FIT4Life Text Message Program

FIT4Life is a text message based physical activity project that includes one baseline week and 26 weeks of intervention delivery. Study participants will be provided with fitness trackers to support their physical activity goals. The text messages are intended to motivate participants to engage in physical activity throughout the week, but do not prescribe specific exercises/workout regimens for participants to follow.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: High Arm; High-arm participants will receive daily messages related to wear reminders, encouragements, congratulatory content, and behavior change based on the activity tracker data. Step counts from the activity tracker are included in some messages to track and facilitate step goals. Some text message content asks for a response from the participant to help tailor later messages for behavior change support.	Behavioral: text messages; There will be two arms for the texting intervention: high and low. Both arms will receive text messages, but the frequency of the messages will vary by arm. Text intervention messaging will be sent through an automated text messaging service programmed by the CM Research Informatics team, which has been approved by the institution.
Experimental: Low Arm; Low arm participants will receive weekly messages related to reminders to wear their activity tracker and tips on how to use the tracker.	Behavioral: text messages; There will be two arms for the texting intervention: high and low. Both arms will receive text messages, but the frequency of the messages will vary by arm. Text intervention messaging will be sent through an automated text messaging service programmed by the CM Research Informatics team, which has been approved by the institution.
