Research suggests that many with schizophrenia experience deficits in the ability to make discrete judgments about the thoughts and feelings of others as well as to form larger integrated representations of themselves and others. Little is known about whether these difficulties may be distinguished from one another and whether they are linked with different outcomes.
We administered three assessments of social cognition which tapped the ability to identify emotions and intentions and two metacognitive tasks which called for the formation of more integrated and flexible representations of the self and others. We additionally assessed symptoms, social functioning and neurocognition. Participants were 95 individuals with a schizophrenia spectrum disorder.
A principle components analysis followed by a varimax rotation revealed two factors which accounted for 62% of the variance. The first factor was comprised of the three social cognition tests and the second of two tasks that tapped the ability to create representations of oneself and others which integrate more discreet information. The first factor was uniquely correlated with negative symptoms, and the second was uniquely correlated with social function.
Results suggest that deficits in social cognition and metacognition represent different forms of dysfunction in schizophrenia.
研究表明，许多精神分裂症患者在识别他人的思想和感受的能力以及形成对自己和他人的更大、更综合的整体表象方面存在缺陷。目前还不清楚这些困难是否可以相互区分，以及它们是否与不同的结果有关。
我们使用了三种评估社会认知的方法，这些方法可以测试识别情绪和意图的能力，以及两种元认知任务，这两种任务需要对自我和他人进行更综合和灵活的表象。我们还评估了症状、社会功能和神经认知。参与者是 95 名精神分裂症谱系障碍患者。
主成分分析后进行方差极大旋转，结果显示有两个因素可以解释 62%的方差。第一个因素由三个社会认知测试组成，第二个因素由两个任务组成，这些任务可以测试将更离散的信息整合到自我和他人的表象中的能力。第一个因素与阴性症状独特相关，第二个因素与社会功能独特相关。
结果表明，社会认知和元认知缺陷代表了精神分裂症不同形式的功能障碍。
