The challenge posed by aging, particularly in enhancing psychosocial health in nursing homes has to be addressed. Hence, we evaluated the nurse-led psychosocial interventions to improve social well-being and reduce residents' loneliness. Fifty participants from Chennai engaged in a mixed-methods design, where pre- and post-tests measured social well-being and loneliness. Over four weeks, structured social activities and emotional support interventions resulted in significant improvements in social well-being and notable reductions in loneliness. The study's findings demonstrate that nurse-led psychosocial interventions can effectively enhance well-being and minimise loneliness in elderly care settings, supporting the need for targeted strategies in elderly care.
