[Factors related to discrepancy in evaluation on functional capacity between reports by community-dwelling older people with cognitive decline and their family members].
Overestimation or underestimation of functional capacity in community-dwelling older people with cognitive impairment was evaluated between the responses of subjects and family members (proxies) by cognitive function level. Out of all the residents aged 65 years and over living in Yoita town, Niigata Prefecture in 2000 (n = 1,673), 1,544 voluntarily participated in the interview survey held at community halls or at home (92.3% response). They underwent the Mini-Mental State Examination (MMSE) for assessment of cognitive function and answered questionnaires comprising socio-demographic, psychological, physical and medical, and social activity items (2000/11). ⋯ SCD subjects significantly overestimated total and Instrumental Self-Maintenance scores in TMIG-IC more than control or SCD subjects. Multiple logistic regression analyses indicated that complaints of memory by the proxy, response by spouse, and higher levels of education were extracted as significantly independent variables affecting overestimation for functional capacity. On the other hand, aging affected underestimation.
