Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Physical Activity Social Media Behavioral: Tweet4Wellness Behavioral: Self-monitoring Not Applicable

Detailed Description:

Sedentary behavior is a risk factor for heart disease, independent of meeting physical activity guidelines. Tweet4Wellness is an innovative light physical activity, specifically walking, intervention which randomly assigns participants to a 25-person private, online support group that will receive daily, theory-based messages as peer-to-peer discussion prompts. Many text-based interventions do not base the intervention text messages in behavior change theory, but this study will base the daily messages in the behavior change theories such as implementation intentions, social support, mindfulness, and social learning theory.

The trial will be conducted over a 6-month periods. For the first 3 months, there will be 2 groups: Group 1 will receive the Twitter intervention and a "Fitbit" triaxial pedometer to track their steps throughout the day; Group 2 will receive the Fitbit pedometer only.

For the second 3 months: Group 1 an Group 2 will track their physical activity with Fitbit only.

Arm Intervention/treatment
Experimental: Group 1: Tweet4Wellness+Self-monitoring
This group will receive the Tweet4Wellness intervention: daily theory-based peer-to-peer discussion prompt within the private Twitter-based support group for the entire 6 months of the study. They will also receive the Fitbit triaxial pedometer that will track their daily steps (self-monitoring component).
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.

Active Comparator: Group 2: Self-monitoring
This group will receive the Fitbit triaxial pedometer that will track their daily steps (self-monitoring component) for the first 3 months. For the second three months of the study, they will receive the Tweet4Wellness intervention in addition to their Fitbit self-monitoring.
Behavioral: Self-monitoring
A Fitbit is provided to the group which tracks participants' daily steps.




Primary Outcome Measures :
  1. Change in steps (physical activity) [ Time Frame: Baseline to 3 months and 6 months ]
    Steps measured by triaxial accelerometer


Secondary Outcome Measures :
  1. Support Group Engagement during the intervention [ Time Frame: 3 months ]
    Measured by # of Tweets per day sent to the group

  2. average length of prolonged sedentary periods per day [ Time Frame: baseline to 3 months and 6 months ]
    average length of uninterrupted sedentary periods per day over a seven day period
