Cost Effectiveness of Combined Contingency Management and Cognitive Behavioral Therapy for Alcohol Use Disorder
Study Details
Study Description
Brief Summary
Alcohol contributes to 88,000 deaths and costs an estimated $223 billion annually in the United States. Alcohol use disorder (AUD) is highly prevalent in veterans. The positive public health impact of reducing heavy drinking among veterans with AUD would prevent significant medical morbidity and mortality. Contingency management (CM) is an intensive behavioral therapy that provides incentives to individuals for reducing substance use. Monitoring alcohol abstinence usually requires daily monitoring. Because of this difficulty, CM approaches for treatment of AUD are not currently available to people with AUD. Our group has developed a mobile smart-phone application that allows patients to video themselves using an alcohol breath monitor and transmit the encrypted data to a secure server. This innovation has made the use of CM for outpatient AUD treatment feasible. The aim of the current study is to evaluate the effectiveness and cost effectiveness of CM as an add-on to cognitive behavioral therapy for AUD. The trial will also explore the potential usefulness of a long-term abstinence incentive ontreatment utilization and alcohol outcomes. Proposed is a trial in which 140 veterans with AUD will be randomized to receive either CM as an add-on to evidence-based CBT or CBT alone. Veterans will also be randomized to one of two long-term incentive conditions (i.e., receipt of a monetary incentive for abstinence/low-risk drinking at 6- months vs. no incentive). This project aims to advance AUD treatment by 1) testing the effectiveness of a mobile health approach that makes CM for AUD feasible, and 2) providing highly needed cost-effectiveness data on the use of behavioral incentives as an adjunct to CBT for the treatment of AUD. These aims are designed to address two significant barriers to the implementation of CM for AUD.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: CBT + mCM + incentive Participants in this arm will receive 12 sessions of cognitive behavioral treatment, mobile contingency management for alcohol abstinence, and a monetary incentive for 30-day abstinence at the 6-month follow-up. |
Behavioral: Cognitive Behavioral Therapy (CBT)
Twelve in-person counseling sessions designed to assist participants with becoming abstinent from alcohol use (or reduce use).
Other Names:
Behavioral: Mobile Contingency Management (mCM)
Abstinence (measured by breath alcohol) will be intermittently reinforced. For each breath alcohol concentration reading that tests negative, a participant will earn a virtual scratch-off lottery ticket that contains 100 different values.
Other Names:
Behavioral: Long-term incentive
This incentive is $300 for self-reported and bioverified 30-day abstinence from heavy drinking at the follow-up scheduled for 6-months after the initial quit date
Other Names:

| Experimental: CBT + mCM + no incentive Participants in this arm will receive 12 sessions of cognitive behavioral treatment and mobile contingency management for alcohol abstinence. They will not receive monetary incentive for 30-day abstinence at the 6-month follow-up. |

Outcome Measures
Primary Outcome Measures
- Average number of heavy drinking days [6-month post quit visit]
At the 6-month follow-up visit, participants will self-report the number of heavy drinking (> 5 drinks in day for men, > 4 drinks in a day for women) days they have had in the past thirty days.
Secondary Outcome Measures
- Average number of heavy drinking days [12-month post quit visit]
At the 12-month follow-up visit, participants will self-report the number of heavy drinking (> 5 drinks in day for men, > 4 drinks in a day for women) days in the past thirty days.
- Average number of binge drinking days [6-month post quit visit]
Participants will self-report the number of binge drinking (heavy drinking within a 2-hour period) days in the past thirty days.
- Average number of binge drinking days [12-month post quit visit]
Participants will self-report the number of binge drinking (heavy drinking within a 2-hour period) days in the past thirty days.
- Average number of drinking days [6-month post quit visit]
Participants will self-report the number of drinking days in the past thirty days.
- Average number of drinking days [12-month post quit visit]
Participants will self-report the number of drinking days in the past thirty days.
- Average number of drinks per drinking day [6-month post quit visit]
Participants will self-report the number of drinks on drinking days in the past 30 days.
- Average number of drinks per drinking day [12-month post quit visit]
Participants will self-report the number of drinks on drinking days in the past 30 days.
- Self-reported abstinence [6-month post quit visit]
Participants will self-report whether or not consumed any alcohol in the past 30 days.
- Self-reported abstinence [12-month post quit visit]
