The aim of this scoping review is to quantitatively examine the impact of war-related experiences on children's mental health outcomes. This master's thesis addresses the following two research questions: What proportion of children reported experiencing war-related events and to what extent did exposure to war-related experiences impact children’s mental health outcomes. Fifteen (15) studies were used for this review, which had been published the last 5 years, and 4 of which were referring to the war in Palestine, 2 studies were about Syrian refugees in Lebanon and 2 about refugees in Turkey. The rest of the studies were about Syrian refugees in Greece, Jordan, displaced children in the Middle East, armed conflicts in Colombia, Tanzania, Sierra Leone and Ukrainian students in Poland. The results revealed that almost all children had been exposed to different traumatic war-related events, meanwhile this exposure had affected their mental health, since serious mental health problems, such as post-traumatic stress disorder (PTSD), depression, anxiety and externalizing problems, existed.
