The backdrop to the consortium’s launch is a stubborn gap between the scale of the problem and the resources devoted to it. Eating disorders, including anorexia nervosa, bulimia nervosa and binge-eating disorder, affect millions of people worldwide and are associated with some of the highest mortality rates of any psychiatric illness, yet the research field has historically competed for attention and funding against far better-resourced areas of medicine. Scarcity does more than shrink laboratory budgets; it fractures the community itself. Clinicians, basic scientists, statisticians, carers and people who have survived eating disorders often work in parallel rather than in partnership, duplicating effort and slowing the translation of discoveries into new therapies. CoRe-ED was created to attack that fragmentation directly. Its stated mission, as an international charity, is to promote innovation in eating disorders research by empowering all voices — not only those of senior academics at wealthy institutions — and by supporting the development of new treatments. The founding bet was simple: a deliberately open, international network could accomplish what isolated, underfunded groups working alone could not.

To test whether that bet was paying off, the team behind the consortium turned its own growth into a research project. Between 25 September 2024 and 31 December 2025 — a window of roughly fifteen months — everyone who registered with CoRe-ED completed an online registration form and consented to the use of deidentified, aggregated data for research. Deidentification strips away names, contact details and other personal identifiers before analysis, so that researchers examine only group-level patterns rather than any individual’s responses. The team first profiled registrants by primary country of residence and professional or personal roles, then examined what members expected from the consortium and how they experienced it. For those expectations and experiences, the researchers applied inductive thematic analysis, a qualitative method that codes free-text responses and survey comments without imposing a predefined framework, letting themes emerge from the data itself. Three further evidence streams fed the study: feedback surveys from ten CoRe-ED events, tracked engagement with the consortium’s collaborative initiatives, and a separate overarching survey of registrants’ overall experiences. The work received ethics approval from a Bellberry Limited Human Research Ethics Committee, and every participant provided written online consent.

The headline numbers are striking for a field that has often struggled to fill a single conference room. In roughly fifteen months, 960 individuals from 37 countries across five continents registered with the consortium, a geographic spread few would have predicted for a field so often dismissed as niche. The membership is deliberately heterogeneous. Alongside academic researchers and health professionals, the register includes people with lived experience of eating disorders, advocates, representatives of not-for-profit organisations and industry professionals. That composition matters scientifically as well as symbolically. Collaborative-science research consistently shows that multidisciplinary, community-engaged teams ask different questions, access different kinds of data and reach different audiences than single-discipline groups working alone. By counting who actually signs up — rather than who is merely invited — the study provides an empirical snapshot of whether the consortium’s inclusive design attracts the full spectrum of stakeholders or only the usual academic suspects. On this early evidence, the answer is the former: the registrant base mirrors the broad coalition the founders set out to build.

What, then, did nearly a thousand people want from membership? The inductive analysis distilled registrants’ expectations into a set of recurring themes: networking and community building; contributing to and collaborating on research; learning and professional development; advocacy; the facilitation of innovation; the integration of lived experience into research; global collaboration; and mentorship. Read together, the themes amount to a diagnosis of what the field has been missing. The demand for networking and community building suggests that many registrants felt professionally isolated within their home institutions. The emphasis on learning and professional development points to gaps in training that national systems have not filled. Calls for mentorship signal that early-career researchers and emerging advocates lack structured guidance, while the repeated demand for integrating lived experience into research reflects a broader international movement to involve patients and survivors as genuine partners rather than passive subjects of study. Notably, these expectations were reported across roles and regions, indicating that the appetite for connection and co-production cuts across career stage, discipline and geography rather than being confined to any single constituency.

