What this study adds The results suggest that among children and adolescents with a diagnosis of ADHD , methylpheni date may improve teacher reported symptoms of ADHD and general behaviour and parent reported quality of life .
Methylpheni date is associated with an increased risk of non-serious but not serious adverse events .
Study question Is methylpheni date beneficial or harmful for the treatment of attention-deficit/hyperactivity disorder ( ADHD ) in children and adolescents ?
Dosage effects of methylphenidate on the social behavior of adolescents diagnosed with attention-deficit hyperactivity disorder.
Research participants were 46 adolescents ( mean age = 13.8 years ) who completed an intensive summer treatment program including a  placebo-controlled , double-blind , crossover trial of 3 doses of methylpheni date ( MPH ) totaling 25 , 50 , or 75 mg per day . Dependent measures focused on social behavior and included observed behavior frequencies and ratings completed by counselors and parents , including side effects . Multiple data analytic methods were used with the goal of ( a ) describing the shape of the dose-response curves across multiple measures of social functioning , ( b ) determining the percentage of adolescents whose social behavior improved in response to MPH , and ( c ) assessing the incremental gains that result from increases in dose . The results show that ( a ) the shape of the dose-response curve is influenced by the measurement method , ( b ) the majority of adolescents exhibited improved social behavior when treated with MPH , ( c ) the bulk of the positive effects of MPH were achieved at the lowest dose , and ( d ) there appear to be diminishing positive effects and an increased risk of negative effects with successively higher doses
