[目的]阐述结构方程模型的原理,并探讨医生工作压力和心理症状之间关系的合理结构方程模型模型。[方法]借助SAS9.0软件的CALIS过程,运用结构方程模型原理对医生工作压力和心理症状之间关系建立相应的结构模型与测量模型,用广义最小二乘法进行估计,并进行合理性检验和修正。[结果]模型的拟合优度指数(GFI)为0.969,均方根残差(RMR)为0.041,比较拟合指数(CFI)为0.955,表明拟合效果较好,并合理解释了医生工作压力和心理症状之间的关系。[结论]利用结构方程模型的优势,分析医生工作压力和心理症状之间的关系是可行的。
[Objective] To expound the principle of structural equation model and discuss the rational structural equation model of the relationship between doctors’ working pressure and psychological symptoms. [Methods] With the aid of CALIS process of SAS9.0 software, the structural model and the measurement model were established by using the principle of structural equation model to estimate the relationship between working pressure and psychological symptoms of doctors. The generalized least squares method was used to estimate the relationship and the rationality test Fixed. [Results] The model had a goodness of fit index (GFI) of 0.969, a root mean square residual error (RMR) of 0.041 and a comparative fit index (CFI) of 0.955, indicating that the fitting effect was good and explained the doctor’s work reasonably The relationship between stress and psychological symptoms. [Conclusion] It is feasible to analyze the relationship between doctors’ working pressure and psychological symptoms using the advantages of structural equation model.
