The Youth Psychopathic Traits Inventory-Short Form (YPI-S) is a convenient measure for assessing psychopathy in settings with constraints on resources. However, the YPI-S does not contain a means of detecting careless or random response styles. The present study describes the development and evaluation of an inconsistent responding scale for the YPI-S using five archival samples that vary in language (English, German, Italian, Dutch) and other participant characteristics (juvenile offenders, adolescent students). Inconsistency scores resulting from the new scale effectively distinguished genuine participant responses from randomly generated cases (area under the ROC curve [AUC] = .85-.90) and from cases in which 50% of original responses were replaced with random data (AUC = .75-.82). The associations between the YPI-S and theoretically relevant correlates were reduced among participants exceeding proposed cutoff scores for profile validity compared with associations among more consistent respondents.
青少年精神变态特质问卷-简式（YPI-S）是一种在资源有限的情况下评估精神变态的便捷方法。然而，YPI-S 并没有包含检测粗心或随机反应模式的方法。本研究使用五个不同语言（英语、德语、意大利语、荷兰语）和其他参与者特征（少年犯、青少年学生）的档案样本，描述了 YPI-S 中不一致反应量表的开发和评估。新量表产生的不一致分数有效地将真实参与者的反应与随机生成的案例区分开来（ROC 曲线下面积 [AUC] =.85-.90），也与将 50%的原始反应替换为随机数据的案例区分开来（AUC =.75-.82）。与更一致的参与者相比，在超过拟议的特征有效性临界值的参与者中，YPI-S 与理论上相关的相关性之间的关联减少。
