This study sought to understand why nursing home (NH) residents’ (n = 39) preferences may change at different points in time. Using secondary data analysis of cognitive interviews, the study identified 4 major domains or reasons for a change: within person (i.e., health), facility environment (i.e., schedule), social environment (i.e., relationships), and global environment (i.e., weather). The study highlights the contextual factors that influence a person’s preferences and ratings of importance that must be considered to keep care plans and delivery matched to the individual’s preferences.
