精神分裂症的自我评估障碍已被证明具有功能和临床意义。此前的研究表明，过度自信可能与精神分裂症患者较差的认知表现有关，而对表现的意识下降可能与残疾有关。然而，过度自信在健康的人中也很常见。本研究探讨了在社会认知测试，在性能的信心，分配给任务的努力，精神分裂症患者和健康对照组（HC）的信心和相关性能之间的相关性。措施包括抑郁症，社会认知能力和社会功能的自我报告。基于表现的情绪识别测试评估了社会认知表现，并为信心判断提供了基础。虽然精神分裂症患者的总体自信水平降低，但有相当一部分精神分裂症患者表现出极端的过度自信，这些人的表现最差，抑郁症最少。此外，许多人道主义协调员也高估了自己的业绩。与HC相比，精神分裂症患者没有调整他们的努力以匹配任务难度。信心与患者的任务表现关系最小，但在正确和不正确的反应中，与HC中更快速的决策相关。在这两个样本中，社会认知指标的表现与社会功能的自我报告关系最小。这些数据表明，总体自我评估基于多种因素，在没有关于业绩的反馈的情况下，信心会影响自我评估。
Impairments in self-assessment in schizophrenia have been shown to have functional and clinical implications. Prior studies have suggested that overconfidence can be associated with poorer cognitive performance in people with schizophrenia, and that reduced awareness of performance may be associated with disability. However, overconfidence is common in healthy individuals as well. This study examines the correlations between performance on a social cognitive test, confidence in performance, effort allocated to the task, and correlates of confidence in patients with schizophrenia and healthy controls (HC). Measures included self-reports of depression, social cognitive ability, and social functioning. A performance-based emotion recognition test assessed social cognitive performance and provided the basis for confidence judgments. Although schizophrenia patients had reduced levels of overall confidence, there was a substantial subset of schizophrenic patients who manifested extreme overconfidence and these people had the poorest performance and reported the least depression. Further, a substantial number of HC over-estimated their performance as well. Patients with schizophrenia, in contrast to HC, did not adjust their effort to match task difficulty. Confidence was minimally related to task performance in patients but was associated with more rapid decisions in HC, across both correct and incorrect responses. Performance on social cognitive measures was minimally related to self-reports of social functioning in both samples. These data suggest global self-assessments are based on multiple factors, with confidence affecting self-assessments in the absence of feedback about performance.
