Abstract :Objective: The aim of this research is to determine validity and reliability of Sports Nutrition Knowledge Questionnaire insert ignore into journalissuearticles values(SNKQ); for the Turkish athletes. Patients and Methods: A total of 210 participants insert ignore into journalissuearticles values(n = 125 elite athletes and n = 85 Nutrition and Dietetics Department senior students); aged 19-30 years were enrolled in the research. SNKQ was evaluated utilizing the psychometric criteria to determine the reliability of items, test-retest reliability and known groups validity, by significance test insert ignore into journalissuearticles values(Independent Samples t-Test); of the difference between the two groups. After two weeks, SNKQ was applied again to some participants insert ignore into journalissuearticles values(n = 42); with the purpose of assuring testretest reliability. Results: The Sports Nutrition Knowledge Questionnaire was detected as valid and reliable according to the high internal consistency value insert ignore into journalissuearticles values(Kuder Richardson-20 insert ignore into journalissuearticles values(KR-20); = 0.927); and high test-retest reliability intraclass correlation coefficient insert ignore into journalissuearticles values(ICC = 0.974);. The difference between SNKQ total scores of athletes insert ignore into journalissuearticles values(36.0 ± 8.1); and Nutrition and Dietetics Department students insert ignore into journalissuearticles values(59.1 ± 5.98); was statistically significant; thus, the known groups validity was obtained insert ignore into journalissuearticles values(p < 0.001);. Conclusion: The Sports Nutrition Knowledge Questionnaire is valid and reliable. It can be easily used to determine the nutrition knowledge level of the Turkish athletes.
