The Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM IV version (AUDADIS-IV), a structured diagnostic assessment tool, was administered by trained lay interviewers in the NESARC study. The AUDADIS-IV has demonstrated good reliability and validity for detecting psychiatric disorders in a community sample. The NESARC data set contains diagnostic variables derived from AUDADIS-IV algorithms and based on DSM-IV criteria. The data contain diagnostic variables for major depression, dysthymia, mania and hypomania, panic disorder with and without agoraphobia, social phobia, simple phobia, generalized anxiety disorder, alcohol abuse and dependence, drug abuse and dependence, and nicotine dependence. We used lifetime measures of these disorders with substance and illness-induced symptoms excluded. Seven DSM-IV Axis II disorders were also assessed with the AUDADIS-IV: antisocial, avoidant, dependent, histrionic, obsessive-compulsive, paranoid, and schizoid personality disorders. The AUDADIS-IV has shown good to excellent reliability in assessing psychiatric disorders in community samples (Grant et al. 1995).
