军人职业倦怠量表的信效度检验

目的 研制军人职业倦怠量表,并对其信度、效度进行检验.方法 采用随机整群抽样方法 ,选取1000名健康官兵,并分为A(500名)、B(500名)两组.用研制的军人职业倦怠量表对两组被试进行测试.对其中的280人同时使用本量表和工作倦怠问卷进行施测;对收集的A组数据进行探索性因素分析和相关分析,B组数据进行验证性因素分析.结果 经相关分析发现:总量表的Cronbach'α系数为0.917,各因子的Cronbach'α系数为0.719～0.847;总量表的分半信度为0.920,各个因子的分半信度为0.723～0.867.总量表与各分量表之间的相关系数为0.731～0.808(P＜0.01),各分量表之间的相关系数为0.386～0.627(P＜0.01).经探索性及验证性因素分析发现:所测数据与理论模型(成就感、躯体化、自我评价、人际关系、消极怠工);相一致,拟合指标的卡方值为771.914,自由度(DF)为395,相对卡方值为1.954,P=0.000,近似误差均方根为0.044,拟合优度指数、比较拟合指数、增值拟合指数分别为0.904,0.919,0.920.军人职业倦怠量表总分及各因子分与工作倦怠问卷的总分及各因子分之间具有显著的相关性.结论 自行研制的军人职业倦怠量表具有较好的信度和效度.

The examination of the reliability and validity of the job burnout scale for military personnel

Objective To develop the job burnout scale for military personnel and examine the reliability and validity of this scale. Methods A total of 1000 military personnels were chosen by random cluster sampling to outline the Job Burnout Scale for Military Personnel, with the subjects divided into group A and group B, 280 of them were tested by this scale and Chinese Maslach Burnout Inventory simultaneously (CMBI), In group A ( n=500 ) Exploratory Factor analysis and Correlation analysis were used, and in group B ( n = 500) Confirmatory factor analysis was used. Results The results of correlation analysis indicated that the Cronbach'α of total scale was 0.917, and that of subscales was 0.719 ～ 0.847; split-half reliability coefficient of total scale was 0.920, and that of subscales was 0.723 ～ 0.867. The correlation coefficient of total scale scores and each factor was 0.731 ～ 0.808 (P＜0.01 ) ,and the correlation coefficient ranged from 0.386 to 0.627 between the factors(P ＜ 0.01 ). According to the results of exploratory and confirmatory factor analysis, the sample data fitted better to the hypothesized structure of theoretical model ( Sense of achievement, Somatization, Self-assessment, Human relation, Demotivation) and the indexes of Chi-Square was 771. 914, the degrees of freedom was 395, the probability level was 0.000, the relative Chi-Square was 1.954, the root mean square error of approximation (RMSEA) was 0.044, and the goodness of fit index ( GFI ), comparative fit index ( CFI ), incremental fit index ( IFI ) were 0.904,0.919, 0.920 respectively. The correlation was significant between this scale and CMBI. Conclusion The Job Burnout Scale for Military Personnel has good reliability and validity.
