Objective: Subjective measures of executive function (EF) may provide valuable information about real-world cognitive and functional difficulties not always apparent on objective tests of EF. Previous research reports modest associations between subjective and objective EF tests, raising questions about the validity of both types of measurement approaches. Moreover, there is little research on the relationship between subjective report of EF and other relevant variables such as mood or activities of daily living in older adults. The current study investigated various predictors of self-reported difficulties with EF on 9 subscales of the Behavior Rating Inventory of Executive Function—Adult version (BRIEF-A). Method: Participants were 211 non-demented, community-dwelling older adults (aged 70 and older) from the Einstein Aging Study with varying degrees of objective and subjective cognitive impairment. The 9 BRIEF-A subscales were modeled as outcomes in multivariate linear regression analyses using objective EF tests, self-report mood inventories, an informant completed instrumental ADL scale, as well as age, sex, and education. Results: Physiological Anxiety was a significant predictor of increased EF difficulties on 7/9 BRIEF-A subscales (p < .05) and increased Worry/Oversensitivity was a significant predictor of increased EF difficulties on 4/9 BRIEF-A scales (p < .05). The Test of Practical Judgment was the only objective test to associate with multiple BRIEF-A scales (5/9), with poorer scores predicting increased EF difficulties (p < .05). Conclusion: These findings highlight the important influence of older adults' emotional states on subjective ratings of cognition and suggest that the BRIEF-A taps into aspects of EF related primarily to judgment and decision-making. Findings are discussed in relation to the use of the BRIEF-A with diverse elderly populations.
