Patients with borderline personality disorder (BPD) show negative and unstable self- and other-evaluations compared to healthy individuals. It is unclear, however, how they process self- and other-relevant social feedback. We have previously demonstrated a positive updating bias in healthy individuals: When receiving social feedback on character traits, healthy individuals integrate desirable more than undesirable feedback. Here, our aim was to test whether BPD patients exhibit a more negative pattern of social feedback processing.
We employed a character trait task in which BPD patients interacted with four healthy participants in a real-life social interaction. Afterwards, all participants rated themselves and one other participant on 80 character traits before and after receiving feedback from their interaction partners. We compared how participants updated their ratings after receiving desirable and undesirable feedback. Our analyses included 22 BPD patients and 81 healthy controls.
Healthy controls showed a positivity bias for self- and other-relevant feedback as previously demonstrated. Importantly, this pattern was altered in BPD patients: They integrated undesirable feedback for themselves to a greater degree than healthy controls did. Other-relevant feedback processing was unaltered in BPD patients.
Our study demonstrates an alteration in self-relevant feedback processing in BPD patients that might contribute to unstable and negative self-evaluations.
与健康个体相比，边缘型人格障碍（BPD）患者表现出消极且不稳定的自我和他人评价。然而，尚不清楚他们如何处理与自我和他人相关的社会反馈。我们之前已证明健康个体存在积极的更新偏差：在收到关于性格特质的社会反馈时，健康个体整合期望反馈比不期望反馈更多。在此，我们的目的是测试BPD患者是否表现出更消极的社会反馈处理模式。
我们采用了一项性格特质任务，其中BPD患者在现实生活中的社交互动中与四名健康参与者进行互动。之后，所有参与者在从互动伙伴那里收到反馈之前和之后，就80种性格特质对自己和另一名参与者进行评分。我们比较了参与者在收到期望和不期望反馈后如何更新他们的评分。我们的分析纳入了22名BPD患者和81名健康对照者。
如先前所示，健康对照者对与自我和他人相关的反馈表现出积极偏差。重要的是，这种模式在BPD患者中发生了改变：他们比健康对照者更大程度地整合了对自己的不期望反馈。BPD患者对与他人相关的反馈处理未发生改变。
我们的研究表明BPD患者与自我相关的反馈处理存在改变，这可能导致不稳定和消极的自我评价。
