Abstract

Purpose: We conducted this study to determine whether neuropsychiatrie symptoms and environmental characteristics are associated with quality of life in assisted living residents with dementia. Design and Methods: We used a cross-sectional study of 134 residents from 22 facilities and employed the Alzheimer's Disease-Related Quality of Life Scale and the Neuropsychiatric Inventory. A scale was developed to capture the homelike climate of each facility. Linear regression analyses were used to estimate the relationship of neuropsychiatric symptoms and homelike climate with quality of life, controlling for sociodemographics, cognition, functional dependence, and physical health. Exploratory analyses and graphical techniques were employed to test for environmental-level moderating effects. Results: Agitation, depression, apathy, and irritability were significant predictors of quality of life, explaining 29% of the variance. Neither facility size nor homelike environment was significantly associated with quality of life in univariate analyses. Size of facility moderated the relationship between agitation and quality of life. Implications: Neuropsychiatrie symptoms impair quality of life in residents with dementia. Further research should investigate the role of other environmental aspects.
