To examine the unique functions of same- and cross-ethnic friendships, Latino (n = 536) and African American (n = 396) sixth-grade students (Mage = 11.5 years) were recruited from 66 classrooms in 10 middle schools that varied in ethnic diversity. Participants reported on the number of same- and cross-ethnic friends, perceived vulnerability, friendship quality, and the private regard dimension of ethnic identity. Whereas same-ethnic friendships were uniquely associated with stronger private regard, more ethnic diversity and cross-ethnic friendships were uniquely associated with less perceived vulnerability. Multilevel structural equation modeling tested whether cross-ethnic friendships mediated the diversity-vulnerability relation. Although cross-ethnic friendships did not significantly mediate this relation at the classroom level, these friendships predicted less vulnerability at the individual student level.
为了探究同种族和跨种族友谊的独特功能，研究招募了来自 10 所中学 66 个班级的 536 名拉丁裔和 396 名非裔美国六年级学生（平均年龄为 11.5 岁）。参与者报告了同种族和跨种族朋友的数量、感知脆弱性、友谊质量以及种族认同的私人关注维度。同种族友谊与更强的私人关注有关，而更多的跨种族友谊与更少的感知脆弱性有关。多层次结构方程模型检验了跨种族友谊是否在班级层面中介了多样性与脆弱性的关系。尽管跨种族友谊在班级层面并没有显著中介这种关系，但这些友谊在个体学生层面预测了较低的脆弱性。
