions in recidivism for studied interventions compared to control conditions. Although single studies suggested some positive effects, the evidence provided by these studies was found to have very low certainty. Post hoc analyses indicated that studies including a low-intensity control condition might have stronger relative intervention effects compared to studies with medium or high-intensity control conditions. CONCLUSION This systematic review did not find any one noninstitutional psychosocial intervention to be more effective than control treatments in reducing future criminality among juvenile offenders aged 12-17. We discuss the implications of the present findings for social work and child and adolescent psychiatry practices. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

对预防青少年犯罪累犯的非机构心理社会干预措施的系统回顾和荟萃分析。

目的 评估非机构心理社会干预措施在预防青少年犯罪累犯方面的有效性。方法 我们对随机和非随机对照试验进行了系统回顾和荟萃分析，评估了对 12-17 岁青少年累犯的影响。纳入的研究具有低至中等偏倚风险，并于 2000 年至 2019 年之间发表。计算了标准化平均差异或风险差异。结果 我们纳入了 35 项研究（20 项随机研究，15 项非随机研究），评估了 17 种独特的非机构心理社会干预措施。荟萃分析发现，与对照条件相比，研究干预措施的累犯率没有显着减少。尽管个别研究表明了一些积极的影响，但这些研究提供的证据被发现具有非常低的确定性。事后分析表明，与采用中或高强度控制条件的研究相比，采用低强度控制条件的研究可能具有更强的相对干预效果。结论 本系统评价没有发现任何一种非机构心理社会干预措施在减少 12-17 岁青少年罪犯未来犯罪方面比对照治疗更有效。我们讨论当前研究结果对社会工作以及儿童和青少年精神病学实践的影响。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
