Mayo cognitive factors scales: Derivation of a short battery and norms for factor scores.

G. E. Smith et al (see PA, Vol 80:4129 and 24183) confirmed that 5 factors underlie the covariance structure of a core battery of the Wechsler Adult Intelligence Scale—Revised (WAIS—R), Wechsler Memory Scale—Revised (WMS—R), and Auditory Verbal Learning Test 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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
