Note: T1 = time point 1; T2 = time point 2; T3 = time point 3; T4 = time point 4. For Waves 2–4, in the 3- and 4-class solutions, the best loglikelihood was not replicated, suggesting that standard errors may not be trustworthy. Additionally, for waves 3 and 4, the 3- and 4-class models each had one class that represented less than 5% of the overall sample.
