Mobile telephones with an integrated camera can provide a unique mechanism for collecting dietary information that reduces burden on record keepers. The purpose of this study was to receive feedback from users during the interaction design of a mobile phone food record (mpFR) for adolescents that will eventually translate to an accurate account of daily food and nutrient intakes. A total of 78 adolescents (26 males, 51 females) ages 11‐18 y were recruited to participate in breakfast and lunch meal sessions and provide feedback about the mpFR. Prior to their first meal, all participants received instruction for using the mpFR. Volunteers captured an image of their meals (or snacks) before and after eating using the mpFR. After using the mpFR, the majority of participants (79%) agreed that the software was easy to use. Also, the students participated in a training activity where they received additional instruction on capturing images in various snacking situations. As a result of the additional training, significantly more participants agreed that taking images before snacking would be easy (10% vs 28%, p =0.01), as well as, after snacking (19% vs 38%, p <0.001). Though adolescents readily adopt new technologies, formative evaluation is needed to tailor technology. Further, these results suggest that additional training in using a new technology may improve the accuracy among users. Grant Funding Source NIH‐NIDDK
