Epistemic distrust \u2013 resulting from early adversity \u2013 may interfere with openness to social learning within the therapeutic encounter, reducing the ability to benefit from treatment. The self\u2010report Questionnaire Epistemic Trust (QET) is a newly developed instrument that aims to assess ET. This study presents the first results on the psychometric properties of the QET in both a community and a clinical sample. Our findings indicate that the QET is composed of four meaningful subscales with good to excellent internal consistency. The QET shows relevant associations with related constructs like personality functioning, symptom distress and quality of life. QET scores clearly distinguish between a clinical and community sample and are associated with the quality of the therapeutic alliance. The QET provides a promising, brief and user\u2010friendly instrument that could be used for a range of clinical and research purposes. Future studies with larger samples are needed to strengthen construct validity and to investigate the value of the QET to predict differential treatment responses or to study mechanisms of change.<\/jats:p>","DOI":"10.1002\/cpp.2930","type":"journal-article","created":{"date-parts":[[2023,11,10]],"date-time":"2023-11-10T09:35:31Z","timestamp":1699608931000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The development and psychometric evaluation of the Questionnaire Epistemic Trust (QET): A self\u2010report assessment of epistemic trust"],"prefix":"10.1002","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9607-1265","authenticated-orcid":false,"given":"Saskia","family":"Knapen","sequence":"first","affiliation":[{"name":"Altrecht Mental Health Care, Utrecht Amsterdam UMC  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilma E.","family":"Swildens","sequence":"additional","affiliation":[{"name":"Altrecht Mental Health Care, Utrecht Inholland University of Applied Sciences  Amsterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wendy","family":"Mensink","sequence":"additional","affiliation":[{"name":"Altrecht Mental Health Care  Utrecht The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriaan","family":"Hoogendoorn","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Amsterdam Public Health Research Institute Amsterdam University Medical Center  Amsterdam the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joost","family":"Hutsebaut","sequence":"additional","affiliation":[{"name":"Tilburg University and Viersprong Institute for the Study on Personality Disorders  Halsteren The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aartjan T.
