Study Details

Brief 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.

Interventions and Outcome Measures

Arms

no intervention: Standard Care Group

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).

experimental: CM Group

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.

Interventions

Confident Moves (CM) Intervention

Confident Moves (CM) is a web-based physical activity (PA) intervention designed to integrate with obesity care and support daily PA in adults with obesity. A 2025 feasibility trial supported the development of a future randomized controlled trial and identified areas for refinement. Grounded in social cognitive theory, CM targets self-efficacy through structured learning activities such as games, videos, lectures, and self-reflection, incorporating behavior change techniques like goal setting and action planning. The online program includes seven components addressing multiple PA domains and mindfulness, delivered over 4 weeks with flexible access.

Primary outcome measure

  • ActiGraph wGT3X-BT [ Time Frame: At W1 (Week 1-4) and W3 (Week 13-16) ]
  • Whole Person Health Index (WPHI) scale [ Time Frame: At W1 (Week 1-4) and W3 (Week 13-16) ]
