DSM-IV psychiatric disorders were assessed with the AUD and Associated Disabilities Interview Schedule (AUDADIS-IV) (Ruan et al. 2008). The individual psychiatric disorders assessed in NESARC that were analyzed in this study have test-retest reliabilities (kappa) that range from 0.40 to 0.77 (Ruan et al. 2008). We included past-year disorders of major depression, dysthymia, mania (bipolar I & II), generalized anxiety, post-traumatic stress, panic (with or without agoraphobia), social phobia, antisocial personality disorder, and four categories of past-year drug use disorder (cannabis, opiate [including heroin], cocaine, and “other” [including tranquilizer, sedative, amphetamine, hallucinogen, inhalant, and other]).
