title: Prosocial behavior in hyperactive boys: effects of stimulant medication and comparison with normal boys.
abstract: To clarify the effects of stimulant medication on hyperactive (ADHD) children's prosocial as well as aversive behaviors toward peers, 19 hyperactive boys, aged 7-12, were observed as they acted as "leaders" for groups of 2-4 unfamiliar younger children. In a double-blind crossover design, subjects were observed twice, once on placebo and again on a moderate (0.6 mg/kg) dose of methylphenidate (Ritalin). Thirteen comparison boys, without problems in attention and behavior, were also observed in the same leader roles. Relative to comparison boys, hyperactive boys on placebo were more socially engaged, used more aversive leadership techniques, and were rated as less likable by the younger children in their groups. Aversive social behaviors were the strongest predictors of being disliked by the younger children. No differences were found between comparison and unmedicated hyperactive boys for any aspect of prosocial behavior. Stimulant medication had a general dampening effect on social behavior, significantly reducing social engagement and increasing (mild) dysphoria relative to the placebo condition. The implications of these findings for understanding and treating the peer relationship difficulties of hyperactive children are discussed.
