The range of Subscales Cronbach's alpha coefficients varied from 0.8 to 0.91, and the Cronbach's alpha coefficient of the whole scale was 0.90. The factor structure of the 4-factor and 3-factor model scale was explored through exploratory factor analysis and confirmatory factor analysis. The results of the exploratory factor analysis and confirmatory factor analysis of the model 3 had a more acceptable fit.
