AIC, Akaike information criterion; BIC, Bayesian information criterion; VLMR, Vuong-Lo-Mendell-Rubin; BLRT, Bootstrapped likelihood ratio test.

a

Chi-square statistic for the VLMR and the BLRT. When non-significant (p > .05), the VLMR and the BLRT test provide evidence that K-1 class model fits the data better than the K-class model.

b

3-class model was selected, based on its having smaller BIC than the 2-class and 4-class model, and non-significant VLBR and BLRT in the 4-class model.
