Clinical Trial Summary

The purpose of this research study is to determine if a new smartphone application helps to decrease distracted driving, and to learn about parent and teen perspectives about the application


Description:

This 3-group randomized controlled trial aims to (1) evaluate the frequency of smartphone use among young drivers and their parents/caregivers while driving; and (2) determine if the LifeSaver mobile app reduces the rate of smartphone use while driving. Eligible participants will be licensed teenage drivers between the ages of 16 and 18 years, and a parent/caregiver. The app will be downloaded and installed on both parent/caregivers' and teens' phones to monitor phone use while in a vehicle for 8 weeks.

Intervention

Device:
Background Mode
The LifeSaver app tracks the date, time, and global positioning system (GPS) location of each trip that the participant takes in a moving vehicle, along with a list of apps used during the trip, but does not contain any anti-distracted driving features.
Manual Mode
In addition to the features in the Background Mode, the LifeSaver app locks the participants' phone while they are in a moving vehicle unless they actively press an "Emergency Unlock" or "Passenger Unlock" button.
Auto-Detect Mode
In addition to the features in Manual Mode, the LifeSaver app's "Passenger Unlock" feature can only be used if the app, via the smartphone's camera, confirms that the participant is not the driver of the vehicle.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in frequency of smartphone use while driving Frequency of smartphone use is recorded by the LifeSaver app among the three app modes. Within-driver smartphone use over the 8-week study period is compared as the app modes change. Week 2, 4, 6, and post-intervention at Week 8
Secondary Change in frequency of self-reported smartphone use while driving The change in self-reported smartphone use while driving will be assessed using the same within-driver and between-driver comparisons as the primary outcome measure. Self-reported smartphone use is collected through 10 items on a participant survey that is completed at enrollment, Weeks 2, 4, 6 and post-intervention at Week 8. Participants report how many days during the previous 2 weeks (0-14) that they drove, and talked on a hands-held smartphone, talked on a hands-free smartphone, sent a text, and read a text while driving. Participants also report how many times per day (free text, any number greater than or equal to 0) that they drove, and talked on a hands-held smartphone, talked on a hands-free smartphone, sent a text, and read a text while driving. There is no overall self-reported smartphone use score for these survey items. Weeks 2, 4, 6, and Post-Intervention at Week 8
Secondary Participant acceptability of the smartphone App: survey Participant assessment of accessibility will be collected, and Manual Mode and Auto-Detect Mode of the LifeSaver app will be compared. Participants complete a survey at Week 8, post-intervention. 8 items in the survey ask participants about accessibility of the app through Likert scales (range from Not at all to Extremely). 3 items in the survey ask participants about accessibility of the app through open-ended questions, where participants are able to enter free text. There is no overall score for these survey items. Post-Intervention at Week 8
Secondary Participant usability of the smartphone app: survey Participant assessment of usability will be collected, and Manual Mode and Auto-Detect Mode of the LifeSaver app will be compared. Participants complete a survey at Week 8, post-intervention. 8 items in the survey ask participants about usability of the app through Likert scales (range from Not at all to Extremely). 3 items in the survey ask participants about usability of the app through open-ended questions, where participants are able to enter free text. There is no overall score for these survey items. Post-Intervention at Week 8
