Confident Moves Intervention Efficacy Trial: Obesity Care Settings

Confident Moves Intervention Efficacy Trial: Obesity Care Settings

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.

Inclusion Criteria:

• Age 18-64 years
• Body Mass Index (BMI) ≥ 25 kg/m²
• Access to a technological device (e.g., computer, smartphone) capable of supporting the online intervention
• Not currently enrolled in another physical activity (PA) intervention (except standard obesity care programs at participating centers)
• Willingness to wear a wrist worn accelerometer for two separate 7 day monitoring periods
• Willingness to respond to study related communications (e.g., email, text, phone call)

Exclusion Criteria:

- Failure to meet one or more of the inclusion criteria
