Information Criteria and model fit indices for best fitting model in bold. AIC, Akaike Information Criterion; BIC, Bayesian Information Criterion; SSBIC, Sample Size Adjusted Bayesian Information Criterion; LRT, Lo-Mendell-Rubin Test; BLRT, Bootstrap Likelihood Ratio Test. 1- to 4-class solutions were tested with linear and quadratic parameters.
