Research indicates that many with schizophrenia experience deficits in metacognitive capacity or the ability to form complex representations of themselves and others. Previous work has found that metacognitive capacity in schizophrenia is correlated with symptoms, insight, and neurocognitive deficits. We sought to replicate these results in a sample of Italian participants treated in a community setting. Metacognition was assessed with the abbreviated Metacognition Assessment Scale and correlated with concurrent assessment of symptoms, insight, and neurocognitive abilities, including verbal and visual memory, premorbid intelligence, processing speed, and executive function. Correlations revealed that, consistent with previous work, lesser capacity for self-reflectivity was related to greater levels of negative symptoms, poorer insight, neurocognitive impairment (particularly impairments in verbal and visual memory) premorbid intelligence, and processing speed. Other metacognitive domains were also linked to poorer neurocognition. Results support contentions that deficits in metacognition are linked with negative symptoms, insight, and neurocognitive deficits.
研究表明，许多精神分裂症患者在元认知能力或形成关于自己和他人的复杂表征的能力方面存在缺陷。先前的研究发现，精神分裂症患者的元认知能力与症状、自知力及神经认知缺陷相关。我们试图在一组接受社区治疗的意大利参与者样本中重现这些结果。采用简化的元认知评估量表对元认知进行评估，并将其与症状、自知力及神经认知能力的同步评估相关联，这些神经认知能力包括言语和视觉记忆、病前智力、处理速度和执行功能。相关性分析显示，与先前的研究一致，自我反思能力较弱与更严重的阴性症状、更差的自知力、神经认知损害（尤其是言语和视觉记忆损害）、病前智力及处理速度相关。其他元认知领域也与较差的神经认知相关。结果支持了元认知缺陷与阴性症状、自知力及神经认知缺陷相关的观点。
