Adolescent Cultural Identity Development in Context: The Dynamic Interplay of the Identity Project With Classroom Cultural Diversity Climate in Italy and Germany.

While both the classroom cultural diversity climate and curriculum-based interventions can promote cultural identity development, they have not been studied together. Drawing on theories of ethnic-racial identity development, the current study aimed to understand the dynamic interplay of a curriculum-based intervention (the Identity Project) with the classroom cultural diversity climate (heritage culture and intercultural learning, critical consciousness socialization and equal treatment) on cultural identity exploration and resolution. Our sample included 906 mid-adolescents in Italy (32.36% immigrant descent, Mage (SD) = 15.12 (0.68) years, 51.73% female), and 504 early adolescents in Germany (53.86% immigrant descent, Mage (SD) = 12.82 (0.89) years, 42.37% female). Bayesian multivariate linear models show that the Identity Project and a stronger critical consciousness climate in the classroom before the intervention promoted cultural identity exploration at post-test in both countries. However, effects of the intervention and facets of the diversity climate on subsequent resolution were only observed in Italy. There was some evidence that the intervention could alter the classroom cultural diversity climate in Germany, while the intervention could compensate for a less positive diversity climate in the slightly older sample in Italy. Thus, it seems promising to systematically build in opportunities to engage with students' diverse heritage cultures and identities when developing new curricula, as well as to train teachers to implement such curricula.

Promoting Adolescents' Heritage Cultural Identity Development: Exploring the Role of Autonomy and Relatedness Satisfaction in School-Based Interventions.

Given the significance of heritage cultural identity for optimal adolescent development, it is imperative to investigate factors influencing the efficacy of interventions aimed at promoting heritage cultural identity. Using latent profile cluster analysis and multinomial logistic regressions, this longitudinal study examined how autonomy and relatedness need satisfaction at school (1) related to heritage cultural identity development trajectories, and (2) moderated effects of a school-based intervention. The study included N = 198 adolescents (Mage = 12.86 years, SDage = 0.75, 52% female, 41% immigrant descent, 49% intervention group) in Germany. Teacher-student relationships played an important role in facilitating intervention effects on identity development trajectories, emphasizing the importance of the relational context when implementing school-based interventions to promote heritage cultural identity development.

Longitudinal Profiles of Cultural Identity Processes and Associations with Psychosocial Outcomes Among Adolescents Participating in the Identity Project in Italy.

Cultural identity formation is a complex developmental task that influences adolescents' adjustment. However, less is known about individual variations in trajectories of cultural identity processes and how they relate to youth psychosocial outcomes. Using a person-centered approach, this study investigated patterns of change over a year in cultural identity exploration and resolution, respectively, among ethnically diverse adolescents in Italy. The sample included 173 high school students (Mage = 15 yrs, SD = 0.62, range = 14-17; 58.4% female; 26% immigrant background) who had participated in the Identity Project, a school-based intervention targeting ethnic-racial identity development. Longitudinal latent profile analysis revealed only one profile of change for exploration, whereas four unique profiles for resolution emerged ("stable low," "stable average," "increase low-to-average," "increase high-to-higher"). Overall, youth in the resolution-increase profiles reported the best outcomes. The findings highlight the heterogeneity of adolescents' resolution trajectories and the benefits of an increased sense of clarity concerning one's cultural identity for positive psychosocial functioning.

Ethnic-Racial Identity and Attitude Change: Assessments of Outgroup and Diversity Attitudes among Adolescents in Sweden.

Outgroup and diversity attitudes are important components of intercultural understanding and well-being. Despite the potential of ethnic-racial identity development as a means to foster positive outgroup and diversity attitudes, little is known about its effectiveness in rapidly diversifying contexts such as Sweden. This pre-registered study filled this gap by examining if adolescents taking part in an intervention focused on ethnic-racial identity exploration, the Identity Project, also reported change in outgroup and diversity attitudes, and whether migration background, education type, and ethnic-racial identity development predicted such change. Twenty-three tenth-grade classes in Sweden (N = 509; Mage = 16.28; SDage = 0.80; 66% female; 51% migration background) participated in the intervention and were assessed in four waves over a period of 26 weeks. Whereas ethnic-racial identity exploration and resolution increased for the intervention group, the adolescents reported no change in outgroup and diversity attitudes when compared to a control group. Increases in ethnic-racial identity exploration and resolution co-varied with increases in attitudes, but only at Time 3. The results do not provide support for the link between ethnic-racial identity development and positive outgroup and diversity attitudes, and challenge the notion of attitude change as a cascading effect of the Identity Project intervention in non-US sociocultural contexts. All aspects of the study were pre-registered on the Open Science Framework platform ( https://osf.io/f5896 ).
