Depression is among the most important barriers to proper treatment ofcardiac patients. It causes failure in accepting their conditions, decreases their motivation infollowing the therapeutic recommendations, and thus negatively affects their functionality andquality of life. The present study aimed to investigate the effects of an educational programbased on Predisposing, Reinforcing, Enabling Constructs in Educational Diagnosis andEvaluation (PRECEDE) model on depression level in coronary artery bypass grafting (CABG)surgery patients.
This was a quasi-experimental study in which 54 post-bypass surgery patients ofIsfahan Cardiovascular Research Center were investigated. The patients were randomly dividedinto 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 followedby PRECEDE model-based educational questionnaire to identify the role of the educationalintervention on patients. The PRECEDE model-based intervention composed of 9 educationalsessions per week (60-90 minutes each). The patients were followed up for two months postintervention.
Following the educational intervention, mean scores of predisposing, enabling,and reinforcing factors, and self-helping behaviors significantly increased in the interventiongroup compared to the control group (P < 0.001). In addition, a significant difference in meanscores of depression was observed between the two groups following the educationalintervention (P < 0.001).
The findings of the current study confirmed the practicability and effectivenessof the PRECEDE model-based educational programs on preventing or decreasing depressionlevels in CABG patients.
