RecruitingBehavioural interventionCF Wellness ProgramThis study is a pilot randomized control trial (RCT; N=80) comparing the Cystic Fibrosis Wellness Program (CFWP) to usual care (UC) to evaluate (1) Intervention Adherence (completion of the CFWP Coaching Sessions) (2) Study Retention (completion of the Week 15 assessment) and (3) Data Quality (valid daytime and nighttime fitness tracker data). A secondary aim is to gather preliminary data to determine if the CFWP has a clinically significant signal over usual care to improve fatigue, sleep, and physical activity (PA) and reduce sedentary behavior.
