A total of 814 individuals participated, including a sine morbo (SM; Latin for \u201cwithout any disease\u201d; here specifically \u201cwithout any mental disorder\u201d) subsample (n = 509), a clinical subsample without personality disorder (non-PD; n = 240), and a clinical subsample with personality disorder (PD; n = 65). Significant differences were found among the subsamples on all LPFS-BF 2.0 scores, with the PD subsample showing the most severe impairments, followed by the non-PD and SM subsamples. To determine cutoff scores, ROC curve analyses were conducted on 70% of the data (training set, randomly selected) and validated on the remaining set of the data (test set), controlling for age, sex, and level of education. The accuracy of the LPFS-BF 2.0 in discriminating between all three subsamples was demonstrated.<\/jats:p>","DOI":"10.1521\/pedi.2026.40.1.33","type":"journal-article","created":{"date-parts":[[2026,2,17]],"date-time":"2026-02-17T15:16:42Z","timestamp":1771341402000},"page":"33-47","source":"Crossref","is-referenced-by-count":1,"title":["Screening for Personality Disorders Using the Level of Personality Functioning: Diagnostic Accuracy of the LPFS-BF 2.0 in Clinical and\n                    <i>Sine Morbo<\/i>\n                    Samples"],"prefix":"10.1521","volume":"40","author":[{"given":"B\u00e9la","family":"Birk\u00e1s","sequence":"first","affiliation":[{"name":"Institute of Behavioral Sciences, Medical School, University of P\u00e9cs, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e1s Norbert","family":"Zsid\u00f3","sequence":"additional","affiliation":[{"name":"Institute of Psychology, Faculty of Humanities and Social Sciences, University of P\u00e9cs, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e1ra","family":"Gergely","sequence":"additional","affiliation":[{"name":"VIKOTE Center for Cognitive and Schema Therapy, Budapest, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regina","family":"T\u00f3th","sequence":"additional","affiliation":[{"name":"VIKOTE Center for Cognitive and Schema Therapy, Budapest, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00falia","family":"Andr\u00f3czi","sequence":"additional","affiliation":[{"name":"VIKOTE Center for Cognitive and Schema Therapy, Budapest, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tibor Cece","family":"Kiss","sequence":"additional","affiliation":[{"name":"Doctoral School of Psychology, University of P\u00e9cs, Faculty of Humanities and Social Sciences, P\u00e9cs, Hungary, and Department of Psychosomatic and Psychotherapeutic Rehabilitation \u201cT\u00fcnd\u00e9rhegy,\u201d Semmelweis University, Rehabilitation Clinic (SERK), Budapest, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gy\u00f6rgy Zsolt","family":"Rubovszky","sequence":"additional","affiliation":[{"name":"Doctoral School of Psychology, Faculty of Education and Psychology, E\u00f6tv\u00f6s Lor\u00e1nd University (ELTE PPK), Budapest, Hungary."},{"name":"Kairosz Psychotherapy Clinic"},{"name":"Family Centered Buda Mental Health Center (Psychiatry), Saint John's Central Hospital, Budapest, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00f3zsa Vivien","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"Doctoral School of Psychology, Faculty of Education and Psychology, E\u00f6tv\u00f6s Lor\u00e1nd University (ELTE PPK), Budapest, Hungary."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zsolt","family":"Demetrovics","sequence":"additional","affiliation":[{"name":"Flinders University Institute for Mental Health and Wellbeing, College of Education, Psychology and Social Work, Flinders University, Bedford Park, Australia;
