Abstract: Objective To investigate the relationship between self-efficacy and quality of life/negative emotion in peritoneal dialysis (PD) patients. Methods Sixty-eight patients with the dialysis age less than 12 months and treated in the period from Jan. 2014 to Dec. 2014 were enrolled in this study. These patients were evaluated by self- efficacy scale, World Health Organization the quality of life- BREF (WHO QOLBREF), Hamilton anxiety scale (HAMA), and Hamilton depression scale (HAMD). The relationship between self-efficacy and quality of life/negative emotion in PD patients were then analyzed. Results The total scores of physical dimension, psychological dimension, environmental dimension, social dimension, and the total scores of quality of life were higher in the high self-efficacy group (≥7) than in the low self-efficacy group (＜7), while the scores of HAMA and HAMD were lower in the high self-efficacy group than in the low self-efficacy group. Pearson correlation analysis found that self-efficacy was positively correlated with psychological dimension (r=0.325, P=0.012), social dimension (r=0.412, P=0.000), and total scores of quality of life (r= 0.347, P=0.005), and was negatively correlated with the scores of HAMA (r=-0.348, P=0.010) and HAMD (r=-0.392, P=0.008). Conclusions The self-efficacy of PD patients was closely related to quality of life/negative emotion. Through health education in the clinical nursing practice, their self- efficacy can be enhanced, the negative emotion can be diminished, and the quality of life can be improved.
