Bowden, Stephen C.; Saklofske, Donald H.; Weiss, Lawrence G. – Assessment, 2011
Examination of measurement invariance provides a powerful method to evaluate the hypothesis that the same set of psychological constructs underlies a set of test scores in different populations. If measurement invariance is observed, then the same psychological meaning can be ascribed to scores in both populations. In this study, the measurement…

Holdnack, James A.; Zhou, Xiaobin; Larrabee, Glenn J.; Millis, Scott R.; Salthouse, Timothy A. – Assessment, 2011
The Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and the Wechsler Memory Scale-fourth edition (WMS-IV) were co-developed to be used individually or as a combined battery of tests. The independent factor structure of each of the tests has been identified; however, the combined factor structure has yet to be determined. Confirmatory…

Egeland, Jens; Bosnes, Ole; Johansen, Hans – Assessment, 2009
Confirmatory Factor Analyses (CFA) of the Wechsler Adult Intelligence Scale-III (WAIS-III) lend partial support to the four-factor model proposed in the test manual. However, the Arithmetic subtest has been especially difficult to allocate to one factor. Using the new Norwegian WAIS-III version, we tested factor models differing in the number of…

Gignac, Gilles E. – Assessment, 2005
Past attempts to model via confirmatory factor analysis (CFA) the Wechsler Adult Intelligence Scale-Revised (WAIS-R) intersubtest covariation have used an oblique factor or a higher order modeling approach. The attempts have failed to yield adequate model fit, based on current CFA recommendations. Using the WAIS-R standardization data, it is…

Kaufman, Alan S.; And Others – Assessment, 1994
Data from 255 normal individuals were factor analyzed. Variables included subtests from the Wechsler Adult Intelligence Scale-Revised (WAIS-R), the Kaufman Adolescent and Adult Intelligence Test (KAIT), and two new brief measures. Results are interpreted in the context of previous Horn analyses of the KAIT and WAIS-R. (SLD)
