Food literacy provides a framework for food-related knowledge, skills, and behaviors. The aim of this study was to develop a Tool for Food Literacy Assessment in Children (TFLAC), grades 4-5.
Development of the TFLAC consisted of 3 phases: (1) content validity using a 2-round modified Delphi panel (n = 16) and content validity ratios (CVR); (2) pilot-testing (n = 38); and (3) assessment of internal consistency and test-retest reliability (n = 706) using Cronbach α and intraclass correlation coefficients, respectively. Statistical significance was set at P < .05.
Round 1 (CVR = 0.40) and 2 (CVR = 0.70) Delphi panel feedback and the pilot test informed modifications to the TFLAC question format, wording, and difficulty. Food literacy domain-specific Cronbach α values were acceptable (range, .80-.98) except for cooking knowledge (.63), and intraclass correlation coefficients were 0.64-0.70 (P < .001).
The TFLAC meets basic psychometric standards and may serve as a foundation for nutrition education intervention design and evaluation. Further testing with a broader geographic audience may be warranted.
食品素养为与食品相关的知识、技能和行为提供了一个框架。本研究的目的是开发一种适用于4至5年级儿童的食品素养评估工具(TFLAC)。
TFLAC的开发包括三个阶段:(1)使用两轮改良德尔菲小组(n = 16)和内容效度比率(CVR)进行内容效度评估;(2)预测试(n = 38);(3)分别使用克朗巴哈α系数和组内相关系数评估内部一致性和重测信度(n = 706)。统计学显著性设定为P <.05。
第一轮(CVR = 0.40)和第二轮(CVR = 0.70)德尔菲小组的反馈以及预测试为TFLAC的问题格式、措辞和难度的修改提供了依据。除烹饪知识(.63)外,食品素养特定领域的克朗巴哈α值是可以接受的(范围为.80-.98),组内相关系数为0.64-0.70(P <.001)。
TFLAC符合基本的心理测量标准,可为营养教育干预设计和评估奠定基础。可能需要对更广泛的地理区域受众进行进一步测试。
