Brief Summary

Teens with Attention-Deficit/Hyperactivity Disorder (ADHD) have high rates of negative driving outcomes, including motor vehicle crashes, which may be caused by visual inattention (i.e., looking away from the roadway to perform secondary tasks). Two versions of a driving intervention that trains teens to reduce instances of looking away from the roadway will be tested in teens with ADHD.

Outcome Measures

Primary Outcomes (2)

  • Number of extended glances away from the roadway during simulated driving

    Participants will complete a simulated drive in a driving simulator with an integrated eye-tracking system. Participants will complete two 15-minute drives. During each drive, participants will engage in 14 secondary tasks. The secondary task consist of searching for streets on a GPS map for 20 seconds. Eye gaze will be sampled continuously. Eye gaze data will be summarized by calculating the number of extended (≥2 secs) glances away from the roadway during the 14 secondary task periods per drive. Descriptive estimates will reflect averages across the 2 drives. However, for analyses, estimates for each drive will be statistically modeled with a two-level drive variable.

EXPERIMENTAL

Enhanced FOcused Concentration and Attention Learning driver training using virtual reality

Behavioral: VR-FOCAL+

Wait-list Control

NO INTERVENTION

Teens will wait approximately 1 year to receive FOCAL+ training. In order to control for experience with the driving simulator across groups, teens in this group will attend 5 weekly sessions where they will experience five 5-minute drives in the driving simulator. During the drives, teens will be cued to a complete a visual search task which will require them to divert their gaze from the road. Teens in this group will not receive feedback regarding eye glances during these drives.

Interventions

FOCAL+BEHAVIORAL

Weekly for 5 weeks, teens complete a computer training program designed to train teens to limit the length of glances away from the roadway. During phase 1 of each training session, on a computer, the top portion of the screen plays a simulated video drive while the bottom half of the screen contains a map. Teens complete tasks that require switching between the 2 halves of the screen. While doing so, they receive feedback regarding how long they are looking away from the driving portion of the screen. During phase 2 of each training session, teens will complete five 5-minute simulated drives using a fixed-base driving simulator. During the drives, teens will be cued to a complete a visual search task which will require them to divert their gaze from the road. Eye tracking goggles will monitor eye glances and provide real time auditory feedback when a visual glance away from the roadway exceeds 2 secs.

FOCAL+ Training
VR-FOCAL+BEHAVIORAL

Weekly for 5 weeks, teens complete a training program designed to train teens to limit the length of glances away from the roadway. The training has two phases, each of which will be administered using immersive virtual reality. The first phase will have teens switch between the upper half of a virtual reality screen which will play a simulated video drive while the bottom half contains a map. Teens complete tasks that require switching between the 2 halves of the screen. While doing so, they receive feedback regarding how long they are looking away from the driving portion of the screen. During the second phase of each session, teens will complete five 5-minute simulated drives in a virtual reality environment where teens will be cued to a complete a visual search task which will require them to divert their gaze from the road. Eye tracking will monitor eye glances and provide real time auditory feedback when a visual glance away from the roadway exceeds 2 secs.

STUDY PROTOCOL, SAP, ICF
Time Frame
The study team will submit an initial batch of processed and cleaned data to the NICHD Data and Specimen Hub (DASH) after the first 50 participants have been enrolled in order to develop a pipeline for submitting study data to DASH. Along with these data, the investigators will develop and submit any data dictionaries and codebooks for these data. All remaining data will be submitted within 1 year of the last patient's last study visit, 4 months prior to any publication date, or 6 months before the end of the performance period, whichever is sooner.
Access Criteria
Clinical data will be shared with controlled access in NICHD Data and Specimen Hub (DASH) for general research use, as allowed by the participant's informed consents and the institutional certification. To access study data within DASH, users must submit a Data Request Checklist to DASH, sign the NICHD DASH Data Use Agreement, and submit proof of IRB approval.
