Patients with borderline personality disorder (BPD) exhibit impairment in labeling of facial emotional expressions. However, it is not clear whether these deficits affect the whole domain of basic emotions, are valence-specific, or specific to individual emotions. Whether BPD patients' errors in a facial emotion recognition task create a specific pattern also remains to be elucidated. Our study tested two hypotheses: first, we hypothesized, that the emotion perception impairment in borderline personality disorder is specific to the negative emotion domain. Second, we hypothesized, that BPD patients would show error patterns in a facial emotion recognition task more commonly and more systematically than healthy comparison subjects. Participants comprised 33 inpatients with BPD and 32 matched healthy control subjects who performed a computerized version of the Ekman 60 Faces test. The indices of emotion recognition and the direction of errors were processed in separate analyses. Clinical symptoms and personality functioning were assessed using the Symptom Checklist-90-Revised and the Young Schema Questionnaire Long Form. Results showed that patients with BPD were less accurate than control participants in emotion recognition, in particular, in the discrimination of negative emotions, while they were not impaired in the recognition of happy facial expressions. In addition, patients over-attributed disgust and surprise and under-attributed fear to the facial expressions relative to controls. These findings suggest the importance of carefully considering error patterns, besides measuring recognition accuracy, especially among emotions with negative affective valence, when assessing facial affect recognition in BPD.
边缘型人格障碍(BPD)患者在面部情绪表达的标签识别上存在障碍。然而,这些缺陷是否影响基本情绪的整个领域,是效价特异性的,还是特定于个别情绪,尚不清楚。BPD 患者在面部情绪识别任务中的错误是否会形成特定模式,也有待阐明。我们的研究检验了两个假设:首先,我们假设,边缘型人格障碍的情绪感知障碍是特定于负性情绪领域的。其次,我们假设,BPD 患者在面部情绪识别任务中的错误模式会比健康对照组更常见且更系统。参与者包括 33 名边缘型人格障碍住院患者和 32 名匹配的健康对照组,他们在计算机版的 Ekman 60 张面孔测试中进行了测试。情绪识别的指标和错误的方向在单独的分析中进行处理。使用症状清单-90 修订版和年轻模式问卷长式评估临床症状和人格功能。结果表明,BPD 患者在情绪识别方面的准确性低于对照组,特别是在识别负性情绪方面,而在识别愉快的面部表情方面则没有受损。此外,与对照组相比,患者将厌恶和惊讶的表情归因于面部表情的频率过高,而将恐惧的表情归因于面部表情的频率过低。这些发现表明,在评估 BPD 中的面部情感识别时,除了测量识别准确性之外,还需要仔细考虑错误模式,尤其是在评估具有负性情感效价的情绪时。
