Patients were categorized as having past year DSM-IV AUD using standard DSM-IV criteria: 3 or more criteria for alcohol dependence or 1 or more criteria for alcohol abuse for those who did not meet alcohol dependence criteria. Patients were categorized as having a DSM-5 AUD if they met 2 or more of the 11 DSM-5 criteria (Fig. 1). The severity of DSM-5 AUD is not reported because it may be under-estimated in patients who met DSM-IV dependence criteria, because they were not asked the 3 DSM-IV abuse questions included in the 11 DSM-5 criteria for AUD.
