title: Psychostimulant effects on neuropsychological, intellectual, and achievement measures for children and adolescents with Attention Deficit Hyperactivity Disorder.
abstract: This study compared the performance of medicated (n=57) and non-medicated (n=20) subjects with Attention Deficit Hyperactivity Disorder (ADHD) on neuropsychological, intellectual, and achievement measures. The Wechsler Intelligence Scale for Children (Revised or 3rd Edition), appropriate Halstead Reitan Neuropsychological Test Battery, and individual achievement tests were administered to subjects between the ages of 9 and 16 years (M=12.8) Initially, 26 subtest scores were analyzed using multivariate profile analysis. The two groups were found to be parallel (i e, similar in pattern of performance) and coincident (i.e., similar in level of performance). This suggests that the subjects in the two groups displayed a similar pattern of performance on these neuropsychological, intellectual, and achievement measures. The results are discussed in relation to previous research, current etiological models, and the assessment and treatment of ADHD.
