Ethnic socialization and ethnic identity development among internationally adopted Korean American adolescents: A seven-year follow-up.

ABSTRACT: The relationship between ethnic socialization by parents, peers, and ethnic identity development was examined over a 7-year time span in a sample of 116 internationally adopted Korean American adolescents. Parent report data was collected in 2007 (Time 1 [T1]) when the adopted child was between 7 and 13 years old and again in 2014 at ages 13 to 20 years old (Time 2 [T2]). Adolescent report data also was collected in 2014. We examined differences in parent and adolescent reports of parental ethnic socialization at T2, changes in parent reports of ethnic socialization from T1 to T2, and the relationship among ethnic socialization by parents at T1 and T2, ethnic socialization by peers at T2, and ethnic identity exploration and resolution at T2. Results indicated parents reported higher levels of parental ethnic socialization than adolescents did at T2. Parent reports of parental ethnic socialization also decreased between childhood and adolescence. Adolescents reported higher parental ethnic socialization than peer ethnic socialization at T2. Path analysis demonstrated positive indirect pathways among parental ethnic socialization at T1, parental ethnic socialization and peer ethnic socialization at T2, and ethnic identity exploration and ethnic identity resolution at T2. The study highlights the cultural experiences of transracial, transnational adopted individuals, the role of both parents and peers in ethnic socialization and ethnic identity development, and the importance of longitudinal and multi-informant methodology.

Project description:The developing immune system is an adaptive system, primed by antigens, responsive to infectious pathogens, and can be affected by other aspects of the early rearing environment, including deviations from the normal provision of parental care. We investigated whether early rearing in an institutional setting, even when followed by years living in supportive and well-resourced families, would be associated with a persistent shift in T cell profiles. Immunophenotyping was used to enumerate CD4+ CD57+ and CD8+ CD57+ subsets, with gating strategies employed to differentiate naïve, central-memory, effector-memory, and terminally differentiated EM cells expressing CD45RA (TEMRA). Blood samples were collected from 96 adolescents, and PBMC isolated via Ficol gradient, followed by an optimized immunophenotypic characterization. CMV antibody titers were determined via ELISA. Adopted adolescents had lower CD4/CD8 ratios than did the control adolescents. Early rearing had a significant effect on the T cells, especially the CD8+ CD57+ CM, EM, and TEMRA cells and the CD4+ CD57+ EM cells. Adolescents who had spent their infancy in institutions before adoption were more likely to be seropositive for CMV, with higher antibody titers. CMV antibody titers were significantly correlated with the percentages of all CD8+ CD57+ cell subsets. In the statistical modeling, CMV antibody titer also completely mediated the relationship between institutional exposure and the ratio of CD4-to-CD8 cells, as well as the percentages of CD4+ CD57+ and CD8+ CD57+ subsets. These findings demonstrate that persistent immune differences are still evident even years after adoption by supportive American families. The shift in the T cells was associated with being a latent carrier of CMV and may reflect the role of specific T cell subsets in Herpes virus containment. In older adults, sustained CMV antigen persistence and immunoregulatory containment ultimately contributes to an accumulation of differentiated T cells with a decreased proliferative capacity and to immune senescence.
