Text

Prevalences of abuse and dependence criteria as well as craving among current drinkers were estimated using SUDAAN software (Research Triangle Institute, 2004). In addition, within the portion of the sample diagnosed with DSM-IV alcohol dependence, we examined the clinical correlates of endorsing craving. Odds ratios were estimated using logistic regression. Finally, we constructed two diagnoses, one that corresponds to current DSM-IV criteria, and one that includes craving but leaves the threshold for diagnosis at ≥3 criteria. Prevalence and clinical covariates of these two diagnoses were estimated to determine the concurrent validity of a diagnosis that includes craving.
