Basically I do LCA, followed by some kind of analysis intended to validate the solutions. For example, I would create latent class solutions for each gender based on four dichotomic indicators of psychosis. Next, I would look at the interaction of current psychiatric status (the classes) and past psychiatric diagnosis to predict institutional treatment use (logit or logistic models). poLCA is a little limited for this purpose; I would have to use it in combination with some other package. For example, it doesn't provide residuals for the indicators, or the Cressie-Read statistic.
