Facial emotion recognition (FER) is essential to guide social functioning and behaviour for interpersonal communication. FER may be altered in severe mental illness such as in psychosis and in borderline personality disorder patients. However, it is unclear if these FER alterations are specifically related to psychosis. Awareness of FER alterations may be useful in clinical settings to improve treatment strategies. The aim of our study was to examine FER in patients with severe mental disorder and their relation with psychotic symptomatology.
Socio-demographic and clinical variables were collected. Alterations on emotion recognition were assessed in 3 groups: patients with first episode psychosis (FEP) (n = 64), borderline personality patients (BPD) (n = 37) and healthy controls (n = 137), using the Degraded Facial Affect Recognition Task. The Positive and Negative Syndrome Scale, Structured Interview for Schizotypy Revised and Community Assessment of Psychic Experiences scales were used to assess positive psychotic symptoms. WAIS III subtests were used to assess IQ.
Kruskal-Wallis analysis showed a significant difference between groups on the FER of neutral faces score between FEP, BPD patients and controls and between FEP patients and controls in angry face recognition. No significant differences were found between groups in the fear or happy conditions. There was a significant difference between groups in the attribution of negative emotion to happy faces. BPD and FEP groups had a much higher tendency to recognize happy faces as negatives. There was no association with the different symptom domains in either group.
FEP and BPD patients have problems in recognizing neutral faces more frequently than controls. Moreover, patients tend to over-report negative emotions in recognition of happy faces. Although no relation between psychotic symptoms and FER alterations was found, these deficits could contribute to a patient's misinterpretations in daily life.
面部情绪识别（FER）对于指导人际沟通中的社交功能和行为至关重要。在严重精神疾病如精神病和边缘型人格障碍患者中，FER可能会发生改变。然而，目前尚不清楚这些FER改变是否与精神病有特定关联。了解FER改变在临床环境中可能有助于改善治疗策略。我们研究的目的是检查严重精神障碍患者的FER及其与精神病症状学的关系。
收集社会人口统计学和临床变量。使用退化面部表情识别任务，对3组人群进行情绪识别改变评估：首发精神病（FEP）患者（n = 64）、边缘型人格障碍患者（BPD）（n = 37）和健康对照者（n = 137）。使用阳性和阴性症状量表、精神分裂症型人格修订结构化访谈量表以及心理体验社区评估量表来评估阳性精神病症状。使用韦氏成人智力量表第三版（WAIS III）子测验来评估智商。
Kruskal-Wallis分析显示，FEP患者、BPD患者与对照者在中性面孔FER得分上存在显著差异，FEP患者与对照者在愤怒面孔识别上也存在显著差异。在恐惧或高兴表情条件下，各组之间未发现显著差异。在将负面情绪归因于高兴面孔方面，各组之间存在显著差异。BPD组和FEP组将高兴面孔识别为负面的倾向要高得多。两组中均未发现与不同症状领域存在关联。
FEP患者和BPD患者比对照者更频繁地在识别中性面孔方面存在问题。此外，患者在识别高兴面孔时倾向于过度报告负面情绪。虽然未发现精神病症状与FER改变之间存在关联，但这些缺陷可能导致患者在日常生活中产生误解。
