NESARC used the Alcohol Use Disorder and Associated Disabilities Interview Schedule–DSM-IV Version (AUDADIS-IV) to ascertain diagnoses of mood, anxiety, and substance use disorders. For this study, lifetime mood and anxiety disorders included major depressive episode, manic episode, dysthymia, hypomanic episode, panic disorder with or without agoraphobia, social phobia, specific phobia, and generalized anxiety disorder. The AUDADIS-IV is a structured interview that is designed to produce diagnoses of common mental and substance disorders and can be administered by lay interviewers [25–28]. To receive a DSM-IV diagnosis, participants had to endorse the DSM-IV symptom criteria for that disorder as well as affirming distress or social/occupational dysfunction as a result of the disorder. The AUDADIS-IV assesses both lifetime and past-year DSM-IV Axis I and substance use disorders, as well as lifetime history of select personality disorders (antisocial, avoidant, dependent, obsessive compulsive, paranoid, schizoid and histrionic personality disorders). The reliability and validity of AUDADIS-IV has been previously reported [23, 25–31].
