Study Summary
MapTrek is a mobile-phone-based web app that allows participants to take a virtual walk in interesting locations around the world while tracking their progress against the progress of other veterans on an interactive map. Steps are counted using a commercially available triaxial accelerometer (e.g. Fitbit), and users see their own updated progress overlaid on Google Maps, with Google Maps features (e.g. zooming, street view, etc.) available. The objective is to report activity levels in the virtual environment to veterans, thereby encouraging them first, to walk more every day, and second, to maintain these new increased levels of physical activity.
Primary Outcome
Ability (smartphone ownership, texting skill) to participate will be assessed via self-report from the participant.
Interventions
- BEHAVIORAL Fitbit
