Effects of methylphenidate on aggressive urban children with attention deficit hyperactivity disorder

Determined the efficacy of methylphenidate (MPH) in a clinical population of aggressive, urban children diagnosed with attention deficit hyperactivity disorder (ADHD). In previous studies of prepubertal children with ADHD, MPH has been shown to be effective when compared with placebo. Eighteen inner-city children (ages 6 to 12 years), diagnosed with ADHD and attending a summer treatment program for youth with disruptive behavior disorders, participated in a double-blind placebo trial with assessment data obtained from staff in the program and parents at home. Based on staff ratings of the children's behavior in the program and an academic classroom, the children displayed significant improvements in ADHD symptoms and aggressive behavior with low- and high-dose MPH conditions. At home, parents and guardians reported few significant differences between placebo and MPH on behavior ratings. In both settings, MPH was well tolerated with few side effects found during active drug conditions.
