Actual (reported)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.

Actual (reported)Alcohol impaired driving behavior
Participants will provide self-reported driving behavior (yes/no driven a vehicle) after drinking alcohol during the AA portion. This assessment will be taken from their daily smartphone responses.
12 weeks
Alcohol impaired driving behavior (retrospective)
Participants will provide self-reported driving behavior (yes/no driven a vehicle) after drinking alcohol retrospectively during interview sessions. Participants will complete regular phone interview where their daily driving and drinking behavior will be assessed. The outcome measure of interest will be days when participants report driving (yes/no) after consuming alcohol.
12 weeks
Alcohol impaired driving intentions
Participants will provide self-reported intentions to drive after drinking alcohol (Would you drive now? Yes/no) from daily assessments during the AA portion of the project.
6 weeks
Perceived risk of driving
6 weeks
Participants will receive a"BAC Feedback/Warning" intervention based on their assessed BAC. Participants in this arm will have a warning presented on their smartphone when they provide a breath sample that indicated their BAC has reached a set limit. The cutpoint for this warning is not disclosed but is well below the legal limit for driving. Warning will notify them that their results indicate it is not safe for them to drive. In this condition, participants will start their 6 week AA portion of their participation immediately after their laboratory session, and will be followed for 6 weeks afterwards. Comparisons between the two experimental conditions will allow for inferences about the onset and offset of any effects of the "BAC Feedback/Warning" intervention.

Participants will receive the "No BAC Feedback/Warning" intervention. Participants in this condition will complete the laboratory and interview portions of the project. However the AA portion of the project will not contain warning about their BAC (No BAC Feedback/Warning) and will ask fewer questions regarding their AID decisions. The role of this condition is to provide a baseline comparison of AID behavior for the two active assessment conditions.
Participants will receive no information on their current intoxication and will be asked to report less information on their driving decisions.
