en Aim: Hypertension is a chronic and asymptomatic disease leading to death of at least 45% of patients with cardiovascular diseases (CVDs). Self-care is important to minimize the risks and complications caused by hypertension.<br />This aim of the present study was to determine the predictive power of constructs of the Health Belief Model (HBM) in self-care behaviors of patients with hypertension.<br />Methods: This was a descriptive-analytic study of cross-sectional type carried out on 125 patients over 30 years old with hypertension who referred to the rural health centers in Rasht city. Sampling was done in multi-stage form, and the patients were selected randomly. To collect data, a valid and reliable questionnaire containing demographic information and questions of constructs of the HBM and self-care behaviors was used.<br />Findings: Based on Pearson’s correlation analysis, a significant and negative relationship was observed between self-care behaviors and construct of perceived barriers. Also there was a significant and positive relationship between self-care behaviors and the construct of cues to action. Based on linear regression analysis, the HBM could predict 19% of variance of self-care behaviors by two constructs of perceived barriers (B=0.22, SE=0.04, P=0.01) and cues to action (B=0.19, SE=0.06, P=0.02).<br />Conclusion: According to the predictive power of the HBM and the role of constructs of perceived barriers and cues to action in self-care behaviors of patients with hypertension, it is needed to focus on educational interventions based on this model to reduce the perceived barriers and influencing the cues to action.
