Determine the validity and reliability of a trait measure of robustness of self-confidence in sport

Robustness of self- confidence beliefs (the ability to maintain confidence beliefs in the face of adversity) have been highlighted as an important characteristic that contributes to the make up of mentally tough athletes. The purpose of the present set of studies was to validity and reliability of a trait measure of robustness of self-confidence in sport. beginning, for Validity questionnaires of robustness of self- confidence in the sports competition, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used. Cronbach's alpha method to evaluate the internal consistency and coefficient reliability and test-retest (espearman and Pearson correlations coefficient formula) and split half methods to confirm stability of the questionnaire was used. Results showed that the Cronbach's alpha reliability coefficient of the questionnaire Robustness of self- confidence is 0/731 and In terms of reliability is acceptable. Results support that the trait measure of robustness of self-confidence can be used.
