A cRCT was performed in 30 Dutch long-term care homes between 2011-2014, involving 89 dual sensory impaired older adults and 56 licensed practical nurses. The long=term care homes were randomly assigned into intervention clusters (n=17) and control clusters (n=13). The older adults of the intervention cluster received a nurse-supported self-management program spread over a period of 5 months, the older adults of the control group received usual care. Effectiveness was evaluated by the primary outcome social participation. Secondary outcomes were autonomy, control, mood and quality of life. The self-management program was successful in empowering the dual sensory impaired older adults to address instrumental daily living problems, but failed to address other domains of social participation. Process evaluation revealed key barriers to their engaging in social interaction. The dataset presents (1) the statistical data on the primary and secondary outcomes, measuring the effectiveness of the program, and (2) the qualitative data collected from the intervention diaries of the nurses, reflecting the problems and wishes identified by the dual sensory impaired older adults.
