A Systematic Review and Meta-analysis of Parent Training for Disruptive Behavior in Children with Autism Spectrum Disorder

Parent training (PT) has emerged as a promising treatment for disruptive behavior in children with autism spectrum disorder (ASD). This review summarizes the essential elements of PT for disruptive behavior in children with ASD and evaluates the available evidence for PT using both descriptive and meta-analytic procedures. We searched Medline, PsycINFO, and PubMed databases (1980–2016) in peer-reviewed journals for randomized controlled trials (RCTs) of PT for disruptive behavior in children with ASD. The systematic search of 2023 publications yielded eight RCTs involving a total of 653 participants. We calculated effect sizes using either raw post-treatment means and standard deviations for each treatment group (PT and control) or group mean differences with associated 95% confidence intervals (CIs). Differences in post-treatment means were converted to a standardized difference in means (SMD) for each primary outcome. Results support the efficacy of PT for disruptive behavior in children with ASD, with a SMD of −0.59 [95% CI (−0.88, −0.30); p
