Remote Behavioral Program to Reduce Sitting Time in Men with Prostate Cancer Using Fitbit and Specialist Support Over 12 Weeks

What this Trial Is About

Researchers are evaluating a 12-week behavioral intervention designed to reduce sedentary behavior among prostate cancer survivors PCS. The study compares this intervention, which includes FitBit use and six behavioral support sessions guided by the Multi-Process Action Control M-PAC framework, to a control group that receives only a FitBit and access to public health physical activity resources. The study aims to measure changes in sedentary behavior immediately after the intervention and six months later, while also assessing impacts on physical activity, motivation, sleep quality, social support, physical function, quality of life, fatigue, disability, and mental health. Participants in the intervention group receive a FitBit Inspire 2 and six remote behavior change sessions delivered bi-weekly by a movement specialist, including four one-on-one sessions and two group webinars. They will monitor daily steps and work to increase their baseline step count progressively across phases. The control group receives the same FitBit device and an orientation session but only access to publicly available active living resources without additional behavioral support. The intervention sessions focus on planning, goal setting, social support, and habit formation based on the M-PAC theoretical framework. During the study, participants will wear activPAL inclinometers to objectively measure changes in sedentary behavior and physical activity at baseline, after the 12-week intervention, and at a 6-month follow-up. Self-reported sedentary behavior and physical activity will also be assessed using validated questionnaires. Researchers will monitor motivational factors, sleep, social support, physical function, and patient-reported outcomes such as quality of life, fatigue, disability, and mental health. The total participation involves these assessments across the intervention and follow-up periods, with data collected remotely.
