Plain English Summary

Background and study aims
Motor vehicle collisions (MCVs) are the leading cause of death among teens worldwide. Over 80% of fatal MVCs in North America involve some form of driver distraction. Current strategies that focus on reducing the number of MVCs involving teens only look at removing phones as external sources of distraction, but do not address the ability of teens to detect (visual scanning) and respond (adjustment to stimuli) to critical information on the road. Given teen’s wide adoption and embracement of technology, this study is investigating the efficacy of the DriveFocus Ipad app as an intervention (program) on the visual scanning of critical roadway information and adjustment to stimuli of teen novice drivers, assessed via a Drive Safety CDS-200 high fidelity driving simulator.

Who can participate?
Healthy teen volunteers between the ages of 16 and 19, with a valid G1 or G2 driving license, who are able to read and understand English, and that can come to the study location.

What does the study involve?
The study involves 9 sessions (1 hour long, once a week for 9 weeks). All participants take part in a baseline assessment (first session) which includes: a series of pencil and paper tests that looks at different visual, cognitive and motor skills, a 7 minute acclimation drive on the simulator, and a 15 minute test drive. On the following three sessions, participants practice 1 hour with the app, which requires them to go through a series of interactive videos and identify critical items on the road. A first post-test is conducted on week 5, which consist s of the acclimation and testing drives only, followed by three more intervention sessions. On week 9, all the tests of week 1 are completed again.

What are the possible benefits and risks of participating?
This research study presents no substantial risk to the volunteer. While driving the simulator, he/she may be prone to experiencing some discomfort. Please note that simulated driving performance does NOT have reporting or legal implications on a person’s ability to maintain their license and/or progress through the graduated licensing process. The possible benefits may be: to have the opportunity to practice driving skills in a safe way, via the driving simulator. Also, participants may gain awareness on critical errors they make when driving. If beneficial, the intervention may also help recognize critical information on the road. The possible benefits to society may be: to provide evidence for the efficacy of an intervention that can helps teen drivers improve their skills, and potentially be safer road users.

Where is the study run from?
i-Mobile Research Lab, Western University, London, ON, Canada

When is the study starting and how long is it expected to run for?

Driving distraction among healthy teen novice drivers


Given teen’s wide adoption and embracement of technology, this study is investigating the efficacy of the DriveFocus Ipad app as an intervention on the visual scanning of critical roadway information and adjustment to stimuli of teen novice drivers, assessed via a Drive Safety CDS-200 high fidelity driving simulator. Designed by an occupational therapist and certified driver rehabilitation specialist, the fidelity and usability-tested DriveFocus app provides a structured approach to learning to detect and respond to critical roadway information. All teens will participate in a 6 week intervention (1 hour sessions once a week). Participants will receive their schedule for intervention sessions, and will attend the sessions in groups of 6. During the session, each participant will receive an iPad with the installed app. The app includes “drives” in 3 tours (different cities). Each tour includes up to 6 drives (interactive videos of drives thorugh different cities) . During the tours participants must notice critical objects on the road and touch them on the screen as they identify them. These critical objects include brake lights, pedestrians, other cars entering from side streets, and traffic controls.The drives are ordered in complexity from easiest to most difficult. According to their performance, teens can “unlock” the next complexity level when they obtain a high score for the previous level. The duration of the drives ranges from three to five minutes. Thus, it takes approximately 24 minutes to complete a tour if scores are always high enough for the teen to unlock subsequent levels. Teens will navigate 1 tour in each 1 hour session (for a total of 6 sessions) allotting for adequate time to improve their scores and navigate through the different levels of difficulty of each tour.

Participant inclusion criteria

A teen will be included if he or she:
1. Has a parent or guardian to accompany them
2. Is >16 years old and < 19 years old
3. Has not had seizure in the previous year

Target number of participants


Participant exclusion criteria

A teen will be excluded if he or she:
1. Has been diagnosed by the family or treating physician with a severe psychiatric (e.g., psychoses) or physical condition (e.g., missing limbs) that would preclude full participation
2. Uses medications that would negatively impact mental or physical functioning due to side-effects (established per parent/ self-report)
3. Is pregnant per parent/self-report (no previous driving simulator studies have assessed the potential risks to pregnant teens); (4) does not have a visual acuity of at least 20/50 with both eyes open and examined together (Ministry of Transportation of Ontario (MTO) requirement), as per visual acuity assessment that will be conducted in the first assessment session
