Ethnic identity is a major area of study across many disciplines including psychology, sociology, anthropology, and political science. Yet, little is known about changes in ethnic identity across the adult lifespan, and whether such changes are driven by normal aging processes (aging effects), unique societal influences linked with one's formative years (cohort effects), or social changes during a specific time frame (period effects). We address these key oversights by utilizing 13 annual waves of longitudinal panel data from a nationwide random sample of both ethnic majority ( = 49,660) and Indigenous ethnic minority ( = 8,325) group members in New Zealand to examine changes in ethnic identity centrality using cohort-sequential latent growth modeling. This approach helps to identify changes in mean levels of ethnic identity centrality over time and whether such changes are driven by aging, cohort, and/or period effects. Our data reveal that, among both ethnic majority and ethnic minority individuals, changes in ethnic identity centrality were informed by a combination of normative aging processes, societal circumstances that reflected the unique historical context in which people grew to maturity, and societal changes during the 13 annual assessments of our study. Collectively, these results demonstrate for the first time that ethnic identity centrality in adulthood is subject to lifelong changes. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
民族认同是心理学、社会学、人类学和政治学等多个学科的主要研究领域之一。然而，人们对成年期民族认同的变化知之甚少，也不知道这些变化是由正常的衰老过程（衰老效应）、与一个人成长时期相关的独特社会影响（队列效应）还是特定时间段内的社会变化（时期效应）驱动的。我们利用新西兰全国范围内随机抽取的多数族裔（n=49660）和原住民少数民族（n=8325）成员的 13 年纵向面板数据的 13 个年度波次的纵向面板数据，通过队列序列潜在增长建模来研究民族认同核心度的变化，从而解决了这些关键的忽视问题。这种方法有助于确定民族认同核心度随时间的变化以及这些变化是否是由衰老、队列和/或时期效应驱动的。我们的数据表明，在多数族裔和少数民族个体中，民族认同核心度的变化受到正常衰老过程、反映人们成熟时期独特历史背景的社会环境以及我们研究的 13 次年度评估期间的社会变化的共同影响。总的来说，这些结果首次表明，成年期的民族认同核心度是受到终身变化影响的。
