哥本哈根倦怠问卷的修订及信效度检验

Revision of the Copenhagen Burnout Inventory and its reliability and validity test

[目的]对哥本哈根倦怠问卷(the Copenhagen Burnout Inventory,CBI)进行修订并验证其信效度。[方法]采取便利抽样法,选取陕西省、四川省、湖北省10余所三级甲等医院487名医护人员,采用修订后CBI对其进行调查。[结果]CBI修订版内容效度指数为0.791。探索性因子分析提取3个公因子,累积方差贡献率为67.98%,因子载荷为0.515~0.830。验证性因子分析结果显示拟合指数理想。Cronbach'sα系数为0.936,各维度Cronbach'sα系数分别为0.853,0.932,0.907。条目与总分相关系数为0.530~0.852,条目间相关系数为0.430~0.653。重测Cronbach'sα系数为0.914。[结论]CBI修订版信效度良好,可以作为测量医护人员职业倦怠的评估工具。

Objective:To revise the Copenhagen Burnout Inventory(CBI),and test its reliability and validity.Methods:Totally 487 medical staff from more than 10 tertiary grade A hospitals in Shaanxi Province,Sichuan Province and Hubei Province,were selected by convenient sampling.Questionaire investigation was carried out by using revision of CBI.Results:The content validity index of revision of CBI was 0.791.The results of exploratory factor analysis showed that 3 common factors were extracted,whose cumulative variance contribution was 67.98%,and the factor loading ranged from 0.515 to 0.830.The results of confirmatory factor analysis showed that fitting index were good.The Cronbach's coefficient was 0.936.The Cronbach's coefficients of all dimension were 0.853,0.932 and 0.907 respectively.The correlation coefficient between items scores and total scores of revision of CBI ranged from 0.530 to 0.852.The item correlation coefficients ranged from 0.430 to 0.653.The retest Cronbach's coefficient was 0.914.Conclusion:Revision of CBI had good reliability and validity,which can be used as a tool for measuring the job burnout of medical staff.
