ABSTRACT

The objective of the current study was to develop a revised version of the Psychopathic Personality Traits Scale (PPTS-R) with an increased number of indicators to more reliably capture the four dimensions of the Psychopathic Personality Traits Model (PPTM). Dimensionality, construct validity, and reliability of the PPTS-R was examined among general (N = 1989) and prison (N = 638) population. Three competing models of the PPTS-R were specified and tested using Mplus with MLR estimation. The current research provides evidence that the 28-item PPTS-R using 5-point Likert scale is best captured by four factors, including affective responsiveness, cognitive responsiveness, interpersonal manipulation, and egocentricity and can be effectively used in forensic and general population. Additionally, the PPTS-R will allow, for the first time, for meaningful comparisons between forensic and non-forensic populations with regards to the prevalence of psychopathic traits.

摘要

本研究的目的是开发修订版的精神病人格特质量表（PPTS-R），增加指标数量，以更可靠地捕捉精神病人格特质模型（PPTM）的四个维度。PPTS-R 的维度、结构效度和信度在普通（N = 1989）和监狱（N= 638) 人口。使用 Mplus 和 MLR 估计指定并测试了 PPTS-R 的三个竞争模型。目前的研究提供的证据表明，使用 5 点李克特量表的 28 项 PPTS-R 最好由四个因素来捕捉，包括情感反应性、认知反应性、人际交往和自我中心性，并且可以有效地用于法医和一般人群。此外，PPTS-R 将首次允许在法医和非法医人群之间就精神病特征的普遍性进行有意义的比较。
