To evaluate the psychometric properties of the Chinese (mainland) version of Job Content Questionnaire (JCQ), this validation study was conducted in university hospitals among 193 men and 581 women health care workers. The Cronbach's alpha coefficients for decision latitude, psychological job demands and social support ranged from 0.56 to 0.82, which indicated that psychological job demands had lower internal consistency. The decision latitude displayed a negative correlation with psychological job demands and a positive correlation with social support. Exploratory factor analysis showed 3 meaningful factors that could explain the 3 theoretical dimensions of job strain model. Apart from some uncertainty over psychological job demands particularly, it is concluded that the Chinese (mainland) version of JCQ is a reliable and valid instrument for measuring job stressors, and is applicable to Chinese working population.
为评估中文版（中国大陆版）工作内容问卷（JCQ）的心理测量学特性，本验证性研究在大学医院中对193名男性和581名女性医护人员开展。决策自由度、心理工作要求和社会支持的克朗巴哈α系数在0.56至0.82之间，这表明心理工作要求的内部一致性较低。决策自由度与心理工作要求呈负相关，与社会支持呈正相关。探索性因素分析显示有3个有意义的因素，可解释工作压力模型的3个理论维度。特别是除了心理工作要求存在一些不确定性外，得出的结论是，中文版（中国大陆版）JCQ是一种测量工作压力源的可靠且有效的工具，适用于中国工作人群。
