我们评估的有效性和稳定性，瑞典开发的青年精神病特质量表（YPI; Andershed，克尔，Stattin，Levander，2002年）在加拿大非法医年轻人。在研究1中，共有217名大学生完成了YPI以及精神病态人格量表修订版（PPI-R; Lilienfeld Widows，2005）和Levenson自我报告精神病量表（LSRP; Levenson，Kiehl，菲茨帕特里克，1995）。这些措施完成了两次，两次给药之间平均间隔28天。总YPI与PPI-R密切相关，但也与LSRP分量表密切相关。YPI高阶维度与内容相似的PPI-R维度有意义地相关。YPI产生了相当高的时间稳定性，并类似于PPI-R和LSRP原发性精神病量表。在研究2中，我们使用了111名大学生，发现YPI与反社会态度和冲动性呈正相关，与宜人性和友好性呈负相关。这项研究扩展了YPI的有效性从青少年到加拿大的年轻人从nonforensic设置。鉴于其承诺作为衡量青少年和年轻人的精神病特征，YPI可能被证明是有用的，在这些发展时期的纵向研究。
We assessed the validity and stability of the Swedish developed Youth Psychopathic Traits Inventory (YPI; Andershed, Kerr, Stattin, Levander, 2002) in Canadian nonforensic young adults. In Study 1, a total of 217 undergraduates completed the YPI as well as the Psychopathic Personality Inventory-Revised (PPI-R; Lilienfeld Widows, 2005) and the Levenson Self-Report Psychopathy Scale (LSRP; Levenson, Kiehl, Fitzpatrick, 1995). These measures were completed twice, with a mean of 28 days between administrations. Total YPI was strongly correlated with the PPI-R but also with the LSRP subscales. YPI higher order dimensions were meaningfully correlated with PPI-R dimensions of similar content. The YPI yielded fairly high temporal stability and was similar to the PPI-R and LSRP Primary Psychopathy scale. Using 111 undergraduates, in Study 2, we found the YPI was positively associated with antisocial attitudes and impulsivity and negatively associated with agreeableness and conscientiousness. This research extends the validity of the YPI beyond adolescents to Canadian young adults from nonforensic settings. Given its promise as a measure of psychopathic traits in adolescents and young adults, the YPI may prove useful in longitudinal research across these developmental periods.
