Abstract:
Objective To develop a military identity scale and to evaluate its reliability and validity.Methods The theoretical and structural models of the scale were determined based on literature review and interviews.An item pool was established,test items were compiled,and the basic items were formed after revision by experts.Several servicemen were selected.Sample 1 was used for item analysis and exploratory factor analysis,and sample 2 was used for confirmatory factor analysis and internal consistency test.The reliability of the scale was tested by Cronbach's α coefficient and split-half reliability.The construct validity was tested by correlation analysis and confirmatory factor analysis.The military job burnout scale was used as criteria to test the criterion validity.Results The scale finally included 23 items in 4 factors(cognition,affection,sense of adaptation,and efficacy),which explained 54.087%of the total variance.The Cronbach's α coefficient of the scale was 0.925,and the Cronbach's α coefficients of the 4 factors were 0.843,0.899,0.854,and 0.835,respectively.The split-half reliability of the scale was 0.873,and the split-half reliability of the 4 factors was 0.812,0.882,0.870,and 0.821,respectively.The scale had good construct validity(the goodness of fitting χ2/df was 1.978,the comparative fit index was 0.927,the growth fitting index was 0.928,the Tucker-Lewis index was 0.916,the root mean square error of approximation was 0.055,and the goodness of fit index was 0.896).Conclusion The military identity scale developed in this study has good validity and reliability,and can be used to evaluate the identity of servicemen in China.
