Summary for the goodness of fit statistics for models on the measurement invariance testing of gender.

configural invariance = all values are free, weak invariance = factor loadings are invariant, strong invariance = factor loadings and intercepts are invariant, strict invariance = factor loadings, intercepts, and error variances are invariant, χ2 = Chi-square, χ2DF = Chi-square / Degree of freedom ratio; CFI = comparative fit index, TLI = Tucker-Lewis index, RMSEA = root mean square of approximation; Comp = to which model the current one is compared to; Δχ2 = chi-square test difference, significance level is indicates; ΔCFI = comparative fit index difference; ΔRMSEA = root mean square error of approximation difference. *p < .05 **p < .01 ***p < .001 Summary for the goodness of fit statistics for models on the measurement invariance testing of gender.
