Racial status has an important role in schizophrenia, with African American samples being rated lower than White participants on a range of constructs. In many studies, however, demographic factors are not accounted for. In the present study, African American (n = 106) and White participants (n = 81) were compared on symptom severity and emotion recognition scales while controlling for other demographic factors. Contrary to our hypothesis, there were no differences in symptoms between racial groups. However, White participants performed better on an emotion recognition measure than African Americans. These differences were most prominent in response to negatively-valenced stimuli. This study replicated previous findings of racial differences in emotion recognition but not symptom severity. Future research should assess the role of racial identity on symptom severity. In addition, further research is needed to assess if utilising multi-ethnic stimuli improves performance by racial minorities on emotion recognition measures.

比较非裔美国人和白人样本与精神分裂症的症状和情绪识别


种族地位在精神分裂症中起着重要作用，非裔美国人样本在一系列构建中的评分低于白人参与者。然而，许多研究并未考虑人口因素。在本研究中，对非裔美国人 ( n = 106) 和白人参与者 ( n = 81) 的症状严重程度和情绪识别量表进行了比较，同时控制了其他人口统计因素。与我们的假设相反，种族群体之间的症状没有差异。然而，白人参与者在情绪识别测试中的表现比非裔美国人更好。这些差异在对负价刺激的反应中最为突出。这项研究重复了之前关于情绪识别方面种族差异的发现，但没有重复症状严重程度的种族差异。未来的研究应该评估种族认同对症状严重程度的作用。此外，还需要进一步的研究来评估利用多种族刺激是否可以提高少数族裔在情绪识别方面的表现。
