According to the UN Refugee Agency data, at the end of 2020, 82.4 million people were forcibly displaced worldwide due to persecution, conflict, violence, human rights violations, or events seriously disturbing public order (UNHCR, 2021). Many of them are refugees (26.4 million), and about half were under the age of 18. At the end of 2019, approximately 10% of all refugees lived in the EU, which amounts to 0.6% of the EU population (European Commission, 2021). In total, there were 2.6 million refugees in Europe until the end of 2019.As refugees are frequently exposed to traumatic experiences before, during, or after fleeing, they represent a particularly vulnerable group. Such traumatic experiences include war or persecution, other life-threatening events, or family separation. In addition, refugees rarely have full access to the healthcare system in their host country, thereby substantially increasing an already elevated risk for several adverse health and social outcomes (Helgesson et al., 2021). Not only individual events experienced as intensely stressful can be triggers for mental health problems, but also poly-victimization experiences leading to cumulative effects (Finkelhor et al., 2011). Increased prevalence rates of mental disorders (e.g., depression, anxiety) and stress-related somatic complaints (e.g., pain) are, therefore, common in refugees. In particular, high rates of Post-Traumatic Stress Disorder (PTSD) have been observed in refugees, with an approximately 10-fold higher risk for PTSD among refugees compared to age-matched native populations (Fazel et al., 2005;Mölsä et al., 2014). Adverse outcomes are even more likely if there is a lack of social resources, particularly the case for young unaccompanied refugees (Jensen et al., 2014).In general, the mental and physical health of refugees is an important issue for health psychology research. Such research can expand our knowledge on the epidemiology of health-related problems and to better understand causes
