Metrics of Adequacy and Fit of Latent Class Model
	Group Average Posterior Probability	Odds Ratio for Correct Classification	Estimated Group Distribution Based on Using Maximal Probability Rule	Estimated Group Distribution Based on Initial Model	Entropy
Livelihood and mobility	0.983	128	0.311	0.306	0.858
Clinic accessibility	0.940	48	0.247	0.289
Mobility and family	0.811	12	0.270	0.219
Doubting need for HIV care	0.899	80	0.100	0.102
Multidimensional barriers to care	0.951	252	0.072	0.083

Good model fit indicated by 1) average posterior probability greater than 0.7 for each group, 2) odds ratio of correct classification greater than 5 for each group; 3) close correspondence between the estimated group distribution based on using posterior probabilities and the maximal probability rule compared with the estimated group distribution from the initial model; and 4) an entropy greater than 0.8.
