The findings also suggest the relationship between eating and psychotic disorders is mediated, to an extent, by the presence of mood instability traits. Future research could extend the present study\u2019s findings through assessing whether specific eating disorders are more significantly related to psychotic disorders than others.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s40337-022-00664-0","type":"journal-article","created":{"date-parts":[[2022,10,18]],"date-time":"2022-10-18T11:04:10Z","timestamp":1666091050000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Co-occurring psychotic and eating disorders in England: findings from the 2014 Adult Psychiatric Morbidity Survey"],"prefix":"10.1186","volume":"10","author":[{"given":"Ellen","family":"Rodgers","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven","family":"Marwaha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clara","family":"Humpston","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,10,18]]},"reference":[{"issue":"8","key":"664_CR1","doi-asserted-by":"publisher","first-page":"1649","DOI":"10.1017\/S0033291711002807","volume":"42","author":"R Dutta","year":"2012","unstructured":"Dutta R, Murray RM, Allardyce J, Jones PB, Boydell JE.
