Abstract

Background: Sports nutrition knowledge is one of the essential needs of coaches. However, there is no standardized questionnaire in Persian to assess coaches' nutritional knowledge and information. Therefore, the purpose of this study is to evaluate the validity and reliability of Persian version of the Coach Sports Nutrition Questionnaire (CSNQ). Methods: CSNQ was translated-re-translated according to the WHO standard method, following Iranian culture and eating habits. The reliability of the questionnaire was assessed by test-retest method, correlation coefficient and internal reliability by Cronbach's alpha, and differential validity by independent t-test. 123 Iranian coaches completed the questionnaire. Results: The total internal reliability of the questionnaire assessed by Cronbach's alpha was 0.73. The intragroup correlation of the questionnaire, assessed by the test-retest method, was 0.71. Moreover, the comparison of the coaches with different levels of education was found to be significant (P < 0.001). Conclusion: The Persian version of the questionnaire regarding the coaches' nutrition sports knowledge has acceptable reliability and validity. It can help other studies and evaluate sports nutrition knowledge in Persian coaches.

波斯语版体育教练员营养问卷的信度和效度

背景:运动营养知识是教练员的基本需求之一。然而，没有波斯语的标准化问卷来评估教练的营养知识和信息。因此，本研究的目的是评估波斯语版教练运动营养问卷(CSNQ)的效度和信度。方法:按照世界卫生组织标准方法，遵循伊朗文化和饮食习惯，对《CSNQ》进行复译。问卷的信度采用重测法，相关系数和内部信度采用Cronbach’s alpha法，差异效度采用独立t检验。123名伊朗教练完成了问卷调查。结果:问卷经Cronbach's alpha评定的总内部信度为0.73。问卷的组内相关系数经重测法评估为0.71。此外，不同教育程度的教练员之间的比较发现具有显著性(P <0.001)。结论:波斯语版教练员营养运动知识问卷具有可接受的信度和效度。它可以帮助其他研究和评估波斯教练的运动营养知识。
