Experience of discrimination during COVID-19 pandemic : the impact of public health measures and psychological distress among refugees and other migrants in Europe

Background: The COVID-19 pandemic has had a disproportionately hard impact on refugees and other migrants who are often exposed to the virus with limited means to protect themselves. We tested the hypothesis that during the COVID-19 pandemic, refugees and other migrants have suffered a negative impact on mental health and have been unjustly discriminated for spreading the disease in Europe (data collection from April to November 2020). Methods: Participants in the ApartTogether Survey (N = 8297, after listwise deletion of missing items final N = 3940) provided data regarding to their difficulties to adhere to preventive recommendations against COVID-19 infection (CARE), self-perceived stigmatization (SS), and psychological distress (PD). Structural Equation Modeling was used to investigate PD as a mediator in the pathway linking CARE to SS, while adjusting for the housing and residence status. To improve confidence in the findings, single hold-out sample cross-validation was performed using a train/test split ratio of 0.8/0.2. Results: In the exploratory set (N = 3159) SS was associated with both CARE (B = 0.200, p < 0.001) and PD (B = 0.455, p < 0.001). Moreover, PD was also associated with CARE (B = 0.094, p = 0.001) and mediated the effect of CARE on SS (proportion mediated = 17.7%, p = 0.001). The results were successfully replicated in the confirmation set (N = 781; total effect = 0.417, p < 0.001; proportion mediated = 29.7%, p < 0.001). Follow-up analyses also found evidence for an opposite effect (i.e., from SS to CARE, B = 0.132; p < 0.001), suggesting that there might be a vicious circle between the self-perceived stigmatization and the access to health care and the use of preventive measures against COVID-19 infection. Conclusions: Refugees and other migrants who had more difficulties in accessing health care and preventive measures against COVID-19 infection experienced worse mental health and increased discrimination.
