Cross-National Generalizability of WISC-V and CHC Broad Ability Constructs across France, Spain, and the US

The Cattell–Horn–Carroll (CHC) model is based on psychometric cognitive ability research and the most empirically supported of constructs. This study one in a series cross-national comparisons investigating equivalence generalizability psychological constructs which align with CHC model. Previous exploring cross-cultural measures concluded that factor analytic models abilities generalize across cultures are compatible well-established constructs, as measured by Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V), has been established English-speaking samples. However, few studies have explored non-English speaking, nationally representative WISC-V five-factor standardization samples from France, Spain, US. scoring demonstrated excellent fit three independently. Factorial invariance was investigated results strict factorial provide further support Western cultural populations speak different languages continued use development common nomenclature blueprint researchers test developers.
