Principal Investigator(s): Flatley Brennan, Patricia, University of Wisconsin-Madison; Kim, Katherine, San Francisco State University; Sabee, Christina, San Francisco State University; Bodenheimer, Tom, University of California-San Francisco


This study examined the potential of collecting observations of daily living (ODLs) via mobile devices for youths who are managing obesity and are at risk for depression and anxiety. Leveraging ( utilities and data storage platform, the iN Touch design team developed an application for the iPod Touch that study participants used to record their physical activity, food intake, socialization and mood. Study participants shared this information with their lay health coaches and collaboratively set goals with them. The data file contains the ODL information collected with the iPod Touch application.
