Covariance-based structural equation modeling (CB-SEM) analysis of the direct and indirect effects among variables. Results of model fitting: χ2 = 15.324; Probability level = 0.501; df = 16; GFI = 0.943; RMSEA = 0.000; AIC = 73.32. All the paths in the model were significant, and the standardized coefficients were listed on them. The thickness of the solid arrows reflected the magnitude of the standardized SEM coefficients, the red solid line represented the positive effect while the blue solid line represented the negative effect
