Note. -2LL=Likelihood Statistic. χ2=Chi-square fit statistic. df=Degrees of freedom. AIC=Akaike’s Information Criterion. Best fitting model indicated in bold.
Overall fit of the model is determined by the difference in -2LL of the model and that of a saturated model.
χ2 difference between the Independent Pathway model and Common Pathway model.
χ2 difference between the full and reduced longitudinal models.
