Task-shifting for refugee mental health and psychosocial support: A scoping review of services in humanitarian settings through the lens of RE-AIM.

There is a growing number of refugees forced to make homes in temporary camps or urban centers as they await resettlement, a process that can last decades. These refugees are at risk of serious mental health outcomes due to ongoing stress and trauma. One strategy commonly used in global mental health is the training of lay providers to deliver basic mental health and psychosocial programming to communities. While this tactic is currently being tested in refugee settings, there is limited evidence about the implementation of this strategy. The following scoping review aims to assess the implementation of task-shifting interventions within refugee settings, through the use of a robust implementation science framework.
