The purpose of this study was to explore the ability of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991a) to discriminate between a group of children classified with ADHD (n = 40) and a group of non-ADHD children (n = 40), as well as to identify which combination of WISC-III subtests resulted in the highest level of correct classifications. A stepwise discriminant function analysis indicated that four WISC-III subtests contributed significantly to the prediction of group membership: Digit Span, Information, Vocabulary, and Picture Completion. An overall classification rate of approximately 89% was attained when the four WISC-III subtests were included in the equation. Ninety percent of the children classified as ADHD and 87.5% of the non-ADHD children were correctly identified when using the four WISC-III subtests as predictors.
