The Efficacy of Parent-Child Interaction Therapy (PCIT) for Youth with Attention-Deficit/Hyperactivity Disorder (ADHD): A Meta-Analysis.

Attention-deficit/hyperactivity disorder (ADHD) is highly prevalent in early childhood and has long-term negative effects when left untreated. Parent-Child Interaction Therapy (PCIT) is an early intervention for children aged 2- to-7-years that has extensive evidence for treating child externalizing problems by teaching parents effective strategies to manage child behavior. However, the effect of PCIT for families with children diagnosed with ADHD is not completely understood. This meta-analysis aims to synthesize research on the use of PCIT for children with ADHD. Nine out of 711 identified studies were analyzed. Summary effect sizes were calculated using the standardized mean gain for child ADHD symptoms, child behaviors, parent stress, and parenting behaviors, and the Fail-Safe N was calculated to determine the robustness of the results. Overall, PCIT had a significant beneficial effect on child ADHD symptoms (g = 0.90), child behavior (g = 0.44), parent stress (g = 0.82), and parenting behaviors (g = 2.15). Results of this meta-analysis suggest that PCIT is an effective treatment for reducing core symptoms of ADHD.
