Examined the factor structure of the Wechsler Adult Intelligence Scale-Revised (WAIS-R) in a sample of 200 medical patients and 271 psychiatric patients. Results indicate the WAIS-R has a robust factor structure and provide evidence of Verbal, Performance, and Freedom From Distractability factors in psychiatric and medical populations. (Author/BH)

Determined the factoral strucuture of the Wechsler Adult Intelligence Scale-Revised in a clinical sample (N=85) receiving vocational counseling and compared this structure to that reported by Silverstein (1982) for the normative group. Results showed a high rate of consistency with those reported by Silverstein. (LLL)

Subjected the standardization data for the Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the original Wechsler Adult Intelligence Scale (WAIS) to principal-factor analysis. A two-factor solution was adopted for each scale. The stability of the two factors, Verbal Comprehension and Perceptual Organization, was high both within and between…

A regression equation relating verbal and full-scale IQs was derived from scores of patients. Scores were highly correlated, and verbal IQ significantly exceeded full-scale IQ. Regression estimates closely estimated mean full-scale IQ, suggesting that the verbal scale serves effectively as a WAIS abbreviation. (Author)

Obtained a hierarchical factor solution on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) subtest intercorrelations for the nine age groups included in the standardization sample. Findings support the validity of the WAIS-R as a measure of general intelligence and the validity of maintaining separate Verbal and Performance IQs. (Author)

Factor analyzed the Wechsler Adult Intelligence Scale-Revised (WAIS-R) across nine age groups in the standardization sample. When three- and four-factor analyses were performed, the familiar three-factor structure (Verbal Comprehension, Perceptual Organization, and Freedom From Distractibility) was clearly visible.
