a smaller number. Substantive interpretability was evaluated by examining patterns of psychiatric disorder probabilities within and across classes to determine if the patterns appeared theoretically meaningful (e.g. consistent with prior conceptions of how psychiatric disorders relate to one another) versus idiosyncratic. After selecting the appropriate LCA measurement model, we used Mplus to calculate model-estimated descriptive statistics for gender, number of comorbid disorders, and AUD severity across empirically identified psychiatric comorbidity profiles.
