ABSTRACT People detained in immigration detention facilities are directly and intentionally excluded from participating in occupations within society and experience negative health consequences. This study used interpretative phenomenological analysis to illuminate the experiences and meaning of occupation within this restrictive physical and social environment. Semi-structured interviews were conducted with four men who were previously detained. Three group experiential themes arose from the transcripts: 1) Occupational context of detention: Confusion, uncertainty, incarceration; 2) Doing is a fight with your mind; and 3) Resisting to survive, surviving to resist. All participants experienced occupational deprivation; but, at times, participants connected positive meanings such as hope, resistance, and collective action to their occupational experiences. Alongside the occupational deprivation inherent to immigration detention there are possibilities for experiencing purposeful occupation imbued with positive meanings. The study illuminates the possibilities of more socially transformative occupational experiences, despite contextual constraints and limited opportunities.
