An Ecological Study of the Moderating Effect of Self-Efficacy on the Relationship between Personality and Biomechanical Consistency
Résumé
Self-efficacy is a widely called upon theory in the domain of sport sciences. However, much debate surrounds the way precepts of self-efficacy are measured (Bandura, 2006) and how they relate to performance (Moritz, Feltz, Fahrbach & Mack, 2001). Following Bandura's (2006) guidelines, the present paper aims to make sense of the above criticism by testing the strength of a purpose-built self-efficacy questionnaire in predicting subjects' biomechanical performance in a dart-throwing task, against that of trait narcissism, as measured by the NPI (Raskin & Hall, 1979). Ten expert darts players took part in the present study. Data was collected using questionnaires and a 3D motion capture system during an international darts meet. Results suggest that increased levels of trait narcissism will lead to less biomechanically measurable effort into performance, and that this relationship is moderated by participants' precepts of self-efficacy. This moderation model posits that performance-related effort will increase as levels narcissism increase, provided that the subject perceives himself to be less competent in the task at-hand.
