About

The "Safe Vehicle Engagement (SaVE)" trials are 3 parallel randomized clinical trials that aim to determine the impact of text messaging (SMS) vehicle safety interventions vs. weekly SMS vehicle safety self-monitoring alone on seat belt use, distracted driving and drink driving among young adults identified in the emergency department (ED) with risky vehicle behaviors.

Full description

The investigators propose to conduct 3 related randomized, controlled, parallel group, assessor-blind, superiority trials of 6-week text message interventions vs. SMS vehicle safety self-monitoring in young adult participants with risky vehicle behaviors. A total of 500 adult participants will be enrolled: 300 into Cohort 1 (seat belt); 100 into Cohort 2 (distracted driving); 100 into Cohort 3 (drink driving). Each SMS intervention will be designed to target a single risk behavior. The study is powered to show a difference of 15% in the percentage of subjects reporting seat belt use at week 8. Other cohort trials (i.e. distracted driving, drink driving) and outcomes will be exploratory.
