N2  - Background: The current study sought to develop a valid, reliable and
unobtrusive tablet computer-based observational measure to assess
engagement of people with advanced dementia. The Video Analysis
Scale of Engagement (VASE) was designed to enable the rating of
moment-by-moment changes in engagement during an activity, which
would be useful for both future research and current residential care.
Methods: An initial version of the VASE was tested. Face validity and
content validity were assessed to validate an operational definition of
engagement and develop an acceptable protocol for the scale. Thirtyseven
non-professional and professional volunteers were recruited to
view and rate level of engagement in music activities using the VASE.
Results: An inter-class coefficient (ICC) test gave a high level of rating
agreement across professionals and non-professionals. However, the
ICC results of within-professionals were mixed. Linear mixed
modelling suggested that the types of interventions (active or passive
music listening), the particular intervention session being rated, time
period of video and the age of raters could affect the ratings.
Conclusions: Results suggested that raters used the VASE in a
dynamic fashion and that the measure was able to distinguish
between interventions. Further investigation and adjustments are
warranted for this to be considered a valid and reliable scale in the
measurement of engagement of people with advanced dementia in a
residential care setting.
