Consequently, most PD research is centered on cluster B PDs (especially borderline PD). Yet, prevalence ratings of cluster C PDs exceed those of cluster B PDs. In this explorative, cross-sectional study, we compared cluster B and C PD patients (N = 94) on a wide range of clinically-relevant severity measures, including comorbidity, suicidality, (childhood) traumatization and global functioning. Results showed that, although cluster B PD patients suffered more often from substance use disorders and lifetime suicide attempts, no difference could be established between groups for all other severity measures, including trauma variables. In our study, we additionally included a group of combined cluster B and C PDs, who were largely similar to both other groups. Although our study is insufficiently powered to claim a significant non-difference, these findings emphasize that high rates of comorbidity, suicidality, childhood traumatization and functional impairment apply to both cluster B and C patients. As such, our findings encourage more research into cluster C PDs, ultimately leading to more evidence-based treatments for this prevalent patient group. In addition, the high level of traumatization across groups calls for a routine trauma screening, especially since PD treatment may benefit from concurrent trauma treatment.<\/jats:p>","DOI":"10.3390\/bs12040105","type":"journal-article","created":{"date-parts":[[2022,4,12]],"date-time":"2022-04-12T02:48:59Z","timestamp":1649731739000},"page":"105","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Cluster B versus Cluster C Personality Disorders: A Comparison of Comorbidity, Suicidality, Traumatization and Global Functioning"],"prefix":"10.3390","volume":"12","author":[{"given":"Laura Y.","family":"Massaal-van der Ree","sequence":"first","affiliation":[{"name":"GGZ in Geest Mental Health Care, 1081 HJ Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merijn","family":"Eikelenboom","sequence":"additional","affiliation":[{"name":"GGZ in Geest Mental Health Care, 1081 HJ Amsterdam, The Netherlands"},{"name":"Department of Psychiatry, Amsterdam UMC Location Vrije Universiteit Amsterdam, Boelelaan 1117, 1007 MB Amsterdam, The Netherlands"},{"name":"Amsterdam Public Health, Mental Health Program, 1007 MB Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriaan W.","family":"Hoogendoorn","sequence":"additional","affiliation":[{"name":"GGZ in Geest Mental Health Care, 1081 HJ Amsterdam, The Netherlands"},{"name":"Department of Psychiatry, Amsterdam UMC Location Vrije Universiteit Amsterdam, Boelelaan 1117, 1007 MB Amsterdam, The Netherlands"},{"name":"Amsterdam Public Health, Mental Health Program, 1007 MB Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathleen","family":"Thomaes","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, Amsterdam UMC Location Vrije Universiteit Amsterdam, Boelelaan 1117, 1007 MB Amsterdam, The Netherlands"},{"name":"Sinai Centrum, Arkin Institute for Mental Health, 1033 NN Amsterdam, The Netherlands"},{"name":"Amsterdam Neuroscience, Mood, Anxiety, Psychosis, Stress & Sleep Program, 1007 MB Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hein J.
