The objectives of this study were twofold: to show the efficacy of a cognitive-behavioral self-control therapy on children with ADHD and to determine whether the combination of training in selfcontrol with training in anger management has better outcomes on two subgroups of hyperactive children, aggressive and nonaggressive. Thirty-two children with ADHD, 16 aggressive and 16 nonaggressive, participated in the research. We applied a cognitive-behavioral self-control training, which included self-instructional training via modeling and behavioral contingencies, to 16 of the 32 hyperactive children. The other 16 hyperactive children were taught the same program, but combined with anger management training. The interventions were carried out by two therapists each taking care of four groups, one of each in the following conditions: hyperactive with the cognitive-behavioral self-control therapy, hyperactive with the combined treatment, hyperactive-aggressive with the cognitive-behavioral self-control therapy, and hyperactive-aggressive with the combined treatment. The results indicated important improvements on several measures in all treated groups. Furthermore the improvements of children with aggressiveness were slightly better, according to the parents, with the combined treatment than without it. The data provide support for including anger management training in the cognitive-behavioral interventions for hyperactive-aggressive students.
