两个自我报告的精神病，Levenson的主要和次要精神病量表（LPSP）和精神病态人格量表（PPI）的措施，管理的大样本的1,603名罪犯。最广泛的研究措施的刑事精神病，野兔精神病检查表修订版（PCL-R），作为一个临时的参考估计这些自我报告的措施与罪犯的结构效度。与LPSP相比，PPI与PCL-R的零阶相关性更高，收敛效度和判别效度更好，预测PCL-R评分的增量效用更一致。此外，使用Westen和Rosenthal的方法的变体来评估一个新的措施的结构效度，与LPSP相比，PPI与35个外部标准变量的测量的关联模式更类似于PCL-R观察到的模式。结果一般提供更强有力的支持PPI的有效性比LPSP在罪犯人群中使用的PCL-R作为临时基准，特别是用于评估精神病的人际和情感特征。
Two self-report measures of psychopathy, Levenson's Primary and Secondary Psychopathy scales (LPSP) and the Psychopathic Personality Inventory (PPI), were administered to a large sample of 1,603 offenders. The most widely researched measure of criminal psychopathy, the Hare Psychopathy Checklist Revised (PCL-R), served as a provisional referent for estimating the construct validity of these self-report measures with offenders. Compared with the LPSP, the PPI displayed higher zero-order correlations with the PCL-R, better convergent and discriminant validity, and more consistent incremental utility in predicting PCL-R scores. Furthermore, using a variant of Westen and Rosenthal's approach to evaluating the construct validity of a new measure, compared with the LPSP, the PPI's pattern of associations with measures of 35 external criterion variables was more similar to the pattern observed for the PCL-R. Results generally provide stronger support for the validity of the PPI than the LPSP in offender populations using the PCL-R as a provisional benchmark, particularly for assessing interpersonal and affective features of psychopathy.
