Brief Summary

This study will test an intervention that was developed to improve parents\' driving instruction of teens\' hazard anticipation skills when teens are in the learner phase of licensure. Half of the parents in the study will receive the intervention and half will not. Investigators will then compare driving instructions given by parents in the two groups by recording driving sessions that parents and teens have together in that real world and by recording a drive that parents and teens will complete in a driving simulator. The driving simulator allows us to expose teens and parents to hazards they may encounter on the roadway without putting them in harm\'s way.

Conditions

Motor Vehicle Accident; Interaction, Parent-Offspring

Outcome Measures

Primary Outcomes (3)

• Parental instruction of teen's driving in vehicle

  Investigators will code whether the parent verbally identifies the hazard, whether instruction from parents is functional or higher order in nature, and if instruction precedes or follows the hazard event. Functional instruction refers to instruction that applies only to the current context (e.g., \"Slow down.\"). High-order instruction can be applied more generally to driving (e.g., \"When there are brake lights ahead, be ready to brake too.\") or why the hazard is dangerous by causally connecting dangerous features and their potential outcomes

  Measures of parental instruction of teen's driving in the simulator will take place approximately between weeks 2 and 4 weeks of study enrollment.

• Parental instruction of teen's driving in simulator

  For the simulator drive, investigators will code whether the parent verbally identifies the hazard, whether instruction from parents is functional or higher order in nature, and if instruction precedes or follows the hazard event. Functional instruction refers to instruction that applies only to the current context (e.g., \"Slow down.\"). High-order instruction can be applied more generally to driving (e.g., \"When there are brake lights ahead, be ready to brake too.\") or why the hazard is dangerous by causally connecting dangerous features and their potential outcomes

  Measures of parental instruction of teen's driving in the simulator will take place approximately 4 weeks after enrollment.

• Teens driving performance in simulator - lane position

  For the simulator driver investigators will also measure if parental instruction result in improved driving performance among teens. The investigators will specifically measure differences in lane position among the two groups in response to roadway hazards and parental instruction.

  Measures of teen's driving performance in the simulator will take place approximately 4 weeks after enrollment.

Secondary Outcomes (2)

• Teens driving performance - accelerator release

  Measures of teen's accelerator release in the simulator will take place approximately 4 weeks after enrollment.

• Teens driving performance in simulator - brake force

  Measures of teen's driving performance in the simulator will take place approximately 4 weeks after enrollment.

Study Arms (2)

Hazard Anticipation Program for Parents of Teen Drivers

EXPERIMENTAL

Parents and teens randomly assigned to this arm of the trial will engage in a web-based training that provides parents with guidance on how to train their teen to identify potential hazards on the roadway. Parents are also given an opportunity to practice these new skills with teens when watching videos unfold together. The program will take 4 hours to complete and can be done over a two-week period at the parent's convenience.

Behavioral: Hazard Anticipation Program for Parents of Teen Drivers

Control

NO INTERVENTION

The parents and teens in this arm of the study will not receive an intervention of any kind.

Interventions

Hazard Anticipation Program for Parents of Teen Drivers BEHAVIORAL

Parents and teens who receive the intervention will complete a web-based training that provides parents with guidance on how to teach their teen to identify potential hazards on the roadway. The program begins by providing background on teens' difficulty learning this skill and the motivational interviewing techniques that are being used in the course. Parents then engage with a series of hazard videos. For each hazard, parents watch the hazard unfold, provide an example of what they might say to their teen in that, and are provided with examples of how to coach their teen through the hazard before it becomes a critical event. Parents and teens then jointly watch 12 videos depicting hazards unfolding on the roadway. Teens are asked to identify the hazard without parental input by pressing a spacebar. Teens must also indicate what they believe was the key event that caused the hazard. Then parents and teens are given an opportunity to replay the video and discuss the hazard together.
