Unprecedented numbers of refugees are being displaced globally, with research revealing elevated prevalence rates of psychological distress among those affected. The aim of my research is to explore interactions between psychological effects of past trauma exposure and post-migration environmental stressors, to gain a better understanding of the threats posed to refugees’ mental health and wellbeing in daily life. To achieve this, I will identify and investigate key variables using a mixed methods approach, combining semi-structured interviews, thematic analysis, and real-time sampling of refugees’ dynamic responses to naturalistic environmental stressors using smartphone-based ecological momentary assessment.
