The concept of self-efficacy is defined as the self-belief of the individual about the capacity to organize and execute the required activities successfully to perform and is considered to be one of the most effective psychological structures that mediate success in sport. Due to the fact that different components are effective on performance, self-efficacy should be measured specifically to the sport branch. The aim of this study was to investigate the validity and reliability of the Turkish version of the Climbing Self-Efficacy Scale. The scale, which was translated into Turkish, was applied to 114 people who actively engaged in rock climbing in 2017. The item-total score correlation coefficients were analyzed, and Cronbach alpha internal consistency analysis was performed in the Turkish form of the scale. In addition, explanatory factor analysis (EFA) and confirmatory factor analysis (CFA) were applied to the construct validity of the scale. The reliability coefficient of the scale is .87, similar to the original form. In the study, a one-dimensional structure explaining 47.86 % of the total variance was found. Furthermore, when the fit indices are evaluated according to CFA results, it is seen that the structure is within the generally acceptable compliance limits. As a result, it could be seen that the Turkish form of Climbing Self-Efficacy Scale is reliable and valid, and it could be applied to Turkish rock climbers. The CSES could be used to measure self-efficacy in different sub-branches of rock climbing in future studies.
