Older adults in social institutions face various psychosocial challenges that may affect their mental condition, therefore appropriate mental health management is needed.

Data were collected through in-depth interviews, observation, and documentation. Data were analyzed using thematic analysis, and data validity was ensured through source and technique triangulation. The results showed that mental health management among older adults was carried out through adaptation to the institutional environment, participation in social activities, and acceptance of their conditions. Social support from caregivers and fellow residents played an important role in helping older adults manage emotions, reduce feelings of loneliness, and enhance a sense of safety and comfort. Social support serves as a fundamental basis for mental health promotion efforts among older adults in social care institutions.
