The risk of violent behavior is known to be higher for patients who suffer from a severe mental disorder. However, specific prediction tools for clinical work in prison psychiatry are lacking. In this single‐center study, two violence risk assessment tools (Forensic Psychiatry and Violence Tool, “FoVOx,” and Mental Illness and Violence Tool, “OxMIV”) were applied to a prison hospital population with a primary psychotic or bipolar disorder and subsequently compared. The required information on all items of both tools was obtained retrospectively for a total of 339 patients by evaluation of available patient files. We obtained the median and inter‐quartile range for both FoVOx and OxMIV, and their rank correlation coefficient along with 95% confidence intervals (CIs)—for the full cohort, as well as for cohort subgroups. The two risk assessment tools were strongly positively correlated (Spearman correlation = 0.83; 95% CI = 0.80–0.86). Such a high correlation was independent of nationality, country of origin, type of detention, schizophrenia‐spectrum disorder, previous violent crime and alcohol use disorder, where correlations were above 0.8. A lower correlation was seen with patients who were 30 years old or more, married, with affective disorder and with self‐harm behavior, and also in patients without aggressive behavior and without drug use disorder. Both risk assessment tools are applicable as an adjunct to clinical decision making in prison psychiatry.

两种暴力风险评估工具在精神病监狱医院人群中的适用性。

已知患有严重精神障碍的患者发生暴力行为的风险更高。但是，缺乏用于监狱精神病学临床工作的特定预测工具。在该单中心研究中，将两种暴力风险评估工具（法医精神病和暴力工具，“ FoVOx”，以及心理疾病和暴力工具，“ OxMIV”）应用于患有原发性精神病或双相情感障碍的监狱医院，随后进行比较。通过评估可用的患者档案，回顾性地获得了总共339位患者的有关这两种工具所有项目的必要信息。我们获得了整个队列以及队列子组的FoVOx和OxMIV的中位数和四分位数范围，以及它们的等级相关系数以及95％置信区间（CI）。两种风险评估工具之间呈高度正相关（Spearman相关系数= 0.83； 95％CI = 0.80–0.86）。如此高的相关性独立于国籍，原籍国，拘留类型，精神分裂症-频谱疾病，先前的暴力犯罪和饮酒障碍，相关性均高于0.8。与年龄在30岁以上，已婚，患有情感障碍和具有自残行为的患者以及没有攻击性行为且没有药物使用障碍的患者相比，相关性较低。两种风险评估工具都可作为监狱精神病学临床决策的辅助工具。精神分裂症谱系障碍，先前的暴力犯罪和饮酒障碍，相关系数均高于0.8。与年龄在30岁以上，已婚，患有情感障碍和具有自残行为的患者以及没有攻击性行为且没有药物使用障碍的患者相比，相关性较低。两种风险评估工具都可作为监狱精神病学临床决策的辅助工具。精神分裂症谱系障碍，先前的暴力犯罪和饮酒障碍，相关系数均高于0.8。与年龄在30岁以上，已婚，患有情感障碍和具有自残行为的患者以及没有攻击性行为且没有药物使用障碍的患者相比，相关性较低。两种风险评估工具都可作为监狱精神病学临床决策的辅助工具。
