We studied the predictive, comparative, and incremental validity of three measures of psychopathic features (Psychopathy Checklist: Youth Version [PCL:YV]; Antisocial Process Screening Device [APSD]; Childhood Psychopathy Scale [CPS]) vis-à-vis criminal recidivism among 83 delinquent youth within a truly prospective design. Bivariate and multivariate analyses (Cox proportional hazard analyses) showed that of the three measures, the CPS was most consistently related to most types of recidivism in comparison to the other measures. However, incremental validity analyses demonstrated that all of the predictive effects for the measures of psychopathic features disappeared after conceptually relevant covariates (i.e., substance use, conduct disorder, young age, past property crime) were included in multivariate predictive models. Implications for the limits of these measures in applied juvenile justice assessment are discussed.
我们在一项真正前瞻性的设计中，研究了针对83名青少年犯罪者的三种精神病态特征测量方法（《精神病态量表：青少年版》[PCL:YV]；反社会过程筛查工具[APSD]；儿童精神病态量表[CPS]）相对于犯罪再犯的预测效度、比较效度和增量效度。双变量和多变量分析（Cox比例风险分析）表明，在这三种测量方法中，与其他方法相比，CPS与大多数类型的再犯最为一致地相关。然而，增量效度分析表明，在多变量预测模型中纳入概念上相关的协变量（即物质使用、品行障碍、年龄较小、过去的财产犯罪）后，精神病态特征测量方法的所有预测效应均消失。本文讨论了这些测量方法在应用于青少年司法评估时的局限性。
