Summary
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.
