The χ² values were significant for all models; NNFI * = robust version of the non-normed fit index; CFI * = robust version of the comparative fit index; RMSEA * = robust version of the Root Mean Square Error of Approximation; 95% CI = 95% confidence interval of the RMSEA; AIC * = Robust version of the Akaike Information Criterion; CAIC * = Robust version of the Consistent Akaike Information Criterion.
