Understanding Discrepancies and Predictors of Self- versus Proxy-Rated Quality of Life in Chinese Community-Dwelling Older Adults with Mild Dementia: A Cross-Sectional Study
Cross-sectional study analyzes quality of life evaluations among older adults with mild dementia, suggesting integration of assessment perspectives.
Key Points
This study examines discrepancies and predictors between self-rated and proxy-rated quality of life in older adults with mild dementia.
Cross-sectional design involving 129 community-dwelling persons with mild dementia and their primary caregivers.
Used multiple assessments including the QoL-Alzheimer's Disease scale and tools for depression, daily activities, and neuropsychiatric symptoms.
Analyzed discrepancies and agreement through statistical methods including Wilcoxon tests and multiple linear regression.
Patients self-rated their quality of life higher than caregivers' ratings with poor-to-fair agreement (ICC = 0.11–0.50).
Independent predictors of poorer self-rated quality of life included higher depressive symptoms (β = −0.354, p = 0.001) and lower elation (β = 0.214, p = 0.013).
Proxy-rated quality of life was poorer with greater neuropsychiatric symptom severity (β = −0.283, p < 0.001) and functional dependency (β = −0.230, p = 0.006).
