Attention-deficit Hyperactivity Disorder (ADHD) is the most commonly diagnosed behavior disorder among children in the United States. A frequently used and effective intervention for ADHD involves parent training for behavioral management. While parent training improves child compliance, parent-child interactions, and parenting skills, the effects of behavioral parent training on school behavior remain unclear. This study examines the effects of behavioral parent training on the behavior of ADHD children and their parents. The study sought to know whether conjoint behavioral consultation (CBC) enhanced behavioral parent training effects. Fourteen sets of parents with ADHD children participated in a 7-week behavioral parent training class. After the training class, four parent-child-teacher triads took part in follow-up CBC. All parents reported improved parental ratings of their own parenting skills as well as increased compliance in their children. Results also indicated that the addition of CBC, following behavioral parent training, resulted in further positive behavioral changes. The study draws three general conclusions: (1) behavioral parent training improves the behavior of ADHD children in the home; (2) behavioral parent training effects do not generalize to the school setting; and (3) CBC can promote generalization across settings as well as foster closer home-school collaboration and cooperation.
