Background and Hypothesis Reduced social cognition has been reported in individuals who have committed interpersonal violence. It is unclear if individuals with schizophrenia and a history of violence have larger impairments than violent individuals without psychosis and non-violent individuals with schizophrenia. We examined social cognition in two groups with violent offenses, comparing their performance to non-violent individuals with schizophrenia and healthy controls. Study Design Two social cognitive domains were assessed in four groups: men with a schizophrenia spectrum disorder with (SSD-V, n = 27) or without (SSD-NV, n = 42) a history of violence, incarcerated men serving preventive detention sentences (V, n = 22), and healthy male controls (HC, n = 76). Theory of mind (ToM) was measured with the Movie for the Assessment of Social Cognition (MASC), body emotion perception with Emotion in Biological Motion (EmoBio) test. Study Results Kruskal–Wallis H-tests revealed overall group differences for social cognition. SSD-V had a global and clinically significant social cognitive impairment. V had a specific impairment, for ToM. Binary logistic regressions predicting violence category membership from social cognition and psychosis (SSD status) were conducted. The model with best fit, explaining 18%–25% of the variance, had ToM as the only predictor. Conclusions Social cognitive impairment was present in individuals with a history of violence, with larger and more widespread impairment seen in schizophrenia. ToM predicted violence category membership, psychosis did not. The results suggest a role for social cognition in understanding interpersonal violence.

有或没有精神分裂症的男性的暴力犯罪：社会认知的作用？

背景和假设 据报道，实施人际暴力的个人社会认知能力下降。目前尚不清楚有暴力史的精神分裂症患者是否比没有精神病的暴力患者和患有精神分裂症的非暴力患者有更大的损伤。我们检查了两组有暴力犯罪行为的社会认知，将他们的表现与患有精神分裂症和健康对照组的非暴力个体进行比较。研究设计 两个社会认知领域被分为四组进行评估：患有精神分裂症谱系障碍的男性（SSD-V，n = 27）或没有（SSD-NV，n = 42）暴力史，服预防性拘留的被监禁男性（V，n = 22）和健康男性对照（HC，n = 76）。心理理论（ToM）通过社会认知评估电影（MASC）进行测量，身体情绪感知通过生物运动情感（EmoBio）测试进行测量。研究结果 Kruskal-Wallis H 检验揭示了社会认知的整体群体差异。SSD-V 具有全球性和临床上显着的社交认知障碍。V 对 ToM 有特定的损害。进行了二元逻辑回归，根据社会认知和精神病（SSD 状态）预测暴力类别成员资格。最佳拟合模型解释了 18%–25% 的方差，并以 ToM 作为唯一的预测变量。结论 有暴力史的个体存在社会认知障碍，精神分裂症患者的社会认知障碍更大、更广泛。ToM 预测了暴力类别的成员资格，而精神病则没有。结果表明社会认知在理解人际暴力方面发挥着作用。
