“Tweet4Wellness: An Online Virtual Support Group for Promoting Increased Physical Activity”
The purpose of this study is to determine whether a Twitter-based intervention with a private, online support group can significantly increase number of walking steps compared to self-monitoring of physical activity alone or a control group in sedentary women at a women's heart clinic.
Behavioral - Tweet4Wellness
A daily, behavior change theory-based intervention message is sent to a private, 25-person online Twitter-support group to prompt peer-to-peer discussion. Participants receive individual text messages to encourage group participation (e.g. 'thank you for participating' or 'please participate tomorrow'). Participants also receive weekly individual messages giving them daily step goals for the week based on their previous week's daily step average, recorded from Fitbit.
Behavioral - Self-monitoring
A Fitbit is provided to the group which tracks participants' daily steps.
