title: Wandering and the physical environment.
abstract: BACKGROUND
  Guided by the need-driven dementia-compromised behavior (NDB) model, this study examined influences of the physical environment on wandering behavior.
  
  
  METHODS
  Using a descriptive, cross-sectional design, 122 wanderers from 28 long-term care (LTC) facilities were videotaped 10 to 12 times; data on wandering, light, sound, temperature and humidity levels, location, ambiance, and crowding were obtained. Associations between environmental variables and wandering were evaluated with chi-square and t tests; the model was evaluated using logistic regression.
  
  
  RESULTS
  In all, 80% of wandering occurred in the resident's own room, dayrooms, hallways, or dining rooms. When observed in other residents' rooms, hallways, shower/baths, or off-unit locations, wanderers were likely (60%-92% of observations) to wander. The data were a good fit to the model overall (LR [logistic regression] chi(2) (5) = 50.38, P < .0001) and by wandering type.
  
  
  CONCLUSIONS
  Location, light, sound, proximity of others, and ambiance are associated with wandering and may serve to inform environmental designs and care practices.
