Summary
The purpose of this study is to compare voucher-based contingency management (CM) procedures to a lower-cost CM system that provides opportunities to win prizes. Cocaine-dependent outpatients are randomly assigned to (a) standard treatment, (b) standard treatment plus voucher CM for abstinence, defined by negative breath and urinalysis test results, or (c) standard treatment plus prize CM for abstinence, defined by negative breath and urinalysis test results. Urine and breath samples are collected 3x/week during Weeks 1-3, 2x/week during Weeks 4-6 and 1x/week during Weeks 7-12. Follow-up interviews are conducted 1,3,6 and 9 months following intake during which substance use and psychosocial functioning are assessed.
