Predictive Validity of the WISC-R for White and Mexican-American Children.
Reynolds, Cecil R.; Gutkin, Terry B.
Predictive validity of the Weschler Intelligence Scale for Children-Revised (WISC-R), was investigated with 174 Chicanos and 94 Anglos, ages 10-11, who were referred for psychological services. Wide Range Achievement Test Reading, Spelling, and Arithmetic subtest scores were each regressed on WISC-R Verbal, Performance and Full Scale Intelligence Quotients. Regression lines for the prediction of achievement were compared across race through the Potthoff analysis, which provides a simultaneous test of slope and intercept values. As expected, both groups scored substantially below norm on each measure. Subtest correlations were smaller than usual for both groups; they ranged from .03 to .56. Both sets of results were attributed to restriction of range. Of the nine Potthoff comparisons, only one differed significantly. It was concluded that the WISC-R demonstrated predictive validity across race. (Author/CP)
