Abstract

The purposes of this study were to identify the relationships between the risk-taking behavior, response inhibition, and risky motorcycle riding behavior of commuter motorcyclists with different levels of impulsivity, and to examine how these behaviors contribute to motorcycle accidents. A total of 255 Chinese commuter motorcyclists were recruited for this study. Their levels of impulsivity were classified according to the Chinese Barratt Impulsiveness Scale version 11th. Their risk-taking behavior was assessed by the Balloon Analogue Risk Task and their response inhibition was assessed by the Chinese version of the Stroop test Victoria version. The Chinese Motorcycle Rider Driving Violation Scale was used to assess risky motorcycle riding behaviors. Results showed that impulsivity was associated with risk-taking behavior and risky motorcycle riding. Highly impulsive motorcyclists carry out more risk-taking behaviors and are less able to inhibit responses than those with low impulsivity. Motorcyclists with medium impulsivity (OR, 4.74; 95% CI, 1.91-11.39) and those with high impulsivity (OR, 4.91; 95% CI, 2.34-10.24) were about 5 times more likely to be actively involved in motorcycle accidents than those with low impulsivity. Postlicense motorcycle riding experience and risky motorcycle riding behavior were two significant predictors of motorcycle traffic accidents after controlling for other sociodemographic variables. These results can facilitate the development of interventions, including the training and testing of motorcyclists, public education, and mass media messages about traffic risk.
