Alcohol initiation and dependence, as well as ages of onset, were assessed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule- DSM IV Version (AUDADIS-IV), which was administered through a structured computer-assisted personal interview (CAPI) (Grant et al., 2003; Grant et al., 1995). The AUDADIS assesses alcohol and other drug consumption data as well as selected Axis I and Axis II psychiatric disorders.
