Note. NFI = normed fit index; TLI = Tucker–Lewis index; CFI = comparative fit index; RMSEA = root mean square error of approximation; CI = confidence interval; AIC = Akaike information criterion; BCC = Brown-Cudeck criterion; ECVI = expected cross-validation index; MECVI = modified expected cross-validation index. ^a Assuming unconstrained model to be correct. ^b Assuming measurement model to be correct.
