Ethnic identity refers to how individuals perceive and experience themselves in the context of social groups, racial background, or culture (Phinney & Ong., 2007). Ethnic identity is positively associated with psychological well-being (Rivas-Drake et al., 2014) and negatively associated with depression and anxiety (Forstmeier et al., 2021). Those with strong ethnic identity may display resiliency to the negative effects of discrimination on psychological well-being (Urzúa et al., 2021). Phinney's model describes four profiles for how people put effort into, participate in, and reflect upon their ethnic identity (Phinney, 1989). Despite prior work addressing ethnic identity and psychosocial outcomes (for review, see Meca et al., 2023), few studies have considered its neurobiological underpinnings. In the current study, we identified profiles of ethnic identity among participants in The Adolescent Brain Cognitive Development Study (ABCD Study) using latent profile analysis. Next, we examined resting state functional connectivity differences across observed profiles and assessed the moderating effects of perceived discrimination. Results indicated heightened cingulo-parietal (CPAR) network connectivity among adolescents with highly diffuse ethnic identities; among moderately achieved ethnic identities, perceived discrimination moderated the association between ethnic identity and CPAR connectivity. We discuss how these findings may be related to attentional shift, error monitoring, autobiographical memory, and social judgements.
族群认同是指个体如何在社会群体、种族背景或文化背景下看待和体验自己（菲尼 & 翁，2007年）。族群认同与心理健康呈正相关（里瓦斯 - 德雷克等人，2014年），与抑郁和焦虑呈负相关（福斯特迈尔等人，2021年）。具有强烈族群认同的人可能对歧视对心理健康的负面影响表现出复原力（乌尔祖亚等人，2021年）。菲尼的模型描述了人们在投入、参与和反思其族群认同方面的四种类型（菲尼，1989年）。尽管先前有研究探讨了族群认同与心理社会结果（综述见梅卡等人，2023年），但很少有研究考虑其神经生物学基础。在本研究中，我们使用潜在类别分析确定了青少年大脑认知发展研究（ABCD研究）参与者中的族群认同类型。接下来，我们检查了观察到的类型之间的静息态功能连接差异，并评估了感知到的歧视的调节作用。结果表明，具有高度分散族群认同的青少年的扣带回 - 顶叶（CPAR）网络连接增强；在中等程度实现族群认同的青少年中，感知到的歧视调节了族群认同与CPAR连接之间 的关联。我们讨论了这些发现可能如何与注意力转移、错误监测、自传体记忆和社会判断相关。
