This study evaluated the reliability, internal structure, and validity of the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) among female inmates (n = 153) housed at a multilevel prison facility. Findings from this research suggested both strengths and weaknesses associated with PPI psychopathy assessment. Reliability of the PPI was supported by internal consistency analyses of scale and subscale item sets, and test-retest reliability was supported by findings obtained with a subsample (n = 36) retested an average of 49 days after initial test administration. Validity of the PPI total score was also supported by moderate to very high correlations with other self-report measures of psychopathy. Relative weaknesses of the PPI were evident by the low or negative associations among many of the PPI subscales, moderate associations that PPI total scores demonstrated with response set indexes, and the similarity of PPI total scores among female inmates and undergraduates. Findings from this research are considered in relation to possible sex differences in the expression of psychopathy and challenges associated with the assessment of the psychopathy construct with self-report methods.
本研究评估了心理变态人格问卷（PPI；Lilienfeld & Andrews，1996）在一所多层监狱设施中关押的女性囚犯（n = 153）中的信度、内部结构和效度。该研究结果表明了与PPI心理变态评估相关的优势和不足。PPI的信度通过量表和子量表项目集的内部一致性分析得到支持，重测信度通过对一个子样本（n = 36）在首次测试后平均49天进行重测所得结果得到支持。PPI总分的效度也通过与其他心理变态自评量表的中度到非常高的相关性得到支持。PPI的相对不足表现为许多PPI子量表之间的低关联或负关联、PPI总分与反应定势指标的中度关联，以及女性囚犯和大学生的PPI总分相似性。本研究结果结合心理变态表现中可能存在的性别差异以及使用自评方法评估心理变态结构所面临的挑战进行了考量。
