背景精神病的诊断对暴力风险评估具有重要意义。目的调查英国和北美的精神病症状结构（修订后的精神病检查表（PCL-R））是否相同，以及该测量方法在这两个地区的得分是否相同。方法采用验证性因子分析和项目反应理论方法对大样本的PCL-R评分进行分析。结果不同文化背景的精神病综合征结构是不变的，三个不同的因素构成了精神病的上级综合征。然而，不同文化的PCL-R分数并不相等：在英国，同样的精神病水平与较低的PCL-R分数相关。反映情感症状的项目具有最高的跨文化稳定性。结论：在英国获得的PCL-R评分与在北美获得的评分没有直接可比性。在英国，当PCL-R被用于做出重要的临床决定时，必须谨慎行事。利益声明无。
Background The diagnosis of psychopathy is important for violence risk assessment.Aims To investigate whether the syndromal structure of psychopathy, as measured by the Psychopathy Checklist - Revised (PCL-R), is the same in the UK and North America, and whether this measure yields scores that are equivalent in these two regions.Method Confirmatory factor analytic and item response theory methods were applied to large samples of PCL-R ratingsResults The syndromal structure of psychopathy was invariant across cultures, three distinct factors underpinning the superordinate syndrome of psychopathy. However, PCL-R scores were not equivalent across cultures: the same level of psychopathy was associated with lower PCL-R scores in the UK. Items that reflected affective symptoms had the highest cross-cultural stability.Conclusions Scores on the PCL-R obtained in the UK are not directly comparable with those obtained in North America. Care must be exercised when the PCL-R is used to make important clinical decisions in the UK.Declaration of interest None.
