The Effectiveness of Acceptance and Commitment Therapy (ACT) for Insomnia Disorder: A Meta-Analysis of Randomized Controlled Trials
Abstract
Acceptance and Commitment Therapy (ACT) has gained attention as a potential treatment for insomnia disorder, offering a unique approach that targets underlying processes contributing to sleep difficulties. This meta-analysis of randomized controlled trials (RCTs) evaluates the efficacy of ACT in reducing insomnia symptoms and improving sleep quality. Through a comprehensive review of the literature, the meta-analysis synthesizes effect sizes from RCTs assessing the effectiveness of ACT compared to control conditions (e.g., sleep hygiene education, relaxation techniques) in targeting insomnia-related outcomes, including sleep onset latency, wake after sleep onset, total sleep time, and sleep efficiency. Additionally, it examines potential moderators of treatment outcomes, such as intervention duration, mode of delivery (individual vs. group), therapist involvement, and participant characteristics (e.g., age, comorbidities), to better understand the factors influencing the effectiveness of ACT for insomnia disorder.
