Questions? Mobile health study

Can I use my own Fitbit if I already own one?
No, we ask that you use the Fitbit that we have provided to you for this study.

Can I use the Fitbit when not sampling? After the study is over?
Yes, you can use the Fitbit as much as you like in between sampling periods, and you can keep it after the study ends.

Is this study sponsored by Fitbit?
No, this study is not sponsored by Fitbit. The National Cancer Institute is funding this study. We are using Fitbit devices to measure activity, heart rate, and sleep, but there is no relationship between the study and the Fitbit company.

Can I choose the color of my Fitbit?
At this point, we can only provide black Fitbit devices.

Can I look at all of my steps/activities during the sampling period?
Yes, you can interact with the Fitbit device and the Fitbit app during the study.

Should I change my exercise/walking routine during the sampling period?
No, the goal of this study is to measure your normal physical activity patterns, so we do not want you to change your behavior for this study.

What happens if I lose or break my Fitbit?
If you lose or break your Fitbit, please contact us (NHS3Mobile@channing.harvard.edu), and we may be able to provide a new device.

What if I get injured (sprained ankle, broken arm) between sampling periods and don’t have the same walking/sleeping routine?
If this occurs, please email us at NHS3Mobile@channing.harvard.edu. You may still be able to remain in the study.

What happens if I move (new house/apartment/city) while I’m in the study?
This will not affect your participation in the study. Please continue to follow the study protocol.

Can I delete the apps off of my phone between sampling periods?
No, please keep the apps on your phone for the entire year of the study.
