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 a 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 α = .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.
