This thesis explores how the Hungarian service delivery practitioners construct the vulnerability narratives of their asylum seeker and refugee clients and how they reflect on the implications of their intervention. For the method of inquiry, the study employs qualitative thematic analysis in order to identify reoccurring themes and patterns within the material written by professionals, paraprofessionals, and volunteers. When applying the concept of vulnerability and reflexivity in service delivery practice, the analysis suggests that the consequences of war, conflict, fear of persecution, and the hostile environment in Hungary further perpetuate clients' vulnerability. Furthermore, mental health issues, the lack of access to education, the unemployment problems resulting in financial hardship, and housing difficulties are all impacting the vulnerability experiences and coping mechanisms. Also, the material suggests that besides the objective categorizations of vulnerability, there are also its subjective perceptions that emerge in the narratives through the reflections of service delivery practitioners, expanding the concept of vulnerability.
