心理资本对护士工作满意度和工作绩效的影响：积极情绪的中介效应

The effect of psychological capital on nurses′job performance and satisfaction：the mediating role of positive emotion

目的：探讨心理资本对护士工作满意度和工作绩效的影响，以及积极情绪在其中的中介作用。方法采用多阶段抽样方法抽取安徽省8所医院的523名护士，采用心理资本量表、正性情绪量表、工作满意度量表和工作绩效量表进行调查，应用结构方程模型验证变量间的关系。结果护士心理资本与积极情绪、工作满意度、工作绩效均呈正相关，r=0.473、0.358、0.505，均P＜0.01，积极情绪与工作满意度、工作绩效也呈正相关，r=0.452、0.343，均P＜0.01。积极情绪在护士心理资本与工作满意度之间存在部分中介作用，中介效应占整体效应的61.5%（0.24/0.39）；积极情绪部分中介了护士心理资本对工作绩效维度中专业发展能力和科研创新能力的影响，中介效应分别占整体效应的10.0%（0.06/0.60）、12.9%（0.08/0.62）。结论护士心理资本通过直接路径影响工作满意度和工作绩效，还通过积极情绪部分中介作用的间接路径影响工作满意度和工作绩效维度中的专业发展能力和科研创新能力。

Objective To explore the effect of psychological capital on nurses′job performance and satisfaction and the mediating role of positive emotion. Methods 523 nurses employed in eight hospitals in Anhui province were selected through multistage sampling and interviewed using questionnaires . Structural equation modeling was used to test the proposed relationships. Results Nurses′psychological capital was significantly positive correlated with positive emotion (r=0.473), job performance (r=0.505) and satisfaction (r=0.358), all P<0.01. Nurses′positive emotion was also significantly positive correlated with job performance (r=0.343) and satisfaction (r=0.452) , all P<0.01. The mediating test showed that nurses′positive emotion acted as a partial mediator between psychological capital and job satisfaction while medium effect accounting for 61.5%(0.24/0.39) of the whole effect. Nurses′positive emotion also played a role of being a partial mediator between psychological capital and two aspects of job performance, professional development ability and scientific research innovation ability,while medium effect accounting for 10.0%(0.06/0.60) and 12.9%(0.08/0.62) of the whole effect, respectively. Conclusions Psychological capital affects nurses′job performance and satisfaction and suggests nurses′positive emotion play a role of being a partial mediator in this relationship.
