During the first week of the inpatient stay, subjects underwent an initial medical evaluation and provided demographic and psychosocial history. In the second week, they were interviewed using the Structured Clinical Interview for DSM-IV21 to assess psychiatric and substance abuse diagnoses. Baseline alcohol- and drug-related assessments, including alcohol use for the 90 days prior to admission, were also completed. Social drinking controls completed demographic, diagnostic, and alcohol-related assessments and script development sessions in 2 to 3 assessment appointments and were then admitted for a 3-day hospital stay to the Hospital Research Unit at Yale-New Haven Hospital for participation in the laboratory study. During this period, they were required to stay on the unit, within a similar controlled environment as that of the alcohol patients.