The consortium’s most ambitious response to those expectations is a structured initiative called the Next Big Research Idea. Instead of waiting for funding agencies to set the agenda from the top down, CoRe-ED convened 18 internationally distributed multidisciplinary teams, drawn from 20 countries, to develop collaborative eating disorders research proposals together. The format echoes the sandpit or idea-incubator models used successfully in other research domains: participants from different disciplines and backgrounds are deliberately mixed into teams, given a shared problem space and supported to co-develop project ideas that no single discipline could generate alone. In this case, the teams spanned the full stakeholder spectrum — combining researchers, clinicians and lived experience perspectives — across time zones and continents. The initiative matters for two reasons. First, it converts diffuse enthusiasm for collaboration into concrete, potentially fundable research plans, shortening the distance between an unmet clinical need and a structured proposal. Second, it operationalises the consortium’s founding principle that innovation should emerge from the whole community, including voices that traditional funding pipelines frequently filter out. By the standards of a field long labelled niche, mobilising eighteen teams across twenty countries in fifteen months is a remarkable result.

Registrants’ day-to-day experience appears to match that ambition. Feedback from the ten CoRe-ED events held during the study window, together with the overarching survey of overall experiences, indicated high satisfaction with the consortium’s activities. Respondents particularly valued the diversity of presenters, the global perspectives on display, the inclusive environment and the opportunities to learn from and connect with others. Those four factors are far from incidental. Research on professional networks shows that perceived inclusiveness and speaker diversity strongly predict whether participants return to future events, volunteer for working groups and recruit their colleagues — the behaviours that convert a mailing list into a functioning community. High satisfaction with global perspectives also suggests the consortium is not simply exporting a single national model of research culture, but genuinely knitting together different national traditions, health systems and patient communities. For an organisation whose founding premise is that every voice matters, positive feedback on inclusiveness is arguably the most important early signal that its design principles are working in practice and not merely on paper.

The study’s title names a deliberate transition: from establishment to network consolidation. In the language of network science, a young consortium must first solve the establishment problem — attracting members, establishing legitimacy and creating initial touchpoints such as a registration pathway and launch events. It then faces a harder challenge: consolidation, the conversion of a loose collection of individual sign-ups into an interconnected web of working relationships. The evidence assembled here suggests CoRe-ED is navigating that second transition. Its programming — regular events, the multidisciplinary Next Big Research Idea teams and activities oriented toward learning, mentorship and advocacy — maps closely onto the expectations registrants reported when they joined. That alignment between what members asked for at sign-up and what the organisation delivered afterwards is presented in the study as evidence that the consortium is responding to its community rather than broadcasting at it. The structure also appears designed to compound: every event and every multidisciplinary team forges new ties between members, raising the likelihood of future collaborations, co-authored papers and jointly submitted grants. In a field historically made up of small, scattered laboratories, that compounding effect may matter more than any single initiative.

There are, however, important caveats that any careful reader should weigh. The authors are not neutral observers: Professor Gemma Sharp is the founding director of the consortium, and Hao Hu and Peter Wigley are its directors, a competing interest they disclose transparently in the paper. The registrant base is likewise self-selected; people who choose to join an international consortium are by definition already motivated, and their enthusiasm may not represent the wider clinical and research community, including sceptics who never signed up. The study measures expectations, satisfaction and engagement — that is, perceptions — rather than hard outcomes. No data yet exist on whether CoRe-ED membership translates into funded grants, published trials, new therapies or improved patient outcomes, and the analysis covers only the consortium’s first fifteen months of existence. The research itself received no specific grant funding from public, commercial or not-for-profit agencies, and the article is published open access under a Creative Commons licence, allowing anyone to read the full evidence base and interrogate its conclusions firsthand.

The authors are clear about what must come next. Future research, they conclude, should examine longer-term experiences — including impacts on research outputs, mentorship, the co-design of studies and the translation of findings into health policy — to better understand how the consortium evolves in response to the needs of its international community. Those questions will determine whether CoRe-ED’s early momentum hardens into durable scientific infrastructure or fades into well-attended events. Even at this early stage, however, the study offers a template that extends well beyond eating disorders. It demonstrates that a small, dedicated team can document the growth of a global research community with much of the rigour applied to a clinical trial: a defined enrolment window, consented data collection, systematic qualitative analysis, triangulation across surveys and events, and transparent disclosure of conflicts of interest. For any underfunded field wondering whether a bottom-up, charity-led consortium can compete with traditional top-down institutions, the first fifteen months of CoRe-ED provide an unusually well-documented proof of concept — and a reminder that, in science as in medicine, community itself can be a therapeutic intervention.
