Abstract

Introduction: Low-pleasure beliefs are found in both patients with schizophrenia (SZ) and individuals with high social anhedonia (SocAnh), and are associated with anhedonia. However, little is known about the development and maintenance of these low-pleasure beliefs in the clinical and subclinical populations. We investigated whether patients with SZ and individuals with high SocAnh have deficits in updating their beliefs, which may contribute to the understanding of the formation and maintenance of low-pleasure beliefs.

Methods: The Modified Belief Updating Task was administered to assess belief-updating patterns in a clinical sample (36 SZ patients and 30 matched controls) and a subclinical sample (27 individuals with high SocAnh and 30 matched controls).

Results: We found that compared with controls, SZ patients updated their beliefs to a greater extent and more frequently when receiving bad news for positive life events, but not for negative life events. Moreover, individuals with high SocAnh also exhibited similar patterns in updating their beliefs for positive life events after controlling depressive symptoms.

Conclusions: Our findings suggest that negative belief-updating patterns for positive events may play an important role in the formation and maintenance of low-pleasure beliefs in patients with SZ and individuals with high SocAnh.

精神分裂症和社交快感缺乏症患者积极日常生活事件的负性信念更新偏倚。

低愉悦信念存在于精神分裂症患者(SZ)和高社交快感缺乏症患者(SocAnh)中，并与快感缺乏症相关。然而，在临床和亚临床人群中，人们对这些低快乐信念的发展和维持知之甚少。我们调查了SZ患者和高SocAnh个体是否在更新他们的信念方面存在缺陷，这可能有助于理解低快乐信念的形成和维持。方法:采用改良信念更新任务评估临床样本(36例SZ患者和30例匹配对照)和亚临床样本(27例高SocAnh个体和30例匹配对照)的信念更新模式。结果:我们发现，与对照组相比，SZ患者在收到积极生活事件的坏消息时更新信念的程度更大，频率更高，而在收到消极生活事件的坏消息时更新信念的频率更高。此外，高SocAnh的个体在控制抑郁症状后也表现出类似的模式，即更新他们对积极生活事件的信念。结论:我们的研究结果表明，积极事件的消极信念更新模式可能在SZ患者和高SocAnh个体的低快乐信念的形成和维持中起重要作用。

期刊介绍： Cognitive Neuropsychiatry (CNP) publishes high quality empirical and theoretical papers in the multi-disciplinary field of cognitive neuropsychiatry. Specifically the journal promotes the study of cognitive processes underlying psychological and behavioural abnormalities, including psychotic symptoms, with and without organic brain disease. Since 1996, CNP has published original papers, short reports, case studies and theoretical and empirical reviews in fields of clinical and cognitive neuropsychiatry, which have a bearing on the understanding of normal cognitive processes. Relevant research from cognitive neuroscience, cognitive neuropsychology and clinical populations will also be considered.
