Notes: df = degrees of freedom; CFI = robust version of the Comparative Fit Index; ΔCFI = differences between models (0 and 1, 1 and 2; 2 and 3) regarding robust CFI; RMSEA = robust version of the root mean square of approximation; ΔRMSEA = differences between models (0 and 1, 1 and 2; 2 and 3) regarding robust RMSEA
a = ΔCFI ≤ .010 supplemented by ΔRMSEA ≥ -.015 indicates non-invariance. √ marks invariance
