Abstract
This study investigated the association between unplanned drinking, drinking context, and alcohol-impaired driving (AID) cognitions and behavior among young adults using ecological momentary assessment (EMA) over six weeks. Participants were recruited from a large Midwestern university and the surrounding community, with eligibility criteria including regular driving and alcohol consumption. The analyses focused on the impact of unplanned versus planned drinking episodes and on- versus off-premises drinking locations on perceptions of AID danger, willingness to drive, and actual AID behavior, while accounting for alcohol consumption using a novel breath alcohol concentration (BrAC) Bluetooth device. Results indicated that unplanned drinking episodes were associated with lower perceived danger of AID, increased willingness to drive after drinking, and higher odds of engaging in AID, compared to planned drinking episodes. Similarly, drinking in on-premises locations (e.g., bars, restaurants) was associated with higher odds of AID behavior compared to off-premises drinking (e.g., at home, friends' houses), but not related to riskier AID cognitions. These findings highlight the need for targeted interventions and policies to reduce unplanned drinking and address the risks associated with on-premises alcohol consumption. Focusing on these risk factors can enhance efforts to prevent AID and improve public health outcomes among young adults.
