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.
