A growing empirical literature supports contingency management (CM) as an efficacious treatment for substance use disorders, especially when reinforcers are immediate, frequent, and of sufficient magnitude on escalating schedules. However, in real world-practice, CM is often conducted in ways that are inconsistent with research protocols. One reason for these inconsistencies may be due to pragmatic challenges inherent in conducting CM. In this article, we described an outpatient CM treatment program for drug use disorders and several specific challenges associated with adherence to CM parameters from research protocols. Finally, we propose possible solutions for these challenges and discuss implications for practice.
