Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are known to experience difficulty in peer relationships. Neither standard interventions for ADHD nor peer acceptance-oriented interventions fully remedy this problem. We propose that interventions targeting ADHD children's dyadic friendships may be more realistic strategies for improving peer relationships. Hence, a friendship intervention, implemented within the context of an intensive behavioral treatment program with 209 ADHD children, is described. A model is proposed in which the friend's antisocial behavior relates to parental compliance with the friendship intervention, and both the friend's antisocial behavior and parental compliance predict friendship quality and treatment response. Results indicate that children paired with peers lower on antisocial behavior and children whose parents had higher levels of compliance with the friendship intervention achieved higher quality friendships and were rated by teachers as more improved.
