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. Efficacy outcomes were measured with the ASRS, and performed at 0, 6, 12, and 16 weeks. RESULTS: The DBT-ST protocol had 81.25% completion rate, with a mean attendance of 87.25% of the sessions. No significant interactions between group and time were detected for outcome measures. DISCUSSION: The DBT-ST was feasible as add-on treatment for adult patients with ADHD in Latin America. Replicating previous findings, DBT-ST has shown no significantly higher improvement in ADHD symptoms in comparison with TaU. Registered at the Clinical Trials database (NCT03326427).

Attention-deficit hyperactivity disorder in ancient Greece: The Obtuse Man of Theophrastus.

We present an ancient Greek description written by the philosopher Theophrastus in his classic book ' Characters' comparable with modern attention-deficit hyperactivity disorder. The arguments are based in one chapter of this book-The Obtuse Man-presenting features of a character closely resembling the modern description of attention-deficit hyperactivity disorder. In a free comparative exercise, we compared Theophrastus descriptions with modern Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) attention-deficit hyperactivity disorder symptoms. The sentences describing The Obtuse Man written by Theophrastus are similar to several symptoms of attention-deficit hyperactivity disorder and he would probably be currently diagnosed with this disorder as an adult. To our knowledge, this is the oldest description compatible with the current conception of attention-deficit hyperactivity disorder in adults in the Western literature. Differently than the moralistic view of ancient Greece regarding those symptoms, the medical attention-deficit hyperactivity disorder conception may be advantageous to patients since it might reduce prejudice and allow individuals to seek treatment.
