Popis: OBJECTIVES—Examine the performance MCI and non-MCI participants on an objective measure of everyday or real-world memory and subjective items assessing competency within the same instrumental domains. In addition, determine whether ECB can uniquely predict MCI status. DESIGN—Cross-sectional SETTING—Independently-living sample of urban dwelling elders in Baltimore MD. PARTICIPANTS—The sample consisted of 555 ranging in age from 50 to 95 years (M = 68.75, SD = 9.61) MEASUREMENTS—Objective performance in three instrumental domains (i.e., medication use, financial management, nutrition/food preparation) was assessed by the Everyday Cognition Battery ECB Memory Test. Subjective performance with in the same instrumental domains was also assessed. RESULTS—No difference was found between MCI and Non-MCI elders on the subjective items of IADL competency. A significant multivariate effect for cognitive status group [F(3, 507) = 21.88, p < .05, 2 =.12] was observed for the objective measure, with MCI participants performing, on average, significantly worse than Non-MCI participants on all thee instrumental domain subscales. The medicine use (OR = .96, 95% CI = .94–.99) and financial management (OR = .93, 95% CI = .91–.96) subscales of the ECB Memory Test were both unique and significant predictors of MCI. CONCLUSION—This study adds to the growing body of literature suggesting that cognitively complex instrumental activities of daily living might be compromised in elders with MCI. Moreover, the ECB Memory Test might be a clinically useful tool in evaluating real-world competency.
