Mayo's Older Americans Normative Studies (MOANS): Factor Structure of a Core Battery

Confirmatory factor analyses were completed separately with the WAIS-R and the WMS-R. Confirmatory factor analyses were also performed on a "core battery" composed of the WAIS-R, WMS-R, and the Rey Auditory-Verbal Learning Test (AVLT) when administered together. Participants were from the...

Description
Summary:Confirmatory factor analyses were completed separately with the WAIS-R and the WMS-R. Confirmatory factor analyses were also performed on a "core battery" composed of the WAIS-R, WMS-R, and the Rey Auditory-Verbal Learning Test (AVLT) when administered together. Participants were from the Mayo Older Americans Normative Studies (MOANS), which include 526 healthy, community-dwelling people ages 55-97 years. LISREL analysis of the WAIS-R found a 3-factor model to be acceptable, supporting extension of the Verbal Comprehension (VC), Perceptual Organization (PO), and Freedom from Distractibility (FFD) model of the WAIS-R to "normal" people ages 55-97 years. A 2-factor model of the WMS-R involving attention and general memory was supported. A 5-factor model of our core battery was supported and included VC, PO, Attention, Learning, and Retention. The Retention factor included Logical Memory, Visual Reproduction, and AVLT percent retention scores.
