Background: The aim was to assess the impact of a one-to-one 30-min individualized interaction per day on the behavior and quality of life of care-dependent residents with dementia. Methods: In a pre-/post-test study, 15 care-dependent residents with dementia (mean age 88.8 years, 86.7% women) were included. Resident behavior was measured using video observation and quality of life using Qualidem. Health care professionals (n = 13) and direct relatives (n = 4) were interviewed about the effect of the intervention. The effect of the intervention was analyzed using the Friedman analysis of variance. Results: The video observation showed that maintaining eye contact, touching, responding to speaking, tracking observable stimuli and asking questions about the activity significantly increased during the intervention. These findings were supported by interviews with nurses who described experiences of making human-to-human contact with the residents. No significant overall changes were found in quality of life. These findings were partially supported by interviews with health care professionals and relatives as some perceived effects beyond the 30-min intervention. Conclusions: Interaction offered on a one-to-one basis tailored to individual preferences significantly improved positive interactive behavior of care-dependent residents with dementia during the intervention. Surveys revealed no significant overall effect of the intervention. The interviews indicated there might be effects beyond the intervention for some residents.
