This commentary discusses the contributions of Drs. Antonia Abbey and Catherine Kaukinen to our understanding of risk factors for sexual and physical aggression among college students. Major contributions of their work are outlined. These include Abbey’s contributions to our understanding of trajectories of sexually aggressive behavior among college men, risk factors for engaging in sexual aggression among men, and the role of alcohol in sexual aggression. In addition, Kaukinen’s work has increased our understanding of the frequency of violence in college dating relationships as well as the association of violent relationships with health risk behaviors. Directions for future research are also outlined including a need to identify trajectories of violence risk as well as a need to understand the complex interrelationships among health risk behaviors and interpersonal violence. Finally, implications for practice and university policy are discussed, including a focus on the development of effective preventive strategies and proactive responses to violence.
