The principal aim of this study was to investigate what dimensions of perfectionism mostly represent ON. Moreover, it was evaluated if dieting impacted the presence of orthorexic features and perfectionistic behaviour. Methods: The sample consisted of two groups\u2014the \u201cDiet\u201d (n = 93), and the \u201cNo Diet\u201d (n = 94) groups\u2014composed of people with high and low orthorexic tendencies, respectively. Participants filled out self-report questionnaires to investigate orthorexic tendencies and different facets of perfectionism. Results: Analyses highlighted that people with high orthorexic tendencies showed higher perfectionistic features and that ON had a significant relationship with different facets of perfectionism. No interactions with diet were found. Therefore, no other differences were highlighted when the group type (Diet\/No Diet) was considered. Conclusions: Regardless of diet, different facets of perfectionism characterise ON: perfectionism as a personality trait and perfectionism related to EDs and to obsessive\u2013compulsive features. Our results evidenced that perfectionism could also be considered a useful construct in the conceptualization of orthorexia nervosa.<\/jats:p>","DOI":"10.3390\/nu15153289","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T01:03:25Z","timestamp":1690333405000},"page":"3289","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Perfectionism or Perfectionisms in Orthorexia Nervosa"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7061-2932","authenticated-orcid":false,"given":"Caterina","family":"Novara","sequence":"first","affiliation":[{"name":"Department of General Psychology, University of Padova, Via Venezia 8, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3778-9634","authenticated-orcid":false,"given":"Sara","family":"Piasentin","sequence":"additional","affiliation":[{"name":"Department of General Psychology, University of Padova, Via Venezia 8, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sofia","family":"Mattioli","sequence":"additional","affiliation":[{"name":"Department of General Psychology, University of Padova, Via Venezia 8, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6692-8923","authenticated-orcid":false,"given":"Susanna","family":"Pardini","sequence":"additional","affiliation":[{"name":"Department of General Psychology, University of Padova, Via Venezia 8, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3609-1851","authenticated-orcid":false,"given":"Eleonora","family":"Maggio","sequence":"additional","affiliation":[{"name":"Department of General Psychology, University of Padova, Via Venezia 8, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"key":"ref_1","unstructured":"Bratman, S., and Knight, D.
