项目摘要

It is very important to support patients with schizophrenia not only in reducing their symptoms but also improving their interpersonal difficulties. In this study, we proposed the concept of theory of mind to understand the interpersonal difficulties and the symptoms in patients with schizophrenia. It was hypothesized that patients with schizophrenia would fail the tasks of ‘theory of mind' and show the low scores in the scales of LASMI (Life Assessment Scale for Mentally Ill). And it was also predicted that they had positive symptoms such as delusion and hallucination, because they had difficulties to read and infer the minds of others. Fourteen patients with schizophrenia, eight psychiatric controls and seven normal controls participated in the study. PANSS (Positive and Negative Syndrome Scale) was used to evaluate the symptoms of patients with schizophrenia. Hinting task (Janssen et. al., 2003) and comic task (Brunet, et. al., 2003) were used as the measure of 'theory of mind'. Pat … More ients with schizophrenia showed lower scores on the tasks of 'theory of mind' compared to psychiatric controls and normal adults. The result of this study was consistent with former researches (Corcoran, et. al., 1995; Sarfati, et. al., 1997; Brunet, et. al., 2003). The error analysis of hinting task revealed that patients with schizophrenia tended to catch the literal meaning which was described in the task. It was suggested that patients with schizophrenia had difficulty to undersland others' intentions and beliefs depending on the context of the tasks. Therefore it might be able to say that patients with schizophrenia have a similar disorder of ‘theory of mind' which had been found in patients with autism. The patients with schizophrenia who showed the difficulty of abstract thinking in PANSS and failed the hinting task had interpersonal disorder in group activity which was evaluated by LASML. However they did not have positive symptoms. They showed high scares in several sub scales of negative symptoms.The result of the study suggests that the inability to infer others' mind state which was found in patients with schizophrenia will cause their interpersonal difficulties. Further study is needed to make clear the relationship between the disorders of ‘theory mind' and symptoms in patients with schizophrenia. Less

对精神分裂症患者的支持不仅在减轻他们的症状方面，而且在改善他们的人际关系方面也是非常重要的。本研究提出心理理论的概念，以了解精神分裂症患者的人际交往困难和症状。本研究假设精神分裂症患者在心理理论测验中表现不佳，并在精神疾病生活评估量表（LASMI）中表现出较低的得分。他们还被预测会出现妄想和幻觉等阳性症状，因为他们难以阅读和推断他人的想法。14名精神分裂症患者，8名精神病对照和7名正常对照参加了这项研究。采用阳性与阴性症状量表（PANSS）评定精神分裂症患者的症状。提示任务（Janssen et.例如，2003）和漫画任务（Brunet，et.例如，2003）被用作“心理理论”的衡量标准。专利 ...更多信息精神分裂症患者在“心理理论”任务上的得分低于精神病对照组和正常成人。本研究的结果与前人的研究（Corcoran，et.例如，1995; Sarfati，et.例如，1997; Brunet，et.例如，2003年）。提示任务的错误分析表明，精神分裂症患者倾向于抓住任务中描述的字面意义。这表明，精神分裂症患者很难理解他人的意图和信念，这取决于任务的背景。因此，可以说精神分裂症患者有一种类似于自闭症患者的“心理理论”障碍。PANSS中抽象思维困难、提示任务失败的精神分裂症患者，用LASML评定其群体活动中存在人际关系障碍。但他们没有积极的症状。在阴性症状的几个分量表上，精神分裂症患者表现出较高的恐惧感。研究结果表明，精神分裂症患者存在的无法推断他人心理状态的现象，是导致其人际交往困难的原因。精神分裂症患者的"理论思维"障碍与症状的关系有待进一步研究。少
