self-efficacy, functional capacity, post coronary artery bypass graft


This quasi-experimental research aimed to study the effects of self-efficacy program on functional capacity among patients with post coronary artery bypass graft. Sample was under postoperative coronary artery bypass graft, both male and female, aged 31-59 years, admitted in Surgical Out Patients Department, Ramathibodi Hospital, purposive selection and allocate to an experimental group (n=21) and a control group (n=21) with matching technique for gender, age, and left ventricular ejection fraction efficiency (LVEF). The tools were composed of the functional capacity evaluation form the 6-minute walk test, self-efficacy program for 8 weeks post discharge, perceived self-efficacy questionnaire and the home activities and exercises record form after discharge. Data were analysis by using descriptive statistic and t-test.

 The results revealed that: the mean score of functional capacity after treating with self-efficacy program in the experimental group was higher than that in the control group (t = 2.958, p<.05).

This study suggests that self-efficacy program should be applied for among patients with post coronary artery bypass graft in order to increase functional capacity continuously.
