The aim of this study was to design and validate a questionnaire on quality and food education on catering company websites. For the validation of the questionnaire, its reliability, feasibility and content validity characteristics were determined. For content validity, a panel of experts was used and the overall and item-wise Content Validity Index (CVI) of the experts' responses was calculated. Reliability was determined by the inter-judge agreement method with the analysis of 30 websites using the intraclass correlation coefficient (ICC) and the Bland and Altman plot. Adequate content validity was verified by obtaining a very high CVI (above 0.80) in the analysis of the expert panel's responses and excellent inter-observer agreement with a very high global ICC (above 0.90) value in the determination of test-retest reliability. The questionnaire is a valid instrument for the evaluation of the quality of school catering websites and their content in food education, as it has good feasibility, high content validity and excellent reliability.
本研究旨在设计和验证一份关于餐饮公司网站的质量和食品教育的问卷。为了验证问卷的有效性，确定了其可靠性、可行性和内容有效性特征。为了进行内容有效性分析，使用了一组专家，计算了专家回答的整体和项目内容有效性指数（CVI）。可靠性通过使用组内相关系数（ICC）和 Bland 和 Altman 图分析 30 个网站的评委间一致性方法来确定。通过在专家小组的回应分析中获得非常高的 CVI（高于 0.80），以及在确定测试-重测可靠性时具有非常高的全局 ICC（高于 0.90）值，证明了充足的内容有效性。该问卷是评估学校餐饮网站及其食品教育内容质量的有效工具，因为它具有良好的可行性、高内容有效性和良好的可靠性。
