Among respondents who reported alcohol use in the past year, the DSM-IV criteria for alcohol abuse (4 criteria) and dependence (7 criteria) were assessed by questions related to the occurrence of specific symptoms during the past 12 months. These symptom questions are shown in the appendix and are organized by the DSM-IV criteria for alcohol abuse and dependence based on algorithms provided in the NSDUH public use data documentation (Substance Abuse and Mental Health Services Administration, 2006)
