社会认知在精神分裂症患者中持续受损，可与一般神经认知分离，可预测现实世界的功能，并可接受心理社会治疗。很少有研究实证检验其潜在的因素结构。本研究（1）在精神分裂症谱系障碍和非临床对照的个体样本中检查社会认知的因素结构，（2）探索因素与神经认知、症状和功能的关系。对65名精神分裂症或情感性精神障碍患者和50名对照者的社会认知测量进行了因素分析。由此产生的因素进行了检查，他们的症状和功能的关系。结果表明，在精神分裂症样本的两个因素的结构（社会认知技能和敌对归因风格）和三个因素的结构在非临床样本（敌对归因风格，高层次的推理处理，低层次的线索检测）。在精神分裂症样本中，社会认知技能因素与阴性症状和社会功能显著相关，而敌对归因方式预测阳性和一般精神病理学症状。精神分裂症社会认知的因子结构将敌对归因方式和社会认知技能区分开来，且各因子与精神分裂症相关临床变量的关系存在差异。
Social cognition is consistently impaired in people with schizophrenia, separable from general neurocognition, predictive of real-world functioning, and amenable to psychosocial treatment. Few studies have empirically examined its underlying factor structure. The present study (1) examines the factor structure of social cognition in both a sample of individuals with schizophrenia-spectrum disorders and non-clinical controls, and (2) explores relationships of factors to neurocognition, symptoms and functioning. A factor analysis was conducted on social cognition measures in a sample of sixty-five individuals with schizophrenia or schizoaffective disorder, and fifty control participants. The resulting factors were examined for their relationships to symptoms and functioning. Results suggested a two-factor structure in the schizophrenia sample (social cognition skill and hostile attributional style) and a three-factor structure in the non-clinical sample (hostile attributional style, higher-level inferential processing, and lower-level cue detection). In the schizophrenia sample, the social cognition skill factor was significantly related to negative symptoms and social functioning, while hostile attributional style predicted positive and general psychopathology symptoms. The factor structure of social cognition in schizophrenia separates hostile attributional style and social cognition skill, and each show differential relationships to relevant clinical variables in schizophrenia.
