The correlations between the BPDCL and other instruments, used in the studies, were weak to strong. Correlations greater than 0.55 were observed between the BPDCL and the scales BPDSI, SCL-90 and the BSI. In addition, the BPDCL seems to differentiate well between diagnostic groups. BPD patients scored the highest, followed by patients with other personality disorders, who in turn scored higher than Axis I disorder patients and healthy controls.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>In general, the BPDCL possesses good psychometric properties and seems to be an adequate self-report instrument to measure the subjective burden of BPD patients.</p>\u0000 </section>\u0000 </div>","PeriodicalId":50310,"journal":{"name":"International Journal of Methods in Psychiatric Research","volume":"34 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mpr.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
