CONFIRMATORY FACTOR-ANALYSIS OF THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN - REVISED WITH NORMAL AND PSYCHIATRIC ADOLESCENTS

The Wechsler Intelligence Scale for Children-Revised (WISC-R) has rece ived substantial factor analytic attention. The majority of these stud ies have been exploratory in nature and have supported Kaufman's (1979 ) finding of a three-factor solution. The few confirmatory factor anal ytic studies have provided some support for the three-factor interpret ation over the two- and one-factor interpretations, but they have cons istently failed to examine other potentially valuable models for the W ISC-R. This study tested one, two-, three-, and four-factor models wit hin both normal and psychiatric adolescent inpatient samples. For both samples, the Kaufman three-factor solution emerged with the best over all fit of the WISC-R subtest covariance structure. The remaining mode ls (Guilford-Bannatyne, Bannatyne, Guilford, Horn, and single g) were found to be less applicable to the WISC-R subtest covariance structure and were effectively eliminated as explanatory models when applied to the WISC-R.
