The relationship of family support and self efficacy with diet compliance in patients with coronary heart disease

Coronary heart disease (CHD) is a chronic disease that cannot be cured. One of the problems in the management of CHD is patient adherence to the diet. Family support and self-efficacy can be factors that influence adherence to the diet of CHD patients. The study aimed to determine the relationship between family support and self-efficacy with adherence to the diet of CHD patients. The study used a correlational method with a cross-sectional design. The population was 105 CHD patients taken by purposive sampling technique. Variables are family support, self-efficacy, and diet compliance of CHD patients. The instrument used was a questionnaire. Data were analyzed using the Spearman Rho test with a level of significance≤0.05. There was a significant relationship between family support and diet adherence of CHD patients (p = 0,000) with a positive direction such as the better the family support, the higher the level of diet adherence. The relationship between self-efficacy and diet adherence has a weak relationship (p = 0.025) with a positive direction, the better self-efficacy, the higher the diet adherence. The behavior of adherence to the diet of CHD patients can be improved by improving family self-efficacy support.
