Deficits in facial affect recognition have been shown repeatedly in schizophrenia. However, the stability of this deficit over time remains to be clarified. A total of 36 remitted, 32 acutely ill schizophrenic patients and 21 healthy volunteers participated in a cross-sectional and longitudinal study. All subjects were assessed twice within 4 weeks (acute schizophrenics and normal controls), or 12 weeks, respectively (remitted schizophrenics). Subjects had to identify six basic emotions from corresponding facial expressions shown as photographs on a video screen. Both acute and remitted schizophrenics demonstrated a stable deficit over time in facial affect recognition unrelated to psychopathology and medication. This suggests that deficits in facial affect recognition in schizophrenia reflect a trait-like, rather than a state-dependent, characteristic.
面部表情识别缺陷在精神分裂症中已被反复证实。然而，这种缺陷随时间的稳定性仍有待阐明。共有36名康复期、32名急性期精神分裂症患者以及21名健康志愿者参与了一项横断面和纵向研究。所有受试者分别在4周内（急性期精神分裂症患者和正常对照组）或12周内（康复期精神分裂症患者）接受两次评估。受试者必须从视频屏幕上显示的相应面部表情照片中识别六种基本情绪。急性期和康复期精神分裂症患者在面部表情识别方面均表现出随时间推移的稳定缺陷，且与精神病理学和药物治疗无关。这表明精神分裂症患者面部表情识别缺陷反映的是一种特质性特征，而非状态依赖性特征。
