The purpose of this experiment was to examine an athlete’s personality and whether their personality had an effect on them tearing their ACLs during their collegiate career. Participant’s sex and the sport they participated in at SOU were additional factors examined. Male and female athletes (N = 69) completed two questionnaires, one their personality using the Ten-Item Personality Inventory (TIPI), the other on reporting their ACL health and history. A reported 11 athletes tore their ACL (7 male, 4 female). Statistical analyses yielded no support for the hypothesis, discovering that being more extroverted and agreeable did not factor into whether or not the athlete had torn their ACL. However, statistical analyses yielded that women tended to be more extroverted than men, X² (2,68) = 6.722, p = .035. Also, against previous literature this study found that men tore their ACLs more than women, X² (1, 69) = 4.556, p = .033.
