Information on patterns and correlates of the violent behaviour of individuals with schizophrenia is largely limited to populations in developed countries. Data from a World Health Organization epidemiological study of schizophrenia and related disorders, the Determinants of Outcome of Severe Mental Disorders (DOSMD), presented an opportunity to study patterns of violence across multinational settings.
Centres in 10 countries participated in the DOSMD study. An incidence sample of 1017 patients with schizophrenia who had their first-in-lifetime contact with a helping agency as a result of their psychotic symptoms was obtained. Data were available on their history of violent behaviour, substance use, and demographics.
The occurrence rate of assault in the entire cohort was 20.6 per hundred, but the rate was three times higher in the developing countries (31.5 per hundred) than in developed countries (10.5 per hundred). History of assault was associated with positive symptoms, such as excitement and auditory hallucinations, and with serious alcohol problems.
The cultural context and the specific characteristics of the disease in individuals with schizophrenia may interactively affect rates of violent behaviour.
关于精神分裂症患者暴力行为模式及其相关因素的信息大多局限于发达国家的人群。世界卫生组织一项关于精神分裂症及相关障碍的流行病学研究——严重精神障碍结局的决定因素（DOSMD）的数据，提供了一个研究跨国环境下暴力行为模式的机会。
10个国家的研究中心参与了DOSMD研究。获得了1017例因精神症状而首次与救助机构接触的精神分裂症患者的发病样本。有关于他们暴力行为史、物质使用情况和人口统计学的数据。
整个队列中攻击行为的发生率为每百人20.6例，但发展中国家的发生率（每百人31.5例）是发达国家（每百人10.5例）的三倍。攻击行为史与兴奋和幻听等阳性症状以及严重的酒精问题有关。
文化背景和精神分裂症患者疾病的特定特征可能相互作用影响暴力行为发生率。
