Table 3.

Comparison of the empirical, latent factor (LFA), latent class (LCA) and factor mixture models (FMM) by way of Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC) and sample size adjusted Bayesian Information Criterion (sBIC). LFA analyses also include oblique (r) solutions. Best fitting model is based on consistent performance across three fit indices. Bolding indicates top two under each index.
