简要总结
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.
详细描述
Motor vehicle crashes are the leading cause of death for people aged 13-25 years in the US, and approximately 31% of all fatal crashes involved some alcohol use. Several peer-reviewed studies have found that ridesharing was associated with fewer alcohol-involved crashes and DUI arrests. Theories of behavioral economics provide a clear theoretical mechanism by which ridesharing will reduce alcohol-involved motor vehicle crashes compared to other private transportation. However, while ridesharing may be an effective intervention to reduce alcohol-involved crashes, it may simultaneously increase alcohol consumption. This study will assess the impacts of subsidized ridesharing on impaired driving, alcohol consumption, and mobility. Participants will be randomized to either receive a rideshare voucher or an online shopping voucher, and effects on alcohol impaired driving and alcohol consumption will be measured. A GPS sub-group will use a custom smartphone application for GPS tracking to measure mobility.

干预措施: ridesharing voucher (Behavioral)
Control
Participants will be asked to complete 3 surveys over 2 weeks to collect in information on their alcohol use and about themselves, and receive online shopping voucher.
干预措施: online shopping voucher (Behavioral)
结局指标
主要结局
Change in the alcohol impaired driving incidents
时间窗: Baseline, 1 week follow-up, 2 week follow-up
Participants will provide two self-reported measures of impaired driving by indicating whether they "drove after drinking any alcohol" (driving after drinking) and "drove after drinking too much alcohol to drive safely" (driving while intoxicated) for each day during the previous 7 days.
Number of Participants Involved in Alcohol Impaired Driving Incidents
时间窗: At 1 week follow-up from baseline
Participants will provide two self-reported measures of impaired driving by indicating whether they "drove after drinking any alcohol" (driving after drinking) and "drove after drinking too much alcohol to drive safely" (driving while intoxicated) for each day during the previous 7 days. Data is recorded at baseline and at 1 week follow-up.
次要结局
- Change in number of days in alcohol consumption(Baseline, 1 week follow-up, 2 week follow-up)
- Average frequency of trips to alcohol outlets(Day 3 to Day 17 of study)
- Average duration of trips to alcohol outlets(Day 3 to Day 17 of study)
- Change in The Drinker Inventory of Consequences Score(Baseline, 1 week follow-up, 2 week follow-up)
- Change in Number of Days in Alcohol Consumption(Baseline, 1 week follow-up)
- Average Number of Trips to Alcohol Outlets(Day 3 to Day 17 of study)
- Average Duration of Trips to Alcohol Outlets(Day 3 to Day 17 of study)
