[Effects of social support on well-being of demented nursing home residents. The Käferberg Visitation Study].

Abstract

BACKGROUND: Relatives and caregivers of patients with dementia are often insecure about the impact of their efforts. This study examines whether and to what extent social support in the form of regular visits is increasing the well-being of demented aged. PROCEDURE: A field experiment with slightly to seriously demented institutionalized aged persons (MMS 5-25) was carried out to assess the effect of increased social support upon their well-being. Voluntary helpers, who were willing to visit their patients on a regular basis, were recruited by appeals at the senior university and by advertisements. The volunteers were trained to deal with the demented and were looked after regularly. The test subjects were randomly assigned to one of two test groups. The first group was visited regularly for ten weeks, whereas the second group served as a control group. The participants of the experimental group received a visiting card with a photo of the volunteer and the next appointment date to remember their visitors and to increase the effect of predictability. RESULTS: The effect of visits on the well-being of the institutionalized aged persons was significantly positive (F(1,39) = 11.16, p < 0.002). The psychological, physiological and social well-being of the participants was improved. Additionally, visits moderated the pain resulting from physical illness and seemed to decrease the effects of mental decline on their performance. Furthermore, it was most impressive to find that the demented aged really took notice of the visits and seemed to remember them in one way or an other. The study pointed out that demented aged persons are still very sensitive in an emotional respect and that they are still able to give astonishing good and differentiated information about their feelings even in an advanced state of dementia. Even the volunteers gained from their visits, which was shown by their higher well-being after their visits.
