Data were collected by trained interviewers who conducted in-person interviews using an electronic version of the Semi-Structured Assessment for Drug Dependence and Alcoholism (SSADDA). The SSADDA queries demographic information, lifetime diagnostic criteria for DSM-IV psychiatric disorders, and psychosocial history, including history of exposure to adverse events during childhood. A detailed history of substance use, including maximum number of drinks consumed in a 24-hour period, is also queried in the SSADDA. (Descriptions of SSADDA administration methods and reliability can be found in Feinn et al., 2009, Pierucci-Lagha et al., 2007, and Pierucci-Lagha et al., 2005).
