Self-perception is disrupted in people with borderline personality disorder (BPD) and depersonalization disorder (DPD), fluctuating with sudden shifts in affect in BPD and experienced as detached in DPD. Measures of implicit self-esteem (ISE), free from conscious control and presentation biases, may highlight how such disruptions of self-concept differentially affect these two populations on an unconscious level. We examined ISE using the Implicit Association Test, along with measures of emotion, behavior, and temperament, in BPD (n = 18), DPD (n = 18), and healthy control (n = 35) participants. DPD participants had significantly higher ISE and were more harm avoidant than BPD and control participants, while BPD participants had more "frontal" behaviors and impulsivity and less self-directedness and cooperativeness than DPD and control participants. Thus, while BPD and DPD commonly overlap in terms of dissociative symptoms and emotional irregularities, differences in self-esteem, behavior, and temperament can help identify where they diverge in terms of their cognition, behavior, and ultimately underlying neurobiology.
边缘型人格障碍（BPD）和人格解体障碍（DPD）患者的自我认知受到干扰，在BPD中随情绪的突然变化而波动，在DPD中则表现为脱离感。内隐自尊（ISE）测量不受意识控制和呈现偏差的影响，可能会揭示这种自我概念的干扰如何在无意识层面上对这两个人群产生不同影响。我们使用内隐联想测验对BPD（n = 18）、DPD（n = 18）和健康对照（n = 35）参与者进行了ISE测试，并同时测量了他们的情绪、行为和气质。DPD参与者的ISE显著高于BPD和对照参与者，且比他们更回避伤害，而BPD参与者比DPD和对照参与者有更多的“额叶”行为和冲动性，自我导向性和合作性则更低。因此，虽然BPD和DPD在解离症状和情绪异常方面通常有重叠，但自尊、行为和气质方面的差异有助于确定它们在认知、行为以及最终潜在神经生物学方面的不同之处。
