Executive Control Training for Adolescents With ADHD: A Randomized Controlled Effectiveness Trial

The goal of this clinical trial is to evaluate an evidence-based, non-pharmacological treatment alternative: Goal Management Training (GMT) for adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD). The main questions we aim to answer are: 1. Is GMT more effective than Treatment as Usual (TAU) in improving executive functioning in adolescents with ADHD? 2. Is GMT more effective than TAU in improving emotional health and social functioning in adolescents with ADHD? 3. Which clinical or cognitive characteristics are associated with treatment response? 4. Do medication, age, gender, and functional status at intake influence treatment response and long-term outcomes? 5. Are genetic (e.g. polygenic risk scores) and brain imaging data (e.g. estimates of brain maturation based on structural MRI or resting-state functional magnetic resonance imaging (fMRI) brain connectivity) relevant clinical predictors for treatment response and long-term outcomes?
