(41st Biennial Convention) Purpose:�Inadequate fruit/vegetable intake is linked to the leading causes of global mortality and rise in obesity (World Health Organization, 2009). Traditional dietary assessment methods have limited sensitivity in detecting changes in fruit/vegetable consumption. Advances in mobile technologies may reduce reporting burden while enhancing effectiveness of fruit/vegetable recording, warrenting�further study. The purpose of this project was to test the effectiveness of a technology-based method of dietary assessment for fruit/vegetables using cell phones with digital picture capability, for memory prompt in conjunction with MyPyramidtracker.gov website.� Methods: A quasi-experimental repeated measures design was used. The research questions were: 1) What is the effectiveness of recording fruit/vegetable consumption using cell phone digital pictures for memory prompt in conjunction with the MyPyramid Tracker website as compared to MyPyramid Tracker website alone; and 2) What is the acceptability and feasibility of these methods for recording diet among youths? Results: Data was collected from 69 college-age students enrolled in a southwestern university in the fall of 2010. Subjects recorded three days of diet in MyPyramid Tracker using memory only and three days adding cell phone digital pictures as a memory prompt over a 2 week period. A mixed-model ANOVA supported a statistically significant difference in the cell phone for memory prompt fruit/vegetable scores, F (1, 66) = 3.904, p = .05. Data for research question two was collected from focus groups.� Conclusion: Digital cell phone pictures were more effective than MyPyramid Tracker alone and may contribute to increased accuracy of recording fruit/vegetable consumption. Focus groups suggested�both usability and acceptablility of technology for recording diet in this population. Roger's theory of Diffusion of Innovation is suggested as a possible theoretical model for testing technology-based methods of fruit/vegetable consumption.
