This study examines psychopathology and clinical characteristics of patients with borderline personality disorder (BPD) and comorbid narcissistic personality disorder (NPD) from two international randomized controlled trials. From a combined sample of 188 patients with BPD, 25 also fulfilled criteria for a comorbid diagnosis of NPD according to DSM-IV. The BPD patients with comorbid NPD, compared to the BPD patients without comorbid NPD, showed significantly more BPD criteria (M = 7.44 vs. M = 6.55, p < .001), fulfilled more criteria of comorbid histrionic (M = 3.84 vs. M = 1.98, p < .001), paranoid (M = 3.12 vs. M = 2.27, p = .014), and schizotypal (M = 1.64 vs. M = 1.02, p = .018) personality disorders, and were more likely to meet criteria for full histrionic PD diagnosis (44.0% vs. 14.2%, p < .001). The BPD-NPD group also reported significantly fewer psychiatric hospitalizations in the previous year (M = 0.40 vs. M = 0.82, p = .019) and fewer axis I disorders (M = 2.68 vs. M = 3.75, p = .033). No differences could be found in general functioning, self-harming behavior, and suicide attempts.
本研究从两项国际随机对照试验中考察了伴发自恋型人格障碍(NPD)的边缘型人格障碍(BPD)患者的精神病理学和临床特征。在 188 名 BPD 患者的合并样本中,有 25 名患者根据 DSM-IV 标准也符合伴发 NPD 的诊断。与不伴发 NPD 的 BPD 患者相比,伴发 NPD 的 BPD 患者表现出更多的 BPD 标准(M = 7.44 对 M = 6.55,p <.001),符合更多伴发的癔症型(M = 3.84 对 M = 1.98,p <.001)、偏执型(M = 3.12 对 M = 2.27,p =.014)和分裂样型(M = 1.64 对 M = 1.02,p =.018)人格障碍标准,更有可能符合完全癔症型 PD 的诊断标准(44.0%对 14.2%,p <.001)。BPD-NPD 组在前一年的住院治疗次数(M = 0.40 对 M = 0.82,p =.019)和 I 轴障碍(M = 2.68 对 M = 3.75,p =.033)也显著减少。在一般功能、自残行为和自杀企图方面未发现差异。
