Early or partial results. Treat as a signal, not a conclusion.
This is a registered protocol for a three-month randomized trial of a theory-based multi-modal digital intervention (AI coaching, gamified apps, real-time feedback) versus health education in overweight and obese adolescents aged 12–18 years. No results are posted in this registry record; the study is currently recruiting, and outcomes will be measured by self-reported healthy and unhealthy weight control behaviors on the WCB Scale at baseline, one month, and three months post-intervention.
Interventional, Randomized, Parallel, Single masking, Treatment purpose. Obesity, Adolescent, Weight Change, Body, Weight Stigma; age from 12 Years; to 18 Years; accepts healthy volunteers. Intervention: Multi-Modal Digital Intervention Group. Compared with: Control Group (General Health Education) — Active Comparator. n = 200. 2 sites: Taiwan.

Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians should await final results before adopting this digital intervention approach. If the trial demonstrates efficacy in promoting healthy weight control behaviors and reducing unhealthy behaviors, it may offer a scalable, technology-enabled option for adolescent obesity management.
This is a registered trial protocol with no results reported; it describes planned methodology for a behavioral intervention in adolescent obesity using surrogate endpoints (self-reported weight control behaviors), making it preliminary evidence pending completion and outcome publication.

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 key findings. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT06920862). This is a study registration, not published results. Lead sponsor: National Yang Ming Chiao Tung University. Recruitment status: RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 200 participants (ESTIMATED). Conditions: Obesity, Adolescent, Weight Change, Body, Weight Stigma. Interventions: BEHAVIORAL: Multi-Modal Digital Intervention. Primary outcome measures: Change in Healthy Weight Control Behaviors as Measured by the Weight Control Behavior (WCB) Scale , Baseline (T0), 1 month post-intervention (T1), 3 months post-intervention (T2); Change in Unhealthy Weight Control Behaviors as Measured by the Weight Control Behavior (WCB) Scale , Baseline (T0), 1 month post-intervention (T1), and 3 months post-intervention (T2). Brief summary: The goal of this randomized controlled trial is to evaluate the effectiveness of a multi-modal digital intervention, based on the Theory of Planned Behavior (TPB), in promoting healthy weight control behaviors among overweight and obese adolescents. This study also aims to reduce the risk of unhealthy weight control behaviors by leveraging artificial intelligence-driven coaching, interactive platforms, gamified applications, and real-time feedback mechanisms. The main questions this study aims to answer are: 1. Can a multi-modal digital intervention effectively modify adolescents' primary beliefs underlying TPB constructs (attitude, subjective norms, and perceived behavioral control)? 2. How do TPB constructs influence weight control intentions, and how do these intentions translate into either healthy or unhealthy weight control behaviors? What role do adolescents' body image, body satisfaction, and mental health play in moderating the relationship between weight control intention and behavior? Participants will: 1. Be adolescents aged 12-18 years with a BMI ≥ 85th percentile. 2. Be randomly assigned to either the intervention group (multi-modal digital intervention) or the control group (general health education). 3. Engage in AI-driven coaching, interactive digital sessions, and gamified experiences tailored to TPB constructs. 4. Complete biweekly sessions over a period of three months (each session lasting two hours). 5. Receive personalized feedback and real-time monitoring through the Virti platform. 6. Participate in follow-up assessments at one month and three months post-intervention. Researchers will compare the intervention group to the control group to determine whether the multi-modal digital intervention leads to a higher adoption of healthy weight control behaviors and a lower prevalence of unhealthy weight control behaviors.
