Testing for multigroup invariance of second-order WISC-IV structure across China, Hong Kong, Macau, and Taiwan

We tested measurement invariance of the WISC-IV second-order factorial structure across China, Hong Kong, Macau, and Taiwan. Both sets of 10 and 14 subtests were tested on standardization samples of children aged 6–16. Results from multi-sample analyses supported measurement invariance, the hypothesized second-order factor model well described data from all four cultures. Overall factor patterns, first- and second-order factor loadings, g variance, residual variances of measured variables, and disturbances of first-order factors of the WISC-IV were invariant among these four cultures.
