Facial affect discrimination and identification were assessed in 86 clinical high-risk individuals and compared with 50 individuals with first-episode psychosis, 53 with multi-episode schizophrenia and 55 non-psychiatric controls. On the identification task the non-psychiatric controls performed significantly better than all other groups, and on discrimination significantly better than both patient groups. Deficits in facial affect recognition appear to be present before the onset of psychosis and may be a vulnerability marker.
对86名临床高危个体进行了面部表情辨别和识别评估,并与50名首发精神病患者、53名多发作精神分裂症患者和55名非精神科对照者进行了比较。在识别任务中,非精神科对照者的表现明显优于所有其他组,在辨别任务中明显优于两个患者组。面部表情识别缺陷似乎在精神病发作前就已存在,可能是一种易感性标志物。
