Abstract

The interpretation of the French Wechsler Intelligence Scale for Children-Fifth Edition (WISC-V) is based on a 5-factor model with Verbal Comprehension (VC), Visual Spatial (VS), Fluid Reasoning (FR), Working Memory (WM), and Processing Speed (PS). Evidence of the factorial structure of the French WISC-V was established only through Confirmatory Factor Analyses (CFAs). However, as suggested by several authors, factorial structure should derive from both Exploratory Factor Analysis (EFAs) and CFAs. The first goal of this study was to examine the factorial structure of the French WISC-V with EFAs for five age groups: 6-7, 8-9, 10-11, 12-13, and 14-16 years. For age groups, the WISC-V inter-correlation matrix for the 15 subtests scores was used. Factor extraction criteria (MPA, HPA, BIC, SABIC, etc.) suggested that 1 factor should be retained for age groups 8-9 and 10-11, 2 factors for age group 12-13, and 3 factors for age groups 6-7 and 14-16. None criteria supported a five first-order factors model for these five age groups. To disentangle the contribution of 1st and 2nd order factors, the Schmid and Leiman orthogonalization transformation (SLT) was applied. Overall, no evidence for 5 factors was found. For each group, results indicated that the g-factor accounted for the most important part of the common variance. We also addressed this issue by testing bifactor models. Results indicated that bifactor models fitted better the data than higher-order models. Our finding suggested that for each age group, users do not discount the FSIQ when interpreting the WISC-V.
