This study examined internal (personal) and external (situational) factors that previous research found affected perceptions of physical aggression and associated reporting behaviors among student-athletes. Results of this study suggested certain factors significantly impacted a student-athlete's decision to report and who received that report. Internal factors included age, gender and race. External factors included the type of sport an athlete participates in, bystander group characteristics and relationship strength of people involved (perpetrators, victims and bystanders). This study found all factors affected reporting behaviors except for age. However, only sport type and existing relationships affected who received the report of physical aggression. Although completely eliminating physically aggressive behaviors among student-athletes is an unrealistic goal, the findings of this study contribute to decreasing its occurrence by increasing the levels of violence reporting. This study also provided guidance for future intervention strategies. [The dissertation citations contained here are published with the permission of ProQuest LLC.
