Brief summary

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.

Interventions

BEHAVIORALText Based Behavioral Intervention for Physical Activity

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.

Exclusion criteria

* Does not meet the above inclusion criteria * Non-adherent to study measurement (wearing the Garmin less than 4 days) during baseline period * Averaging over 60 minutes per day of physical activity (children) or 30 minutes of physical activity per day (adults) during the baseline period as measured by the Garmin * Participant has a disability that interferes with their ability to carry out daily activities

Design outcomes

Primary

MeasureTime frameDescription
Changes in Physical Activity Minutes Over Time8 weeksParticipant physical activity will be measured by daily minutes of physical activity as collected by the Garmin monitor.
Changes in Physical Activity Steps Over Time8 weeksParticipant physical activity will be measured by a daily step count as collected by the Garmin monitor.

Secondary

MeasureTime frameDescription
Participant Engagement of Text Messages8 weeksText message engagement as measured by number of texts responded to.
Views of Participants on Intervention Preferences via Participant SurveyBaseline, 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.
Participant Engagement of the Garmin Monitor8 weeksGarmin activity monitor engagement as measured by number of wear days.
Views of Participants on intervention via Focus GroupsWeek 4, Week 8Up 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.
