The efficacy of Acceptance and Commitment Therapy (ACT) has been evaluated in many randomized controlled trials investigating a broad range of target conditions. This paper reviews the meta-analytic evidence on ACT. The 20 included meta-analyses reported 100 controlled effect sizes across n = 12,477 participants. Controlled effect sizes were grouped by target conditions and comparison group. Results showed that ACT is efficacious for all conditions examined, including anxiety, depression, substance use, pain, and transdiagnostic groups. Results also showed that ACT was generally superior to inactive controls (e.g. waitlist, placebo), treatment as usual, and most active intervention conditions (excluding CBT). Weaknesses and areas for future development are discussed.

接受和承诺疗法（ACT）的功效已经在许多调查广泛目标条件的随机对照试验中进行了评估。本文回顾了关于ACT的荟萃分析证据。包含的20项荟萃分析报告了n = 12,477名参与者的100种可控制的效应量。控制效果的大小按目标条件和对照组进行分组。结果表明，ACT对所有检查过的疾病均有效，包括焦虑症，抑郁症，药物滥用，疼痛和转诊组。结果还显示，ACT通常优于不活动的对照组（例如候补名单，安慰剂），照常治疗以及最活跃的干预条件（不包括CBT）。讨论了未来发展的弱点和领域。
