Objectives The current study examined within-person associations of self-reports of impaired current memory functioning and perceived decline with depressive symptoms in older adults without cognitive impairment, and whether these associations were moderated by individuals’ levels of neuroticism, conscientiousness, and extraversion. Methods Samples were drawn from the Einstein Aging Study, Rush Memory and Aging Project (MAP), Minority Aging Research Study (MARS), Health and Retirement Study (HRS), and National Health and Aging Trends Study (NHATS), with over 8,000 participants (65+ years) included across data sets. In a series of coordinated analyses, multilevel linear models tested within-person relationships over periods of up to 22 years. Results Across HRS and NHATS samples, self-reports of impaired current memory functioning covaried with depressive symptoms over time. This association was moderated by neuroticism, such that the association was stronger for individuals with higher levels of neuroticism. Across all samples, perceived memory decline covaried with depressive symptoms over time. This association was moderated by neuroticism in MAP/MARS, HRS, and NHATS, such that the association was stronger for individuals with higher levels of neuroticism. Discussion Self-reports of impaired current memory functioning and perceived memory decline are important determinants of older adults’ psychological well-being. In our results, at times when older adults perceive poorer memory functioning or decline, they also tend to report more depressive symptoms. Further, results from two larger data sets suggest that individuals’ level of neuroticism may determine the extent to which self-reports of memory impairment and depressive symptoms covary over time.
