   BACKGROUND: Depression is among the most important barriers to proper treatment of cardiac patients. It causes failure in accepting their conditions, decreases their motivation in following the therapeutic recommendations, and thus negatively affects their functionality and quality of life. The present study aimed to investigate the effects of an educational program based on Predisposing, Reinforcing, Enabling Constructs in Educational Diagnosis and Evaluation (PRECEDE) model on depression level in coronary artery bypass grafting (CABG) surgery patients.    METHODS: This was a quasi-experimental study in which 54 post-bypass surgery patients of Isfahan Cardiovascular Research Center were investigated. The patients were randomly divided into two groups of intervention and control. The data was collected using two questionnaires. Primarily, the cardiac depression scale was used to measure the degree of depression followed by PRECEDE model-based educational questionnaire to identify the role of the educational intervention on patients. The PRECEDE model-based intervention composed of 9 educational sessions per week (60-90 minutes each). The patients were followed up for two months post-intervention.    RESULTS: Following the educational intervention, mean scores of predisposing, enabling, and reinforcing factors, and self-helping behaviors significantly increased in the intervention group compared to the control group (P < 0.001). In addition, a significant difference in mean scores of depression was observed between the two groups following the educational intervention (P < 0.001).    CONCLUSION: The findings of the current study confirmed the practicability and effectiveness of the PRECEDE model-based educational programs on preventing or decreasing depression levels in CABG patients.         Keywords: Educational Program, PRECEDE Model, Depression, Coronary Artery Bypass Surgery.
