NCT01624597

Brief Summary

This randomized controlled trial will evaluate an intervention that provides parents with objective feedback about their teen's driving as well as strategies to improve communication with their teen about driving. We will recruit 180 newly-licensed teen drivers and a parent or guardian. Our main hypotheses are that: parent-teen dyads who receive feedback will have reduced driving errors and increased safety behaviors than dyads with no feedback; and, parent-teen dyads who receive instruction on communication techniques will have improved quality and quantity of communication about driving than dyads not learning these techniques.

Outcome Measures

Primary Outcomes (1)

  • Driving errors by newly licensed teen drivers

    An in-vehicle video system will be used to measure driving errors made by newly licensed teen drivers

    6 months after licensure

Secondary Outcomes (2)

  • Safety behaviors of newly licensed teen drivers

    6 months post-licensure

  • Parent communication

    6 months

Study Arms (3)

Usual Care

NO INTERVENTION

Participants will have a passive in-vehicle video device installed in their car to measure driving errors and safety behaviors.

In-vehicle video feedback

EXPERIMENTAL

Participants will receive feedback from an in-vehicle video system. A light on the system will blink when a driving event has been recorded. Parents will receive a weekly report card of driving errors.

Behavioral: In-vehicle video feedbackBehavioral: Parent communication
