Table 4 Fit index values, acceptable levels, and interpretations
Model fit indices | Model fit index level | Acceptable level | Interpretation |
|---|---|---|---|
GFI | 0.982 | 0 (no fit) to 1 (perfect fit) | Values close to 0. 90 or 0.95 reflect a good fit |
AGFI | 0.952 | 0 (no fit) to 1 (perfect fit) | Value adjusted for df, with 0.90 or 0.95 a good model fit |
CFI | 0.954 | 0 (no fit) to 1 (perfect fit) | Values close to 0. 90 or 0.95 reflect a good model fit |
IFI | 0.959 | 0 (no fit) to 1 (perfect fit) | Values close to 0. 90 or 0.95 reflect a good model fit |
SRMR | 0.040 | < 0.05 | Values less than 0.05 indicate a good model fit |
RMSEA | 0.037 | < 0.05 OR 0.05 to 0.08 | Values less than 0.05 indicate a good model fit and values of 0.05 to 0.08 indicate a close fit |
