Four nurse researchers independently reviewed de-identified video segments of three patients living with dementia. Each reviewer watched the segments twice, and each time they documented the behaviours observed during one-minute intervals using numerical ratings from the Dementia Observation System (DOS). Test-retest and inter-rater reliability were assessed to establish the utility of the DOS for comparison with the multi-sensor predictive system.
Results indicated that the DOS has substantial test-retest reliability and moderate inter-rater reliability. Both types of reliability were higher for ratings of behaviour type and intensity than ratings associated with contextual variables. A system that predicts responsive behaviours will help caregivers develop a plan of care for people living with dementia, which may reduce the burden of caregivers.
