Much of the research on psychopathy has treated it as a unitary construct operationalized by total scores on one (or more) measures. More recent studies on the Psychopathic Personality Inventory (PPI) suggest the existence of two distinct facets of psychopathy with unique external correlates. Here, the authors report reanalyses of two offender data sets that included scores on the PPI along with various theoretically relevant criterion variables. Consistent with hypotheses, the two PPI factors showed convergent and discriminant relations with criterion measures, many of which would otherwise have been obscured when relying on PPI total scores. These results highlight the importance of examining facets of psychopathy as well as total scores.
许多关于精神病态的研究都将其视为一种单一的结构，通过一项（或多项）测量的总分来进行操作化定义。最近对《精神病态人格问卷》（PPI）的研究表明，精神病态存在两个不同的方面，且具有独特的外部关联。在此，作者报告了对两个罪犯数据集的重新分析，这些数据集包括PPI得分以及各种理论上相关的标准变量。与假设一致，PPI的两个因素与标准测量显示出收敛和区分关系，而如果依赖PPI总分，其中许多关系可能会被掩盖。这些结果凸显了检查精神病态的各个方面以及总分的重要性。
