TST-R is a comprehensive method for treating traumatic stress in children and adolescents that adds to individually-based approaches by specifically addressing social environmental/system-of-care factors that are believed to be driving a child’s traumatic stress problems. TST-R is adapted for refugee youth and families who have experienced war and violence prior to resettlement and continue to face ongoing acculturation and resettlement stress. It consists of three components of prevention and intervention. TST-R has been adapted for, and implemented with, various refugee communities.
