| Model | Test | χ2 | Df | CFI | ΔCFI | RMSEA | ΔRMSEA | MI Test a |
|---|---|---|---|---|---|---|---|---|
| Model 0 | Configural invariance | 928.3 | 404 | 0.914 | 0.059 | Y | ||
| Model 1 | Weak invariance | 948.6 | 419 | 0.914 | 0.000 | 0.058 | -0.001 | Y |
| Model 2 | Strong invariance | 1025.0 | 455 | 0.907 | -0.007 | 0.058 | 0.000 | Y |
| Model 3 | Strict invariance | 1067.4 | 478 | 0.904 | -0.003 | 0.057 | -0.001 | Y |
df = degree of freedom; CFI = robust version of the Comparative Fit Index; ΔCFI = differences between models (0 and 1, 1 and 2, and 2 and 3) in robust CFI; RMSEA = robust version of the root mean square of approximation; ΔRMSEA = differences between models (0 and 1, 1 and 2, and 2 and 3) in robust RMSEA;
a = ΔCFI ≤ 0.010 supplemented by ΔRMSEA ≥ -0.015 indicates non-invariance.
Y marks invariance.
