Note. χ² = chi-square; df = degrees of freedom; p = p value of the chi-square test; Δ χ² = p value of the chi-square difference test; NFI = Bentler-Bonett normed fit index; CFI = Comparative fit index ; RMR = root mean square residual ; RMSEA = root mean square error of approximation; CI = 90% confidence interval of RMSEA value.
