SHORT-FORM OF THE WISC-III FOR CLINICAL USE

Using specific theoretical and practical criteria. 8 subtests were sel ected from the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; D. Wechsler, 1991) to construct a short form that would all ow computation of all 4 factor index scores. Linear scaling was used t o compute deviation quotients of the short form, and confirmatory fact or analysis was used to determine which of 6 hypothesized models could best explain intelligence as measured by this WISC-III short form. Th e results indicated that the short form had satisfactory reliability a nd validity and that a 4-factor model (composed of Verbal Comprehensio n, Perceptual Organization, Freedom From Distractibility, and Processi ng Speed) fit the data of this short form relatively best. Specific gu idelines for use of this short form in clinical practice are provided.
