Evaluation of the Impact of App-based Feedback and Monetary Incentives on Teen Driver Safety (extension)

Teen drivers will participate in a six-month driving study that will yield comprehensive data on several driving performance measures. This data will provide the basis for driving feedback that will be provided to teens and their parents throughout the study. The study will consist of 4 experimental phases: Pre-feedback baseline (1 month), website feedback only (2 months), website feedback + monetary incentives (2 months), and post feedback baseline (1 month). Driving feedback will be available on a website that is accessible via mobile device. In addition to the provision of app-based feedback, participants will receive monetary incentives based on safe driving performance. The effectiveness of both the feedback app, and monetary incentives will be measured by examining teen driver safety (e.g., kinematic risky driving events, speeding, etc.). The usability and acceptability of this feedback will also be measured by analyzing the number of website logins and duration of time spent on the website. Participant intake and exit questionnaires will also be conducted to obtain qualitative data on user preferences and acceptability. Focus groups with both parents and teens regarding the feedback and monetary incentives will be conducted and the data analyzed.
