Background Although there is extensive evidence for the efficacy of online eating disorder (ED) prevention programs in clinical trials, these programs have rarely been adopted beyond the trial phase and offered to a wider audience. As risk factors for eating disorders are partly associated with overweight and overweight in turn is correlated to disordered eating, this study will offer a combined eating disorder prevention program which also promotes a balanced lifestyle to normal weight and overweight individuals alike. The efficacy of the program has been proven in previous trials. The study aims to evaluate the dissemination of a combined eating disorder prevention and health promotion program (everyBody) to women of all age groups and varying levels of ED risk status in the general population. Methods A dissemination trial will be conducted in German-speaking countries, including 4160 women from the general population. Participants will be screened to exclude participants who are likely to have an ED. Eligible participants will be allocated to one of five program arms based on their BMI and respective ED symptoms. The guided program consists of 4 to 12 weeks of weekly sessions offering CBT-based exercises, psychoeducational material, self-monitoring, and group discussions. Outcomes will be assessed according to the RE-AIM model, including measures of effectiveness, reach, adoption, implementation, and maintenance of the program. Discussion/conclusions This trial aims to disseminate a combined ED prevention and health promotion program in the general population, offering universal, selective and indicated prevention in one program. To our knowledge, it is the first trial to systematically evaluate dissemination efforts based on the RE-AIM model. This trial will be conducted as part of the EU-funded ICare (Integrating Technology into Mental Health Care Delivery in Europe) project.

为女性量身定制的在线健康促进和饮食失调预防：传播试验的研究方案。

背景尽管有大量证据表明在线饮食失调 (ED) 预防计划在临床试验中的有效性，但这些计划很少在试验阶段之后被采用并提供给更广泛的受众。由于饮食失调的风险因素部分与超重有关，而超重反过来又与饮食失调有关，这项研究将提供一个综合的饮食失调预防计划，该计划还可以促进正常体重和超重个体的平衡生活方式。该计划的有效性已在之前的试验中得到证实。该研究旨在评估向所有年龄段的女性以及普通人群中不同程度的 ED 风险状态的女性传播饮食失调预防和健康促进联合计划（每个人）的情况。方法 将在德语国家进行传播试验，包括来自普通人群的 4160 名女性。将对参与者进行筛选，以排除可能有 ED 的参与者。符合条件的参与者将根据他们的 BMI 和各自的 ED 症状被分配到五个项目组之一。指导计划包括 4 到 12 周的每周课程，提供基于 CBT 的练习、心理教育材料、自我监控和小组讨论。结果将根据 RE-AIM 模型进行评估，包括计划的有效性、范围、采用、实施和维护的措施。讨论/结论 该试验旨在在普通人群中传播 ED 预防和健康促进相结合的计划，在一个计划中提供普遍、选择性和指示的预防。据我们所知，这是第一个基于 RE-AIM 模型系统地评估传播工作的试验。该试验将作为欧盟资助的 Icare（将技术整合到欧洲的心理保健服务）项目的一部分进行。
