Correlation analysis of self-efficacy and quality of life among patients after coronary artery bypass grafting

Abstract

Objective To address the correlation between self-efficacy and quality of life in patients after coronary artery bypass graft. Methods A total of 88 patients in our hospital were investigated by using general data questionnaire, Barnason self-efficacy scale and concise health questionnaire (MOS-SF 36) at 2 weeks, 6 weeks and 3 months after coronary artery bypass graft. Results The self-efficacy scores were (42.8±5.4) at 2 weeks after operation, (44.5±4.2) at 6 weeks after operation and (47.6±5.6) at 3 months after operation, and the scores of quality of life were (73.7±11.4) at 2 weeks after operation, (85.9±10.6) at 6 weeks after operation and (93.9±16.2) at 3 months after operation (F=3.452, P<0.05). After operation, the self-efficacy increase gradually, and the difference was statistically significant. The scores of quality of life were (73.7±11.4) at 2 weeks, (85.9±10.6) at 6 weeks, and (93.9±16.2) at 3 months after operation, and there was a positive correlation between self-efficacy and quality of life (r=0.411, 0.447, 0.307, respectively; P<0.01). Conclusions The quality of life and self-efficacy of patients after coronary artery bypass surgery are improved, and the two are positively correlated. Nursing staff should be based on principles of self-efficacy theory to strengthen the nursing work which may improve the patient′s self-efficacy and the quality of life.
