目的：确定包含 10 项的调查问卷（食品标签素养应用营养知识调查问卷）的信度和效度。方法：参与者是接受 90 分钟校内营养计划的小学生。通过 Cronbach alpha 和组内相关系数 (ICC) 评估可靠性。通过 t 检验，使用营养质量的客观指标——总体营养质量指数 (ONQI)，比较问卷的食物选择，评估有效性。统计显着性设定为 0.05。 结果：499 名儿童参与，其中 51% 为女性，平均年龄为 8.6 (+/- 0.9) 岁。观察到 Cronbach α = 0.77 和 ICC = 0.68（给药之间）。与错误回答的 ONQI 得分相比，正确回答的 ONQI 得分显着更高（27.4 +/- 9.4 vs 16.2 +/- 9.4；P = .01）。 结论和启示：应用营养知识食品标签素养调查问卷被发现是可靠且有效的衡量接受营养侦探项目的儿童食品标签素养的指标。
Objective: To determine the reliability and validity of a 10-item questionnaire, the Food Label Literacy for Applied Nutrition Knowledge questionnaire.Methods: Participants were elementary school children exposed to a 90-minute school-based nutrition program. Reliability was assessed via Cronbach alpha and intraclass correlation coefficient (ICC). Validity was assessed comparing the questionnaire's food choices using an objective metric of nutrition quality, the Overall Nutritional Quality Index (ONQI), via t test. Statistical significance was set at .05.Results: Four hundred ninety-nine children participated, 51% were female, and the average age was 8.6 (+/- 0.9) years. Cronbach alpha = .77 and ICC = 0.68 ( between administrations) were observed. ONQI scores of correct responses were significantly higher when compared to the ONQI scores of incorrect responses (27.4 +/- 9.4 vs 16.2 +/- 9.4; P = .01).Conclusions and Implications: The Food Label Literacy for Applied Nutrition Knowledge questionnaire was found to be both reliable and a valid measure of food label literacy in children taught the Nutrition Detectives program.
