本研究考察了 13 岁时使用母亲报告的儿童精神病量表（D. R. Lynam，1997）评估的精神病与 24 岁时使用访谈者评定的精神病检查表：筛选版本（PCL:SV；S. D. Hart、D. N. Cox 和 R. D. Hare，1995）评估的精神病之间的关系。匹兹堡青年研究中间样本的 250 多名参与者的数据被用来检验这种关系；大约 9% 的样本符合可能的 PCL:SV 诊断标准。尽管存在较长的时间滞后、不同的来源和不同的方法，但从青春期早期到成年早期的精神病态是中等稳定的（r = .31）。 PCL:SV 总分和方面评分存在这种关系，不受初始风险状态或初始精神病水平的调节，甚至在控制其他 13 岁变量后也保持这种关系。诊断稳定性稍低。特异性和阴性预测力均良好，敏感性足够，但阳性预测力较差。这是首次证明精神病从青春期到成年的相对稳定性，并为青少年精神病构造的增量效用提供了证据。讨论了影响和未来的方向。
This study examined the relation between psychopathy assessed at age 13 by using the mother-reported Childhood Psychopathy Scale (D. R. Lynam, 1997) and psychopathy assessed at age 24 by using the interviewer-rated Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995). Data from over 250 participants of the middle sample of the Pittsburgh Youth Study were used to examine this relation; approximately 9% of the sample met criteria for a possible PCL:SV diagnosis. Despite the long time lag, different sources, and different methods, psychopathy from early adolescence into young adulthood was moderately stable (r = .31). The relation was present for the PCL:SV total and facet scores, was not moderated by initial risk status or initial psychopathy level, and held even after controlling for other age 13 variables. Diagnostic stability was somewhat lower. Both specificity and negative predictive power were good, and sensitivity was adequate, but positive predictive power was poor. This constitutes the first demonstration of the relative stability of psychopathy from adolescence into adulthood and provides evidence for the incremental utility of the adolescent psychopathy construct. Implications and future directions are discussed.
