Summary

This study tests the effectiveness of two 24 month, telephone-based adaptive continuing care interventions for patients with cocaine dependence. The two interventions are predicted to produce better drug use outcomes than standard care. Furthermore, the intervention that also includes monetary incentives for continued participation is hypothesized to produce better retention and drug use outcomes than the intervention without incentives. Economic analyses will determine the cost-effectiveness and benefit-cost of the interventions relative to standard care, and to each other.
