a Latent class analysis with 4 latent subgroups fit better than the models with 1, 2, 3, and 5 latent subgroups based on fit statistics (i.e., lower values for Akaike information criterion, Bayesian information criterion (BIC), and sample-size-adjusted BIC, higher values for average classification probability, and a low P-value for the Lo–Mendell–Rubin likelihood ratio test, indicating that the 3-class model had to be rejected in favor of a model with at least 4 classes).
