Studying integrative cognitive processes, such as metacognition, may reveal new mechanisms of perfectionism\u2019s influence on the clinical manifestations of AN.\r\nAIM: The assessment of the moderating effect of metacognition on perfectionism associated with BMI and body image in patients with AN.\r\nMETHODS: A cross-sectional study was conducted involving patients with AN who were undergoing inpatient treatment. Perception of one\u2019s own body was assessed using the Body Image Questionnaire. Perfectionism was assessed using the Multidimensional Perfectionism Scale. The level of metacognition of patients was assessed using the Metacognition Assessment Scale-Abbreviated, which evaluates Self-reflectivity, Understanding the other\u2019s mind, Decentration, and Mastery (the ability to develop adaptive strategies for coping and behaviour regulation). BMI was also recorded.\r\nRESULTS: A total of 130 patients were examined. At a Mastery score of \u22654 higher perfectionism scores were associated with an increase in BMI, and at a Mastery level of \u22641 a higher level of perfectionism was associated with decreasing of BMI. Even with minimal Self-reflectivity scores (\u22652), the negative effect of perfectionism on body image was evident. Body image disturbance was positively correlated with perfectionism. No correlations were found between BMI and perfectionism and between BMI and body image disturbance.\r\nCONCLUSION: The effect of perfectionism on body image disturbance and BMI in patients with AN depends on the magnitude of Self-reflectivity and Mastery. The obtained data indicate the necessity of incorporating psychotherapy aimed at the development of metacognition in patients with AN.<\/jats:p>","DOI":"10.17816\/cp15736","type":"journal-article","created":{"date-parts":[[2025,12,18]],"date-time":"2025-12-18T17:41:24Z","timestamp":1766079684000},"page":"24-34","update-policy":"https:\/\/doi.org\/10.17816\/crossmarkpolicy2018","source":"Crossref","is-referenced-by-count":0,"title":["Moderating effect of metacognition on the relationship between perfectionism, body image disturbance, and body mass index in anorexia nervosa: a cross-sectional study"],"prefix":"10.17816","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5347-0231","authenticated-orcid":false,"given":"Nikita V.","family":"Chernov","sequence":"additional","affiliation":[{"name":"Mental-health clinic No. 1 named after N.A.
