CFA Confirmatory Factor Analysis, GFI Goodness-of-Fit Index, AGFI Adjusted Goodness-of-Fit Index, NFI Normed Fit Index, CFI Comparative Fit Index, SRMR Standardized Root Mean Square Residual, IFI Incremental Fit Index, RFI Relative Fit Index, TLI Tucker–Lewis Index, RMSEA Root Mean Square Error of Approximation, χ2/DF Chi-squared Degree-of-Freedom Ratio
Indexes values of GFI, AGFI, NFI, RFI, IFI, TLI, and CFI ≥ 0.90 indicate ideal or acceptable model fitting. Indexes values of SRMR or RMSEA ≤ 0.08 indicate ideal or acceptable model fitting. The value between 1.00 and 3.00 is needed for χ2/DF to indicate a good model fitting, or else it is not satisfactory
The indexes values indicated an ideal or acceptable or a good model fitting are given bold
