This study assessed the impact of a psychoeducational intervention on family dynamics for couples with children diagnosed with ADHD. Parents participated in 5 weekly sessions that provided information on ADHD and taught cognitive-behavioral strategies and behavior modification techniques. Questionnaires assessed ADHD symptoms, family conflict, and social difficulties before and after the intervention. Results showed decreases in ADHD symptoms, family conflict, and social problems. Parents reported richer relationships with their children and better understanding of their behavior. The psychoeducation program was found to improve family dynamics for those with children diagnosed with ADHD.
