Correlation between stress, self efficacy and quality of life in patients with gallstone

Abstract

Objective To explore the effects of stress and self-efficacy on the quality of life in patients with gallstones and the effect relationship of self-efficacy in the quality of life and stress, and provide guidance for the health intervention of patients with gallstones. Methods Totally 362 patients with gallstones after operative that already returned to the community for 12 months were investigated, and their stress condition, self-efficacy and quality status of life were measured by the life events scale (LES), self-efficacy scale and gastrointestinal quality of life index (GIQLI). The effect relationship of self-efficacy in the quality of life and stress was analyzed. Results The self-efficacy played partial mediating effect between stress and quality of life. When the intermediary variables-self-efficacy sense was participated in, the regression coefficient between stress and quality of life was significantly reduced (β was reduced from -0.695 to -0.548). Self efficacy played regulating effect between stress and quality of life, which means that self efficacy sense × stress partial regression coefficient in the regression which regard the quality of life as the dependent variable can reach to a significant level (β=-0.086, P<0.05), and introduced interaction terms after new interpretation (△R2) also can reach to a significant level (△R2=0.017, P<0.05). Conclusions Self efficacy played the mediating effect and regulating effect in the relationship between stress and quality of life. Nursing staff can reduce the negative effects of stress events in patients′ quality of life through the interventions in patients′ self-efficacy.
