The Efficacy of Mindfulness-Based Therapies for Attention-Deficit/Hyperactivity Disorder: A Meta-analytic Review

Mindfulness-based therapies (MBT) have been shown to be efficacious in treating internally-focused psychological disorders (e.g., depression), however it is still unclear whether MBT provide improved functioning and symptom relief for individuals with externalizing disorders, including ADHD. In order to clarify the literature on the efficacy of MBT in treating ADHD and to guide future research, an effect size analysis was conducted. A systematic review of studies published in PsycINFO, PubMed, and Google Scholar was completed from the earliest available date until December 2014. A total of eight studies were included in the analysis of inattention and the overall effect size was d= -.72. A total of seven studies were included in the analysis of hyperactivityimpulsivity and the overall effect was calculated at d= -.60. Findings related to changes in executive functioning preand post-intervention were equivocal. Results of this study highlight the possible benefits of MBT in reducing symptoms of ADHD.
