Objective: To measure the interrater reliability of assessing the frequency of vegetable intake using mobile photos and descriptions. Design: Repeated measures design. Setting: A Midwestern university. Participants: Undergraduate students (N = 165). Measurable Outcome/Analysis: Number of times each of these vegetable subgroups were consumed daily: dark green vegetables, beans and peas, starchy vegetables, and other vegetables. Analysis: Two raters independently coded meals using mobile photos and descriptions of meals. Cohen [kappa] was calculated to determine interrater reliability. Results: A value of [kappa] = 0.9 (p < 0.001) was obtained, indicating an almost perfect agreement between the two raters. Nearly 92% of participants complied with providing photos along with descriptions of their meals. Conclusions and Implications: A frequency method using mobile photos and descriptions of meals is a reliable strategy to assess vegetable consumption. This frequency method can improve data quality, reduce participant burden, and minimize recall bias in college nutrition programs.
