Religious-minority immigrants must negotiate both their religious and host cultural (e.g., American) identities; however, the duality of these identities is rarely examined in relation to adjustment. In this study, we tested whether a religious-American identity centrality could predict better adjustment over and above religious identity centrality and American identity centrality. Moreover, based on the Integrative Psychological Model of Biculturalism, we investigated whether the harmony perceived between one’s religious and American identities could mediate the relationship between religious-American identity centrality and adjustment, and between perceived discrimination and adjustment. With data from 130 first-generation Muslim American and Jewish American participants, we found support for most hypotheses. Although a more central religious-American identity predicted better adjustment, it did not predict better adjustment over and above religious identity centrality and American identity centrality. More importantly, religious-American harmony mediated the positive association between religious-American identity centrality and adjustment, and the negative association between perceived discrimination and adjustment. Implications of our findings for research on dual identities are discussed.

宗教少数族裔移民必须就其宗教身份和东道国文化（例如美国）身份进行谈判；但是，这些身份的双重性很少与调整有关。在这项研究中，我们测试了美国宗教信仰中心地位是否可以预测比宗教身份中心地位和美国身份中心地位更好的调整。此外，基于双文化主义的综合心理模型，我们调查了一个人的宗教身份与美国身份之间的和谐感是否可以介导宗教-美国身份中心性与适应性之间以及感知到的歧视与适应性之间的关系。根据130位第一代美国穆斯林和犹太裔美国人的数据，我们发现了大多数假设的支持。尽管一个更中央的宗教美国人身份预示着更好的调整，但它并没有预示除了宗教身份中心和美国身份中心以外的更好的调整。更重要的是，美国宗教信仰和睦相处介导了美国宗教信仰认同中心和调整之间的正向联系，以及感知到的歧视与调整之间的负相关。讨论了我们的发现对双重身份研究的意义。以及歧视和调整之间的消极关联。讨论了我们的发现对双重身份研究的意义。以及歧视和调整之间的消极关联。讨论了我们的发现对双重身份研究的意义。
