Age-expanded normative data for the Ruff 2&7 Selective Attention Test: evaluating cognition in older males.
The Ruff 2&7 Selective Attention Test's (RSAT) current scoring data are relatively limited for older adults because persons over the age of 70 years were not included in the normative sample. Prior evidence suggests that changes in attention skills, such as those evaluated by the RSAT, may distinguish normal cognitive aging from pathologic cognitive decline. Thus normative data for older individuals on this measure increase its utility in diagnosing Mild Cognitive Impairment (MCI) and dementia, and enhance its potential use in clinical and research settings. Data from 415 male volunteers (mean age = 69.5 ± 5.7 years) in the PREADViSE clinical trial were used in the current investigation. Analysis of covariance (ANCOVA) shows statistically significant effects of age, race, and education on RSAT Speed measures. Results indicate that age-expanded norms will provide a more accurate reflection of the typical performance of older individuals on the RSAT.
