Excessive intake of oil, salt and sugar is closely associated with the prevalence of non-communicable chronic diseases (NCDs). Canteen staff's knowledge, attitude and practice (KAP) about oil, salt and sugar directly affect the content in dishes and the consumers' intake. However, no valid questionnaire is used to assess KAP among canteen staff about the "oil, salt and sugar". Therefore, the present study aimed to establish and validate a questionnaire to evaluate the KAP of canteen staff about the "oil, salt and sugar". This cross-sectional study was conducted among canteen staff randomly selected from three college canteens. Participants completed the questionnaire and retested it two weeks later. Internal and test-retest reliability were assessed using Cronbach's α and Pearson correlation coefficients, respectively. Validity was assessed using the exploratory factor analysis. 100 participants finished the questionnaire, of which 66% were females with a mean age of 40.3 ± 10.5 years. The Cronbach's α coefficients of the total questionnaire and Knowledge, Attitude and Practice dimensions were 0.822, 0.830, 0.752 and 0.700, respectively. The test-retest reliability coefficient was 0.968. In exploratory factor analysis, nine common factors were extracted, with 26 items, and the cumulative contribution rate was 70.9%. The questionnaire had a satisfactory property for measuring the KAP of the "oil, salt and sugar" among canteen staff in China.
过量摄入油、盐和糖与非传染性慢性病（NCDs）的流行密切相关。食堂工作人员对油、盐和糖的知识、态度和实践（KAP）直接影响菜肴的内容和消费者的摄入量。然而，目前还没有有效的问卷来评估食堂工作人员关于“油、盐和糖”的 KAP。因此，本研究旨在建立和验证一个评估食堂工作人员关于“油、盐和糖”的 KAP 的问卷。这项横断面研究在三所大学食堂随机抽取食堂工作人员进行。参与者完成问卷，并在两周后进行重测。内部和重测信度分别用 Cronbach's α 和 Pearson 相关系数评估。有效性通过探索性因素分析进行评估。共有 100 名参与者完成了问卷，其中 66%为女性，平均年龄为 40.3±10.5 岁。总问卷和知识、态度和实践维度的 Cronbach's α 系数分别为 0.822、0.830、0.752 和 0.700。重测信度系数为 0.968。在探索性因素分析中，提取了 9 个共同因素，包含 26 个项目，累积贡献率为 70.9%。该问卷在中国具有良好的测量食堂工作人员关于“油、盐和糖”的 KAP 的特性。
