简要总结
VA MapTrek is a mobile-phone-based web application 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 progress overlaid on Google Maps. The objective of this study is to report activity levels to veterans, thereby encouraging them to walk more. Once participants know how to text and use Google maps, no additional training is needed. VA MapTrek does not require a special app, so there are no logins or passwords to remember. Simply registering one's Fitbit and mobile phone at an initial enrollment meeting suffices.
详细描述
All consented participants will be provided with a Fitbit and instructed to wear it all day, every day for the next 9 weeks (The first few participants may require an additional week or two of wear as we will not begin the first MapTrek race until we have at least 5 participants enrolled in the study. They will be told this upon enrollment.). The enrollment process is expected to take anywhere from 15 to 45 minutes, depending on group assignment and participant familiarity with using Fitbits.
This, plus an exit survey (given via text message or phone, whichever the participant prefers), will be the extent of participation for the control group.
Members of the intervention group will be instructed on how to use MapTrek, the virtual walking race, and will also be given an instruction packet to refer to later. Data collected during the first week from the Fitbit will be used to compute baseline activity level. This baseline data will be used to place participants into an appropriate initial race group. Participants are placed into groups with other individuals who are active at a similar level, so that groups will be competitive.
Each virtual walking race will begin on Monday morning and end on Saturday night. Results of each race will be announced on Sundays. Depending on their performance each week, group assignment may change. Participants will compete in 8 week-long races over the course of the study.
Participants will receive 2-4 text messages per day including a daily status report and a link to view the race. They will also periodically receive challenge messages. If a participant completes a challenge, they will be awarded bonus steps to help move them along the route quicker.
