Self-control seems to be the core element for achieving optimal competitive performance, and be of great importance to well-being and healthy development of humans. According to the literature, there exist some correlations between personality traits and self-control. The aim of this study was to shed some additional light on the relationship between the Big Five personality traits and self-control in boxers and investigate self-efficacy as a mediator between the two variables. Two hundred and ten boxers (age: M = 18.89, SD = 3.83; amount of boxing practice: M = 4.93 years, SD = 3.22; 76 males) of Chinese national athletes participated the study. Results showed a pronounced level of self-control. The higher the competitive level, the higher the level of self-control. There were significant correlations among the Big Five, self-control, and self-efficacy. Self-efficacy mediated the relationship between the Big Five personality traits and self-control.
