| Annotation | Development of a Quality of Life questionnaire rated by professionals that can be used for people with dementia at different stages of the disease living in residential settings was performed in two phases. First, item generation and pilot testing resulted in 49 items. Second, a field survey to evaluate the psychometric properties was conducted with a sample of 238 people with dementia residing in 10 nursing homes in the Netherlands. The scalability of the sub-scales positive affect, negative affect, restless tense behaviour and social relations is strong; for care relationship, positive self image, feeling at home, and having something to do, scalability was moderate; and for social isolation it was weak. The reliability coefficient Rho (under assumption of double monotonicity) varied from 0.60 for social isolation to 0.90 for positive affect. 21 of the 40 items are suited for people with very severe dementia. The QUALIDEM is an easy to administer and sufficiently reliable rating scale that provides a QOL profile of people with dementia in residential settings. The QUALIDEM can be used for evaluation as well as for research and practice innovation. (RH). |
