Abstract: | The reliability and predictive validity of the WPPSI was investigated with a sample of lower SES Mexican-American children. Reliability was determined using split-half procedures parallel to those reported in the test manual. Predictive validity was determined by correlating WPPSI scores with scores from the Metropolitan Reading Test. The results revealed that the WPPSI has high reliability, as determined by internal consistency procedures, but validity coefficients were not significant. These results suggest that the WPPSI may be inappropriate for special program placement purposes with this population. |
