采用LISREL结构方程模型对Maslach职业倦怠量表（MBI）的因素结构进行研究。在MBI的三个因素中，情绪耗竭是最强劲的，其次是去人格化，而个人成就因素表现较弱。本文以197名护士为样本，建立了一种新的测量模型，包括情绪耗竭和去人格化两个维度，分别用5个和2个经验MBI指标进行测量。对三个样本（即一个护士校准样本和两个由医院实验室技术人员和医院管理人员组成的有效样本量为445的验证样本）的双因素模型的不变性检验产生了良好的拟合。双因素模型的心理测量特性评估产生了(1)与MBI最初指定的情绪耗竭和去人格化量表文献报道的内部一致性，以及(2)与标准变量的相关性，这些变量都在预期的方向和幅度上，与最初指定的量表产生的相关性相当。讨论了双因素模型在职业倦怠研究中的理论意义。
Structural equation modelling with LISREL was used to investigate the factor structure of the Maslach Burnout Inventory (MBI). Emotional exhaustion was the most robust of the MBI's three factors, followed by depersonalization, while the personal accomplishment factor performed weakly. A new measurement model was developed in a sample of 197 nurses consisting of the emotional exhaustion and depersonalization dimensions, which were measured with five and two empirical MBI indicators, respectively. A test of invariance of the two-factor model across three samples (i.e. one calibration sample of nurses, and two validation samples consisting of hospital laboratory technicians and hospital managers with an effective sample size of 445) produced a good fit for the proposed two-factor model. Assessment of psychometric properties of the two-factor model produced (1) internal consistencies comparable to those reported in the literature for the MBI's originally specified emotional exhaustion and depersonalization scales, and (2) correlations with criterion variables that were all in the expected direction and magnitude, comparable to those produced by the originally specified scales. Theoretical implications for the use of the two-factor model in burnout research are discussed.
