5 Clinical Trials for Various Conditions
The purpose of this research study is to understand people's alcohol use in public places and their risks for harm. The overall goal of this study is to test the effects of subsidized ridesharing as an intervention to reduce self-reported alcohol-impaired driving, along with alcohol consumption and changes to mobility.
The current study will evaluate the efficacy of contingency management (i.e., reinforcement for avoiding heavy drinking) among adults arrested for drunk driving and who are at risk for ongoing heavy drinking.
According to the Centers for Disease Control and Prevention (CDC), "88,000 people die every year due to alcohol-related issues including homicide, sexual assault, intimate partner violence, and suicide". In the city of Dallas, violent crimes have decreased by roughly 4% in 2022 compared to 2021. Dallas Police Department (DPD) implemented changes in May 2021 to combat violent crimes.
This project combined laboratory and ambulatory assessment (AA) methods to test decision making associated with alcohol impaired driving (AID). Participants will complete a laboratory alcohol administration session followed by 6 weeks of mobile assessment. Data from drinking events will be examined to test how individuals make choices about driving or not after consuming alcohol.
This is a pilot study to set up a larger investigation examining predictors of the decision to drive after consuming alcohol. All participants will carry a study provided smartphone and breathalyzer device for the 2 week period of the study. The intervention is that participants are randomly assigned to one of 2 breathalyzer feedback conditions - one where they receive a warning that their results indicate they should not drive and one where they receive no feedback. The study is designed to provide information needed for a larger version with a similar protocol, but also to provide an initial test of project hypotheses as well.
