Enhancing Adherence by Building Online Communities
Enhancing Adherence by Building Online Communities
The purpose of this study is to determine whether online peer support will increase adherence
 to an internet-based pedometer walking program.
Stepping Up to Health with eCommunities is a study that takes what we already know about
 motivating sedentary, chronically ill people to walk, and begins to explore what it takes to
 keep people motivated to exercise over time: the ability to self-monitor behavior with
 accurate ecological momentary assessments.

 We have theorized that peer support, monitoring and competition are ways in which people can
 stay motivated to meet their walking goals; thus, we have built into this intervention online
 forums for participants to communicate with each other and garner support, as well as a pilot
 one-to-many competitive game based on the percent of an individual's goal met.

 Our research question is whether online community participation can increase adherence to an
 Internet-mediated walking program, which consists of an uploading pedometer, and going to a
 website to receive graphical and textual feedback as to whether participants are meeting
 gradually increasing walking goals. Three hundred participants will spend four months in this
 randomized, controlled trial to compare the intervention alone to the intervention plus
 online community support.
