Values and national identity of adolescents in China: the chain mediating effect of core self-evaluations and identity motivation

National identity is at the core of the individual identity system. In the context of globalization, influenced by the intertwining of multiple cultures and values, the alignment of self and national values not only affects Chinese adolescents' self-concept but also concerns the realization of national identity. To investigate the influencing factors and mechanisms that affect adolescents' national identity in China, this study measured 1004 adolescents using the National Identity Scale, Schwartz Value Survey, Core Self-Evaluation Scale, and Identity Motivation Scale, and found that (1) adolescents' overall level of national identity was high; (2) adolescents' values, core self-evaluation, and identity motivation were positively related to national identity; (3) values significantly and positively predict national identity; and (4) core self-evaluation and identity motivation played a chain mediating role between values and national identity. The study suggests that adolescents' positive self-evaluation and identity motivation contribute to the enhancement of national identity. The future cultivation of national identity could focus on the development of values, personality, and identity motivation at the adolescent stage.
