The Relationship between Subjective Memory and Objective Cognition, Depression, and Anxiety by Dementia Status

This secondary data analysis of the Health and Retirement Study – Aging, Demographics, and Memory Study (ADAMS) examines the relationship between subjective cognition and objective performance, depression, and anxiety in cognitive impairment with no dementia (CIND) and dementia. With a cross-sectional design, this study consists of 480 older adults between ages 72105. Participants completed the Mini-Mental State Examination. The Wechsler Memory ScaleRevised Logical Memory I/II measured memory. Anxiety and depression were measured by the Neuropsychiatric Inventory. Subjective memory was measured by the HRS Self-report Memory and Informant Questionnaire on Cognitive Decline in the Elderly. Independent t-tests and Pearson correlation analysis were employed to determine differences between the dementia and non-dementia groups. Results demonstrated that the CIND group had significantly better general cognition; more severe cognitive/memory problems in the dementia group showed weaker relationships between general cognition and memory performance; anxiety/depression were weakly related in CIND and moderately related in dementia.
