For the past six years, children in Syria have been bombed and starved. They have seen their friends and families die before their eyes or buried under the rubble of their homes. They have watched their schools and hospitals destroyed, been denied food, medicine and vital aid, and been torn apart from their families and friends as they flee the fighting. Every year that the war goes on plumbs new,  previously unimaginable depths of violence against children, and violations of international law by all sides.

Abstract
Objectives
Given the recent peak in refugee numbers and refugees’ high odds of developing post-traumatic stress disorder (PTSD), finding ways to alleviate PTSD in refugees is of vital importance. However, there are major differences in PTSD treatment response between refugees, the determinants of which are largely unknown. This study aimed at improving PTSD treatment for adult refugees by identifying PTSD treatment response predictors.
Design

The first studies on migration and mental health focused primarily on immigration in the Unites States in the beginning of the 20th century. Higher levels of mental health problems or “insanity” were observed among migrants as compared to host populations. Selective migration of mentally ill people was understood to explain this difference. Although hypomanic traits such as impulsiveness, extraversion and risk seeking behaviour may seem to predispose individuals to emigrate, the so-called selective migration hypothesis has never been empirically supported.

Background: A significant proportion of trauma survivors experience an additional critical life event in the aftermath. These renewed experiences of traumatic and stressful life events may lead to an increase in trauma-related mental health symptoms.
