The effect of PRECEDE Model-based educational program on depression level in patients with coronary artery bypass grafting

Abstract Background: Depression is among the most important barriers to proper treatment of cardiac patients causing failure in accepting their conditions, decreasing their motivation in following the therapeutic recommendations and thus negatively affects the patients’ function and their quality of life. Objective: To investigate the effect of PRECEDE Model-based educational program on depression level in coronary artery bypass grafting surgery (CABGS) 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 marked as intervention and control groups. The data were collected using two questionnaires. Primarily, the Cardiac Depression Scale Inventory questionnaire was used to measure the degree of depression followed by PRCEDE Model-based educational questionnaire to identify the role of educational intervention on patients. The PRECEDE Model-based intervention composed of nine educational sessions per week (60 to 90 min each). The patients were followed up for two months post-intervention. Findings: Following the educational intervention, the mean score of Predisposing factors, Enabling factors, Reinforcing factors, and self-helping behaviors was significantly increased in intervention group compared to control group (p<0.001). Also, a significant difference associated with the mean score of depression level in patients was demonstrated between two groups following the educational intervention (p<0.001) Conclusion: The findings of current study confirmed the practicability and effectiveness of the PRECEDE Model-based educational program on preventing or declining the depression level in CABGS patients.
