• Conditions: Motor Vehicle Accident; Interaction, Parent-Offspring
• Interventions: Behavioral: Hazard Anticipation Program for Parents of Teen Drivers

• Registration Number: NCT06611241
• Lead Sponsor: Elizabeth O'Neal

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.

Detailed Description

The project seeks to test an intervention designed to improve parents' communication about roadway hazards by comparing parent instruction and teen driving outcomes between dyads whose parents were assigned to the intervention vs. the control condition. Participants will be 100 parent-teen dyads. Half of the parent-teen dyads will receive the intervention and half will not. Parents who receive the intervention will complete web-based program developed to help parents instruct teens on how to identify hazards on the roadway and respond appropriately before they pose a crash risk. Parents in the intervention arm of the study will be given 2 weeks to complete the training. Parents in the control arm of the study will not receive training. After the delivery period, parents and teens will be given two additional weeks to apply the training in their everyday driving instruction. During this period, parents in both groups will complete a minimum of 5 drives with their teen that will be recorded. Investigators will then have teens and parents complete a drive in a driving simulator. Teens will drive and parents will instruct from the passenger seat, just like they would in the real world. The drive will have 12 hazards. Compared to parents in the control group, investigators believe that parents in the intervention group will exhibit improved communication about potential hazard detection with their teens. Similarly, the investigators believe that teens of parents who received the training will be better at anticipating and reacting to potential hazards on the roadway when driving independently compared to teens whose parents did not engage in the program.

Arm && Interventions

Group	Intervention	Description
Hazard Anticipation Program for Parents of Teen Drivers	Hazard Anticipation Program for Parents of Teen Drivers	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.

Primary Outcome Measures

Name	Time	Method
Parental instruction of teen's driving in vehicle	Measures of parental instruction of teen's driving in the simulator will take place approximately between weeks 2 and 4 weeks of study enrollment.	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
Parental instruction of teen's driving in simulator	Measures of parental instruction of teen's driving in the simulator will take place approximately 4 weeks after enrollment.	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
Teens driving performance in simulator - lane position	Measures of teen's driving performance in the simulator will take place approximately 4 weeks after enrollment.	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.

Secondary Outcome Measures

Name	Time	Method
Teens driving performance - accelerator release	Measures of teen's accelerator release in the simulator will take place approximately 4 weeks after enrollment.	For the simulator driver investigators will also measure if parental instruction result in improved driving performance among teens. Investigators will specifically measure differences in accelerator release among the two groups in response to roadway hazards and parental instruction.
Teens driving performance in simulator - brake force	Measures of teen's driving performance in the simulator will take place approximately 4 weeks after enrollment.	For the simulator driver investigators will also measure if parental instruction result in improved driving performance among teens. Investigators will specifically measure differences in lane position among the two groups in response to roadway hazards and parental instruction.
