Association of perceived health and depression with older adults' subjective memory complaints: contrasting a specific questionnaire with general complaints questions.

The objectives of this paper were to evaluate the association of subjective memory complaints (SMC) with perceived state of health, mood and episodic memory (associative and everyday memory). We studied these areas using two different complaint assessment methods (three general questions and a validated scale). The study included 269 older adults (aged 65-87) with age-related memory changes, but without cognitive impairment. They were evaluated with Mini-cognitive Exam, Rivermead Behavioural Memory Test (a test of everyday memory), Paired Associates Learning Test, Memory Failures of Everyday Questionnaire, three memory complaints questions, Nottingham Health Profile and Geriatric Depression Scale. The results indicated that memory for everyday performance, mood and perceived health were independent predictors of SMC, with mood and perceived health being stronger predictors than actual memory performance. Age was not associated with subjective memory and, with regard to level of education, only the illiterate level was associated with SMC. A specific questionnaire on subjective memory was found to be preferable to an aggregate of complaints questions on self-reported memory; only health profile was found to predict the outcomes on memory complaints questions. Our conclusion is that a group of underlying factors other than everyday memory were playing a role in SMC; these SMC of subjects with age-related memory changes were mainly associated with subjective evaluations of their health.
