Deviant peer affiliation predicts externalizing behavior in adolescence, but no research explores how having negative or suspicious expectations of others (i.e., distrust) may evoke or buffer against the relationship between deviant peer affiliation and externalizing behavior. The current study used data across two timepoints to investigate the impact of deviant peer affiliation and distrust on externalizing behavior 3 years later and whether race/ethnicity moderated this relationship. The sample consisted of 611 adolescents from the Project on Human Development in Chicago Neighborhoods Study (48% male; M_age = 15.5 years, SD = 1.6; 17% White; 34% Black; 49% Hispanic). Higher levels of distrust buffered against the influence of deviant peer affiliation on externalizing behaviors. Further, this buffering was evident in Black compared to White adolescents. Understanding externalizing behavior warrants considering the intersection between the person and their environment.

异常同伴关系可以预测青春期的外化行为，但没有研究探讨对他人的负面或可疑期望（即不信任）如何引起或缓冲异常同伴关系与外化行为之间的关系。目前的研究使用跨两个时间点的数据来调查不正常的同伴关系和不信任对 3 年后外化行为的影响，以及种族/民族是否缓和了这种关系。样本包括来自芝加哥社区人类发展项目研究的 611 名青少年（48% 男性；M_年龄 = 15.5 岁，SD = 1.6; 17% 白色；34% 黑色；49% 西班牙裔）。较高程度的不信任缓冲了越轨同侪关系对外化行为的影响。此外，与白人青少年相比，这种缓冲在黑人中很明显。理解外化行为需要考虑人与其环境之间的交叉点。
