OBJECTIVES: To examine the performance subjects with and without mild cognitive impairment (MCI) on an objective measure of everyday or real-world memory and subjective items assessing competency within the same instrumental domains; to determine whether the Everyday Cognition Battery (ECB) can uniquely predict MCI status. DESIGN: Cross-sectional. SETTING: Independent-living sample of urban dwelling elders in Baltimore Maryland. PARTICIPANTS: The sample consisted of 555 subjects ranging in age from 50 to 95 (mean 68.8 ± 9.6). MEASUREMENTS: Objective performance in three instrumental domains (medication use, financial management, nutrition and food preparation) was assessed using the ECB Memory Test. Subjective performance within the same instrumental domains was also assessed. RESULTS: No difference was found between elderly subjects with and without MCI on the subjective items of instrumental activity of daily living (IADL) competency. A significant multivariate effect for cognitive status group (F3, 507=21.88, P<.05, η2=.12) was observed for the objective measure, with participants with MCI performing, on average, significantly worse than those without on all thee instrumental domain subscales. The medicine use (odds ratio (OR)=0.96, 95% confidence interval (CI)=0.94-0.99) and financial management (OR=0.93, 95% CI=0.91-0.96) subscales of the ECB Memory Test were unique and significant predictors of MCI. CONCLUSION: This study adds to the growing body of literature suggesting that cognitively complex IADLs might be compromised in elderly people with MCI. Moreover, the ECB Memory Test might be a clinically useful tool in evaluating real-world competency.
