Investigation of the Verbal/Nonverbal Structure of the Woodcock-Johnson: Implications for Subtest Interpretation and Comparisons with the Wechsler Scales
The Woodcock-Johnson (WJ) is a relative new-comer on the assessment scene that has generated significant interest. Cognitive mean score differences with the WISC-R have been reported, and a number of hypotheses have been advanced to explain this difference. Possible differences in verbal/nonverbal factor structure were investigated via exploratory factor analysis of the WJ norm intercorrelation tables. Both a Verbal and Nonverbal factor were extracted, and comparisons with similar WISC-R factor data suggest both similarities and differences. Grade analysis also suggests that the abilities tapped by certain WJ subtests may vary due to developmental factors.
