DSM-IV alcohol abuse/dependence criteria experienced in the last 12 months were generated from 34 symptom question in the Alcohol Use Disorder and Associated Disabilities Interview Schedule (AUDADIS). Although the DSM-IV classification was not published until 1994, all the specific diagnostic criteria for DSM-IV alcohol abuse and dependence were known prior to the fieldwork for NLAES and were incorporated into the AUDADIS. The reliability of AUDADIS diagnosis has been shown to be good to excellent (Canino et al., 1999, Chatterji et al., 1997, Grant et al., 2003, Grant et al., 1995, Hasin et al., 1997a, Hasin et al., 2006) and validity has been extensively documented (Canino et al., 1999, Cottler et al., 1997, Hasin, 2003, Hasin et al., 1997b, Hasin and Paykin, 1999, Hasin et al., 1999, Hasin et al., 1997c, Pull et al., 1997, Ustun et al., 1997, Vrasti et al., 1998).
