Confirmatory factor analyses of the third edition of the Wechsler Intelligence Scale for Children (WISC-III) using the Canadian normative sample (n=1,100 children) were conducted to verify the four-factor model found in the U.S. normative sample. Results paralleled those of the U.S. sample and support use of the WISC-III factor indexes. (SLD)

Inspection of the factor structure of the Wechsler Intelligence Scale for Children-III for four age groups from the standardization sample indicated a hierarchical arrangement of abilities when both two-factor and four-factor solutions were used. Both solutions indicated a strong general intelligence factor at all age levels studied. (SLD)

The criterion validity of the factor index scores of the third edition of the Wechsler Intelligence Scale for Children (WISC-III) was evaluated in a sample of 88 children with traumatic head injury. Only the Perceptual Organization and Processing Speed scores demonstrated acceptable sensitivity to injury severity for evaluation use. (SLD)

The Wechsler Intelligence Scale for Children-Third Edition (WISC-III) was factor analyzed with a sample of 106 deaf and hard-of-hearing children. Two factors emerged, labeled "Language Comprehension" and "Visual-Spatial Orientation." Implications and future directions for the assessment of deaf and hearing-impaired students are…

The factor structures of the 10 Wechsler Intelligence Scale for Children-III core subtests were studied with 161 black students receiving special education services. Results provide evidence of a large first principal factor as well as the expected verbal and performance factors. Implications for psychologists are discussed. (SLD)

Two studies involving 89 children were conducted to evaluate the validity of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) with African American students undergoing special education evaluations. Results were highly correlated with previously determined IQs, and the factor structure of the WISC-III was generally supported.…

Procedures recommended in the Wechsler Intelligence Scale for Children (Third Edition) (WISC-III) manual for factorial estimation may be replaced by new methods using the computer and a spreadsheet program. Constants and formulas needed to draft a spreadsheet program for estimating the factors using WISC-III scaled scores are presented. (SLD)

The Wechsler Intelligence Scale for Children (WISC) has a long history, dating back to the 1930s, when it was devised specifically for measuring the intelligence of children through verbal and performance subtests. Intelligence quotients (IQs) are developed for verbal and performance skills. The subtests, their factors, indices derived from them,…
