Research has demonstrated mentalizing impairment associated with borderline personality disorder (BPD) in adolescents. However, mentalizing performance in adolescents with BPD has never been compared to that of psychiatric control and healthy control adolescents simultaneously. The present study aimed to (a) compare implicit and explicit mentalizing, and hypermentalizing errors in implicit mentalizing, across youth with BPD and psychiatric and healthy controls, and (b) evaluate the association of borderline features with mentalizing deficits over and above internalizing and externalizing. Psychiatric inpatients with BPD (n = 139), inpatient psychiatric controls (n = 310), and healthy adolescents (n = 134) completed two mentalizing tasks, an interview assessing BPD, and measures of psychopathology. Results showed that BPD specificity could be demonstrated only for implicit mentalizing and hypermentalizing. Explicit mentalizing deficits did not differ between BPD and psychiatric control groups. Borderline features had unique associations to implicit mentalizing and hypermentalizing, over and above internalizing and externalizing.

青少年住院患者的内隐和外显心理缺陷：临界病理学的特异性和增量价值

研究表明，青少年边缘性人格障碍 (BPD) 存在心理化障碍。然而，从未将患有 BPD 的青少年的心理化表现与精神病控制和健康控制青少年同时进行比较。本研究旨在（a）比较内隐和外显心理化以及内隐心理化中的过度心理化错误，在患有 BPD 和精神病学和健康对照的青年中，以及（b）评估边缘特征与心理化缺陷的关联，而不是内化和外化. 患有 BPD 的精神病住院患者 (n = 139)、住院精神病对照者 (n = 310) 和健康青少年 (n = 134) 完成了两项心理化任务、评估 BPD 的访谈和精神病理学测量。结果表明，BPD 特异性只能在隐性心理化和过度心理化中得到证实。BPD 和精神科对照组之间的显性心理化缺陷没有差异。边缘特征与内隐心理化和超心理化有着独特的关联，超越了内化和外化。
