Group therapy for adolescents with attention-deficit/hyperactivity disorder: a randomized controlled trial.

Objective: To determine the efficacy of group cognitive-behavioral therapy (CBT) on adolescents with attention-deficit/hyperactivity disorder (ADHD) who were in pharmacological treatment but still had persistent symptoms.

Method: We conducted a multicenter, randomized, rater-blinded, controlled trial between April 2012 and May 2014 in a cohort of 119 adolescents (15-21 years of age). Participants were randomly assigned to 12 manualized group CBT sessions (n = 45) or a waiting list control group (n = 44).
