III.3.2 Structural Model The analysis was continued with a common set of overall fit measures to assess the measurement model as a whole: the ratio of χ² to degrees-of-freedom (df), the goodness-of-fit index (GFI), the adjusted goodness-of-fit index (AGFI), the normalized fit index (NFI), the non-normalized fit index (TLI), the comparative fit index (CFI), the root-mean square residual value (RMSEA), and the standardized root-mean residual value (SRMR). Table III-3 summarizes the m...
