For both studies, treatment-seeking participants with AUD were recruited from the community through advertising on the web, newspapers and via flyers posted in the Greater New Haven area. For both studies, all participants provided written informed consent and the research was approved by the Yale University Human Investigation Committee. Trained research assistants completed a phone screen with participants to determine preliminary eligibility. Participants were then invited to the Center where they received a complete description of the study, provided their written informed consent, and completed an in-person screening. During these appointments, participants completed a series of baseline assessments and provided urine samples to verify recent alcohol and drug use history.
