Filter by:Alcohol use and alcohol-related disorders are highly prevalent in soup kitchen users, and this population is overrepresented by minorities and disproportionately affected by alcohol-related morbidity and mortality. Contingency management is a behavioral intervention effective in reducing substance use, but few studies have evaluated the efficacy of contingency management in the context of soup kitchens or homeless programs. The investigators found that contingency management, using a twice weekly testing and reinforcement schedule, had benefits for decreasing drinking in individuals receiving services at a homeless shelter. This study will replicate and extend these earlier findings to a soup kitchen population using more sophisticated alcohol monitoring procedures to better assess the extent of drinking in this group and in response to a contingency management intervention reinforcing submission of negative breath samples. Specifically, 40 hazardous drinkers recruited from a soup kitchen will be randomly assigned to one of two conditions: alcohol monitoring or the same plus reinforcement for provision of daily negative breath alcohol samples. The interventions will be in effect for 3 weeks, and all participants will also wear transdermal continuous alcohol monitors during the intervention period. Objective and subjective indices of alcohol consumption will be evaluated and compared between and within the treatment conditions. This pilot project will provide information regarding the effect size of contingency management reinforcing negative breath samples in an important health disparities group, and results from this study will guide subsequent grant applications focusing on methods to decrease drinking in this underserved population.
Reinforcement interventions have pronounced effects on reducing cocaine use. This study will evaluate a novel approach in which reinforcement frequency varies by patient performance. To test efficacy, 280 patients with cocaine use disorder will be randomly assigned to: standard care, standard care plus traditional twice weekly reinforcement, or standard care plus adaptive variable interval reinforcement.
Contingency management (CM) is highly efficacious for reducing substance use, and recent data suggest that reinforcing attendance at treatment can significantly improve treatment outcomes. Importantly, CM interventions that reinforce attendance are more likely to be adopted clinically than those that reinforce abstinence. Having objective indicators of drinking outcomes, nevertheless, is critical for quantifying the benefits of attendance-based CM treatment in alcohol abusing populations. New technology is now available to gauge alcohol use in patients' natural environments. The Secure Continuous Remote Alcohol Monitor (SCRAMx®) continuously monitors alcohol consumption 24 hours a day. As such, it may be ideal for objective evaluation of alcohol consumption during treatment intervention studies, including those that involve CM. In this study, 114 patients participating in community based outpatient treatment programs for alcohol use disorders will wear SCRAMx for a 12-week period. They will be randomized to standard care or standard care plus CM, with reinforcement contingent upon attendance at treatment. The investigators will assess treatment attendance and alcohol use via SCRAMx and self reports. The investigators expect that patients randomized to the CM intervention will remain in treatment longer and show reductions in both SCRAMx assessed and self reported drinking days relative to those randomized to standard care.
Contingency management (CM) treatments are highly efficacious in improving outcomes of substance abusing patients. However, CM has rarely been applied to individuals with alcohol use disorders, primarily because of technological limitations in monitoring drinking. The Secure Continuous Remote Alcohol Monitor (SCRAMx®) is a new technology designed to continuously monitor alcohol consumption 24 hours a day for 7 days per week. The purpose of this study is to evaluate the efficacy of CM in reducing alcohol use using SCRAMx. In total, 120 alcohol abusing or dependent patients initiating outpatient treatment at community-based clinics will be randomly assigned to one of two conditions: standard care, or standard care plus CM with reinforcement based on results of SCRAMx readings. Compared with standard care, it is expected that CM will result in fewer drinking days and longer durations of continuous non-drinking days.
This study will evaluate the efficacy of an exercise-based contingency management (CM) intervention. A total of 120 substance abusing patients in intensive outpatient treatment will be randomly assigned to one of two conditions: (a) standard care plus CM for completing goal-related activities not related to exercising (e.g., improving work, family, or transportation issues), or (b) standard care plus CM for completing exercise-related activities. Compared to those receiving goal-related CM activity contracting, it is expected that those in the exercise CM condition will participate in more physical activities and develop greater strength and flexibility, decrease drug use, reduce HIV risk behaviors, lessen depressive symptoms, and improve health indices.
Rates of overweight and obesity are increasing, particularly among individuals aged 18 to 29. An estimated 25-35% of American college and university students are overweight or obese. Contingency Management (CM) is a behavioral intervention that provides tangible rewards for positive behaviors. CM has substantial evidence of efficacy in reducing smoking and drug use and increasing treatment retention and medication compliance. The current study will evaluate the efficacy of a 24-week CM intervention to promote weight loss in overweight and obese university students. Seventy participants with a body mass index (BMI) of 27.0-34.9 will be randomly assigned to one of two conditions: (a) LEARN, a manual guided behavioral weight loss program (Brownell, 2004), with weigh-ins and supportive counseling, or (b) LEARN with weigh-ins and supportive counseling plus CM. Participants in the CM condition will earn chances to win prizes each week in which they lose at least one pound. Once they lose 5% of baseline body weight, they will earn chances to win prizes for weight loss or weight maintenance. Additional chances can be earned by completing activities that promote weight loss. The primary outcomes will be absolute and proportional weight loss from pre- to post-treatment, as well as proportion of participants achieving clinically significant weight loss (>5% of baseline weight) and proportion moving into a lower risk BMI category. Secondary outcomes will include length of retention in the study, increase in physical activity level, and improvement in nutritional quality of diet. Effects of the CM intervention on psychiatric distress and self-efficacy and motivation to engage in activities that promote weight loss will also be assessed. We predict that participants in the CM condition will lose more weight than participants assigned to the LEARN program without CM, and that more CM participants will achieve clinically significant weight loss. We also predict that participants in the CM condition will remain in the program longer, show larger increases in physical activity, show greater improvements in diet quality, and have greater increases in levels of self-efficacy and motivation than comparison group participants. Mediators and moderators of CM outcomes will also be evaluated. If efficacious in promoting weight loss in a college population, CM could help to prevent or delay later development of obesity-related medical problems.
Although LAAM, a derivative of methadone, has been successfully used as an alternative to methadone maintenance in opioid addicts, its effect on concurrent opioid and cocaine abuse has not been ascertained. Thus, this study proposes to examine the clinical efficacy of low- and high-dose LAAM maintenance on opioid and cocaine use in opioid-dependent cocaine abusers. In addition, since contingency management procedures have demonstrated some success in decreasing cocaine use in cocaine-abusing individuals, this study also proposes to examine the clinical efficacy of the presence or absence of contingency management procedures targeting illicit drug use.
