职业人群工作疲竭感问卷的信度与效度评估

目的 评价工作疲竭感问卷在职业人群中运用的信度与效度.方法 选用Maslach开发Boles修订的19个条目的工作疲竭感问卷,对458名在职职工进行调查.结果 问卷的内部一致性检验结果：全卷与3个子项（情感耗竭、人格解体、个体成就感）的Cronbach＇s α值介于0.82～0.85之间.因子分析提取得到3个公因子与原理论模型基本一致,分别代表情感耗竭、人格解体与个体成就感.运用协方差与方差分析,其工种对3个子项积分的差异有统计学意义（P＜0.01）,而不同性别间人格解体积分的差异与不同受教育程度间个体成就感积分的差异均有统计学意义（P＜0.01）.结论 简明工作疲竭感问卷是一较可靠、有效的测量工具,可用于职业人群的职业应激研究.

Reliability and validity of Burnout Questionnaire in occupational population

OBJECTIVE: To evaluate the reliability and validity of simple Burnout Questionnaire in occupational population. METHODS: A self-administered Burnout Questionnaire comprising 19 items was developed in light of Maslash Burnout Questionnaire and used for investigating 458 employees. RESULTS: Cronbach's alpha between total items of Burnout Questionnaire and each factor fell in between 0.82 and 0.85 through the consistency test. All 19 items of Burnout Questionnaire were subjected to factor analysis, and three latent factors were identified, wherein 56.3% of total variance could be explained. According to the contents described in the items and Maslash burnout theory, they were emotional exhaustion, depersonalization, and personal accomplishment. According to the covariance and the variance analysis, there was significant difference in the integral of the type of work among the three subitems (P < 0.01); there was significant difference in the integral of depersonalization between two sexes (P < 0.01); There were significant difference in the integral of the personal achievement among different level of education (P < 0.01). CONCLUSION: The reliability and validity of Burnout Questionnaire is acceptable and can be used for assessing burnout in occupational population.
