Structural validity of the Indonesian Version Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V-ID): Exploratory and confirmatory factor analyses.

The Indonesian Version Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V-ID) has recently been adapted for use in Indonesia. Because evidence based on internal structure is essential for supporting the interpretation of test scores in adapted instruments, this study examined the factor structure of the 16 WISC-V-ID subtests using exploratory factor analysis and confirmatory factor analysis. Participants were 1,508 Indonesian children aged 6-16 years drawn from the WISC-V-ID norming sample, providing a large and regionally diverse representation of the target population. Exploratory factor analysis results supported a four-factor solution, whereas the five-factor solution was not satisfactory. The findings also indicated that the Picture Concepts subtest functioned poorly in the Indonesian adaptation. Confirmatory factor analysis results showed that both the four- and five-factor higher order models fit the data adequately. However, the five-factor model revealed construct redundancy between the general factor (g) and the Fluid Reasoning factor, limiting the interpretability of that structure. This problem was resolved when the Picture Concepts subtest was excluded. Additional confirmatory factor analysis supported the structural plausibility of the general ability, cognitive proficiency, and nonverbal indexes as broad ancillary composites, although the general ability and cognitive proficiency indexes shared substantial variance. These findings suggest that the 15-subtest configuration provides the theoretically best-supported and practically most useful structural representation of the WISC-V-ID while also offering new evidence regarding the structural validity of the WISC-V in an Asian context.
