Symptomatic improvement in children with ADHD treated with long-term methylphenidate and multimodal psychosocial treatment.
OBJECTIVE To test the hypotheses that in children with attention-deficit/hyperactivity disorder ( ADHD ) ( 1 ) symptoms of ADHD , oppositional defiant disorder , and overall functioning are significantly improved by methylpheni date combined with intensive multimodal psychosocial treatment compared with methylpheni date alone and with methylpheni date plus attention control and ( 2 ) more children receiving combined treatment can be taken off methylpheni date . METHOD One hundred three children with ADHD ( ages 7 - 9 ) , free of conduct and learning disorders , who responded to short-term methylpheni date were r and omized for 2 years to ( 1 ) methylpheni date alone ; ( 2 ) methylpheni date plus psychosocial treatment that included parent training and counseling , social skills training , psychotherapy , and academic assistance , or ( 3 ) methylpheni date plus attention psychosocial control treatment . Assessment s included parent , teacher , and psychiatrist ratings , and observations in academic and gym classes . RESULTS Combination treatment did not lead to superior functioning and did not facilitate methylpheni date discontinuation . Significant improvement occurred across all treatments and continued over 2 years . CONCLUSIONS In stimulant-responsive children with ADHD , there is no support for adding ambitious long-term psychosocial intervention to improve ADHD and oppositional defiant disorder symptoms . Significant benefits from methylpheni date were stable over 2 years
