Outcome of parent-mediated treatment of preschoolers with attention deficit disorder with hyperactivity.

Despite the early onset of attention deficit disorder with hyperactivity (ADDH), there is a dearth of treatment studies with preschoolers with this disorder. Forty-six families with ADDH preschoolers were randomly assigned to either an immediate or a delayed group parent training program aimed at improving child compliance. Groups were balanced on demographic variables. Treatment outcome was evaluated by comparing the groups at pre- and posttreatment and 3-month follow-up on measures of parent-child interactions during free play, a compliance task, and parent-supervised activities, as well as on parent-completed Conners Hyperkinesis Index scores. Positive treatment effect was obtained on measures of compliance, parental style of interaction, and management skills. These improvements were maintained at 3-month follow-up. Evaluation of treatment effects on nontargeted child behaviors indicated no generalization.
