Although research evidence indicates that multitasking results in poorer learning and poorer performance, many students engage with text messaging, Facebook, internet searching, emailing, and instant messaging, while sitting in university classrooms. Research also suggests that multitasking may be related to risk behaviors. This study's purpose was to describe the multitasking behaviors occurring in university classrooms and to determine relationships between multitasking and risk behaviors. Surveys assessing multitasking, grades, and risk behaviors were completed by 774 students. Results show that the majority of students engage in classroom multitasking, which is significantly related to lower GPA and an increase in risk behaviors.
