Abstract
This study aimed to investigate the effects of Person-Environment Fit on trajectories of cognitive function. Data came from the Health Retirement Study (1998-2010), focusing on those aged 65 and above who had at least one limitation in activities of daily living. Using longitudinal mixed-effect modeling, we analyzed the effects of living in supportive home environments on trajectories of cognitive function over time. Disabled older individuals living alone were likely to experience a decline in cognitive function over time. However, the detrimental effects of living alone were moderated when the home was equipped with supportive features and accessibility. The findings reveal the importance of home modifications for socially and physically vulnerable elders.
