Parent-based Intervention to Increase Safe Teen Driving

Not Applicable

Completed

• Conditions: Motor Vehicle Occupant Injury; Teenaged Driver
• Interventions: Behavioral: Teen driving intervention

• Registration Number: NCT01014923
• Lead Sponsor: University of Iowa

Brief Summary

We hypothesize that this intervention will increase the quality and quantity of parental interaction on safety driving with newly-licensed teen drivers. 250 parent/teen dyads will be individually randomized into intervention and control groups. The intervention group will receive a tailored, in-person intervention with a trained member of the research team, with follow-up intervention phone calls each month for the 3-month intervention. The control group will be a "usual care" group who will receive driving safety materials available to all new drivers and their parents. Parents and teens will be followed to see if intervention parents meet the intervention's driving goals and to see if the parent and teens report improved driving skills and behaviors in the intervention compared with the control group.

Detailed Description

Drivers in their first six months of licensure have the highest crash rates of all drivers, leading to high rates of injury for themselves, their passengers, and those they hit. Parents play a critical role in the driving experience of their children. Policy approaches, such as Graduated Driver's Licensing Systems, and educational programs that encourage parents to define driving rules and restrictions have shown some success in reducing teen risky driving. However, methods to increase parental involvement in teaching driving skills and encouraging safe driving behaviors have not been widely tested. Such interventions can augment existing GDL systems by increasing parental knowledge and involvement in learning to drive.

The long-range goal of this research is to develop a sustainable and generalizable intervention that will reduce crashes and related injuries among teen drivers by increasing safe driving practices. The investigators propose to conduct a randomized trial of an educational intervention for parents of newly licensed adolescent drivers to increase parental involvement in teaching driving skills and safe driving behavior. Seven schools in small towns in the state of Iowa have agreed to participate. These schools are all within 50 miles of Des Moines, Iowa's largest city, which will lead to driving exposure in rural and town environments.

Parents of newly-licensed teenaged drivers will be the primary subjects enrolled in this study, and parents only will participate in the intervention. Teen drivers will also be enrolled so that they can provide information about their driving attitudes and behaviors; their role will be limited to filling out surveys. The intervention will include a focus on teaching driving skills and behaviors and on effective communication strategies with teens. The intervention content includes specific driving goals that parents meet with their teen drivers that focus on skills and behavior. This project will be conducted in a rural population, so skills for driving on rural roads will be included. The delivery of the intervention will use motivational interviewing, a successful and age-appropriate health behavior communication technique that has shown great success in related health fields.

250 parent/teen dyads will be individually randomized into intervention and control groups. The intervention group will receive a tailored, in-person intervention with a trained member of the research team, with follow-up intervention phone calls each month for the 3-month intervention. The control group will be a "usual care" group who will receive driving safety materials available to all new drivers and their parents. Parents and teens will be followed to see if intervention parents meet the intervention's driving goals and to see if the parent and teens report improved driving skills and behaviors in the intervention compared with the control group.
