Table 1.
Model fit indices derived from latent class analysis on models with 1–5 classes.

AIC, Akaike information criterion; BIC, Bayesian information criterion; aBIC. sample size adjusted BIC; LMR, Vuong-Lo-Mendell-Rubin likelihood ratio test; BLRT, bootstrapped likelihood ratio test. The three latent classes were regarded as the best model, highlighted in bold.
