Objective: Whether subjective cognitive complaints are suggestive of depression or concurrent cognitive impairment in older adults without dementia remains unclear. The current study examined this question in a large (N = 1000), randomly selected, community-based sample of adults aged 51 to 99 years without a formal diagnosis of dementia (Successful AGing Evaluation [SAGE] study). Methods: The modified Telephone Interview for Cognitive Status (TICS-m) measured objective cognitive function, the Cognitive Failures Questionnaire (CFQ) measured subjective cognitive complaints, and the 9-item Patient Health Questionnaire (PHQ-9) measured depression. Spearman rho correlations and linear regression models were conducted to examine the relationship among variables in the baseline SAGE sample. Results: There was a weak association between TICS-m and CFQ scores (rho = -.12); however, a moderate to large association was observed for CFQ and PHQ-9 (rho = .44). Scores on the CFQ were not associated with TICS-m scores (beta = -.03, P = .42) after controlling for PHQ-9 and variables of interest, such as age, gender, ethnicity, and physical functioning, while PHQ-9 was significantly associated with CFQ scores (beta = .46, P < .001) after controlling for variables of interest. Conclusions: Subjective cognitive complaints are more likely related to symptoms of depression rather than concurrent cognitive impairment in a large cross-section of community-dwelling adults without a formal diagnosis of dementia.
