Background: Upon arrival in the host country, refugees and asylum seekers (RAS) experience a range of post-migration living difficulties (PMLD), which are often linked to psychological symptoms such as post-traumatic stress (PTS). Initial research suggests that attachment insecurity partly explains the association between PMLD and psychological symptoms in RAS. However, the mechanisms through which attachment insecurity may act as a mediator are not well understood, though emotion dysregulation is one of the potential candidates.
