Confident Moves Intervention Efficacy Trial: Obesity Care Settings
348 participantsStarted 2026-07
Plain-language summary
The objective of this study is to evaluate the efficacy of the Confident Moves (CM) intervention on device-measured physical activity (PA) and the whole person health index in adults with obesity, compared to standard obesity care alone. Confident Moves (CM) is a web-based physical activity (PA)-promoting research intervention developed by the study team to support adults with obesity. CM is not a medical or clinical treatment; rather, it is designed to promote daily PA through structured, self-paced online learning activities. The intervention has been previously pilot-tested in a feasibility study, which demonstrated its acceptability, safety, and feasibility and informed refinements to study procedures. CM aims to strengthen participants' confidence, knowledge, and behavioral skills related to PA across multiple everyday contexts. The intervention is delivered through a secure, ISU-managed website, with access limited to enrolled participants and authorized research personnel. Only study staff have access to participant data, and data are used solely for research purposes.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
