Abstract

People with schizophrenia have difficulties recognizing other people's expressions, emotional states, and intentions; however, much less is known about their ability to perceive and understand social interactions. We used scenes depicting social situations to compare responses from 90 volunteers (healthy controls [HC], schizophrenia [SZ], and bipolar disorder [BD] outpatients from the Hospital del Salvador in Valparaíso, Chile) to the question: “What do you think is happening in the scene?” Independent blind raters assigned a score of 0 (absent), 1 (partial), or 2 (present) for each item based on whether the description identifies a) the context, b) the people, and c) the interaction depicted in the scenes. Regarding the context of the scenes, the SZ and BD groups scored significantly lower than the HC group, with no significant difference between the SZ and BD groups. Regarding the identification of the people and the interactions, the SZ group scored lower than the HC and BD groups, with no significant difference between the HC and BD groups. An ANCOVA was used to examine the relationship between diagnosis, cognitive performance, and the results of the social perception test. The diagnosis had an effect on context (p = .001) and people (p = .0001) but not on interactions (p = .08). Cognitive performance had a significant effect on interactions (p = .008) but not on context (p = .88) or people (p = .62). Our main result is that people with schizophrenia may have significant difficulties perceiving and understanding social encounters between other people.

精神分裂症和双相情感障碍患者社会认知的差异
精神分裂症患者难以识别他人的表情、情绪状态和意图;然而,人们对他们感知和理解社会互动的能力知之甚少。我们使用描绘社会情境的场景来比较90名志愿者(智利瓦尔帕莱索萨尔瓦多医院的健康对照[HC]、精神分裂症[SZ]和双相情感障碍[BD]门诊患者)对以下问题的反应:“你认为场景中发生了什么?”,或者基于描述是否识别a)上下文,b)人,以及c)场景中描绘的交互,每个项目2个(存在)。关于场景的背景,SZ和BD组的得分显著低于HC组,SZ组和BD组之间没有显著差异。在人的识别和互动方面,SZ组的得分低于HC组和BD组,HC组和BD组之间没有显著差异。ANCOVA用于检查诊断、认知表现和社会感知测试结果之间的关系。诊断对情境(p=0.001)和人(p=0.0001)有影响,但对互动没有影响(p=0.08)。认知表现对互动有显著影响(p=0.008),但对情境(p=.88)或人(p=.62)没有影响。我们的主要结果是,精神分裂症患者可能在感知和理解他人之间的社交遭遇方面存在显著困难。
