Language identity, an understudied factor, can influence isolation and discrimination, leading to disparities in well-being and mental health among immigrants. This study aims to investigate the role of language identity on structural racism and discrimination among 1.5 generation Asian/Asian American immigrants in a diverse U.S. state. We developed a three-step sequential approach: Stage 1—qualitative analysis (1A, focus group discussion; 1B, in-depth interviews); Stage 2—quantitative analysis (2A, language identity measurement scale; 2B, cross-sectional online survey; 2C, multivariate multiple linear regression); Stage 3—another round of qualitative analysis (3A, follow-up in-depth chronological interviews). Therefore, this study will contribute to the field by introducing a novel three-step mixed methods approach, marking a notable improvement over conventional explanatory or exploratory sequential designs.
