Abstract

Given that athletes frequently encounter setbacks, injuries, and psychological pressures, the ability to sustain effort and interest over the long term is considered critical for success. However, despite the growing importance of grit in sports, research in Turkey has been limited by the absence of culturally adapted instruments. Developing a valid and reliable Turkish measure is therefore essential for advancing sport psychology research and providing practitioners with tools to better understand athlete resilience. This study aimed to adapt the Short Grit Scale into Turkish for use with athletes and to examine its psychometric properties. The concept of grit, defined as perseverance and passion for long-term goals, has become increasingly relevant in sports psychology, yet there has been a lack of valid and reliable instruments tailored for Turkish athletes. A total of 222 athletes (122 males, 100 females) representing diverse sports disciplines voluntarily participated in the study. The scale adaptation process included linguistic equivalence, item revision based on expert opinions, and evaluation through exploratory and confirmatory factor analyses. The two-factor structure (Consistency of Interest and Perseverance of Effort) showed acceptable model fit indices (CFA: χ²/df = 1.69, CFI = 0.967, RMSEA = 0.056). Reliability analysis indicated satisfactory internal consistency (Cronbach's α: .71 and .76). Measurement invariance across gender was confirmed at configural, metric, and scalar levels. Test-retest reliability over a 20-day interval was r = .89 (p < .001), supporting the scale’s temporal stability. The Turkish version of the Short Sport Grit Scale is a valid and reliable tool for assessing grit among athletes.
