Reliability and construct validity of the Psychopathic Personality Inventory-Revised in a Swedish non-criminal sample: a multimethod approach including psychophysiological correlates of empathy for pain

Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R’s reliability, construct validity and factor structure in non-criminal individuals (N = 227) in Sweden, using a multimethod approach including psychophysiological correlates of empathy for pain. PPI-R construct validity was investigated in subgroups of participants by exploring its degree of overlap with (i) the Psychopathy Checklist: Screening Version (PCL:SV), (ii) self-rated empathy and behavioral and physiological responses in an experiment on empathy for pain, and (iii) additional self-report measures of alexithymia and trait anxiety. The PPI...针对精神病态（psychopathy）测评工具开展跨文化研究，对于厘清围绕精神病态构念的法则性网络（nomological network）具有重要学术价值。修订版精神病态人格量表（Psychopathic Personality Inventory-Revised, PPI-R）是当前成人精神病态特质自陈量表中研究最为广泛深入的工具之一。然而截至目前，相关实证研究主要聚焦于北美罪犯与学生群体样本。为填补该领域的研究空白，本研究以瑞典非犯罪群体（N=227）为被试，采用包含疼痛共情心理生理关联指标的多方法研究范式，考察了PPI-R的信度、结构效度与因子结构。本研究通过探索PPI-R与以下三类工具的重合程度，在被试亚组中验证了其结构效度：(i) 《精神病态检查表：筛查版》（Psychopathy Checklist: Screening Version, PCL:SV）；(ii) 疼痛共情实验中的自我报告共情评分、行为与生理反应；(iii) 述情障碍（alexithymia）与特质焦虑（trait anxiety）的其他自陈量表。本研究对PPI……
