简要总结
The study team is proposing to conduct a randomized controlled trial to determine the effectiveness of behavioral and financial incentives on phone use while driving and seat belt adherence. Each arm will receive a support text if their app is not collecting data. The behavioral engagement intervention includes persuasive education, mental contrasting with implementation intentions, customized habit tips, weekly feedback about participants' streaks, and encouraging SMS texts. The two financial incentive interventions add on weekly raffles or shared pots for participants with perfect streaks.

干预措施: Weekly SMS Support text (Behavioral)
Behavioral Engagement
Participants will receive a multicomponent safer driving intervention based on behavioral science. This will include persuasive education, WOOP (mental contrasting with implementation intentions) and customized habit tips.
