Confident Moves for Obesity
What You Need to Know Before You Apply
What is the purpose of this trial?
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.

Trial Overview
The study compares the Confident Moves (CM) online program—which helps adults with obesity increase daily physical activity through self-paced learning—to standard obesity care. Participants are randomly assigned to either CM plus usual care or usual care alone.

Experimental Treatment
Active Control
Participants assigned to the Confident Moves (CM) group also will receive the obesity centers' program and will be provided with 4 weeks of continuous (24-hour) access to the CM intervention during the data collection period. Access to the CM intervention will become available between W1 and W2, and those in this group will be notified via email. They will be encouraged to actively engage with the intervention, including completing at least 26 intervention challenges. They will be provided with login credentials to access the CM website for both the CM intervention and data collection at W1, W2, and W3.
Participants assigned to the standard care group will receive only the obesity centers' standard obesity care program during the data collection period. They will be provided with login credentials to access the CM website for data collection at wave 1 (W1), wave 2 (W2), and wave 3 (W3).
