Background: Motorcycling is one of the main causes of injury, and motorcyclists are among the groups vulnerable to road traffic injuries. Attention Deficit Hyperactivity Disorder (ADHD) in adults is presumably one of the determinants of road traffic injuries and risky behaviors of the motorcyclists. Despite the few studies on the relationship between motorcycle injuries and adult ADHD, their association has not been considered using standardized instruments. This study aimed to analyze the relationship between adult ADHD and risky riding behavior of motorcyclists.
Methods: The community-based cross-sectional study was run on 340 motorcyclists in Bukan, during 2015 and 2016, using a cluster-random sampling in 7 areas of the city. Using the city map provided by Bukan’s Health Center, the city was divided into 14 clusters according to the areas covered by health centers. Then, 7 clusters (out of 14) were selected randomly. To achieve the anticipated sample size, the data was collected from these 7 clusters. In this study, the data collection instruments were: standard Motorcycle Rider Behavior Questionnaire, Conners' Adult ADHD Rating Scales questionnaire and a checklist designed by the researchers. Stata 13 was used to analyze the collected data. Pearson correlation coefficient and multivariate linear regression were performed to study the linear relationship between ADHD score and scores of Motorcycle Rider Behavior Questionnaire.
Results: All 340 participants were male and the mean age was 30.2 years (SD=9.1). 22.1% of the motorcyclists had a history of motorcycle crash. Bivariate analysis showed a significant association between risky riding behaviors and age, motorcycling records, and mean of riding hours per day (P-value<.05). Multivariate analysis confirmed the correlation between ADHD and risky riding behaviors in all subscales (A, B, D) (p<0.05).
Conclusions: Those with a high ADHD screening score are more likely to have risky riding behaviors.
