Brief Summary:
Previous studies suggest self-regulatory techniques including self-monitoring, and SMS text-messaging as an intervention modality, can modify health behaviors including physical activity (PA). The primary purpose of this study was to examine change in objectively measured PA in a randomized controlled pilot trial that tested a wearable sensor/device (Fitbit One) for self-monitoring and SMS text-messaging prompts to promote PA in overweight/obese adults. In a 2-group design, 67 participants were provided the Fitbit One and half were randomized to receive 3 daily SMS-based PA prompts. A Fitbit One was provided to facilitate self-monitoring with a wearable tracker for instant feedback and website of daily PA summaries. Outcome measures were number of steps and minutes of PA by intensity-level using two accelerometers: Actigraph GT3X+ (primary) at baseline and 6-week follow-up and Fitbit One (secondary) at baseline and weeks 1-6. The main hypothesis was that text messaging plus the Fitbit One would show a greater increase in steps and minutes of PA compared to only the Fitbit One at 6-week follow-up.

Arm Intervention/treatment
Experimental: SMS Text Messages & Fitbit One
All study participants were provided a Fitbit One to facilitate self-monitoring of PA. Those who were randomly assigned to the intervention group were asked to indicate 3 preferred times of the day to receive text message prompts to do PA throughout the 6-week study period.
Behavioral: SMS Text Messages & Fitbit One
The primary aim was to test text-messaging in its basic form to prompt physical activity. A secondary aim was to examine the effects of the Fitbit One.

Active Comparator: Fitbit One Only
An active control group was also provided the Fitbit One to facilitate self-monitoring of PA throughout the 6-week study period.
Behavioral: Fitbit One Only
Active controls received a Fitbit One to facilitate self-monitoring (and no text messages)

Primary Outcome Measures :
  1. steps per day (Actigraph GT3X+) [ Time Frame: up to 6 weeks ]
    Number of steps per day was measured using Actigraph GT3X+ at baseline and 6-week follow-up


Secondary Outcome Measures :
  1. Minutes per week of physical activity by intensity level (Actigraph GT3X+) [ Time Frame: up to 6 weeks ]
    Moderate-to-vigorous intensity physical activity (MVPA) (min/wk) and total PA (min/wk) were assessed using Actigraph GT3X+ at baseline week and 6-week follow-up


Other Outcome Measures:
  1. Physical activity levels (Fitbit One) [ Time Frame: up to 6 weeks ]
    Physical activity by intensity level (i.e., fairly and very active minutes and total active minutes) were assessed using the Fitbit One throughout the entire duration of the study

  2. Steps per a day (Fitbit One) [ Time Frame: up to 6 weeks ]
    Steps per day were assessed using the Fitbit One throughout the entire duration of the study
