Weiss, Lawrence G.; Keith, Timothy Z.; Zhu, Jianjun; Chen, Hsinyi – Journal of Psychoeducational Assessment, 2013
The purpose of this study was to determine the constructs measured by the WISC-IV and the consistency of measurement across large normative and clinical samples. Competing higher order four- and five-factor models were analyzed using the WISC-IV normative sample and clinical subjects. The four-factor solution is the model published with the test…

Canivez, Gary L. – School Psychology Quarterly, 2011
Orthogonal higher-order factor structure of the Cognitive Assessment System (CAS; Naglieri & Das, 1997a) for the 5-7 and 8-17 age groups in the CAS standardization sample is reported. Following the same procedure as recent studies of other prominent intelligence tests (Dombrowski, Watkins, & Brogan, 2009; Canivez, 2008; Canivez &…

Canivez, Gary L.; Watkins, Marley W. – School Psychology Quarterly, 2010
The factor structure of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV; Wechsler, 2008a) with the adolescent participants (ages 16-19 years; N = 400) in the standardization sample was assessed using exploratory factor analysis, multiple factor extraction criteria, and higher-order exploratory factor analyses. Results from…

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)

Taub, Gordon E. – Practical Assessment, Research & Evaluation, 2001
Investigated the construct validity of the implied and theoretical structures of the Wechsler Adult Intelligence Scale-III (WAIS-III). Results using the standardization sample of 2,450 adults and adolescents indicate that the WAIS-III provides an excellent measure of the four-factor model and a general factor, but they do not support the construct…
