This study aimed to explore the relationship among personality traits, psychological factors, such as self-efficacy, mental energy, and perfectionism, and the ability of college athletes to perform successfully as measured by their level of competition. Fifty-six NCAA Division I college athletes between 18 and 23 years old participated in the study. The questionnaire for this study included four different scales that measured personality traits, energy, individual and social self-efficacy, self-regulation, intrinsic motivation, and perfectionism levels of participants. The study examined the extent to which these psychological variables are important in determining the performance of college athletes. Results from the study revealed that athletes who played individual sports scored higher in openness compared to team sport athletes. Limitations and future research directions were discussed
