Develop and validate a modifiable, paper-and-pencil questionnaire assessing FV consumption at school lunch. Five phase validation study, in which the questionnaire was iteratively modified. The setting was 23 public elementary schools from eight states in the U.S. (70% urban; 77% free/reduced price lunch eligible) participating in the National School Lunch Program. Second and 3rd graders (n=41, 62, 71, 63, 976 for Phases 1-5, respectively) participated. The Fruit and Vegetable Recall Questionnaire (FVRQ), adapted from Paxton et al (2011), was administered within the classroom directly after lunch and assessed FV items taken and amounts consumed. FVs were tailored based on lunch that day. A digital photography method was the referent; students’ trays were photographed in the cafeteria before and after eating and photos were visually analyzed. Agreement between methods was calculated as rates of matches, intrusions, and omissions for each Phase. Questionnaire modifications included changing page orientation, increasing font size, reducing response options, using smiley faces for scales of measurement, and adding a training page. The match rate for FV items taken was high (Phases 1-5: 82%, 82%, 91%, 92%, 89%, respectively), with intrusions more frequent than omissions. For amounts eaten, match rates were moderate, but improved throughout Phases 1-5 (68%, 67%, 84%, 83%, 76%); students more frequently overestimated than underestimated consumption. Second and third grade students had similar match rates for items taken (87% vs. 87%) and amounts consumed (72% vs. 75%). The FVRQ is a simple, accurate instrument for assessing FV consumption among elementary students that is low-cost to administer and analyze.
