Other individuals will be recruited from the community for participation in the outpatient phase of the study who have responded to a radio ad, a UNC listserve ad, a flyer, have been referred by local clinicians or have otherwise become aware of the study. These prospective subjects will undergo a telephone screening interview. If they appear to meet criteria over the phone, they will be further screened during an outpatient clinic visit. They must sign the Breath Alcohol Policy.
