Active KC: a Text Message Based Intervention for Physical Activity

Active KC will involve delivering PA support tools to individuals interested in increasing their physical activity. The tools involve provision of a Garmin wearable activity monitor and participant-tailored behavior change supports (e.g., goal setting and monitoring) delivered through text messaging and a corresponding study website.

Treatment and study plan

Text Based Behavioral Intervention for Physical Activity

Behavioral

Text intervention messaging will be sent through an automated text messaging service programmed by the CM Informatics team, which has been approved by the institution. Participants will be asked to wear Garmin physical activity monitor to provide physical activity information throughout the intervention. The Garmin is worn like a wristwatch. The device is small and non-intrusive. The Garmin device is a consumer wearable that will automatically detect and track activity such as walking, running, and cycling. The text messages incorporate information from the Garmin monitor to support physical activity.

Primary outcomes

  1. Changes in Physical Activity Minutes Over Time

    Time frame: 8 weeks

    Participant physical activity will be measured by daily minutes of physical activity as collected by the Garmin monitor.

  2. Changes in Physical Activity Steps Over Time

    Time frame: 8 weeks

    Participant physical activity will be measured by a daily step count as collected by the Garmin monitor.

Secondary outcomes

  1. Participant Engagement of Text Messages

    Time frame: 8 weeks

    Text message engagement as measured by number of texts responded to.

  2. Views of Participants on Intervention Preferences via Participant Survey

    Time frame: Baseline, End of Study (8 weeks)

    Adults will complete a baseline and follow up adult survey and children will complete a baseline and follow up child survey with help from their caregiver when appropriate. Participant surveys may be distributed via hardcopy, email, or text message.

  3. Participant Engagement of the Garmin Monitor

    Time frame: 8 weeks

    Garmin activity monitor engagement as measured by number of wear days.

  4. Views of Participants on intervention via Focus Groups

    Time frame: Week 4, Week 8

    Up to 15 focus groups will be hosted throughout and after the intervention period. A subsample of participants will be selected to take part in focus groups conducted after week 4 and week 8. These focus groups will ask about participant experiences with the Garmin monitors and text messaging along with general perceptions of the intervention. Focus groups will be hosted virtually using Teams or in person and will be recorded. All participants will have the option to keep their cameras off during virtual focus groups.
