Extending Contingency Management's Benefits With Progressively Increasing Variable Interval Prize Reinforcement

Not Applicable

Completed

• Conditions: Exercise; Addictive Behaviors
• Interventions: Behavioral: VIP CM

• Registration Number: NCT01184040
• Lead Sponsor: UConn Health

Brief Summary

Contingency Management (CM) is highly effective in promoting recovery from substance use disorders, but benefits tend to attenuate over time when CM is discontinued. Identifying modifications of CM delivery that can extend its benefits is an important goal. The goal of this study is to evaluate the use of reinforcements to increase physical activity, specifically walking. The study provides a standard CM intervention to promote walking for three weeks. After three weeks, a progressively increasing variable interval schedule of reinforcement will be evaluated for increasing the durability of effects of the initial CM intervention. We hypothesize that Variable Interval Prize Contingency Management will result in greater adherence to a walking goal of 10,000 steps per day at Week 15 and Week 24 compared to the Control Condition.
