Abstract We designed a food intake assessment device to facilitate gathering objective data about food choices and the adequacy of the diets of children. The device consists of a card display of 40 foods and a pictorial representation of a day with which students indicate their typical food patterns. The back of each food card indicates the contribution that a serving of the food made to a food group. We conducted a field test with 532 third-grade to sixth-grade students from 12 schools in 6 states to determine validity, scoring accuracy, and usability with diverse groups. Overall, students selected foods that we considered typical of usual meal patterns in the United States, although total daily energy intake from the selected foods was somewhat lower than the RDAs for these age groups. Teacher-calculated scores agreed reasonably well with computer-calculated scores. This device that assesses food behavior rather than nutrition knowledge may be useful as part of the evaluation instrumentation for nutrition education programs in elementary schools.
