Input: Two new trials were included in this update. Baker 2003 was an expanded study of Baker 2001 reported in the previous version. Both Baker 2003 and van Weert 2005 examined the short-term and longer-term effects of snoezelen on behaviour, mood, and communication of people with moderate to severe dementia. The format of implementation was different in the two trials: one was session-based snoezelen programme (Baker 2003), whilst the other was a 24-hour integrated snoezelen care (van Weert 2005). Owing to the differences in study methodology, the results of the two trials were not pooled for analysis. The session-based snoezelen programme (Baker 2003) did not show any effects on behaviour, mood, cognition and communication / interaction in the short term (during or immediately after sessions) or longer term (at post-intervention or 1-month post-intervention follow-up). Likewise, the 24-hour integrated snoezelen care (van Weert 2005) failed to demonstrate any significant short-term and longer term effects on behaviour, mood and interaction. A more vigorous review methodology was adopted in this update. The study of Kragt 1997, reported in the previous version, was excluded because the snoezelen programme only consisted of three sessions, which was considered too brief for a therapeutic intervention. Two new trials were reviewed. Meta-analyses could not be performed because of the limited number of trials and different study methods of the available trials. Overall, there is no evidence showing the efficacy of snoezelen for dementia. There is a need for more reliable and sound research-based evidence to inform and justify the use of snoezelen in dementia care.
Output:

Originally, two randomised clinical trials were available for this review. Some short-term benefits were documented in promoting adaptive behaviours in people with dementia during and immediately after their participation in the sessions. In this update, two new trials were included and revealed two different forms of applying snoezelen to dementia care. One is a session-based snoezelen programme while the other is a 24-hour integrated snoezelen care programme. Both trials did not show any significant effects on behaviour, interaction, and mood of people with dementia.
