Structural equation model of SRH among Tibetan residents. Note: Values indicate standardized coefficients, ** P < 0.01, *** P < 0.001. The final structural model fit well with the data (χ²/df = 4.512, NFI = 0.919, GFI = 0.973, CFI = 0.935, IFI =0.935, TLI = 0.919, RMSEA = 0.036 and RMR = 0.041). The squared multiple correlation (R²) was 0.33, which indicates that the model explained 33% of the variance in SRH
