Table 3. Goodness of fit indices for the four models tested for confirmatory factor analysis.
| Model | Chi-square | SRMR | RMSEA | CFI | TLI |
|---|---|---|---|---|---|
| Unidimensional | χ = 906.14, df = 135, p < .001 | 0.13 | 0.15 | 0.77 | 0.74 |
| Separate factors | χ = 375.09, df = 129, p < .001 | 0.09 | 0.09 | 0.93 | 0.91 |
| Second-order | χ = 483.78, df = 131, p < .001 | 0.10 | 0.11 | 0.89 | 0.87 |
| Bifactor | χ = 292.98, df = 117, p < .001 | 0.08 | 0.08 | 0.95 | 0.93 |
