抄録

The cases with attention deficit/hyperactivity disorder (AD/HD) are known to have difficulties in performing various neuropsychological tests related to the executive function. Among them, the Wisconsin Card Sorting Test (WCST) is already applied to many children with AD/HD. There are, however, differences in the measurement of WCST, and also in the background conditions of the patients, such as the status of medication and the level of Intelligence Quotient (IQ), and presumably as a result, the outcome of WCST shows a diversity. The Keio version WCST (KWCST) is a modified WCST by reducing the number of cards and presenting subjects in two steps separated by a short pause, during which a brief instruction is given. This study was undertaken to compare the performances of children with AD/HD to normal controls using KWCST according to full-scale IQ (FIQ) and also the subtypes of AD/HD. Subjects in this study were 21 unmedicated children with AD/HD, ranging from 5 to 15 years of age, and 21 normal controls who were matched on sex and age. Children with AD/HD whose FIQ was above 80 showed significant low scores in such indices as categories achieved (CA), total errors (TE), and nonperseverative errors of Nelson (NPEN) in the second step. As to the analysis according to the subtypes, the predominantly inattentive type showed significant low scores in CA, TE and NPEN of the second step, while the combined and predominantly hyperactive-impulsive types showed no significant differences compared with the normal controls. These results suggest that patients with AD/HD have difficulties in effectively utilizing their experiences in the first step as well as instructions which are given before the second step, and also indicate the importance of the second step from a view of the clinical applications.
