Abstract 

Contingency management interventions provide reinforcement for abstaining from drugs and withhold reinforcement when drug use is detected. Previous work demonstrates that the reinforcement schedule with which reinforcement is delivered modulates the efficacy of the intervention. This pilot study explores the effects of reinforcement in methamphetamine-dependent individuals. Results suggest that schedules incorporating an increasing magnitude of reinforcement for consecutive abstinences with a reset in reinforcer magnitude for a positive drug test produce superior results.
