| Abstract: | Correlations between the WISC-R, the Woodcock-Johnson Achievement clusters, the Woodcock-Johnson Aptitude clusters, and the Broad Cognitive Ability Score were evaluated, using as a sample 60 BD male adolescents. Aptitude cluster scores were found to have insufficient validity to justify computation for such a population. The Broad Cognitive Ability Score was found to be significantly correlated to all W-J Achievement cluster scores. Implications were discussed of Hotelling's t-test analyses examining the correlations between the four W-J Achievement cluster scores and the WISC-R VIQ as compared to the four W-J Achievement cluster-Broad Cognitive Ability correlations. |
