Therapists to Administer Contingency Management-Therapist Phase - 1

The purpose of this study is to train therapists to administer contingency management (CM).
This project will train up to 42 community-based treatment providers about the rationale for
and the specifics of administering CM. Initial training will occur in 2-day workshops,
followed by weekly supervision in delivery of CM with test cases. We expect that the
majority of therapists will achieve high levels of competence and adherence in administering
CM treatment within 3-5 test cases, as measured by ratings of audiotapes. To examine the
efficacy of CM, each therapist who achieves adherence and competence in delivering CM will
administer standard treatment alone or standard treatment plus CM to substance-abusing
outpatients. In the CM condition, patients will have the opportunity to win prizes ranging
in value from $1 to $100 for submission of negative samples, and the treatment will be in
effect for 12 weeks. In total, up to 200 patients will be randomly assigned to one of the
two conditions. A research evaluator will conduct follow-up assessments, scheduled for 3, 6
and 9 months after treatment initiation.
