Integrated Desktop and Simulator Training Reduced Crash Risk by 40%
CINCINNATI, Dec. 1, 2022 /PRNewswire/ -- Roadways can be a dangerous place for teen drivers, even more so for those diagnosed with attention-deficit/hyperactivity disorder (ADHD). This is because those with ADHD may have difficulty sustaining visual attention to the roadway, especially when distracted.
Now, an ADHD driver's training program developed at Cincinnati Children's reports success at reducing the frequency of long, distracted glances away from the road that often occur among youth with ADHD. Details were published December 1, 2022, in The New England Journal of Medicine.
"This training improves teen drivers' attention to the roadway, reduces crash risk and has the potential to save lives," says the study's principal investigator Jeff Epstein, PhD, a pediatric psychologist with the Division of Behavioral Medicine & Clinical Psychology at Cincinnati Children's.
Trainees Had Fewer Crashes/Near-Crashes
The study details outcomes of the FOCAL+ training program, which expands upon a desktop-based software platform called FOcused Concentration and Attention Learning (FOCAL). This study enrolled 152 teen drivers with ADHD, aged 16-19, and split them into two groups. The 76 teens assigned to FOCAL+ participated in multiple training sessions that involved wearing special eye-tracking monitors that detect "long" glances (2 seconds or more) away from the roadway during simulated driving.
When long glances away from the road occurred while drivers were performing secondary tasks in the simulator (i.e., searching for a visual symbol on the driving console), an alarm sounded. The 76 teen drivers assigned to the control group learned about driver safety and then, like the FOCAL+ drivers, participated in multiple training sessions while wearing an eye tracker which required them to perform the same secondary task as the FOCAL+ group. However, control drivers did not get alerts when they glanced away from the road for too long.
One month after training, teens in the control group had 28.05 long glances during driving simulation per drive compared to just 16.52 long glances for the FOCAL+ group?a 41% difference. Six months later, both groups slightly improved at avoiding long glances, but those who received the FOCAL+ training maintained a 42% edge. The study also reports that non-trained drivers were more variable than trained ones in their lane position?a driving indicator related to crash risk.
To measure the impact of the training on real-world driving, drivers in both groups had an eye-tracking camera attached to the windshield in their vehicles for a year. Teens who received FOCAL+ training had fewer long-glances and crashes and near crashes than the control group. In fact, there were 40% fewer crashes and near crashes among the FOCAL+ trained group (3.4%) than the control group (5.6%). None of the crashes involved fatalities.
These findings suggest teens with ADHD were able to generalize trained skills to real-life settings, Epstein says.
As a result of the success of the study, Cincinnati Children's is now offering this training to teens with ADHD. The five-session program will cost $250. Those interested in participating can call 513-636-8107 or visit the website to see if they or their teen qualify.
"Our ultimate goal is to make this training available to all teen drivers with ADHD," said Epstein. "The hope is to reduce teen driving injuries and fatalities and to provide parents with added comfort about their teen driver's safety."
Epstein notes that the sample of drivers in this study was limited to one geographic region and results may not be the same for drivers in other regions. But the results justify pursuing the programs further. The team plans to apply for grants to further investigate program efficacy.
The program founders also are studying ways to expand the program to other ADHD care providers, and perhaps other driving instruction providers.
The challenges ahead include scaling up the program and finding supporting sponsors.
