Purpose: The purpose of this study was to identify motivational factors that may influence health behaviors of patients with coronary artery disease. Methods: Structured questionnaires were used with a convenience sample of 164 subjects who were discharged from the hospital. The subjects were recruited for an interview at outpatient clinic in hospitals. The tools for the study were the motivational factors and health behaviors measure for the Elderly with cardiovascular disease. The data were analyzed using frequency, t-test, ANOVA, sheffe, Pearson correlation coefficient and stepwise multiple regressions. Results: There were significant correlations between motivational factors and health behaviors, ranging from r=.192 to .692. Stepwise multiple regression analyses indicated that 51% of variance in health behaviors was explained by self-efficacy and perceived benefits among four motivational factors(F=34.988, p<.01). Self-efficacy contributed the greatest amount of variance in health behaviors(${eta}=.467$), followed by perceived benefits(${eta}=.235$). Conclusions: The results of the study indicate that motivation, especially self-efficacy, was very important in predicting health behaviors of patients with coronary artery disease. Thus it would be necessary to include motivational factors in designing rehabilitation program for people with coronary artery disease.
