This study examined self-reported personality functioning among patients with SUD compared to the general population, gender specifics, and the psychometric properties of the Czech Level of Personality Functioning Scale-Self Report (LPFS-SR). Methods: Two samples were used in this study. Sample 1 (n = 368) consisted of patients with SUD, while Sample 2 (n = 497) comprised volunteers from the general population. All participants, with an age range of 18\u201375 years, completed a battery of self-assessment tools, including a demographic form, the Personality Inventory for DSM-5 (PID-5), and the LPFS-SR, administered via a pencil-and-paper method. Internal consistency and several aspects of the validity of the Czech LPFS-SR were examined. Results: The LPFS-SR showed high internal consistency as estimated by Cronbach\u2019s alpha (\u03b1 \u2265 0.66) and the high mutual correlation with the PID-5 varied from 0.21 to 0.77. Principal component analysis (PCA) of the four LPFS-SR subscales indicated a single-component structure, accounting for 78.21% of the variance in Sample 1 and 79.20% in Sample 2, supporting previous results regarding the LPFS-SR factorial structure. Furthermore, gender-specific cut-off scores were obtained and are discussed in relation to previous research. Conclusion: The findings indicate that the Czech LPFS-SR is a valid and reliable tool with acceptable discriminating capacity. It can be used in research and clinical assessments of personality functioning in patients with SUD, particularly when considering gender-specific characteristics.<\/jats:p>","DOI":"10.31083\/ap46058","type":"journal-article","created":{"date-parts":[[2025,9,10]],"date-time":"2025-09-10T00:39:03Z","timestamp":1757464743000},"source":"Crossref","is-referenced-by-count":1,"title":["Self-Reported Personality Functioning in Patients With Substance Use Disorders: Similarities and Specifics With Respect to the Czech Community Sample"],"prefix":"10.31083","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-2597-836X","authenticated-orcid":true,"given":"Lucia","family":"Schlosserova","sequence":"first","affiliation":[{"name":"Department of Addictology, 1st Faculty of Medicine, Charles University and General University Hospital in Prague, 128 00 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9881-8731","authenticated-orcid":true,"given":"Livia","family":"Rosova","sequence":"first","affiliation":[{"name":"Department of Applied Mathematics and Statistics, Faculty of Mathematics, Physics and Informatics, Comenius University, 842 48 Bratislava, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8640-2734","authenticated-orcid":true,"given":"Tadeas S.","family":"Zbornik","sequence":"first","affiliation":[{"name":"Department of Addictology, 1st Faculty of Medicine, Charles University and General University Hospital in Prague, 128 00 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2035-2428","authenticated-orcid":true,"given":"Karel D.","family":"Riegel","sequence":"first","affiliation":[{"name":"Department of Addictology, 1st Faculty of Medicine, Charles University and General University Hospital in Prague, 128 00 Prague, Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2025,8,26]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Verheul R, Kranzler HR, Poling J, Tennen H, Ball S, Rounsaville BJ.
