Symptom Dimensions of Disruptive Behavior Disorders in Adolescent Drivers

Abstract

Objective: Adolescents with disruptive behavior disorder, including ADHD, are more likely to engage in risky driving practices and, consequently, are more likely to be involved in a motor vehicle crash (MVC) than their non-ADHD peers. It is unclear whether symptoms of inattention, hyperactivity/impulsivity, or oppositional defiant disorder (ODD) increase risk of poor driving outcomes. Method: A total of 41 participants (16-19 years old) reported their ADHD and ODD symptoms and risky driving practices (errors and violations). History of citations and MVCs were acquired from state records. Relative predictive utility of symptom dimensions was assessed using multiple regressions. Results:Inattention solely predicted driving variables of interest: Greater levels of inattention were predictive of more citations, MVCs, and self-reported errors and violations. Conclusion: Findings suggest that symptoms of inattention play a primary role in driving-related problems among adolescents. Implications for future research and practice are discussed. © 2012 SAGE Publications.
