      This quasi-experimental research aimed to examine the effect of an enhancing self-efficacy in early
cardiac rehabilitation program on patients’ physical outcomes and anxiety after coronary artery bypass graft
surgery at hospital in Thailand from April 2017 to January 2018. Purposive sampling selection was employed
and the individuals were randomly assigned into intervention and control groups, with 20 persons in each
group. The research instruments were composed of an enhancing self-efficacy in early cardiac rehabilitation
program, a booklet, a video demonstrating muscle relaxation, breathing exercises, and early mobilization.
The data collection using the instruments included the following: the demographic data, the Lung Function
Scale (LFS), the Postoperative Pulmonary Complications Scale (PPCS), the Early Mobilization Competence
Assessment Scale (EMCAS), the Numerical Rating Pain Scale (NRPS) and the Anxiety to CABG Surgery
Scale. The data were analyzed using the Mann-Whitney U test. The results revealed the following: the
median score of patients’ physical outcomes such as LFS and EMCAS on the third day post-operation
and the first week after hospitalization of the experimental group were statistically significantly higher than
control group (p< .01 and p< .05 respectively), the PPCS and the NRPS of the experimental group were
statistically significantly lower than the control group (p< .05 and p< .01 respectively). The anxiety score of
the experimental group was statistically significantly lower than the control group (p< .01).
        The effects of an enhancing self-efficacy in early cardiac rehabilitation program had effects on the
CABG surgery patients by increasing their perceived self-efficacy in terms of early mobilization and having
good recovery outcomes that can use for cardiac rehabilitation coronary artery bypass graft surgery.
