Background: The vast majority of the world's refugees and people seeking asylum live in a state of sustained displacement. Little is known, however, about the mental health impact of prolonged insecurity. Objective: This study aimed to investigate the association between insecure visa status and mental health, suicidality, disability and social engagement in a sample of refugees and asylum-seekers living in Australia Method: Participants were 1,085 refugees with secure (i.e. permanent residency or Australian citizenship, n = 826, 76.1%) and insecure (i.e. asylum-seeker claim, bridging visa, temporary visa, n = 259, 23.9%) visa status who had arrived in Australia since January 2011, and were from Arabic, Farsi, Tamil or English-speaking backgrounds. Participants completed an online survey assessing pre-and post-migration experiences, mental health, disability and social engagement. Results: Results indicated that, after controlling for background factors, refugees with insecure visas had significantly greater PTSD symptoms, depression symptoms, thoughts of being better off dead and suicidal intent compared to those with secure visas. There were no group differences in disability. Refugees with insecure visas received support from significantly more groups in the Australian community than those with secure visas. Further, refugees with insecure visa status who had low group membership showed greater depression symptoms and suicidal intent than those with secure visa status who had low group membership. Conclusion: Findings highlight the negative mental health consequences of living in a state of protracted uncertainty for refugees and people seeking asylum, and the key role of social engagement in influencing mental health amongst insecure visa holders. Results also underscore the importance of designing and implementing policies and services that facilitate improved mental health for those with visa insecurity. La asociación entre la inseguridad de la visa y la salud mental, la discapacidad y la participación social en los refugiados que viven en Australia Antecedentes: la mayoría de los refugiados del mundo y las personas que solicitan asilo viven en un estado de desplazamiento sostenido. Sin embargo, se conoce muy poco sobre el impacto en la salud mental de la inseguridad prolongada. Objetivo: este estudio investiga la asociación entre el estatus inseguro de la visa y la salud mental, la suicidalidad, la discapacidad y la participación social en una gran muestra de refugiados y solicitantes de asilo que viven en Australia. Metodología: Los participantes fueron 1.085 refugiados. Un grupo tenía un estatus seguro de la visa (como por ejemplo residencia permanente o ciudadanía australiana n=826, 76.1%) y otro grupo tenía un estatus inseguro de su visa (como por ejemplo solicitantes de asilo, visa puente 1 , visas temporales, n = 259, 23,9%). Los sujetos llegaron a Australia desde Enero de 2011, y eran de origen árabe, farsi, tamil o angloparlante. Los participantes completaron un cuestionario online que evaluaba las...
