Barriers to accessing mental health care for refugees and asylum seekers in high-income countries: A scoping review of reviews mapping demand and supply-side factors onto a conceptual framework

This study undertakes a scoping review of reviews on barriers to accessing mental health care for refugees and asylum seekers in high-income countries. By assessing mental health care access using the Levesque's conceptual framework, we identify barriers along the patient care pathway and highlight research gaps. Following PRISMA-ScR guidelines, 10 relevant systematic and scoping reviews were identified and analyzed. Seven common barriers were identified, that could be located across different stages of the conceptual framework. Demand-side barriers included: (1) refugees' understanding of mental illness, (2) fear of stigma, (3) lack of awareness of services, (4) attitudes towards formal treatment; while supply-side barriers comprised: (5) language barriers, (6) practical and structural issues, and (7) providers' attitudes and competence. There was a focus on demand-side barriers as key determinants for low service use. We observed a paucity of quantitative studies linking barriers and indicators of access to care. In the context of well-established mental health care systems, previous research has largely explained low access through peculiarities of refugees and asylum seekers, thereby neglecting the role of supply-side factors (including system structures and attitudes of service providers). We discuss how future research can critically question prevailing assumptions and contribute to rigorous evidence.
