An Exploratory Investigation of the Factor Structure of the Reynolds Intellectual Assessment Scales (RIAS)

Journal of Psychoeducational Assessment, v27 n6 p494-507 2009
This study investigated the factor structure of the Reynolds Intellectual Assessment Scales (RIAS) using rigorous exploratory factor analytic and factor extraction procedures. The results of this study indicate that the RIAS is a single factor test. Despite these results, higher order factor analysis using the Schmid-Leiman procedure indicates that all subtests are aligned with their theoretically consistent factors. All analyses in this study, including the minimum average partial test, parallel analysis, the Schmid-Leiman procedure, as well as principal factors with orthogonal and oblique rotation, support interpretation at the composite intelligence index level and suggest caution when moving to interpretation at the verbal and nonverbal index levels. The memory subtests should continue to be separated from the main IQ battery because of poor g-loadings and contribution to cross loadings of the intelligence subtests. Interpretation at the subtest level should be eschewed. (Contains 4 tables.)
