Four different sets of LCA models were examined including the following sets of disorders: Mental disorders commonly used in structural models of epidemiological studies [1-3]: Disorders targeted for these LCA analyses consisted of conditions diagnosed most frequently in the general population: specific phobia, social phobia, agoraphobia, panic disorder, post-traumatic stress disorder (PTSD), major depressive disorder, generalized anxiety disorder (GAD), dysthymia, alcohol dependence, drug dependence, and conduct disorder. Separate models of these disorders were examined in both the NCS and NCS-R.Next, LCA models for both samples were rerun after adding diagnoses of both bipolar disorderi. In each case, profiles obtained from optimal LCA solutions were compared to the models obtained in the previous step.
