• Conditions: Automobile Accident
• Interventions: Device: Do Not Disturb While Driving

• Registration Number: NCT05298267
• Lead Sponsor: University of Pennsylvania

Brief Summary

We propose to test a potential intervention to reduce distracted driving among high school students that could be used as part of future research trials and school campaigns. This intervention is designed to encourage use of a setting that silences incoming calls and messages while the person is driving.

Detailed Description

The purpose of this study is to test an intervention to reduce distracted driving among high school students. We're interested in learning the use of Do Not Disturb While Driving (DNDWD) by high school students. Participants will be recruited to participate into a 4-week study. Those that consent will download a driving app that will monitor their phone use while driving. Halfway through the monitoring period, we will ask participants to turn on DNDWD. Participants will also have the opportunity to enroll into an auto-reply message contest for best message. Once the 4- week monitoring period is complete participants will complete and exit survey

Arm && Interventions

Group	Intervention	Description
Monitoring phase	Do Not Disturb While Driving	Participants will be monitored for 4 weeks. Halfway through the monitoring period, participants will be asked to turn on DNDWD.

Primary Outcome Measures

Name	Time	Method
Change in self-reported DNDWD	For the duration of the study; 4 weeks	Change is reported use. Dichotomy of use or non-use pre and post intervention

Secondary Outcome Measures

Name	Time	Method
Seconds of speeding per hour of driving	For the duration of the study; 4 weeks	. Speeding events, defined as \>10 mph above the posted speed limit, are detected by the app.
Seconds of passive (hands-free) call use per hour of driving	For the duration of the study; 4 weeks	Use of DNDWD should also cut down on hands-free driving distraction.
Responses to open-ended questions in exit survey	For the duration of the study; 4 weeks	Participants will be asked the following two open-ended questions: 1) "Please tell us what you liked about participating in this study;" 2) "Please tell us what you didn't like about participating in this study and how we should improve the experience in the future." These qualitative responses will be coded for content related to intervention acceptability and emerging themes will be identified.
Seconds of active (handheld) non-call use per hour of driving	For the duration of the study; 4 weeks	We will analyze the components of the secondary outcome separately.
Seconds of active (handheld) phone use per hour of driving	For the duration of the study; 4 weeks	This is a composite outcome that measures the proportion of total trip time in which the driver is engaged in handheld phone call use or non-call handheld use (e.g. texting, swiping, and typing), as measured by the Way to Drive app. Several studies (e.g. Klauer, NEJM, 2014) have demonstrated the association between handheld phone use (e.g., reaching for phone, typing, swiping, dialing) and increased crash risk. This outcome is also known as the active phone use percentage. Passive phone use (e.g. phone is streaming GPS navigation directions or music without any typing, swiping, and handheld holding of the phone) is not included in this outcome. Trips are only counted if the app predicts the user was a driver for the trip based on the phone sensor data and the user does not correct the app; or, if the user corrects the app and indicates they were driving.
Seconds of passive (hands-free) non-call use per hour of driving.	For the duration of the study; 4 weeks	Use of DNDWD should also cut down on hands-free driving distraction.
Seconds of active (handheld) call use per hour of driving.	For the duration of the study; 4 weeks	We will analyze the components of the secondary outcome separately.
Hard braking events per 100 miles.	For the duration of the study; 4 weeks	Hard braking events are detected by the app.
Fast acceleration events per 100 miles.	For the duration of the study; 4 weeks	Fast acceleration events are detected by the app.; Acceptability of interventions will be measured using a mixed-methods approach:
Net promoter score	For the duration of the study; 4 weeks	In the exit survey, participants will be asked "How likely is it that you would recommend this program to a friend or colleague?" on a 0 to 10 scale.
