Individuals with schizophrenia (SCZ) form less accurate mental representations of the self and others, which contributes to social dysfunction. It remains unclear, however, whether such deficits extend to metaperception (MP), the ability to understand how others view one’s own personality. In Phase 1 of this study, 30 individuals with SCZ and 30 healthy controls (HCs) had a videotaped conversation with an experimenter and then completed a Big Five trait questionnaire, with the goal of predicting how strangers who view their videos would rate them on the five personality traits. In Phase 2, separate participants watched the videos and rated targets’ personalities. These ratings served as “The Truth” to which Phase 1 MPs were compared for Tracking Accuracy (i.e., extent to which The Truth predicts MPs) and Directional Bias (i.e., extent to which MPs overestimate or underestimate the truth). Tracking Accuracy was weaker in SCZ than in HC for Openness, Conscientiousness, and Agreeableness. Moreover, Tracking Accuracy and Directional Bias of MPs in SCZ were unrelated to mentalizing abilities and clinical insight. Our results suggest that the capacity to understand how others view one’s own personality is impaired in SCZ and may be a distinct component of the social cognitive system.

精神分裂症人格的元认知

精神分裂症患者（SCZ）形成的自我和他人心理表征较不准确，这会导致社会功能障碍。然而，尚不清楚这种缺陷是否扩展到元认知（MP），即理解他人如何看待自己的人格的能力。在这项研究的第1阶段，有30位SCZ个体和30位健康对照（HCs）与实验者进行了录像对话，然后完成了“大五人”特质问卷，目的是预测观看视频的陌生人对他们的评价。五个人格特质。在第2阶段，单独的参与者观看了视频并评估了目标人物的个性。这些评分用作“真相”，将第一阶段MP的跟踪准确度（即The Truth预测MP的程度）和定向偏差（即，国会议员高估或低估了真相的程度）。SCZ的跟踪准确性比HC的公开性，尽责性和令人愉快程度要弱。此外，SCZ中MP的跟踪准确性和定向偏差与思维能力和临床见解无关。我们的研究结果表明，了解他人如何看待自己的个性的能力在SCZ中受到损害，并且可能是社会认知系统的一个独特组成部分。
