The therapeutic environment screening scale

Abstract
As part of a study of care for patients with Alzheimer's disease and related disorders in 31 dementia units, (special care units) and 32 traditional units in five states, an observational screening checklist was designed and field tested. That checklist the Therapeutic Environment Screening Scale (TESS) uses 12 items to evaluate the appropriateness of a nursing home unit for residents with dementing disorders. The therapeutic principles evaluated by the instrument are: eliminating potentially noxious stimuli, enhancing mood and self image, promoting safety, accommodating a range of private and social activities, and providing access to the outdoors. Application of the instrument showed that the 63 settings studied did differ in the 12 environmental characteristics studied, and that as a whole, dementia units scored significantly better than traditional nursing home units.
