Risky driving behavior among individuals with Autism, ADHD, and typically developing persons

Area of Science:

• Neurodevelopmental disorders
• Driving safety research
• Behavioral psychology

Background:

• Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) frequently co-occur and can impact driving abilities.
• Driving difficulties affect independence and daily participation for individuals with ASD and ADHD.
• Limited research directly compares driving safety outcomes between ASD and ADHD populations.

Purpose of the Study:

• To compare self-reported driving behaviors in young adults with ASD, ADHD, and typical development (TD).
• To identify differences in driving violations, errors, and risky behaviors among the three groups.

Main Methods:

• Fifty-four participants (14 ASD, 20 ADHD, 20 TD; ages 16-30) were screened for ASD and ADHD symptoms.
• The Driving Behavior Questionnaire (DBQ) assessed self-reported driving violations, errors, and risky behaviors.
• Group comparisons were made using ANOVAs and linear regressions.

Main Results:

• Drivers with ADHD reported significantly more overall risky driving behaviors and errors than ASD and TD drivers.
• No significant differences in risky driving behaviors or errors were found between ASD and TD drivers.
• Self-reported ADHD symptoms correlated with increased risky driving and errors across all participants, irrespective of diagnosis.

Conclusions:

• Driving errors and risky behaviors appear more strongly associated with ADHD symptoms.
• Findings suggest a need for targeted interventions for individuals with ADHD, considering their higher reported driving risks.
• Future research should utilize objective measures like driving simulators or on-road tests to evaluate driving performance in ASD and ADHD populations.
