| Summary: | Abstract Background Given the rapid aging of the population in Korea, efforts to slow down or prevent frailty, to support the health of older adults, should be an important public health priority. This may allow them to continue living within the community by keeping their functional independence for as long as possible. This study aimed to evaluate the nurse-led multicomponent intervention for community-dwelling pre-frail or frail elderly on physical and psychosocial outcomes. Method A non-equivalent control pre-, post-, and follow-up test design was used with a sample of 126 prefrail or frail older adults (62 in the experimental and 64 in the control group). The 12-week multicomponent intervention for the experimental group comprised physical exercise, cognitive training, and nutrition and disease management education. Outcome variables (Timed Up and Go Test results and measures of frailty, handgrip strength, depression, social activity, and social support) were measured both pre- and post-intervention, and after the 12-week follow-up period. Results For each group, we assessed the significant interaction of time with frailty, depression, social activity, and social support, as well as Timed Up and Go Test results. In the experimental group, levels of depression decreased while levels of social support and social activity increased from each measurement period to the next, within the 12-month study period; those in the control group were relatively stable over time. Conclusions The results indicate that nurse-led multicomponent intervention was effective for improving physical and psychosocial function of the (pre)frail older adults living alone in Korea, suggesting that older adults can take proactive roles in conducting their daily life and managing their health. A strategy for disseminating widely sustainable nurse-led multicomponent interventions should be developed for community-dwelling frail elderly who live alone.
