Correlates of caregiver-rated quality of life in assisted living: The Maryland assisted living study

Abstract

We used a cross-sectional study to examine the correlates of caregiver-rated quality of life (QOL) in 198 randomly selected residents from a stratified random sample of 22 assisted living facilities in central Maryland. We measured QOL by using the Alzheimer's Disease-Related Quality of Life Questionnaire. In general, despite cognitive impairment, residents in assisted living were rated as having a high QOL. In a multivariate regression, we found that nonmood neuropsychiatric symptoms were the strongest correlate of QOL, explaining 37% of the variance. Depressive symptoms, functional dependence, marital status, and cognition also contributed to the model, but only minimally. Because of the strong association of neuropsychiatric symptoms with QOL, special attention should be given to their recognition and amelioration.
