目的：本研究的目的是探讨青年人在不同阶段的精神病sills.Methods：79个超高危患者，30例首发精神分裂症患者和30名健康对照者完成了面部情感标签测试和情感韵律识别测试。精神症状采用阳性和阴性症状量表（PANSS）进行评估。结果：与对照组相比，我们观察到两个临床组的面部和声音情感识别的显着损害。这些组的差异仍然显着时，年龄，性别和教育被考虑到considered.Conclusions：研究结果表明，情绪识别障碍可能是独立的精神分裂症的疾病阶段。情感识别缺陷可能在精神病完全表现之前就存在，并可能导致新出现的精神病性障碍中明显的社会认知和社会功能缺陷。
Aim: The study aims to investigate affect recognition in young people at different stages of psychotic illness.Methods: Seventy-nine ultra-high risk patients, 30 first-episode schizophrenia patients and 30 healthy control subjects completed a facial affect labelling test and an affective prosody recognition test. Psychiatric symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS).Results: We observed significant impairments in facial and vocal emotion recognition in both of the clinical groups compared with the control group. These group differences remained significant when age, sex and education were taken into account.Conclusions: The findings suggest that emotion recognition impairments may be independent of the stage of illness in schizophrenia. Deficits in emotion recognition may be present before the full expression of psychotic illness, and may contribute to the social cognition and social functioning deficits apparent in emerging psychotic disorders.
