Multi-Sensory Stimulation in 24-hour Dementia Care - Nivel

mean pre-test post-test differences in the experimental group were tested against the
mean pre-test post-test differences in the control group. Relevant covariates were
selected for adjusted analysis to correct for differences in the residents’ conditions
and background characteristics of residents or CNAs.
Figure 1.3 shows the most important elements of the intervention and the
measurements.
The post-test was planned 18 months after the pre-test, because 15 months was
considered to be the minimum time needed for successful implementation of the new
care model (Finnema, 2000). This time was required to effect a change from taskoriented
care to resident-oriented care and to effect changes at organizational level.
At the caregivers’ level, the implementation of snoezelen in 24-h care required
several interventions to improve knowledge, skills and habits. Interventions at the
organisational level were needed to guarantee persistent care changes. These
concerned, for instance, adaptations of procedures and activities (e.g., breakfast
project with nice-smelling food), investments in snoezel materials or adaptations in
the daily schedule (e.g., no longer waking up of residents who prefer to sleep late, no
force to be ready with the morning care before the coffee break).
The data collection to evaluate the implementation process of snoezelen on the
experimental wards was carried out using a questionnaire about the training,
interviews about the implementation and attendance to the follow-up meetings, also
regarding implementation.
