Very few studies have focused on the relationship between cognitive functions and clinical features in borderline personality disorder (BPD). Subjects with BPD and healthy controls were administered the Repeatable Battery for the Assessment of Neuropsychological Status, Trail Making Test A and B, and the Wisconsin Card Sorting Test. The Brief Symptom Inventory (BSI-53) was used to assess the severity of current symptoms. Attachment style was assessed with the Experiences in Close Relationship Questionnaire, identity integration with the Personality Structure Questionnaire, and other domains of personality dysfunction with the RUDE Scale for Personality Dysfunction. Patients with BPD performed significantly worse than healthy controls in all cognitive domains. Cognitive functions, particularly delayed memory and visuospatial abilities, displayed meaningful associations with trait-like clinical features, above the effect of global cognition and state psychopathology. These findings highlight the need to evaluate effects of cognitive rehabilitation on trait features among individuals with BPD.

边缘型人格障碍患者认知能力与特质临床特征的关系。

很少有研究关注边缘型人格障碍 (BPD) 的认知功能与临床特征之间的关系。患有 BPD 和健康对照的受试者接受了用于神经心理状态评估的可重复电池组、线索制作测试 A 和 B 以及威斯康星卡片分类测试。简要症状量表 (BSI-53) 用于评估当前症状的严重程度。依恋风格通过亲密关系经历问卷、人格结构问卷的身份整合以及其他人格障碍领域的 RUDE 人格障碍量表进行评估。BPD 患者在所有认知领域的表现都明显低于健康对照组。认知功能，特别是延迟记忆和视觉空间能力，表现出与特质样临床特征的有意义的关联，高于整体认知和状态精神病理学的影响。这些发现强调需要评估认知康复对 BPD 个体特征特征的影响。
