Abstract :This study aims to assess the validity and reliability of the Short Sports Nutrition Knowledge Questionnaire for Athletes (NUKYA), which was developed to evaluate the nutrition knowledge levels of athletes, in the Turkish population. The study was conducted on 355 athletes registered in the faculties of sports sciences at universities. The study was conducted in three stages. In the first stage, the language verification of the NUKYA scale was carried out. The second stage involved the test-retest application of this scale to all participants. Finally, \"The Nutrition for Sport Knowledge Questionnaire (NSKQ)\" was applied to 103 athlete participants to determine its construct validity. The validity and reliability study of the scale was evaluated with the SPSS 29.0 package program. It was determined that there was a positive correlation between the total scores of the NSKQ and NUKYA questionnaires (r = 0.379, p < 0.01). The Cronbach α coefficient of the scale was calculated as 0.888 for the overall survey. Since the Cronbach α value of 59 items on the scale was below 0.888, no items were removed from the survey. When the test-retest reliability results of the scale were examined, a positive, moderate correlation was found for the total score (r = 0.599, p < 0.001). It seems that the NUKYA is a comprehensive measurement tool that includes 59 items and 4 sections. Based on its validity and reliability, it could be an effective way to assess the nutritional knowledge levels of Turkish athletes.
