Objective:
Children in asylum-seeking families are increasingly subject to deterrent host nation policies that undermine security in the post-migration context, however, little is known on the mental health consequences of such policy. This study examined the impact of prolonged visa insecurity on child mental health, by comparing two cohorts of refugee children entering Australia between 2010 and 2013, distinguished by visa security.
Methods:
The insecure visa sample comprised children from Tamil asylum-seeking families, while the secure visa sample was drawn from refugee families participating in the multi-ethnic 'Building a New Life in Australia' cohort study. Children in each sample were assessed for current mental health problems and trauma exposure. Mothers were assessed for trauma exposure, post-migration family stressors and post-traumatic stress disorder (PTSD). The effects of prolonged visa insecurity on child mental health via family-and child-level variables were modelled using multi-level path analysis.
Results:
Data comprised 361 children, aged 10-18, and 242 mothers across three levels of visa insecurity: permanent protection (n = 293), temporary protection (n = 40) and bridging visa (n = 28). Modelling showed that (1) visa insecurity was associated with poorer child mental health, (2) the association was mediated sequentially by post-migration family stressors and maternal PTSD and (3) the association was moderated by maternal PTSD.
Conclusion:
Our findings suggest that when government policy persistently undermines post-migration security, the capacity of families to protect children from accrued stressors is lowered, leaving a significantly higher proportion of children developing along trajectories of risk rather than resilience.
