Comparison of Model Fit for 2 Factor Models After Confirmatory Factor Analysis Based on Robust Measures of Weighted Least Squares
| Factor Model | df | χ2 | χ2/df | CFI | TLI | RMSEA | SRMR |
|---|---|---|---|---|---|---|---|
| Clinical Clusters [Strassman et al. (25)] | 2195 | 4298.14 | 1.96 | 0.921 | 0.918 | 0.077 | 0.088 |
| Eight Factors (Current Solution) | 3712 | 5849.62 | 1.58 | 0.937 | 0.935 | 0.066 | 0.078 |
n = 745.
CFI, comparative fit index; RMSEA, root-mean-square error of approximation; SRMR, standardized root mean residual; TLI, Tucker-Lewis fit index.
