Mayo's Older African American Normative Studies: norms for the Mattis Dementia Rating Scale.
Normative data are presented for older African Americans on the Mattis Dementia Rating Scale (DRS). These data were collected as part of Mayo's Older African Americans Normative Studies (MOAANS) in an effort to develop age-appropriate norms for African Americans elders on commonly used measures in neuropsychological assessment. In this study, the DRS was administered to 307 MOAANS participants ranging in age from 56 to 94 years. Age-corrected subtest and total scores were derived based on percentile ranks from actual frequency distributions across seven age ranges. Also presented is a regression-based computational formula that may be applied to the age-corrected DRS total score to further correct for years of education. These norms should help improve interpretation of DRS performance in African Americans and allow for greater diagnostic accuracy in patients with early cognitive decline.
