Abstract
The purpose of this study was to develop an instrument in measuring the level of confidence of individuals in their capabilities to perform sport tasks. A questionnaire with 22 items was made based on the theoretical framework. 567 individuals (301 males, 249 females) were chosen by stratified-available sampling and answered to these questions. The reliability of the questionnaire was 0.975 and 0.944 based on Cronbach’s alpha and split-half methods. The content validity of the questionnaire was confirmed by seven experts. CFA results showed that the questionnaire was impacted with one factor. The correlation between individuals’ test score and their efficiency and sport self-confidence scores was representative of the construct validity of the questionnaire (r=0.516 and r=0.738 respectively, p≤0.01). The correlation between the scores of the participants and their level of physical activity represented the criterion validity of the questionnaire (r=0.579, p≤0.01). Therefore, the questionnaire was of acceptable validity and reliability.
