What You Need to Know Before You Apply

What is the purpose of this trial?

Using a randomized controlled trial (RCT), the goal of this study is to evaluate the ability of evidence based behavioral treatment (contingency management: CM) to significantly decrease alcohol use and cigarette smoking among treatment-seeking smokers with an alcohol use disorder (AUD) who have initiated pharmacotherapy (varenicline; VC) for smoking cessation.

Will I have to stop taking my current medications?

The trial requires that you are not currently receiving any medication for alcohol or smoking. If you are on such medications, you would need to stop them to participate.

Is contingency management safe for treating substance use disorders?

Research on contingency management, which uses rewards to encourage positive behavior, suggests it is generally safe for treating substance use disorders. Studies have shown it can be effective without causing harm, even when using cash-based incentives, although more research is needed to confirm these findings in larger groups. ^{1 2 3 4 5}

How does the Contingency Management treatment for alcoholism and tobacco use disorder differ from other treatments?

Contingency Management is unique because it uses tangible rewards, like prizes, to encourage abstinence from alcohol and tobacco, making it different from other treatments that may not use incentives. This approach has been shown to improve treatment retention and promote longer periods of abstinence by providing immediate, positive reinforcement for desired behaviors. ^{4 6 7 8 9}

What data supports the effectiveness of the treatment Contingency Management, Motivational Incentives, Prize Method, Carrot and Stick Method for alcoholism and tobacco use disorder?

Research shows that using prize-based contingency management (a system of rewards) can help people quit smoking and stay off drugs like cocaine and heroin. In one study, alcohol-dependent individuals who had the chance to win prizes were more likely to stay in treatment compared to those who did not have this incentive. ^{3 4 6 7 10}

I've had 4+ (women)/5+ (men) drinks at once, 4 times in the last month.

Attended at least 4 of 6 possible visits during the induction period

Exclusion Criteria

No suicide attempt in the last 20 years

Any other medical (discernable by initial blood tests) or psychiatric condition that Drs. Layton or Rodin determine would compromise safe participation

What Are the Treatments Tested in This Trial?

Interventions

• Contingency Management

Trial Overview The study tests if contingency management (CM), a behavioral treatment, can reduce alcohol use and cigarette smoking among those starting varenicline (VC) for quitting smoking. Participants are randomly assigned to either CM or a non-contingent control group to compare outcomes.

How Is the Trial Designed?

Group I: (CM+TAU) Contingency Management + Treatment as Usual Experimental Treatment 1 Intervention

Varenicline (VC) will be supplied in .5 mg tablets once per week during the active treatment period. During the first week of treatment (Week 3) participants will be instructed to take .5 mg once per day for days 1-3, and 0.5 mg twice per day for days 4-7. The investigators will maintain a target dose of 1mg twice per day for the remaining active treatment period. Additionally, participants will also receive Take Control counseling via video. Participants in CM+TAU will receive reinforcement for submitting urine samples that test negative for recent alcohol use.

Group II: (NC+TAU) No Contingency + Treatment as Usual Active Control 1 Intervention

Varenicline (VC) will be supplied in .5 mg tablets once per week during the active treatment period. During the first week of treatment (Week 3) participants will be instructed to take .5 mg once per day for days 1-3, and 0.5 mg twice per day for days 4-7. The investigators will maintain a target dose of 1mg twice per day for the remaining active treatment period. Additionally, participants will also receive Take Control counseling via video. NC+TAU will receive reinforcement for submitting any urine sample, regardless of test results.

Published Research Related to This Trial

In a study involving 81 nicotine-dependent smokers, the addition of prize-based contingency management (CM) to standard care significantly reduced smoking during treatment compared to standard care alone.

However, these reductions in smoking did not persist after the treatment ended, indicating that while prize CM can be effective in the short term, it may not lead to long-term cessation.

In a study involving 142 outpatients with cocaine or heroin dependence, both voucher and prize-based contingency management (CM) interventions led to longer treatment retention and greater durations of confirmed abstinence compared to standard treatment.

While there were no significant differences in abstinence rates at 6- and 9-month follow-ups, the duration of abstinence achieved during treatment was the strongest predictor of continued abstinence after treatment ended.

In a study involving 74 cocaine-dependent methadone outpatients over 12 weeks, both voucher and prize-based contingency management (CM) interventions led to longer durations of abstinence compared to standard treatment.

The study found no significant differences in outcomes between the voucher and prize systems, indicating that both methods are effective in promoting abstinence during treatment, which is linked to better long-term recovery outcomes.

A survey of 214 substance use treatment providers revealed that while many clinics are using reward programs, they often do not follow effective practices recommended by research, such as providing higher reward amounts or immediate reinforcement.

Providers with more extensive training in contingency management (CM) were more likely to implement effective strategies, suggesting that better training could improve the quality of reward-based interventions in real-world settings.

In a study of 42 alcohol-dependent veterans, those who received contingency management (CM) alongside standard treatment had a much higher retention rate in treatment (84%) compared to those receiving only standard treatment (22%).

By the end of the 8-week treatment period, 69% of CM participants remained abstinent from alcohol, while 61% of those in standard treatment had relapsed, indicating that CM is an effective strategy for promoting abstinence in alcohol treatment.

Incentive and contingency management strategies have shown effectiveness in modifying smoking behavior, particularly in controlled settings, suggesting they can be beneficial for smoking cessation efforts.

Quit-and-win programs, which use incentives to encourage quitting, attract many participants and have produced modest quit rates, although the quality of evaluations varies and more rigorous studies are needed to confirm their effectiveness.

In a study involving 34 individuals with Cocaine Use Disorder, larger fixed incentives for providing negative urine samples led to faster and more effective abstinence compared to smaller incentives.

The type of incentive structure (escalating and resetting vs. fixed) did not significantly impact the overall effectiveness, suggesting that the magnitude of the incentive is more crucial for promoting abstinence.

In a 16-week study involving 12 cocaine-dependent methadone patients, cash-based incentives of $50 and $100 significantly increased short-term cocaine abstinence compared to a control condition with no incentives.

The study found that cash-based incentives did not lead to increased cocaine use after receiving the incentives, suggesting they are a safe option for improving treatment outcomes in substance abuse interventions.

A portable contingency management (CM) system using cellphones and breathalyzers was tested with 30 adults, showing that 88.6% of breath alcohol concentration (BrAC) tests were submitted on time, indicating high feasibility for this method.

Participants receiving CM had a higher percentage of negative BrAC results and longer durations of abstinence, along with reduced drinking frequency and related problems, demonstrating the initial efficacy of this approach in addressing alcohol use issues.

A study involving 120 cocaine-abusing outpatients showed that a low-cost prize reinforcement contingency management (CM) intervention significantly increased abstinence rates, especially in patients receiving up to $240 in potential rewards compared to standard treatment.

Patients who started treatment with positive urine tests responded best to the CM intervention, indicating that the effectiveness of prize reinforcement may depend on the severity of the patient's condition.
