Smith et al. (1992) confirmed 5 factors to account for the covariance structure of a "core battery" of the Wechsler Adult Intelligence Scale-Revised, Wechsler Memory Scale-Revised, and Auditory Verbal Learning Test administered to the Mayo Older Americans Normative Studies (MOANS) sample. We attempted to replicate this model in a clinical sample. Data from 417 clinical cases were used in LISREL confirmatory factor analyses. Modifications of the original secondary variable assignments were necessary to obtain a 5-factor model with adequate fit. This 5-factor model was superior to alternative models. The results support the use of a 5-factor model in the development of factor-based summary indexes.
