Assessing risk for violence is a complex task often based on not objective or structured clinical evaluations. HCR-20 Assessing Risk for Violence has been used in several countries to increase the accuracy of this exam. The purpose of this study was to inform on central aspects of this instrument, as well as the results of the reliability assessment of the HCR-20 Assessing Risk for Violence in a Brazilian inpatient criminal population.
Two examiners independently assessed a random sample of 30 patients that were under criminal commitment at the Mauricio Cardoso Forensic Psychiatric Institute
Mean consensus values means were as follows: Historical = 13.1; Clinical = 4.8 and Risk management = 5.8. The value of the Intraclass Correlation Coefficient for the score of subscale Historical was 0.97, for subscale Clinical it was 0.94, and for subscale Risk management, 0.96. As to the individual items of the HCR-20 Assessing Risk for Violence, the result of the Intraclass Correlation Coefficient was good to excellent (mean = 0.97; interval, from 0.60 to 0.99).
The interrater reliability of the Brazilian version of the HCR-20 Assessing Risk for Violence scale was similar to the results of studies in other countries.
评估暴力风险是一项复杂的任务，通常基于非客观或结构化的临床评估。HCR-20 评估暴力风险已在多个国家使用，以提高该评估的准确性。本研究旨在介绍该工具的核心方面，以及 HCR-20 评估暴力风险在巴西住院刑事人群中的可靠性评估结果。
两名评估员对 Mauricio Cardoso 法医精神病学研究所刑事约束下的 30 名随机患者进行了独立评估。
平均共识值平均值如下：历史= 13.1；临床= 4.8 和风险管理= 5.8。历史分量表评分的组内相关系数为 0.97，临床分量表为 0.94，风险管理分量表为 0.96。至于 HCR-20 评估暴力风险的个别项目，组内相关系数的结果为良好至优秀（平均值= 0.97；区间为 0.60 至 0.99）。
HCR-20 评估暴力风险量表的巴西版本的评分者间可靠性与其他国家的研究结果相似。
