Background. Research indicates the adverse impacts of perceived discrimination on health, and discrimination inflamed by the COVID-19 pandemic, a type of social exclusion, could affect the well-being of the Chinese diaspora. The relationship and pathways of perceived discrimination’s effect on health among the Chinese diaspora in the context of the pandemic were examined to contribute to the literature on discrimination in this population under the global public health crisis.Methods. We analysed data from 705 individuals of Chinese descent residing in countries outside of China, who participated in a cross-sectional online survey carried out between April 22 and May 9, 2020. This study utilizes a structural equation model (SEM) to evaluate both direct and indirect effects of perceived discrimination on self-rated health (SRH) and assessed the mediating roles of psychological distress (namely, anxiety and depression) and social support from family and friends. Results. In this online sample comprised predominantly of young adults and those of relatively high socioeconomic status, this study confirmed the positive and direct effect of perceived discrimination on poor SRH but found the indirect effect was mainly mediated by depression. The association between anxiety and SRH was not significant in this SEM, while a higher level of social support from family leads to better SRH, and the level of social support from friends negatively predicted SRH. Conclusions. Our findings suggest discrimination negatively affected the well-being of the Chinese diaspora, and depression acted as a major mediator between the discrimination-health relationship. Therefore, interventions for reducing discrimination in order to preserve the well-being of the Chinese diaspora are necessary, and that prompt intervention to address depression may partially relieve the disease burden caused by the surge of discrimination.
