Despite the advocacy of a confidence-enhancing function of mental imagery, the relationship between confidence and imagery has received little attention from sport researchers. The primary purpose of the present study was to identify the specific image content of confident athletes. Fifty-seven elite competitive rollerskaters completed the Movement Imagery Questionnaire-Revised (MIQ-R), the Sport Imagery Questionnaire (SIQ), and the State Sport Confidence Inventory (SSCI). Results revealed that high sport-confident athletes used more mastery and arousal imagery, and had better kinesthetic and visual imagery ability than low sport-confident athletes did. A hierarchical multiple regression analysis revealed that mastery imagery accounted for the majority of variance in SSCI scores (20%). The results of this study suggest that when it comes to sport confidence, the imaged rehearsal of specific sport skills may not be as important as the imagery of sport-related mastery experiences and emotions.
