Hyperactive Girls and Boys: Stimulant Drug Effects on Mother-child Interactions

Two doses of Ritalin (0.15 mg/kg and 0.35 mg/kg BID) were evaluated for their differential effects on the mother-child interactions of hyperactive girls and boys. The effects of Ritalin on these interactions were similar for both sexes. During task performance, the children increased their duration of compliance to the tasks. Mothers responded with decreased commands and control over compliance, while increasing their level of more general, non-directive interactions and passive observation of their children. The findings are consistent with previous studies of stimulant drug effects on the social interactions of hyperactive children.
