The purpose of this study is to increase physical activity (PA) in children with ADHD using a novel, family-based intervention that promotes PA within the context of evidence-based behavioral management training (BMT) for parents, enhanced with mobile health (mHealth) behavior change strategies. Our first aim is to test the feasibility and acceptability, of an 8-week, family-based, multi-level intervention (BMT-Health) to promote PA in young children with ADHD. Our second aim is to derive an estimate of the effect size of the intervention on PA.
