A confirmatory factor analysis of the Stanford–Binet Intelligence Scales,Fifth Edition,with a high‐achieving sample

The Stanford–Binet Intelligence Scale, Fifth Edition (SB5), is a recently published, multidimensional measure of intelligence based on Cattell–Horn–Carroll (CHC) theory. The author of the test provides results from confirmatory factor analyses in the technical manual supporting the five‐factor structure of the instrument. Other authors have examined this factor structure through EFA using the standardization sample, and have not found evidence of a five‐factor model. The purpose of the current study was to examine the internal construct validity of the SB5 using an independent sample of high‐functioning students. Participants included 201 high‐functioning, third‐grade students ranging in age from 8 years, 4 months to 10 years, 11 months. Five models of the SB5 were analyzed using Analysis of Moment Structures (AMOS). Our findings indicated that a hierarchical, four‐factor, post‐hoc model provided the best fit to the data. Generally, implications for school psychologists include a better understanding of the factor structure of the SB5, especially as it relates to high‐achieving children. Directions for future research are also discussed. © 2010 Wiley Periodicals, Inc.
