Investigating the Predictive Role of Health Beliefs and Cardiac Self-Efficacy in History of Tobacco Smoking in Patients with Coronary Artery Disease (CAD)

Self-efficacy is a person's confidence in his ability to control the disease and maintain his duties. Health beliefs include assessing the risk of a health problem and assessing the benefits and barriers to health behaviors. The purpose of this study was to investigate the predictive role of health beliefs and cardiovascular self-efficacy in smoking patients with coronary artery disease CAD).
In this cross-sectional study, 103 patients who were candidate of CABG and PTCA in Tehran Heart Center were selected by convenient sampling method. They were asked to complet the Sullivan`s cardiac self-efficacy questionnaire and researcher designed health belief questionnaire.
The result of Logistic regression analysis showed that from tow predictor variables, only cardiac self-efficacy able to predict smoking (β=0.14) in patients with CAD. The high value of Wald's statistic indicates the usefulness and potency of self-efficacy variables in predicting cigarette smoking. This finding suggests that the cardiac self-efficacy is one of the determinants of smoking in patients with CAD.
Therefore, it is necessary to pay special attention to increase self-efficacy of these patients in smoking cessation interventions and prevention.
The results of logistic regression analysis showed that only the self-efficacy of the two predictors was able to predict the history of smoking (β=-0.44) in CAD patients.
