Note: χ ² = chi-square; df = degree of freedom;χ ² /df = The chi-squared/freedom ratio;RMSEA = Root mean square error of approximation; CFI = Comparative fit index; NFI = Normed fit index; IFI = Incremental fit index; AIC = Akaike information criteria;ECVI = Expected cross-validation index.
The chi-square deference (Δχ ²) tests are compared with the unconstrained model (baseline model).
