LPA results demonstrated that comparative fit indices continued to improve as additional profiles were added, though aLMR suggested 3-profile prior to Covid-19 and 4-profile post-Covid-19 measurement models (Table 2).
Interpretability of the models support the utilization of 3-profiles prior to Covid-19: the 4-profile prior to Covid-19 results simply break up the below clinical concern profile into two similar below clinical concern profiles. Comparing interpretability of the during Covid-19 3-profile and during Covid-19 4-profile results supports the 4-profile solution given the qualitatively different profiles. Therefore,a 3-profile prior to COVID-19 and 4-profile during COVID-19 model without configural invariance (i.e., LPA profiles without the same number of profiles across timepoints) was selected as the final measurement model (Figure 1).
