We used a revised version of the Timeline Followback (TLFB) procedure (Sobell and Sobell, 1992) to assess lifetime history of alcohol use and drinking patterns (such as onset age, drinking and intoxication experiences). For the purposes of this history-taking, a standard drink was defined as one beer or wine cooler, one glass of wine, or one 1.5-oz shot of liquor (alone or in a mixed drink). The Schedule for Affective Disorders and Schizophrenia for School-Aged Children (6–18 years) Lifetime Version (K-SADS-PL; Kaufman et al., 1997), a semi-structured clinician-rated diagnostic scale, was used to determine presence of a DSM-IV-defined AUD.
