Post-migration journey: Asylum, trauma and resilience, different trajectories - A comparison of the mental health and post-migration living difficulties of documented and undocumented migrants in Belgium.

Abstract

Research on the impact of post-migration experiences on the mental health of migrant populations has shown a predictive link between post-migration living difficulties and psychological distress. While many studies have focussed on refugees and asylum seekers, there is a considerable gap in the literature concerning undocumented migrants. The aim of this study was to assess the differences in mental health between documented and undocumented migrants in Belgium. It identified the post-migration difficulties encountered by these two groups and measured their impact on their levels of trauma, resilience, anxiety, depression and their assumptive world. This study involved 69 participants, aged 18 to 68 years, who were either documented or undocumented resident in Belgium. Our data collection included the Post-Migration Living Difficulties Checklist for the measurement of post-migration difficulties, the Posttraumatic Stress Disorder Checklist - DSM-V version for the measurement of trauma, the World Assumptions Questionnaire for the measurement of the assumptive world, the Hopkins Symptom Checklist-25 for the measurement of depressive and anxiety disorders and the Adult Resilience Measure - Revised for the measurement of resilience. Our analyses showed that the mental health of undocumented migrants was poorer than that of documented migrants, with higher levels of trauma, anxiety and depression, a more negative assumptive world, a lower sense of control and lower total and personal resilience. Our results also revealed that post-migration living difficulties were more severe and more numerous for undocumented migrants, and that they were associated to different themes in both groups. The fact that post-migration experience plays such an important role in the mental health of migrant populations raises significant clinical, political and societal considerations. Furthermore, it would appear that undocumented migrants represent a distinct migratory group with their own specificities in terms of migration journey and mental health.
