This study utilized confirmatory factor analyses to examine the latent factor structure of the Wechsler Intelligence Scale for Children--Fourth Edition, Italian adaptation (WISC-IV Italian) standardization sample. One through five, oblique first-order factor models and higher-order as well as bifactor models were examined and compared using CFA.…

The construct validity of the Spanish Version of the Wechsler Intelligence Scale for Children Fifth Edition (WISC-V[superscript Spain]) was investigated via confirmatory factor analysis. For all 15 subtests, the higher-order model preferred by Wechsler (2015b) contained five group factors but lacked discriminant validity. A bifactor model with…

Background: There is inadequate information regarding the factor structure of the Wechsler Intelligence Scale for Children -- Fifth UK Edition (WISC-V[superscript UK]; Wechsler, 2016a, Wechsler Intelligence Scale for Children-Fifth UK Edition, Harcourt Assessment, London, UK) to guide interpretation. Aims and methods: The WISC-V[superscript UK]…

This study further examined the Gifted Rating Scales (GRS) at the internal and external stages of test validation by (a) testing structural fidelity as indicated by the number of factors supported as well as the correspondence of the latent factor structure with the scoring model proposed by the authors and (b) examining the external relations of…

The Wechsler Intelligence Scale for Children--Fourth Edition (WISC-IV) is one of the most frequently used intelligence tests in clinical assessments of children with learning difficulties. Construct validity studies of the WISC-IV have generally supported the higher order structure with four correlated first-order factors and one higher-order…

Irish educational psychologists frequently use the Wechsler Intelligence Scale for Children-Fourth U.K. Edition (WISC-IV[superscript UK]) in clinical assessments of children with learning difficulties. Unfortunately, reliability and validity studies of the WISC-IV[superscript UK] have not yet been reported. This study examined the construct…

The structure of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV; D. Wechsler, 2003a) was analyzed via confirmatory factor analysis among a national sample of 355 students referred for psychoeducational evaluation by 93 school psychologists from 35 states. The structure of the WISC-IV core battery was best represented by four…

Uses both exploratory (EFA) and confirmatory factor analyses (CFA) to examine the factor structure of the WISC-III among White and Black students from the WISC-III standardization sample and a sample of 348 Black students referred for psychological evaluation. Results of the EFA provided evidence of a large first principal factor as well as the…

Analyzes the longitudinal factor structure of the WISC-III for both configural and metric invariance with a group of 177 students with disabilities. Concludes that the WISC-III measures the same constructs with equal fidelity across time which allows unequivocal interpretation of score differences as reflecting changes in underlying latent…

Applied factor analysis to the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) scores for 505 gifted students, to evaluate the construct validity of the WISC-III with this population. Results are consistent with the hypothesis that subtests that emphasize speed of reading are not valid for gifted children and suggest that an…

Although the Wechsler Intelligence Scale for Children-Revised (WISC-R) is being rapidly replaced by the third edition of the WISC, questions concerning the construct validity of the WISC-R have not yet been resolved, including the number of factors it measures and whether the same constructs fit across all age levels. This study sought to…

The factor structures of the 10 Wechsler Intelligence Scale for Children-III core subtests were studied with 161 black students receiving special education services. Results provide evidence of a large first principal factor as well as the expected verbal and performance factors. Implications for psychologists are discussed. (SLD)

This study evaluated the construct validity of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) with children (ages 8 to 13) having learning disabilities who were either Hispanic (N=120) or Non-Hispanic white (N=120). Factor analyses found that the WISC III has a three factor structure consisting of verbal comprehension,…

Construct validity of the Wechsler Intelligence Scale for Children-Revised using 189 Black, 184 Hispanic, and 187 White 6- to 11-year-olds was investigated. A two-factor solution yielded similar loadings corresponding to verbal comprehension and perceptual organization for all three groups. Three-factor solutions yielded similar loadings for…
