The Youth Psychopathic Traits Inventory (YPI) is widely used in research, but there currently exist no means to identify potentially invalid protocols resulting from careless or random responding. We describe the development of an inconsistent responding scale for the YPI using three archival samples of youths, including two from the United States (juvenile justice and middle school) and one from Germany (vocational training school). We first identified pairs of correlated YPI items and then created a total score based on the sum of the absolute value of the differences for each item pair. The resulting scale strongly differentiated between genuine protocols and randomly generated YPI data (n = 1,000) across samples (AUC values = .88-.92). It also differentiated between genuine protocols and those same protocols after 50% of the original YPI items were replaced with random data (AUCs = .77-.84). Scores on this scale also demonstrated fairly consistent patterns of association with theoretically relevant correlates.
青少年精神变态特质问卷（YPI）在研究中被广泛应用，但目前还没有办法识别由于粗心或随机反应导致的潜在无效协议。我们使用三个青少年档案样本描述了一种用于 YPI 的不一致反应量表的开发，其中两个来自美国（少年司法和中学），一个来自德国（职业培训学校）。我们首先确定了相关的 YPI 项目对，然后根据每个项目对的差异绝对值之和创建了一个总分。该量表在样本（AUC 值为.88-.92）之间很好地区分了真实协议和随机生成的 YPI 数据。它还区分了真实协议和在原始 YPI 项目的 50%被随机数据替换后的协议（AUC 值为.77-.84）。该量表的分数也与理论上相关的指标表现出相当一致的关联模式。
