ObjectiveTo develop and test messages and a mobile phone delivery protocol designed to influence the nutrition and physical activity knowledge, attitudes, and behavior of adolescents.DesignNine focus groups, 4 classroom discussions, and an 8-week pilot study exploring message content, format, origin, and message delivery were conducted over 12 months using a multistage, youth-participatory approach.SettingYouth programs at 11 locations in Arizona.ParticipantsRecruitment was coordinated through youth educators and leaders. Eligible teens were 12-18 years old and enrolled in youth programs between fall 2009 and 2010.Phenomenon of InterestAdolescent preferences for messages and delivery of messages.AnalysisQualitative data analysis procedures to generate themes from field notes.ResultsOne hundred seventy-seven adolescents participated in focus groups (n = 59), discussions (n = 86), and a pilot study (n = 32). Youth preferred messages with an active voice that referenced teens and recommended specific, achievable behaviors; messages should come from nutrition professionals delivered as a text message, at a frequency of ≤ 2 messages/day.Conclusions and ImplicationsMore than 300 messages and a delivery protocol were successfully developed and tested in partnership with adolescents. Future research should address scalability of texting interventions; explore dose associated with changes in knowledge, attitudes, and behaviors; and offer customized message subscription options.
