In the present study, the relationship between self-reports and objective measures of health status and measures of cognitive performance was examined. Participants consisted of 437 persons ( M =72.91 years) from the Charlotte County Healthy Aging Study, a population-based sample of older adults. Cognitive performance was assessed by tests of episodic memory, perceptual speed, and attention. Health status was indexed by subjective ratings, self-reports, and objective measures. The health measures accounted for significant variance on both the Trailmaking A and B tests, accounting for a modest amount of variance (4.4% and 1.1%, respectively). The health measures were not significantly associated with performance on the measures of attention or episodic memory. The results suggest that health status is associated with processing speed to a greater degree than higher order cognitive processes.
