组织承诺在护士心理资本与工作疲溃感关系间的中介效应研究

Study on mediating effect of organizational commitment in relationship between psychological capital and job burnout of nurses

[目的]探讨心理资本对临床护士组织承诺的影响并建立结构方程模型,为临床护士管理提供依据。[方法]采用整群抽样,运用组织承诺量表、心理资本量表、工作疲溃感量表对临床1 145名护士进行调查。[结果]不同护龄、学历水平、月收入水平护士心理资本、工作疲溃感、组织承诺量表得分差异有统计学意义(P<0.05),临床护士护龄、学历水平、月收入水平、心理资本及组织承诺对工作疲溃感有预测作用,可以解释22.8%的变异量(P<0.05);结构方程模型显示,心理资本对工作疲溃感有直接效应(λ_1=-0.46,P<0.05),心理资本对组织承诺有直接效应(λ_2=0.72,P<0.05),组织承诺对工作疲溃感有直接效应(λ_2=-0.36,P<0.05),心理资本通过组织承诺对工作疲溃感有间接效应(λ_2=-0.26,P<0.05),心理资本通过直接效应和组织承诺的间接效应解释临床护士工作疲溃感28.47%的变异量。[结论]心理资本因素对临床护士工作疲溃感有一定的影响,临床管理者应运用适宜的干预措施提高护士心理资本,从而提高组织承诺,降低护士工作疲溃感。

Objective：To probe into the effects of psychological capital on organizational commitment of clinical nurses and establish the structural equation model, to provide basis for clinical nurse management. Methods. A total of I 145 clinical nurses were investigated by using cluster sampling,organizational commitment scale,psychological capital scale and job burnout scale. Results：Nurses with different nursing age,education level,income level had different psychological capital,job burnout, organizational commitment scale score,The difference was statistically significant（P〈0. 05）. Nursing age, education level, monthly income level, psychological capital and organizational commitment of clinical nurse had some predicting effect on job burnout. It can explain the variation of 22.8% （P〈0. 05）. Structural equation model showed that psychological capital has direct effect on job burnout（λ1 =-0.46, P〈0. 05） ;psychological capital had a direct effect on organizational commitment（λ2 =0. 72,P〈 0.05） ;organizational commitment has a direct effect on job burnout（λ2 =- 0.36, P〈0. 05） ;through organizational commitment, psychological capital has a indirect effect on Job Burnout （λ2 =- 0.26, P〈0. 05） ;through direct effect and indirect effect of organizational commitment, psychological capital can explain the variance of clinical nurses job burnout 28.47 %. Conclusion：Psychological capital factors had a certain effect on clinical nursesjob burnout,clinical managers should use appropriate intervention measures to improve nurses＇ psychological capital, to improve the organizational commitment and reduce nurses＇job burnout.
