Driving in young adults with attention deficit hyperactivity disorder: knowledge, performance, adverse outcomes, and the role of executive functioning.
Past studies find that attention deficit hyperactivity disorder ( ADHD ) creates a higher risk for adverse driving outcomes . This study comprehensively evaluated driving in adults with ADHD by comparing 105 young adults with the disorder ( age 17 - 28 ) to 64 community control ( CC ) adults on five domains of driving ability and a battery of executive function tasks . The ADHD group self-reported significantly more traffic citations , particularly for speeding , vehicular crashes , and license suspensions than the CC group , with most of these differences corroborated in the official DMV records . Cognitively , the ADHD group was less attentive and made more errors during a visual reaction task under rule-reversed conditions than the CC group . The ADHD group also obtained lower sceres on a test of driving rules and decision-making but not on a simple driving simulator . Both self- and other-ratings showed the CC group employed safer routine driving habits than the ADHD group . Relationships between the cognitive and driving measures and the adverse outcomes were limited or absent , calling into question their use in screening ADHD adults for driving risks . Several executive functions also were significantly yet modestly related to accident frequency and total traffic violations after controlling for severity of ADHD . These results are consistent with earlier studies showing significant driving problems are associated with ADHD . This study found that these driving difficulties were not a function of comorbid oppositional defiant disorder , depression , anxiety , or frequency of alcohol or illegal drug use . Findings to date argue for the development of interventions to reduce driving risks among adults with ADHD
