The SDQ-20 evaluates the severity of somatoform dissociative phenomena, and the SDQ-5 is a dissociative disorders screening instrument. &lt;b&gt;Methods:&lt;\/b&gt; Thirty-one patients with dissociative disorders and 45 consecutive psychiatric outpatients with other DSM-IV diagnoses completed the SDQ-20 and SDQ-5 as well as the Dissociation Questionnaire which measures psychological dissociation. &lt;b&gt;Results:&lt;\/b&gt; Mokken scale analysis showed that the items of the SDQ-20 are strongly scalable on a latent unidimensional scale. Internal consistency was high. The SDQ-20 convergent validity was supported by high intercorrelations with the DIS-Q. Dissociative patients obtained significantly higher scores than comparison patients. Patients with dissociative identity disorder scored significantly higher compared to patients with dissociative disorder nos. Sensitivity (94%) and specificity (98%) of the SDQ-5 were very satisfactory, as were, at an estimated prevalence rate of dissociative disorders of 10% among psychiatric patients, positive predictive value (84%) and negative predictive value (99%). &lt;b&gt;Conclusions:&lt;\/b&gt; All results replicated the first findings, and therefore corroborate the conclusion that the SDQ-20 and SDQ-5 are instruments of sound psychometric quality, and that somatoform dissociative phenomena are core symptoms of complex dissociative disorders.<\/jats:p>","DOI":"10.1159\/000012254","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T15:43:24Z","timestamp":1050421404000},"page":"17-23","source":"Crossref","is-referenced-by-count":98,"title":["Psychometric Characteristics of the Somatoform Dissociation Questionnaire: A Replication Study&lt;footref rid=\"foot01\"&gt;&lt;sup&gt;1&lt;\/sup&gt;&lt;\/footref&gt;"],"prefix":"10.1159","volume":"67","author":[{"given":"Ellert R.S.","family":"Nijenhuis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philip","family":"Spinhoven","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"van Dyck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Onno","family":"van der Hart","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johan","family":"Vanderlinden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[1998,1,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/00005053-199611000-00006"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1037\/\/1082-989X.1.3.300"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/0163-8343(94)00058-L"}],"container-title":["Psychotherapy and Psychosomatics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/12254","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/12254","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:57:42Z","timestamp":1745470662000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000012254"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998]]},"references-count":3,"journal-issue":{"issue":"1","published-online":{"date-parts":[[1998,2,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000012254","archive":["Portico"],"relation":{},"ISSN":["0033-3190","1423-0348"],"issn-type":[{"value":"0033-3190","type":"print"},{"value":"1423-0348","type":"electronic"}],"subject":[],"published":{"date-parts":[[1998]]}}}
