Comparison of Dementia-Specific Quality of Life Measures in Adult Day Centers

Abstract

This study evaluated five dementia-specific quality of life (DQOL) measures including client interviews, staff proxies, and observations with 54 clients in three adult day centers. Also, the relationship of cognitive and functional status to each of the DQOL measures was assessed. Client interviews correlated well with each other, but not with other measures. Staff proxies were strongly correlated with each other and moderately correlated with the observational measure. On average, clients rated their DQOL higher than staff. Analyses suggest that functional impairment is associated with poorer DQOL as indicated by staff and observer measures. Possible explanations and implications are explored.
