Factor analyses of WISC-R and K-ABC in a Dutch sample of children referred for learning disabilities.
This study examined correlations between WISC-R and K-ABC subtests in a sample of 101 children referred for learning disabilities. A considerable overlap between the two instruments was found. Separate factor analyses of the WISC-R and K-ABC were conducted. By and large, the WISC-R factor structure was similar to that found for standardization samples. Three factors emerged, namely Verbal Comprehension, Perceptual Organization, and Freedom From Distractibility. In line with earlier findings, the K-ABC factor analysis resulted in two factors: Simultaneous and Sequential Processing. A shorter battery combining subtests from both instruments is discussed.
