“…No significant differences were found in this study between the standardization samples on VC, FR, WM, and PS factors, suggesting that no real differences exist between the A&NZ and U.S. samples on these broad abilities. While the difference in the VS across females between A&NZ and U.S. samples was small, and overall equality of latent means was found, a small difference can lead to a meaningful difference in classifications of people, especially at the extremes of the distribution of scores (Sudarshan & Bowden, 2021).…”

Measurement invariance underlies construct validity generalization in psychology and must be demonstrated prior to any cross-population comparison of means and validity correlations. The purpose of this study was to evaluate the measurement invariance of the Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V) across Australia and New Zealand (A&NZ) versus the U.S. normative samples. The WISC-V is the most widely used assessment of intelligence in children. Participants were census matched, nationally representative samples from A&NZ (n = 528) and the United States (n = 2,200) who completed the WISC-V standardization version. Baseline model estimation was conducted to ensure the same model showed acceptable fit in both samples separately. Measurement invariance was then examined across A&NZ and United States. The five-factor scoring model described in the test manual showed excellent fit in both samples. Results showed that the WISC-V demonstrated strict metric measurement invariance across the A&NZ and U.S. samples. Further, the results were consistent with the Cattell-Horn-Carroll (CHC) framework of cognitive abilities, indicating the generalizability of cognitive abilities across cultures. Small but significant differences in visual spatial latent means were found across females, highlighting the importance of local normative data. These findings suggest that the WISC-V scores can be meaningfully compared across A&NZ and United States and that the constructs, which align with CHC theory, and associated construct validity research, generalize across countries. Public Significance StatementThis study examined the generalizability of the WISC-V, the most widely used intelligence test for children, across nationally representative samples from A&NZ and the United States. The results suggest that WISC-V scores can be meaningfully compared across A&NZ and U.S. children and that the psychological constructs measured by the WISC-V generalize across countries. However, small mean score differences highlight the importance of local normative data.

ObjectivesThis study examined the factorial invariance of the factor structure of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC‐V) across the UK, US and Australia & New Zealand (A&NZ). The factorial equivalence of cognitive assessments should be demonstrated before assuming cross‐culture generalizability and interpretations of score comparisons.MethodsData were obtained from the UK, US and A&NZ normative standardizations of the WISC‐V. The samples consisted of 415 UK, 2200 US and 528 A&NZ children, aged 6–16. Confirmatory factor analysis was applied separately in each sample to establish the baseline model. Next, tests of factorial invariance were undertaken using the recommended hierarchical approach, firstly across the UK and A&NZ samples and then across the UK and US samples.ResultsThe five‐factor first‐order scoring model was found to be excellent fit across all three samples independently. Strict factorial invariance of the WISC‐V was demonstrated firstly across the UK and A&NZ and secondly the UK and US nationally representative standardization samples. Comparison of latent means found small but significant differences in female children across the UK and A&NZ samples.ConclusionsConsistent with previous research, these results demonstrate the generality of the WISC‐V factor structure across the UK, US and A&NZ. Furthermore, as the WISC‐V factor structure aligns with the Cattell–Horn–Carroll (CHC) model of cognitive abilities, the results add further support to the cross‐cultural generalizability of the CHC model. Small but significant differences in latent factor scores found across samples support the development and use of local normative data.
