背景：关于精神病超高风险人群中暴力危险因素的流行程度的数据很少。目的：本研究的目的是估计那些参加精神病发展超高风险人群的常规临床服务的暴力危险因素的横断面流行率。方法：回顾所有34例患者4周内的病例记录，并对所有临床医生进行访谈。收集的信息包括性别、当前的暴力意念、暴力史（包括定罪）、他人表达的关切、酗酒或滥用药物问题、嫉妒、多疑、易怒、愤怒和相关的阈下精神症状。还收集了有关保护因素的信息，包括参与治疗。结果：38% （n = 13）有暴力行为史，79.4% （n = 27）被认为目前正经历着严重的怀疑，47.1% （n = 16）被认为有愤怒问题。29% （n = 10）以前有过已知的暴力犯罪前科。三分之二（n = 8）被确定有暴力风险的人被描述为正在接受治疗。结论：在这个小样本中，暴力危险因素的发生率很高。迫切需要进一步研究更大的样本和更好的方法来调查这一群体的暴力风险，并确定亚临床精神病症状的贡献，如果有的话。
Background: There is little data available on the prevalence of violence risk factors in people at ultra-high risk of developing psychosis.Aim: The aim of this study was to provide an estimate of the cross-sectional prevalence of violence risk factors in those attending a routine clinical service for people at ultrahigh risk of developing psychosis.Methods: The case notes of all 34 clients receiving treatment over a 4-week period were reviewed and all clinicians were interviewed. Information was gathered regarding gender, current violent ideation, history of violence (including convictions), expressions of concern from others, problems with alcohol or substance misuse, jealousy, suspiciousness, irritability, anger and relevant subthresh-old psychotic symptoms. Information on protective factors, including treatment engagement, was also gathered.Results: Thirty-eight per cent (n = 13) had a history of violent behaviour, 79.4% (n = 27) were thought to be currently experiencing significant levels of suspiciousness and 47.1% (n = 16) were thought to have problems with anger. Twenty-nine per cent (n = 10) had previous known convictions for violence. Two-thirds (n = 8) of those where risk of violence was identified were described as being engaged with treatment.Conclusion: There was a high prevalence of violence risk factors in this small sample. Further research with larger samples and better methodology is urgently required to investigate risk of violence in this group and determine the contribution, if any, of subclinical psychotic symptoms.
