Factor invariance between genders of the Wechsler Intelligence Scale for Children – Fourth edition

The purpose of this study was to test measurement invariance of the WISC-IV factorial structure between genders. Both 10 and 15 subtest sets were tested on a nationally-representative sample of 2200 children (males N = 1100; females N = 1100). Results from multisample analyses supported partial measurement invariance. Except for a few subtle discrepancies involving correlated error terms, the hypothesized model described the data for both sexes. Overall factor patterns, loadings, unique variances, and factor covariances of the WISC-IV generally did not vary with gender.
