Burnout (BT) is a vital determinant of work effectiveness and a well-studied psychological construct. The dominant theoretical perspectives have defined BT via the proposed dimensional structures and have provided the corresponding instruments for measuring them. The present endeavor adopts the Oldenburg Burnout Inventory (OLBI), as its purpose is to examine the psychometric properties of a short version for the Greek teachers and to find differences across their individual characteristics. The Greek short version of OLBI comprises two dimensions: Disengagement (four items) and Exhaustion (five items), with reliability measures utilizing Cronbach's alpha and McDonald's omega: Exhaustion ( = 0.810/ = 0.823) and Disengagement ( = 0.742/ = 0.756). Confirmatory factor analysis showed an adequate fit of the measurement model: = 320.291, = 26, < 0.001; = 0.970; = 0.958; = 0.068; 90% CI of RMSEA = [0.062; 0.075]; = 0.067; = 0.967; = 0.986]. The proposed model is extracted after two studies ( = 134, = 2437). The novel aspect of this endeavor is the measurement invariance explored across selected demographic variables. The findings supporting the measurement invariance make an essential contribution to the field, and the implications for educational research are provided along with a concise presentation of theoretical issues.
职业倦怠（BT）是工作效能的一个重要决定因素，也是一个经过充分研究的心理结构。主流理论观点通过所提出的维度结构对职业倦怠进行了定义，并提供了相应的测量工具。本研究采用奥尔登堡职业倦怠量表（OLBI），其目的是检验希腊教师简版量表的心理测量特性，并找出不同个体特征之间的差异。希腊语版的OLBI简版包括两个维度：脱离（四个项目）和疲惫（五个项目），使用克朗巴哈系数和麦克唐纳欧米伽系数进行信度测量：疲惫（=0.810/=0.823）和脱离（=0.742/=0.756）。验证性因素分析表明测量模型拟合良好：=320.291，=26，<0.001；=0.970；=0.958；=0.068；RMSEA的90%置信区间=[0.062；0.075]；=0.067；=0.967；=0.986。所提出的模型是在两项研究（=134，=2437）之后提取的。这项研究的新颖之处在于探索了所选人口统计学变量的测量不变性。支持测量不变性的研究结果对该领域做出了重要贡献，并在简要介绍理论问题的同时提供了对教育研究的启示。
