Feasibility trial of the dialectical behavior therapy skills training group as add-on treatment for adults with attention-deficit/hyperactivity disorder.

Objective: Our aim was to explore the feasibility, and efficacy of a Dialectical Behavior Therapy Skill Training Group (DBT-ST) as an add-on treatment for adult attention-deficit/hyperactivity disorder (ADHD) in Latin America.

Method: Adults with ADHD (n = 31) with stable medication treatment for ADHD and residual symptoms (ASRS > 20) were randomly assigned to DBT-ST (n = 16) or treatment as usual (TaU; n = 15) for 12 weeks. Feasibility was accessed by attendance and completion rates at 12 weeks.
