Brief announcements were made following educational lectures at four residential substance use treatment programs in Western New York. The programs have an 11 to 21-day average length of stay and use an abstinence-based model. Patients who were interested came forward and were scheduled for a 1:1 screening appointment. Participation rates at the sites ranged from 47% to 81%. The study was approved by the Internal Review Boards of the two participating universities and a Federal Certificate of Confidentiality from the National Institutes of Health was obtained.
