Study Details

Study Description

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.

Arms and Interventions

Arm	Intervention/Treatment
No Intervention: (A) Non-contingent control Participants assigned to the control condition will be told to wear the pedometer daily and select a twice-weekly meeting schedule with research staff for 12 weeks (study weeks 4-15). On days randomly selected as meeting days, participants will be asked to bring in their pedometers. Participants who attend their scheduled meetings will receive a $5 gift card just for attending and bringing the pedometer, so long as it has registered steps walked in at least the past 4 days. They will be congratulated if they walked 10,000 steps or more on the prior 4 days, and encouraged to walk 10,000 steps or more per day on subsequent days.
Experimental: VIP CM Participants assigned to Increasing Variable Interval Prize (VIP) Reinforcement group will be scheduled for the same study visits as those in the Control group, but will also earn chances to win prizes if they have walked more than 10,000 steps in the past 4 days.	Behavioral: VIP CM Participants will receive progressively increasing CM for walking 10,000 steps per day over 4 days prior to visit as verified by the pedometer.
