G.E. Smith et al. (1992, 1993) confirmed that 5 factors underlie the covariance structure of a core battery of the WAIS-R, WMS-R, and AVLT administered to the Mayo's Older Americans Normative Studies sample and to an independent clinical sample. In the present study, full factor scores generated by this 5-factor model were used as criterion variables in the development of a short battery. It was determined that 16 of the 24 subtests were sufficient to explain substantial variance in the 5 factor scores. However, 1 additional immediate memory subtest must be administered as a prelude to a delayed recall test. Thus, a collection of 17 subtests are offered as a short battery for older persons. Norms for the calculation of Mayo Cognitive Factor Scales scores are presented.
