Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The prevention program is based on improving protective factors such as body appreciation, body image flexibility, intuitive eating, and acceptance. It will be compared to a credible placebo (expressive writing).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Eating disorders (EDs) are common and cause significant morbidity and mortality. Due to stigma, only 25% seek help and only 50% fully recover after receiving treatments. Large-scale prevention is urgently needed to reduce the emergence and burden of EDs at a population level. However, current prevention programs do not meet requirements for efficient and economically attractive large-scale implementation. The main aim of this project is to investigate the efficacy and cost-effectiveness of a scalable, brief, and interactive prevention program based on reinforcement of protective factors against EDs using a randomized controlled design. A focus on protective factors disrupts the processes by which risk factors increase the probability for EDs to emerge and minimizes the risks for stigmatization.
Research questions:
1. How effective is an internet-based prevention program, that reinforces protective factors against EDs, in reducing the onset of EDs 6, 12, 24, and 36 months post-intervention?
2. Does the intervention reduce the incidence of EDs through enhancement of specifically targeted protective factors (mediators)?
3. Is prevention of EDs based on reinforcement of protective factors cost-effective?
4. How do the participant experience their participation in these two interventions?
Other research questions concern gender differences in enrollment and compliance, potential moderators of outcome, participation in booster sessions, and potential risk for stigma.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Enhancing protective factors
Participants will learn to improve their body image through body appreciation tasks, body image flexibility and focus on body functionality appreciation. They also learn to focus on important life values, be more accepting of themselves, and learn to eat regularly and with attention to bodily needs and signals. This is don in interactive ways, and by using a cognitive dissonance frame.
Enhancing protective factors
Participants will watch some short movies and infographics, and will be asked to argue for the importance of body image flexibility, body functionality appreciation, etc.
Expressive writing
Participants will be instructed to write about any thoughts, feelings, images, memories, interceptions, ideas or emotions related to their body for the same during as the active intervention (i.e., 40 minutes/week across four consecutive weeks).
Expressive writing
Participants will reflect and write about any cognitions or emotions they can have in relation to their bodies.
