摘要
目的：对扩展版布罗塞特暴力风险评估量表（BVC—E）进行效度和信度检验。方法：应用BVC-E对679例符合疾病和有关健康问题的国际统计分类第十次修订本（ICD-10）诊断的精神障碍患者进行评估，计算内容效度指数评价其内容效度；采用量表的灵敏度、特异度、ROC曲线下面积评价其效标效度；采用组内相关系数评价评定者间信度；计算Cronbach α系数评价内部一致性信度。结果：BVC—E量表水平的内容效度指数为0．94；以语言攻击、物品攻击、他人攻击、自身攻击作为结果变量时，ROC曲线下面积为0．941，当截断点为3时，其灵敏度高于原量表BVC（89．4％vs．78．9％，P〈0．001）；以他人攻击作为结果变量时，ROC曲线下面积为0．974，当截断点为4时，其灵敏度高于原量表BVC（92．7％vs．74．5％，P〈0．001）；量表各条目间的组内相关系数为0．930～0．984，总的组内相关系数为0．985；Cronbach α系数为0．732。结论：BVC—E量表在扩展后灵敏度有所提升，更能精确地预测精神科的暴力事件。
Objective： To test the validity and reliability of the BrOset Violence Checklist-Extended （BVC-E）. Methods： 679 patients who met the diagnosis criteria for mental disorders according to the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision （ICD-10） were selected to be assessed with BVC-E. The content validity was evaluated by the content validity index （CVI）. The criterion validity was evaluated by sensitivity, specificity and the area under the ROC curve. The intraclass correlation coefficient （ICC） was used to test the inter-rater reliability. The internal consistency reliability of the scale was tested by Cronbach α coefficient. Results： The scale-level CVI of the BVC-E was 0. 94, When the outcome variable was the occurrence of any verbal or nonverbal behavior that was threatening to self or others, the area under the ROC curve was 0. 941. When the cut-off was 3, the sensitivity of BVC-E was higher than that of the original scale BVC（89. 4% vs. 78.9%, P 〈 0. 001）. When the outcome variable was the occurrence of any physical behavior that was threatening to others, the area under the ROC curve was 0. 974. When the cut-off was 4, the sensitivity of BVC-E was higher than that of the original scale BVC （92. 7% vs. 74. 5%, P 〈0. 001）. The ICC of every item was 0. 930 -0. 984 and the overall ICC was 0. 985. The Cronbach a coefficient was 0. 732. Conclusion： The sensitivity of the scale is improved after extended and BVC-E could predict psychiatric violence more accurately.
