The cross-sectional, nationally representative, and publicly available data were extracted from the 2014 Health Center Patient Survey (HCPS), which was sponsored by the Health Resources and Services Administration (HRSA). After excluding certain individuals for the purpose of this study, we had a total of 1,863 participants. The highest and lowest psychological distress weighted scores were reported by individuals with bipolar disorder ( M = 17.16) and individuals with schizophrenia ( M = 16.09), respectively, although psychological distress interference was highest in individuals with schizophrenia ( M = 2.44). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) results yielded a unidimensional factor solution for K6 scale in all subgroups. The K6 is a brief, reliable, and valid measure of psychological distress in adults with panic disorder, generalized anxiety disorder, bipolar disorder, and schizophrenia.<\/jats:p>","DOI":"10.1177\/00343552211043261","type":"journal-article","created":{"date-parts":[[2021,9,3]],"date-time":"2021-09-03T12:29:07Z","timestamp":1630672147000},"page":"140-149","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":86,"title":["A National Study to Assess Validity and Psychometrics of the Short Kessler Psychological Distress Scale (K6)"],"prefix":"10.1177","volume":"65","author":[{"given":"Emre","family":"Umucu","sequence":"first","affiliation":[{"name":"Michigan State University, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Fortuna","sequence":"additional","affiliation":[{"name":"Dartmouth College, Hanover, NH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyejin","family":"Jung","sequence":"additional","affiliation":[{"name":"The University of Texas at El Paso, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anita","family":"Bialunska","sequence":"additional","affiliation":[{"name":"The University of Texas at El Paso, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6438-7377","authenticated-orcid":false,"given":"Beatrice","family":"Lee","sequence":"additional","affiliation":[{"name":"Michigan State University, USA"},{"name":"The University of Texas at El Paso, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thenral","family":"Mangadu","sequence":"additional","affiliation":[{"name":"The University of Texas at El Paso, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1139-5947","authenticated-orcid":false,"given":"Marianne","family":"Storm","sequence":"additional","affiliation":[{"name":"University of Stavanger, Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gul","family":"Ergun","sequence":"additional","affiliation":[{"name":"Burdur Mehmet Akif Ersoy University, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donyeill A.","family":"Mozer","sequence":"additional","affiliation":[{"name":"The University of Texas at El Paso, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Brooks","sequence":"additional","affiliation":[{"name":"University of Wisconsin-Madison, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,9,3]]},"reference":[{"key":"bibr1-00343552211043261","doi-asserted-by":"crossref","unstructured":"Arnaud B., Malet L., Teissedre F., Izaute M., Moustafa F., Geneste J., Schmidt J., Llorca P.M., Brousse G.
