ABSTRACT
Background: Hypertension is a chronic disease that requires long-term medication adherence to prevent cardiovascular complications. However, medication adherence remains suboptimal, particularly among coastal populations facing geographical barriers and limited healthcare access. Self-efficacy has been recognized as an important psychological factor influencing adherence to antihypertensive treatment.
Objective: To examine the relationship between self-efficacy and medication adherence among patients with hypertension living in the coastal area of Wakatobi Regency.
Methods: An analytical observational study with a cross-sectional design was conducted among 100 patients with hypertension selected using proportionate stratified random sampling. Self-efficacy was assessed using the Hypertension Self-Efficacy Scale (HSES), while medication adherence was measured using the Morisky Medication Adherence Scale (MMAS-8). Data were analyzed using descriptive statistics, Chi-square test, Spearman's rank correlation, and ordinal logistic regression with a significance level of p < 0.05.
Results: Most participants demonstrated moderate self-efficacy (46.0%) and moderate medication adherence (43.0%). Spearman's correlation analysis revealed a significant positive correlation between self-efficacy and medication adherence (rho = 0.612; p < 0.001).
Conclusion: Self-efficacy is significantly associated with medication adherence among patients with hypertension living in the coastal area of Wakatobi Regency. Strengthening patients' self-efficacy through educational and family-centered interventions may improve long-term adherence to antihypertensive therapy.
