Postintervention follow-up period (months 4 to 6)
The three-month postintervention follow-up period (months 4–6) explored engagement with the program beyond the 3-month intervention. At the end of the intervention, peer mentors strongly encouraged participants to continue using their Fitbit to track their activity and continue participating in the Fitbit Community. However, there were no scheduled contacts or video sessions, nor did peer mentors monitor Fitbit activity during the follow-up period.
