title: Snoezelen: an overview of research with people with developmental disabilities and dementia.
abstract: OBJECTIVE
  This paper was to provide an overview of the research studies on snoezelen with people with developmental disabilities and dementia.
  
  
  METHODS
  Computerized and manual searches were carried out to identify the aforementioned studies. Within-session, post-session, and longer-term effects of snoezelen were examined.
  
  
  CONCLUSIONS
  Twenty-one research studies were identified, 14 concerning people with developmental disabilities and seven people with dementia. Of those studies: 14 reported positive within-session effects; four positive post-session effects; and two positive longer-term effects. These findings were discussed in relation to: (1) methodological aspects (weaknesses) of the studies; (2) the cost of arranging a snoezelen programme and possibilities of reducing the range of stimuli available in the programme; and (3) some research issues for advancing the understanding and effectiveness of intervention programmes with people with developmental disabilities and dementia.
