移动的技术有望改善饮食和体育活动，但很少有人关注青少年喜欢和使用的程序。这项研究开发了一个个人数字助理（PDA）计划，以促进主要是低收入，少数民族女孩的水果和蔬菜（FV）的摄入量增加。本研究采用了三个阶段的社区参与的过程，包括（一）参与的学生咨询委员会（SAB），以确定舒适的PDA;（二）原型I的早期测试和快速重新设计的SAB和（iii）原型II的可行性测试在一个新的样本的女孩。第一阶段的结果显示，女孩对PDA感到满意。在第二阶段对原型I的测试表明，可接受性参差不齐，女孩对47.3%的提示作出了反应。女孩们想要更多的提醒，在监测FV的责任，帮助满足日常目标和免费音乐下载的基础上使用的程序。对PDA进行了重新程控，在第3阶段中对原型II进行的测试表明使用情况明显改善（78.3%），FV摄入量增加（每日1.8 ± 2.6份），总体满意度良好。研究结果表明，移动的技术设计与青年的早期投入是一个有前途的方式来改善青少年的健康行为。
Mobile technologies hold promise for improving diet and physical activity, but little attention is given to creating programs that adolescents like and will use. This study developed a personal digital assistant (PDA) program to promote increased intake of fruits and vegetables (FV) in predominately low-income, ethnic minority girls. This study used a three-phase community-engaged process, including (i) engagement of a Student Advisory Board (SAB) to determine comfort with PDAs; (ii) early testing of Prototype I and rapid re-design by the SAB and (iii) feasibility testing of Prototype II in a new sample of girls. Phase 1 results showed that girls were comfortable with the PDA. Testing of Prototype I in Phase 2 showed that acceptability was mixed, with girls responding to 47.3% of the prompts. Girls wanted more reminders, accountability in monitoring FV, help in meeting daily goals and free music downloads based on program use. The PDA was reprogrammed and testing of Prototype II in Phase 3 demonstrated marked improvement in use (78.3%), increases in FV intake (1.8 ± 2.6 daily servings) and good overall satisfaction. Findings suggest that mobile technology designed with the early input of youth is a promising way to improve adolescent health behaviors.
