Note: MG Multiple group, M1 model 1, χ2 indicates MLR chi-square value, df degrees of freedom, CFI confirmatory fit index, TLI Tucker-Lewis index, No. FParms Number of free parameters, RMSEA Root-mean-square error of approximation, χ2 SCF scaling correction factor, CD difference test scaling correction, TRd Satorra-Bentler scaled χ2 difference test, df diff difference in degrees of freedom between the nested model and the comparison model, p (significant at 0.05). M1 = Configural model, M2 = Factor loadings constrained equal, M3 = Factor variances constrained equal, M4 = Factor loadings constrained equal, M5 = Intercepts constrained equal, M6 = Latent means (factor means and variance estimated for group ‘boy’ only, ‘grade 5_6’ only). There were no residual covariance’s to constrain equal in the configural model
