Factor structure of the WISC-R with Anglos and Mexican-Americans

The present study compared the underlying factor structure of the Wechsler Intelligence Scale for Children-Revised for Anglo and Mexican-American children. Subtests of the WISC-R were administered to 109 Anglo and 123 Mexican-American children ranging from 8 to 15 years of age and were analyzed separately for each group. Three factors emerged for each ethnic classification which corresponded closely to those usually reported for the WISC-R. Coefficients of congruence (.84–.89) between factors given the same name for each ethnic group indicated a high degree of similarity in constructs being measured.
