The aim of the current study was to further examine the psychometric properties of the Expanded Levenson Self-Report Psychopathy Scale (E-LSRP; Christian & Sellbom, 2016). Specifically, its reliability, internal structure, and convergent and discriminant validity were evaluated using university (N = 367) and community samples (N = 205) from Aotearoa New Zealand. The results provided support for the reliability and validity of the E-LSRP in both samples. More specifically, the internal consistency estimates of the E-LSRP were above the meaningful threshold, indicating good reliability. Furthermore, using confirmatory factor analysis, the hypothesized three-factor structure was supported and conceptually consistent with Cooke and Michie’s (2001) Psychopathy Checklist-Revised (PCL-R) three-factor model. Lastly, the results generally provided support for the convergent and discriminant validity of the E-LSRP subscales; the E-LSRP Egocentricity was associated with criteria relevant to interpersonal impairment, the Callous scale with criteria relevant to the affective psychopathy domain, and the Antisocial scale with criteria representing behavioral dysfunction. Overall, the E-LSRP is a promising tool for assessing psychopathy in nonincarcerated populations.

本研究的目的是进一步检验扩展 Levenson 精神病态自我报告量表 (E-LSRP; Christian & Sellbom, 2016) 的心理测量特性。具体而言，其可靠性、内部结构以及收敛和区分有效性是使用大学 ( N = 367) 和社区样本 ( N= 205) 来自新西兰 Aotearoa。结果为两个样本中 E-LSRP 的可靠性和有效性提供了支持。更具体地说，E-LSRP 的内部一致性估计值高于有意义的阈值，表明具有良好的可靠性。此外，使用验证性因素分析，假设的三因素结构得到支持，并且在概念上与 Cooke 和 Michie (2001) 修订的精神病检查表 (PCL-R) 三因素模型一致。最后，结果普遍支持 E-LSRP 分量表的收敛效度和判别效度；E-LSRP 自我中心性与人际关系障碍相关标准相关，Callous 量表与情感精神病领域相关标准相关，而 Antisocial 量表与行为功能障碍相关标准相关。全面的，
