This article reports the development and factorial validation of a short version of a narcissism inventory. &lt;i&gt;Sampling and Methods:&lt;\/i&gt; The sample includes data of 4,509 consecutive psychosomatic inpatients. The overall sample was divided in 2 equally sized randomized subsamples. One sample (n = 2,262) was used for exploratory factor analysis (principal component analysis). The other sample (n = 2,265) was used for confirmatory tests of the model fit of the newly built NI-20 version, and to analyze the model fit separately for men and women using structural equation modeling with AMOS software. &lt;i&gt;Results:&lt;\/i&gt; The short version (NI-20) consists of 20 items, with items representing almost all of the original 18 subscales and 4 second-order dimensions. The NI-20 possesses properties similar to the NI-90, with a considerable gain in test economy. The 4-factor structure of the NI-20 was confirmed, and reaches good fit indices. &lt;i&gt;Conclusions:&lt;\/i&gt; The NI-20 is an economical instrument with acceptable psychometric characteristics that reflects the heterogeneous aspects of narcissism. A methodological limitation is that the interactions between sociodemographic variables were not included as potential predictors.<\/jats:p>","DOI":"10.1159\/000288636","type":"journal-article","created":{"date-parts":[[2010,3,1]],"date-time":"2010-03-01T09:20:08Z","timestamp":1267435208000},"page":"150-158","source":"Crossref","is-referenced-by-count":8,"title":["Development and Factorial Validation of a Short Version of the Narcissism Inventory (NI-20)"],"prefix":"10.1159","volume":"43","author":[{"given":"I.","family":"Daig","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Burkert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.F.","family":"Fischer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Kienast","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.F.","family":"Klapp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Fliege","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2010,2,27]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1207%2Fs15327752jpa4803_11"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2006-951922"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1037%2F0022-3514.61.4.590"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1177%2F000306517001800403"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1037%2Fh0079120"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.adolescence.2005.01.008"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1006%2Fjrpe.1997.2204"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1037%2F0022-3514.87.3.400"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2000-9095"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2FS0191-8869%2898%2900251-7"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1159%2F000069073"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1159%2F000029114"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1080%2F10705519909540118"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1108%2F13522750010322070"}],"container-title":["Psychopathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/288636","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/288636","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T19:49:41Z","timestamp":1745437781000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000288636"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":14,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2010,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000288636","archive":["Portico"],"relation":{},"ISSN":["0254-4962","1423-033X"],"issn-type":[{"value":"0254-4962","type":"print"},{"value":"1423-033X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010]]}}}
