Enduring the tests of age and time: Wechsler constructs across versions and revisions

The Wechsler scales are some of the most commonly used intelligence tests in research and practice. It is unknown whether different versions (i.e., WPPSI, WISC, and WAIS) or revisions (e.g., WISC-IV and WISC-V) of the Wechsler scales measure the same constructs. We tested the factorial invariance across six Wechsler scales (WPPSI-III, WPPSI-IV, WISC-IV, WISC-V, WAIS-III, and WAIS-IV) to investigate whether the constructs measured across these...
