Abstract:
Objective:To preliminarily establish a measurement model of life stress scale for submariners.Methods:The research hypothesis that the structure of life stress scale for submariners includes four dimensions and 92 items was put forward by literature review，referencing existing stress scales，personal interviews，and expert evaluation. On the basis of the questionnaire survey among 562 submariners，exploratory factor analysis and confirmatory factor analysis were used to test the hypothesis.Results:Exploratory factor analysis showed that the structure of life stress scale for submariners includes six dimensions，i.e.，noise and vibration stress，daily life stress，management stress，family stress，social isolation stress，and self-management stress，and 32 items in total. The results of confirmatory factor analysis showed that the fitness index of the model reached the standard of good after modification（ χ2/df=1.435，GFI=0.849，CFI=0.959，RMSEA=0.045，IFI=0.960，TLI=0.954，NFI=0.878），indicating that the measurement model has a good external quality. Moreover，each latent variable had good component reliability and mean variance extraction（CR：0.854-0.929，AVE：0.500-0.688），indicating that the internal quality of the measurement model and the latent trait of latent variables were good. Conclusion:The structure of life stress scale for submariners includes six dimensions. The correlation among latent variables in the measurement model shows that these six dimensions are a whole of mutual interaction and the structure of the scale is reasonable.
