The present research tested the four-factor Psychopathy Checklist: Screening Version (PCL:SV) latent variable model for structural invariance across ethnicity in a large sample of civil psychiatric patients. In addition, it also examined how Barratt (1994) impulsivity and Novaco (1994) anger latent variables were related to the psychopathy dimensions within and across ethnicity. The data were analyzed with Mplus (Muthen & Muthen, 2001), and results indicated that the four-factor model was invariant across Caucasian and African American males in terms of both item factor loadings and thresholds. However, differential relations between the external correlates and the psychopathy dimensions were found across groups, suggesting that the association between impulsivity and psychopathy may be moderated by ethnicity.
本研究在一大群民事精神病患者样本中，检验了四因素版精神病态量表：筛查版（PCL:SV）潜在变量模型在不同种族间的结构不变性。此外，研究还考察了巴拉特（1994年）冲动性和诺瓦科（1994年）愤怒潜在变量与不同种族内及不同种族间精神病态维度的关系。数据采用Mplus软件（慕曾与慕曾，2001年）进行分析，结果表明，就项目因素负荷和阈值而言，四因素模型在白种人和非裔美国男性中具有不变性。然而，不同组之间发现外部相关因素与精神病态维度之间存在差异关系，这表明冲动性与精神病态之间的关联可能受到种族的调节。
