Abstract: | Correlations between the Woodcock-Johnson Test of Cognitive Abilities (WJTCA) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) were evaluated on a sample of 55 behavior disordered males, 28 of whom were also diagnosed as learning disabled. Concurrent validity for this sample was demonstrated by only a 2.33 point difference between the mean WJTCA Broad Cognitive score and the mean WISC-R Full Scale IQ score. Analysis of Pearson product-moment correlations between each WISC-R subtest and each Woodcock-Johnson cluster score substantiated previous assertions that the WJTCA is unduly weighted with Product-Dominant factors. Construct validity of some of the WJTCA clusters also was questioned. Implications of these results for behavior disordered populations were discussed. |
