Objectives: In response to increased anti-Asian discrimination and violence during the COVID-19 pandemic, this study examined pathways from discrimination experiences to own-group collective action in a diverse sample of 689 Asian Americans. Method: Informed by theories of ethnoracial identity, critical consciousness, and collective action and utilizing structural equation modeling, we examined the associations among discrimination, psychological distress, critical awareness and motivation (CAM) to resist racism, and two types of own-group collective action: political activism and benevolent support. Multigroup invariance tests also examined whether these associations differed by ethnic subgroup, immigrant generation, and age. Results: Results supported our integrated model in which distress mediated the relationship between discrimination and CAM, and CAM mediated the relationship between discrimination and collective action. The structural pathways from discrimination to own-group collective action generally did not differ by ethnic subgroup and immigrant generation, although path coefficients for the effect of discrimination on distress did vary by age (p <.01). Further, discrimination did not appear to have the same catalyzing effect on CAM for South and Southeast Asians compared to East Asians. Conclusions: While anti-Asian discrimination was associated with both distress and engagement in collective action during the COVID-19 pandemic, group differences in mediational processes highlight the importance of disaggregating analyses to explore both similarities and differences in Asian Americans' responses to discrimination. Public Significance Statement: This study found that among Asian Americans, exposure to discrimination during the COVID-19 pandemic was associated with greater awareness and motivation to resist racism, which in turn was associated with greater activism and aid in support of Asian Americans. At the same time, discrimination was also associated with psychological distress, which was associated with increased awareness and motivation to resist racism among East Asians, but not for South or Southeast Asians. Results suggest that distress may reflect, in part, a process of "awakening" to the reality of racism for East Asians during the pandemic, highlighting the importance of disaggregating analyses to explore both similarities and differences in Asian Americans' responses to discrimination.
