Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Contingency management (CM) is a demonstrably efficacious intervention for substance abuse and dependence. Although CM protocols have employed a variety of reinforcers, they have almost exclusively relied upon non-cash privileges (e.g., take-home methadone doses), prizes, or vouchers that can be exchanged for goods or services. Despite the strong empirical support for CM, our research suggests that concerns relating to its cost and safety (e.g., potential for harm caused by rewards undermining intrinsic motivation or being sold to purchase drugs) have hindered its transfer to real-world practice. The exclusive use of non-cash CM likely stems from the untested assumption that clients will use cash incentives to buy drugs or engage in other high-risk behaviors. This assumption is problematic for two reasons. First, the use of non-cash incentives may add substantial costs and complexity to CM protocols. Second, the use of non-cash incentives may reduce the efficacy of CM interventions, as research suggests that cash may be a more effective reinforcer than vouchers. This study examines both practical and ethical issues relating to cash-based CM procedures. This study consists of three phases; a main experiment, a "Cash Bowl" pilot, and a "Thinning" Pilot.
