Preliminary investigation of two functional assessment methods for people with dementia: Effectiveness and acceptability

Many functional assessment procedures have been developed and validated for use with people with intellectual and developmental disabilities. However, there is a paucity of research exploring the utility and social acceptability of functional assessment methods for people with dementia. We conducted direct observations in the natural environment to produce data for conditional probability analyses
and an experimental functional analysis of the behavior of two women with dementia. We found that the conditional probability analysis yielded similar conclusions about function as the data from the experimental functional
analysis for both participants. Importantly, staff rated the direct observations as more socially acceptable. We also report barriers to conducting both methods in older adult settings that warrant further exploration, including the use of the assessments with people with dementia and intact vocal verbal repertoires.
