Therefore, the aim of this study was to examine its psychometric properties in a large clinical sample of adolescent and adult inpatients with anorexia nervosa and bulimia nervosa.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>A sample of 2,535 German female inpatients with EDs completed the CET and other instruments at admission and discharge. Factor structure (confirmatory [CFA] and exploratory factor analyses [EFA]), internal consistency and construct validity, measurement invariance across age and diagnostic groups, group comparisons of means, as well as sensitivity to change during treatment were assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The CET showed high internal consistency, very good construct validity, and sensitivity to change. CFA indicated a better fit of four\u2010factor and three\u2010factor solutions compared to the original five\u2010factor model. However, subsequent EFA identified an optimum for a five\u2010factor model. Only three subscales were satisfactorily invariant to measurement, but not the CET total score. Only small differences in scores between patient groups were observed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Results support internal consistency, construct validity, and sensitivity to change, whereas factor structure remains inconclusive, questioning the theoretical basis of the CET. There is limited support for using the lack of enjoyment subscale, and only moderate support for using the rigidity subscale in patients with EDs. It is recommended to further explore and\/or revise the original CET, including investigation in other samples, for example, male samples.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.23694","type":"journal-article","created":{"date-parts":[[2022,2,24]],"date-time":"2022-02-24T05:04:04Z","timestamp":1645679044000},"page":"494-504","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Psychometric properties of the Compulsive Exercise Test in a large sample of female adolescent and adult inpatients with anorexia nervosa and bulimia nervosa"],"prefix":"10.1002","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1791-7379","authenticated-orcid":false,"given":"Sandra","family":"Schlegl","sequence":"first","affiliation":[{"name":"Department of Psychiatry and Psychotherapy University Hospital, Ludwig\u2010Maximilians\u2010University (LMU)  Munich Germany"},{"name":"Schoen Clinic Roseneck  Prien am Chiemsee Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Larissa","family":"Vierl","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy University Hospital, Ludwig\u2010Maximilians\u2010University (LMU)  Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8649-5467","authenticated-orcid":false,"given":"David R.","family":"Kolar","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy University Hospital, Ludwig\u2010Maximilians\u2010University (LMU)  Munich Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"Dittmer","sequence":"additional","affiliation":[{"name":"Schoen Clinic Roseneck  Prien am Chiemsee Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrich","family":"Voderholzer","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Psychotherapy University Hospital, Ludwig\u2010Maximilians\u2010University (LMU)  Munich Germany"},{"name":"Schoen Clinic Roseneck  Prien am Chiemsee Germany"},{"name":"Department of Psychiatry and Psychotherapy University Hospital  Freiburg Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,2,23]]},"reference":[{"key":"e_1_2_9_2_1","volume-title":"Amos (version 26.0) [computer program]","author":"Arbuckle J.
