Background: Hypertension is a chronic disease that requires long-term management through effective self-care behavior. Family support plays a crucial role in encouraging adherence and success in disease management among hypertensive patients. Method: This study used a quantitative approach with a cross-sectional design. A total of 106 respondents were selected using a consecutive sampling technique. Data were collected using validated and reliable questionnaires and analyzed using the Somers’ D test to determine the relationship between family roles and self-care management. Result: The majority of respondents received good family support (76.4%) and demonstrated good self-care management (61.3%). Statistical analysis showed a significant relationship between family roles and self-care management (p < 0.001), with a Somers’ D coefficient of 0.430. Family roles explained approximately 24.6% of the variation in patients' self-care behavior. Conclusion : There is a significant relationship between family roles and self-care management among hypertensive patients. Good family support, particularly emotional and instrumental support, can enhance the effectiveness of self-care in managing hypertension.
