Factor Analysis of the K-WAIS in a Psychiatric Sample

Abstract

This study examined the factor structure of the K-WAIS in a sample of 141 psychiatric patients(ages 16 to 73). The two-factor solution proved more informative and showed the familiar two-factor structure(Verbal Comprehension and Perceptual Organization). Vocabulary, Comprehension, Information, Arithmetic, and Similarity subscales showed strong loadings on Verbal Comprehension factor, whereas all Performance subtests and Digit Span subscale showed strong loadings on Perceptual Organization factor. And, the robustness of an overall intelligence dimension was supported. The first unrotated factor clearly represented general intelligence and all subscales loaded significantly.
