In this introduction to the special issue on diverse methods for cultural identity, we begin by addressing the evolving complexities of defining oneself amidst modern globalization and immigration. We then preview the current collection of papers, which collectively showcase the complexity of cultural identity by exploring how people, especially adolescents and young adults, navigate a plethora of cultural influences—whether through direct migration or the pervasive impact of global cultures—as they psychologically manage diverse and sometimes conflicting allegiances and worldviews. The studies featured in this issue employ a range of methodologies, from qualitative analyses to mixed-methods approaches, to expand our knowledge of the constitution of contemporary cultural identities beyond common quantitative metrics of self-categorization and group belongingness. For instance, research on Jamaican American adolescents highlights how cultural identity is formed through reciprocal socialization processes and systemic factors such as racism. Similarly, studies involving Hmong American youth and Guatemalan adolescents reveal tensions and creative harmonizations in identity management, challenging notions of a homogenized global culture. We conclude by underscoring the need for future research to take a nuanced, intersectional approach to the study of cultural identity, to explore creative measurement tools that are sensitive to local meaning-making among diverse groups around the world, and to attend to the impact of power dynamics in shaping one’s sense of self in relation to their cultural group(s).
