The cognitive model of negative symptoms suggests that some dysfunctional beliefs mediate the relationship between neurocognitive deficits and negative symptoms and disability. This study tested the hypothesis that dysfunctional performance beliefs mediate neurocognitive deficits, negative symptoms, and disability. We used a hierarchal component model with 85 men patients diagnosed with chronic schizophrenia. Results showed a moderate to strong correlation between dysfunctional performance beliefs, neurocognitive deficits, negative symptoms, and disability. These results support the Hierarchal component model (HCM) of the cognitive model of negative symptoms. Our results indicated that the disability in schizophrenia is mediated through dysfunctional performance beliefs, neurocognitive deficits, and negative symptoms pathway. Further, dysfunctional performance beliefs have a crucial role in this pathway. Therefore, targeting this vicious cycle of dysfunctional beliefs can improve disability in patients with schizophrenia.
阴性症状的认知模型表明，一些功能失调的信念介导了神经认知缺陷与阴性症状及残疾之间的关系。本研究检验了功能失调的表现信念介导神经认知缺陷、阴性症状和残疾这一假设。我们对85名被诊断为慢性精神分裂症的男性患者使用了层次成分模型。结果显示，功能失调的表现信念、神经认知缺陷、阴性症状和残疾之间存在中度到高度的相关性。这些结果支持了阴性症状认知模型的层次成分模型（HCM）。我们的结果表明，精神分裂症中的残疾是通过功能失调的表现信念、神经认知缺陷和阴性症状途径介导的。此外，功能失调的表现信念在这一途径中起着关键作用。因此，针对这种功能失调信念的恶性循环可以改善精神分裂症患者的残疾状况。
