THE VALIDITY AND RELIABILITY STUDY OF THE TURKISH VERSION OF THE NUTRITION FOR SPORT KNOWLEDGE QUESTIONNAIRE

Aim: Nutrition knowledge is important for having an adequate and balanced nutrition in athletes. Despite there are some studies about nutrition knowledge of athletes to the best of our knowledge we couldn’t identify any questionnaire that measure nutritional knowledge of athletes. In this study, the validity and reliability study of the Turkish version of the Nutrition for Sport Knowledge Questionnaire was conducted. Methods: Data were collected from 275 athletes. Statistical analysis of the data was done by statistical package program. The questionnaire s adaptation to the original scale was evaluated with “Explanatory Factor Analysis”. Kendall W analysis was used for content/scope validity, pearson correlation analysis was used for item total score analysis. The level of internal consistency (reliability) among the items of the NSKQ was determined by item-total correlations and Cronbach Alpha Internal Consistency Coefficients. Results and Discussion: As a result of evaluating the validity and reliability of the Turkish version of the questionnaire which has a high level of validity and reliability (α = 0.908), is suitable and recommended for the evaluation of nutritional knowledge of Turkish athletes.
