The aim of the current study is to examine the psychometric properties of the German Version of the Youth Psychopathic traits Inventory-Short Version (YPI-S).
A sample of 856 adolescents (age: 15-19) from the German-speaking part of Switzerland was included. All participants completed the 50-item YPI, of which we derived the 18 items of the YPI-S. Furthermore, participants completed the Massachusetts Youth Screening Instrument-Version-2 (MAYSI-2), as well a self-report delinquency questionnaire.
We were able to replicate a three-factor structure and found moderate to good internal consistency for the total score as well as for the three dimensions of the YPI-S. Measurement invariance across gender was established. Furthermore, we found positive small to medium correlations with both internalizing and externalizing mental health problems, substance abuse problems, and offending behavior.
Our results suggest that the German version of the YPI-S is a reliable and valid screening instrument for psychopathic traits in both boys and girls from the general population in the German-speaking part of Switzerland.
本研究旨在检验德文版青少年心理病理特质问卷-短式版（YPI-S）的心理计量特性。
研究纳入了来自瑞士德语区的 856 名青少年（年龄：15-19 岁）。所有参与者均完成了 50 项 YPI，其中我们得出了 YPI-S 的 18 项。此外，参与者还完成了马萨诸塞州青少年筛查工具-第二版（MAYSI-2）以及一份自我报告的犯罪问卷。
我们成功复制了三因素结构，发现 YPI-S 的总分以及三个维度均具有中等至良好的内部一致性。在性别方面，测量的不变性得以确立。此外，我们发现 YPI-S 与内化和外化的心理健康问题、药物滥用问题以及犯罪行为呈正相关，相关程度为小到中等。
研究结果表明，德文版 YPI-S 是瑞士德语区普通人群中男孩和女孩心理病理特质的一种可靠和有效的筛查工具。
