Background: Hypertension is a health challenge that continues to increase in Indonesia due to unhealthy lifestyles and lack of public knowledge. Low health literacy and self-efficacy lead to poor patient self-management. Purpose: To improve patients' understanding and ability to manage hypertension independently Method: A quantitative multimethod: survey correlational analysis and regression. This research was completed in Sukabumi City, West Java Province, Indonesia. In this study, Cochran's sampling design was used to determine the appropriate sample size from a limited population of 473 individuals, purposive sampling was used to determine the sample size so that 213 respondents were obtained. Results: Regression analysis reveals that knowledge of hypertension and self-efficacy significantly predict self-care management (R² = 0.564, adjusted R² = 0.422, p < 0.001). Self-efficacy is the stronger predictor, with minimal multicollinearity (VIF < 2). The absence of autocorrelation and moderate predictive accuracy (RMSE = 0.544) validate the model's robustness. Conclusion: By focusing on the dynamic interplay between these factors, health education programs can be more effective in promoting equitable and sustainable self-care practices among diverse populations.
