Rather than focusing on the extensively studied social perception and recognition impairments in people with schizophrenia, this study focuses on the type of social information considered relevant by people with schizophrenia, and how they use it to arrive at conclusions about social situations.
Participants included 50 outpatients with schizophrenia from the Hospital del Salvador at Valparaíso, Chile, and 50 healthy comparators matched by age and gender. Subjects completed the Social Information Preference Test (SIPT), which presents scenes depicting ambiguous social situations with faces, thoughts, and facts about the scene hidden from view. Participants were required to select a limited number of these items and then choose between possible interpretations of the scene (positive, neutral, or negative). Additionally, they are asked to provide a feeling of certainty in their answers, using a 7-point visual analogue scale.
People with schizophrenia, as well as controls had a strong preference for knowing the thoughts of the characters. Both groups were least likely to choose emotional expressions. Patients were significantly less likely to choose object/information than controls. Both groups showed a high certainty in their responses and no tendency to choose negative interpretations.
compensated clinical status of the patients may have influenced the results.
The results of this study suggest that, despite difficulties perceiving clues about the mental state of others, people with schizophrenia use this information to make sense of social situations, and apparently, they do not have problems in understanding social interactions.
本研究并非聚焦于已被广泛研究的精神分裂症患者的社会认知和识别障碍，而是关注精神分裂症患者认为相关的社会信息类型，以及他们如何利用这些信息得出关于社会情境的结论。
参与者包括来自智利瓦尔帕莱索萨尔瓦多医院的50名门诊精神分裂症患者，以及50名年龄和性别匹配的健康对照者。受试者完成了社会信息偏好测试（SIPT），该测试呈现描绘模糊社会情境的场景，人物的面部、想法和场景相关事实均被遮挡。参与者被要求从这些项目中选择有限数量的内容，然后在对场景的可能解释（积极、中性或消极）之间进行选择。此外，要求他们使用7点视觉模拟量表对自己答案的确定程度进行打分。
精神分裂症患者和对照组都强烈倾向于了解人物的想法。两组最不可能选择的都是情感表达。患者选择物体/信息的可能性明显低于对照组。两组对自己的回答都表现出高度的确定性，且没有选择消极解释的倾向。
患者的代偿性临床状态可能影响了结果。
本研究结果表明，尽管精神分裂症患者在感知他人心理状态线索方面存在困难，但他们仍利用这些信息来理解社会情境，显然，他们在理解社会互动方面没有问题。
