Abstract This study examined the psychometric properties of the MacArthur Community Violence Screening Instrument (MCVSI) in a heterogeneous and integrated sample of adults with mental illness (n = 4,480), including its factor structure, model fit, and psychometric properties as a function of patient sex, race, and primary diagnosis. Factor structure results indicate a unidimensional construct. Item-level analyses revealed that the MCVSI’s difficulty, including the easiest and most difficult items to endorse, sometimes differed across sex, race, and primary diagnosis. However, differential item functioning was minimal across these patient characteristics, with only those without a primary diagnosis of schizophrenia indicating an increased likelihood of having “hit anyone with a fist, object or beaten anyone” compared to those with a primary diagnosis of schizophrenia. Overall, these findings support using the MCVSI as a measure of violence in studies of U.S. adults with mental illness. They also highlight the importance of using more methodologically rigorous approaches to measuring violence, including the ongoing study of the MCVSI across samples and settings.

麦克阿瑟社区暴力筛查仪器的心理测量特性

摘要这项研究研究了MacArthur社区暴力筛查工具（MCVSI）在异类和整合的成年精神病患者（n = 4,480）中的心理测量特性，包括其因子结构，模型拟合和作为患者功能的心理测量特性。性别，种族和主要诊断。因子结构结果表明是一维结构。项目级别的分析表明，MCVSI的难度（包括最容易和最困难的项目），有时在性别，种族和主要诊断方面有所不同。但是，在这些患者特征中，差异项的功能微乎其微，只有那些没有对精神分裂症进行初步诊断的患者，“被拳头击中任何人，反对或殴打任何人”与那些最初诊断为精神分裂症的人相比。总体而言，这些研究结果支持将MCVSI用作对美国成年人患有精神疾病的研究中的暴力手段。他们还强调了使用更严格的方法来测量暴力的重要性，包括正在进行的跨样本和环境的MCVSI研究。
