A new study from researchers at Children’s Hospital of Philadelphia (CHOP) and the University of Pennsylvania’s Annenberg Public Policy Center found that 18- to 24-year-olds who use cell phones while driving are more likely to engage in other risky driving behaviors associated with “acting-without-thinking,” a form of impulsivity. These findings suggest the importance of developing new strategies to prevent risky driving in young adults, especially those with impulsive personalities. The study was recently published in the International Journal of Environmental Research Public Health.
