title: [Clinical application of the modified Stroop test to children with attention deficit/hyperactivity disorder].
abstract: The Stroop test has been already applied to many children with attention deficit/hyperactivity disorder (AD/HD). There are, however, differences in the measurement of the Stroop test, and also in the background conditions of the patients, such as the status of comorbidity with learning disorder (LD), medication and the level of Intelligence Quotient (IQ), and presumably as a result, the outcome of the Stroop test shows a diversity. This study was undertaken to compare the performances of children with AD/HD to normal controls using the modified Stroop test according to the subtypes of AD/HD. Subjects in this study were 23 unmedicated children with AD/HD, ranging from 6 to 14 years of age, and 69 normal controls who were matched on sex and age. Children with AD/HD whose verbal IQ and performance IQ were above 80 showed significant differences in such indices as Incongruent Color Naming time (ICN) and the resulting index of subtracting Color Naming time (CN) from ICN (ICN-CN). As to the analysis according to the subtypes excluding 8 cases with comorbid LD, both the predominantly inattentive type and the group putting together the predominantly hyperactive-impulsive type and the combined type showed significant differences in ICN--CN compared with the normal controls. These results suggest that the inattentiveness relevant factor affects the performance of the interference task in children with AD/HD.
