A taxometric analysis of the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) was performed on a group of 2,250 male and female forensic/psychiatric patients and jail/prison inmates. The 4 PCL:SV facet scores (Interpersonal, Affective, Impulsive Lifestyle, Antisocial Behavior) served as indicators in this study, and the data were analyzed with 3 principal taxometric procedures--mean above minus below a cut, maximum eigenvalue, and latent mode factor analysis. The results show evidence of dimensional structure on the PCL:SV in the full sample as well as in all 8 subsamples (men, women, Whites, Blacks, hospital patients, jail/prison inmates, file review with an interview, file review without an interview). These findings corroborate recent taxometric research on the Psychopathy Checklist-Revised (R. D. Hare, 1991, 2003) in which results have been largely dimensional in nature. It is concluded that scores on the PCL:SV differ quantitatively as points on a dimension (high vs. low psychopathy) rather than partitioning into qualitatively distinct categories of behavior (psychopath vs. nonpsychopath).
对2250名男性和女性法医/精神病患者以及监狱囚犯进行了《精神病态量表：筛查版》（PCL:SV；S.D.哈特、D.N.考克斯和R.D.黑尔，1995年）的类属分析。本研究中，PCL:SV的4个方面得分（人际、情感、冲动生活方式、反社会行为）作为指标，并采用3种主要类属分析程序——均值高于减去低于切点、最大特征值和潜在模式因子分析对数据进行分析。结果显示，在整个样本以及所有8个子样本（男性、女性、白人、黑人、医院患者、监狱囚犯、有访谈的档案审查、无访谈的档案审查）中，PCL:SV都存在维度结构的证据。这些发现证实了近期对《修订版精神病态量表》（R.D.黑尔，1991年、2003年）的类属分析研究，其结果在很大程度上具有维度性质。研究得出结论，PCL:SV得分在维度上（高精神病态与低精神病态）存在数量差异，而非划分为性质不同的行为类别（精神病态者与非精神病态者）。
