The Well-Being Measure – dementia is a digital observation instrument that assesses the well-being of persons with dementia on four domains of quality of life: Mental well-being, Physical well-being, Participation, and Living arrangements. Its goal is to assess the well-being of persons with dementia in an easy and positive way. Besides illness-related symptoms and problems, the instrument also assesses positive aspects of functioning. It visualizes the results and provides specific behavioural advice to the caregivers. The goal of the present article is to conduct a first psychometric analysis: factor structure, reliability (Cronbach’s alpha), concurrent, and convergent validity. Observations were carried out among 168 persons with dementia in eleven different small-scale psychogeriatric wards. Five existing instruments were used among 63 persons to validate the Well-Being Measure-dementia: quality of life, neuropsychiatric symptoms, care dependency, depression, and agitation. The expected factor structure was found in each of the four domains. Coefficients were high on the expected factor and low on the other factor(s). The scale means were on the positive side, but showed an adequate range and variability. Reliability was satisfactory to good. The relation with existing scales was moderate to strong. The pattern of relations was consistent with the measurement intentions of the different existing instruments. The Well-Being Measure – dementia appears to be a valid and reliable scale. Further studies should assess its test-retest reliability, sensitivity to change and relation with the course of dementia. Current experience shows that the instrument is also useful in everyday practice.
