Version V1

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.

2016-05-11 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created variable labels and/or value labels.
  • Checked for undocumented or out-of-range codes.


  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

  • One or more files in this data collection have special restrictions. Restricted data files are not available for direct download from the website; click on the Restricted Data button to learn more.
