Development of a Tool for Food Literacy Assessment in Children (TFLAC)

Objective: 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. Methods: 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 a and intraclass correlation coefficients, respectively. Statistical significance was set at P < .05. Results: 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 alpha values were acceptable (range, .80-.98) except for cooking knowledge (.63), and intraclass correlation coefficients were 0.64-0.70 (P < .001). Conclusions and Implications: 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.
