Evidence suggests that narcissism and borderline personality disorder are associated with each other. This naturalistic study investigated the predictive value of grandiose and vulnerable narcissism on the development of the therapeutic alliance in short-term psychodynamic treatment across 12 weeks. The sample consisted of 99 patients with borderline personality disorder. Narcissism was assessed with the Pathological Narcissism Inventory at treatment onset. The therapeutic alliance was rated with the Scale to Assess Therapeutic Relationships by both patient and therapist at four time points during treatment. Results showed a significant predictive value of vulnerable narcissism on the therapeutic alliance, revealing a more beneficial progression for patients with higher vulnerable narcissism. Grandiose narcissism had no predictive value on the therapeutic alliance. The study strengthens the clinical utility of the concept of vulnerable narcissism towards the evaluation of treatment processes in borderline personality disorder.

脆弱的自恋是边缘型人格障碍治疗联盟的有益因素

有证据表明，自恋和边缘型人格障碍相互关联。这项自然主义研究调查了夸大和脆弱的自恋对 12 周短期心理动力学治疗中治疗联盟发展的预测价值。样本由 99 名边缘型人格障碍患者组成。在治疗开始时使用病理自恋量表评估自恋。治疗联盟在治疗期间的四个时间点由患者和治疗师根据治疗关系评估量表进行评级。结果表明，脆弱自恋对治疗联盟具有显着的预测价值，揭示了脆弱自恋程度较高的患者更有益的进展。夸大的自恋对治疗联盟没有预测价值。该研究加强了脆弱自恋概念在评估边缘型人格障碍治疗过程中的临床效用。
