Introduction
Self-confidence and sport confidence (SC) have been viewed as some of the most important factors that influence the sport performance. Many studies had shown that athletes with high sport confidence would possess better concentration, game strategies, healthy emotions, control of tempos, and performance (Chi, 1996; Gould, 1981; Mahoney, Gabriel & Perkin, 1987). Therefore, the relationship between sport confidence and performance should be a critical topic for sport psychologists to investigate.
