In this paper, we report on the process of co\u2010producing a theory; in this case, a graphical articulation of theory in the form of a logic model, which describes how contextual factors influence children's health.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We undertook a series of three online co\u2010production workshops, involving 18\u201320 participants in each, and worked with an advisory group of experts with professional and lived expertise. An online virtual whiteboard was used to support the identification of factors that contributed to poorer childhood health, explanations for these factors, and connections between different factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Driven by government strategy, we initially focussed our work on childhood obesity. However, co\u2010production was transformational in switching the focus of the logic model away from a narrow focus on Body Mass Index as a measure of obesity, to a more holistic theory of factors that shape children's health, recognised as the intersection between healthy eating, physical activity and mental well\u2010being. Theorising with a diverse range of co\u2010producers helped us to recognise the stigmatising impacts that an exclusive focus on clinical measures of children's health can have, and the way that a narrow clinical focus inhibits theorising the complexity and drivers of poorer health.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Co\u2010production led to a switch in theorising away from narratives of children's health that focus closely on personal responsibility, towards narratives that explore structural and contextual drivers of health.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patient or Public Contribution<\/jats:title>\n                    <jats:p>The logic model was entirely driven by the contributions of researchers, those with lived experience (e.g., as parents and\/or who have experienced poor health), and those with professional experience (e.g., as teachers)\u00a0who worked together to co\u2010produce the model. An advisory group composed of people with a similar range of expertise helped to shape the conduct of co\u2010production and dissemination (including in the preparation of this manuscript).<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/hex.70346","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T07:41:09Z","timestamp":1754293269000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Public Involvement in Complex Theorising: A Co\u2010Produced Logic Model of the Role of Context in Shaping Child Health"],"prefix":"10.1111","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7016-978X","authenticated-orcid":false,"given":"Dylan","family":"Kneale","sequence":"first","affiliation":[{"name":"EPPI Centre, Social Research Institute University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0359-6423","authenticated-orcid":false,"given":"Alison","family":"O'Mara\u2010Eves","sequence":"additional","affiliation":[{"name":"EPPI Centre, Social Research Institute University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9935-7840","authenticated-orcid":false,"given":"Bridget","family":"Candy","sequence":"additional","affiliation":[{"name":"Marie Curie Palliative Care Research Department, UCL Division of Psychiatry University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lizzie","family":"Cain","sequence":"additional","affiliation":[{"name":"Innovation Unit London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7901-1797","authenticated-orcid":false,"given":"Jessica","family":"Catchpole","sequence":"additional","affiliation":[{"name":"Department of Nursing, School of Health &amp; Psychological Sciences, City St George's University of London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2466-571X","authenticated-orcid":false,"given":"Angela","family":"Chesworth","sequence":"additional","affiliation":[{"name":"Independent Patient Advocate  UK"},{"name":"Co\u2010production Collective University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9571-269X","authenticated-orcid":false,"given":"Sandy","family":"Oliver","sequence":"additional","affiliation":[{"name":"EPPI Centre, Social Research Institute University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5469-8649","authenticated-orcid":false,"given":"Katy","family":"Sutcliffe","sequence":"additional","affiliation":[{"name":"EPPI Centre, Social Research Institute University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niccola Hutchinson","family":"Pascal","sequence":"additional","affiliation":[{"name":"Co\u2010production Collective University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4805-4190","authenticated-orcid":false,"given":"James","family":"Thomas","sequence":"additional","affiliation":[{"name":"EPPI Centre, Social Research Institute University College London London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,8,4]]},"reference":[{"key":"e_1_2_11_2_1","unstructured":"J.Noyes M.Hendry S.Lewin C.Glenton A.Booth andR.Garside. 2015.
