The research was carried out as a pre-test, post-test patterned intervention with one group in order to evaluate the psychoeducation given to older people at nursing homes for a healthy lifestyle and developing life satisfaction. The research was done with 21 female and 21 male older people staying at the state-owned Seyran Bağlari Nursing Home/Elderly Caring Rehabilitation Center and the Ümitköy Nursing Home. In the psychoeducation program, each session was conducted for a duration of 60-90 min in the nursing homes' education classrooms. After the psychoeducation program, the life satisfaction index, the health promotion lifestyle profile total, and the subscale (nutrition, health responsibility, self realization, stress management, interpersonal support, and exercise) mean scores, significantly increased statistically. It is suggested that the nursing homes' health workers, and especially nurses who work full-time, should promote such psychoeducation.
