Relative Cognitive Complexity of the Kaufman Assessment Battery for Children (K-ABC) and the WISC-R

Abstract

We evaluated whether abilities measured by the Kaufman Assessment Battery for Children (K-ABC)are as complex as those measured by the Wechsler Intelligence Scale for Children-Revised (WISC-R)within a sample of referred children. Results of factor and multidimensional scaling analyses indicated that abilities tapped by the K-ABC Mental Processing scale are not as complex as those assessed by the WISC-R. K-ABC Achievement scale subtests, however, seemed to assess skills as complex as those measured by many WISC-R subtests. The relative cognitive complexity of the K-ABC and the WISC-R seem comparable, but only when all the K-ABC subtests are administered.
