This study examined the links among Chinese American adolescents’ (N= 96) global ethnic identity and their ethnic behaviors, ethnic identity salience, and psychological well–being based on daily diaries collected over a 2–week period. The daily association between engagement in ethnic behaviors and ethnic salience was positive regardless of overall ethnic identity. The daily–level association between ethnic identity salience and well–being, however, was dependent on adolescents’ global ethnic identity. Among adolescents who were moderate or high in global ethnic identity, ethnic identity salience was consistently associated with positive well–being at the daily level. In contrast, the daily association between ethnic identity salience and well–being was less strong for youths who were low in ethnic identity. Additionally, a higher level of salience and a weaker association between salience and negative symptoms was found for girls than for boys, and older youths reported a weaker association between salience and positive symptoms than did younger youths.
