Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07623772). This is a study registration, not published results. Lead sponsor: Iowa State University. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 348 participants (ESTIMATED). Conditions: Obesity, Overweight. Interventions: BEHAVIORAL: Confident Moves (CM) Intervention. Primary outcome measures: ActiGraph wGT3X-BT , At W1 (Week 1-4) and W3 (Week 13-16); Whole Person Health Index (WPHI) scale , At W1 (Week 1-4) and W3 (Week 13-16). 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.
