引言虽然伴随精神病的现象学令人着迷，但迄今为止的实证检验都是定性的，因此在关于导致妄想形成和维持的实际潜在认知机制的临床结论上受到限制，这常常让患者感到痛苦。方法我们调查了一名精神病患者的一些与自我和他人有关的妄想的内部认知结构（即联系），该患者的语言非常流利，因此能够清晰地描述他的情况。现象学经验。为此，我们采用了聚类方法（HICLAS 析取模型）与标准神经心理学测试相结合。结果拟合良好但简约的解决方案揭示了与某些人相关的独特特征集的缺失，这些发现提供了令人信服的案例，说明了在某些情况下真实的人和妄想的人之间的混淆。结论我们在一名患者中说明了该方法，并表明它足够敏感，可以探索妄想的结构，这与标准的神经心理学和临床评估相结合有望实现有助于揭示精神病妄想的潜在机制。
INTRODUCTIONAlthough the phenomenology accompanying psychoses is fascinating, hitherto empirical examinations have been qualitative and thus limited in their clinical conclusions regarding the actual underlying cognitive mechanisms responsible for the formation and maintenance of the delusion, which is often distressing to the patient.METHODSWe investigated the internal cognitive structure (i.e., connections) of some delusions pertaining to self and others in a patient with psychosis who was very fluent and thus able to provide a lucid account of his phenomenological experiences. To this end we employed a clustering method (HICLAS disjunctive model) in conjunction with standard neuropsychological tests.RESULTSA well-fitting, but parsimonious solution revealed the absence of unique feature sets associated with certain persons, findings that provide a compelling case underlying the confusion in certain instances between real and delusional people.CONCLUSIONSWe illustrate the methodology in one patient and suggest that it is sensitive enough to explore the structure of delusions, which in conjunction with standard neuropsychological and clinical assessments promises to be useful in uncovering the mechanisms underlying delusions in psychosis.
