Objective: Subjective executive function (EF) measures may provide valuable information about real-world cognitive and functional difficulties not always apparent on objective EF tests. 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 EF difficulties on 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) with varying degrees of objective and subjective cognitive impairment. The 9 BRIEF-A scales served as DVs while predictors in the multivariate linear regression included objective EF tests, self-report mood inventories, an informant completed instrumental ADL scale, age, sex, and education. Results: Increased Physiological Anxiety was a significant predictor of increased EF difficulties for 7/9 BRIEF-A subscales (p < .05) and increased Worry/Oversensitivity was a significant predictor of increased EF difficulties for 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.
