Objective To examine the reliability and validity of Chinese Military Job Burnout Scale (CMJBS). Methods A test with CMJBS was carried out on 1 292 armymen chosen by stratified cluster sampling, and 130 of them were also tested by Chinese Military Occupational Stress Scale (CMOSS). SPSS17.0 and Amos7.0 were used to examine the reliability and validity of CMJBS. Results The Cronbach's α coefficient of total scale of CMJBS was 0.844, and those of subscales of CMJBS were 0.683-0.800 (P<0.01); the split-half reliability of total scale was 0.834, and those of the subscales were 0.575-0.758 (P<0.01). The correlation coefficients between factors and total scale score were 0.655-0.809 (P<0.01); the correlation coefficients between total scale score of CMJBS and CMOSS was 0.538(P<0.01). The results of exploratory factor analysis showed that the scale of the entries in the collation and factors named were consistent. The results of confirmatory factor analysis showed a higher degree of accordance between the sample data and the hypothesized structure of factors, with the χ² statistic being 1 465.447 and RMSEA (root mean square error of approximation) being 0.060, and with TLI (Tucker-Lewis index), CFI (comparative fit index), IFI (incremental fit index) and GFI (goodness of fit index) being 0.949, 0.895, 0.915, and 0.893, respectively. Conclusion The reliability and validity of CMJBS meet standards for scale designing and can serve as a tool for measuring the job burnout of Chinese armymen.
