In this commentary, we call on the field to think critically about how to maximize not only the volume but also the real-world impact of the next 50 years of eating disorder research. In particular, we highlight the importance of creating a research ecosystem that nurtures methodological diversity and centers collaborative, participatory research in partnership with people with lived experience. We also underscore the importance of conducting inclusive research that makes space for the full diversity of eating disorder presentations and the people who experience them.

We propose that to move the field forward, assessment efforts strive for the ambitious and necessary goal of creating an omnibus tool that comprehensively captures the full spectrum of eating-disorder presentations. Our arguments are grounded in three key points: (1) there is a pressing need to apply evidence-based approaches in scale development; (2) the EDE's widespread use does not warrant its continued endorsement; and (3) it is essential for the field to critically examine the consequences of continued reliance on the EDE. We provide illustrative examples from other fields in which newer measures were developed and widely adopted, leading to improvements in those fields.

Their findings suggest preliminary acceptability, feasibility, and symptom improvements, contributing to the growing evidence-base for D-SSIs in disordered eating. This commentary outlines five key challenges that must be addressed to translate pilot findings into real-world impact. First, the uptake of D-SSIs is often low, likely due to help-seeking barriers and septicism towards this approach. Peer-led, promotional campaigns may boost engagement of D-SSIs in young people. Second, despite their brevity, D-SSI completion is not assured. Strategies such as automated reminders, peer or AI-guided support, and youth co-design may improve adherence. Third, economic evaluations are rare but critical for determining whether D-SSIs offer cost-effective support within resource-limited student services. Fourth, trials should examine mechanisms and durability of change, with complementary D-SSIs offering promising directions. Finally, meaningful integration into care pathways is critical. D-SSIs may serve as stand-alone supports, early engagement tools, or components of stepped-care models. Lack of response could signal the need for intensive care, while successful use may increase openness to further help-seeking. Addressing these challenges with informative, implementation-ready trials will be key to realizing the full potential of D-SSIs in addressing eating disorders in university students and advancing youth mental health care more broadly.</p>","PeriodicalId":51067,"journal":{"name":"International Journal of Eating Disorders","volume":"58 9","pages":"1693-1696"},"PeriodicalIF":4.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/eat.24487","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144318619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
