Much of the research conducted at the Center for ADHD at Cincinnati Children’s examines the real life struggles that children and adolescents with ADHD commonly experience. One of the areas we have been exploring for the past several years has been the risks of driving.
According to statistics from the Centers for Disease Control and Prevention, six teens (aged 16–19 years old) die every day from motor vehicle accidents. Having an ADHD diagnosis adds to that risk. Indeed, drivers meeting diagnostic criteria for ADHD are 2.2 times more likely to have multiple collisions as drivers without ADHD.
While the connection between the ability to pay attention and driving safely is fairly obvious, we have strived to understand more about the specific aspects of ADHD behavior that cause driving risk, and what, if anything, can be done to reduce the risk.
Members of our research team collaborated with several other centers to publish a new study that examined driving in a large sample of 441 children who were recruited and diagnosed with ADHD when they were 7-9 years old and have been followed into adulthood. In addition, a comparable sample of 239 children without an ADHD diagnosis were also recruited and followed along the same time points.
Our findings were published Aug. 22, 2020, in The Journal of the American Academy of Child and Adolescent Psychiatry (JAACAP). This study is the latest information from the Multimodal Treatment Study of ADHD, one of the largest and longest-running studies of its kind.
Several interesting findings came out of this study.
Indeed, teens who were diagnosed with ADHD as children but who no longer met ADHD diagnostic criteria (i.e., DSM-5) had no greater risk of getting into a motor vehicle accident than teens without ADHD. These results highlight the need for better understanding ADHD-related driving risks and to develop interventions that will help teens with ADHD become safer drivers.
Towards this end, research conducted at the Center for ADHD has demonstrated that teens with ADHD are more likely to veer out of their lane of traffic, particularly when given the opportunity for distraction (e.g., cell phone use).
We’ve even identified what we believe to be the primarily problem for teen drivers with ADHD–during driving-related (e.g., checking rear-view mirror) and non-driving related (e.g., texting) tasks, they take their eyes off the forward roadway for extended periods of time.
In the context of an NIH-funded study, we are currently testing an intervention that we hope will help train drivers with ADHD to be safer drivers. We look forward to reporting on the results of that study in the coming year.
While research teams such as ours continue to develop driving interventions for teens, parents should know that there are some things they can do to improve their adolescent’s driving behavior:
