A wealth of research has underscored the strong relationship between PCL-R scores and recidivism. However, mounting criticism cites the PCL-R's cumbersome administration procedures and failure to adequately measure core features associated with the construct of psychopathy (Skeem, Polaschek, Patrick, & Lilienfeld, 2011). In light of these concerns, this study examined the PPI and the PPI-R, which were designed to measure core personality features associated with psychopathy (Lilienfeld & Andrews, 1996; Lilienfeld & Widows, 2005). Study one examined the PPI relative to the PCL-R and examined its factor structure. The instruments shared few significant correlations and neither the PCL-R nor the PPI significantly predicted recidivism. Study two examined the PPI-R relative to the PCL-R, the PPI, both history of violence and future criminal activity and measure of related constructs. The PPI-R was significantly correlated with measures of empathy and criminal thinking and the factors were related to a history of violence and predicted future violent criminal behavior.
大量研究强调了 PCL-R 评分与累犯之间的密切关系。然而，越来越多的批评指出 PCL-R 的繁琐管理程序，以及未能充分衡量与精神病态结构相关的核心特征（Skeem、Polaschek、Patrick 和 Lilienfeld，2011 年）。有鉴于此，本研究考察了 PPI 和 PPI-R，这两种测试旨在衡量与精神病态相关的核心人格特征（Lilienfeld 和 Andrews，1996 年；Lilienfeld 和 Widows，2005 年）。研究一考察了 PPI 与 PCL-R 的关系，并考察了其因子结构。这两种工具之间的相关性很小，PCL-R 和 PPI 都不能显著预测累犯。研究二考察了 PPI-R 与 PCL-R、PPI、暴力史和未来犯罪活动以及相关结构的测量之间的关系。PPI-R 与同理心和犯罪思维的测量显著相关，并且这些因素与暴力史有关，并预测了未来的暴力犯罪行为。
