“Beyond Individual Intelligence Tests: Application of Cattell-Horn-Carroll Theory”, 2020-02-06 ():
Cross-battery CFAs of 6 intelligence tests supported a CHC model.
A priori classifications of most of the 66 subtests were accurate.
All 6 CHC broad abilities had strong relations with g but their magnitude varied.
- g and Gf were perfectly correlated and statistically indistinguishable.
The purpose of this study was to examine the applicability of Cattell-Horn-Carroll (CHC) theory across 6 intelligence tests to better understand the cognitive abilities at a broad construct level, as opposed to narrow test level.
Nearly 4,000 youth aged 6–18 were drawn from 7 tests’ standardization and linking samples and missing data techniques were used to complete cross-battery analyses.
Cross-battery confirmatory factor analyses demonstrated support for a CHC model when the Differential Abilities Scales (Second Edition), Kaufman Assessment Battery for Children (Second Edition), Wechsler Intelligence Scale for Children (Third, Fourth, and Fifth Editions), and Woodcock-Johnson III Tests of Cognitive Abilities were analyzed simultaneously. All but one of the 66 subtests mapped on the CHC broad abilities in accordance with prior CHC classifications.
Results: also indicated overall intelligence (g) and fluid reasoning (Gf) were statistically indistinguishable. Findings provide further support that the CHC taxonomy is useful for intelligence test classification, interpretation, and development.
