The aim of this chapter is to highlight the impact of trauma and intervention with Palestinian children. A reanalysis of secondary data of previous work in the field using the words trauma, Palestinians, intervention, PTSD, anxiety, depression, Gaza Strip, and West Bank was entered in web-based research databases including Medline, PsycINFO, and Scholar Portal. The severity of traumatic events is changing and the types of traumatic experiences now include seeing mutilated bodies on TV, hearing and seeing shelling, exposure to sonic bombs, and witnessing home bombardment and demolition. PTSD prevalence ranged in children from 10 percent to 71 percent while the rate of PTSD in the West Bank ranged from 35 percent to 36 percent. The rate of anxiety ranged from 28.5 percent to 33.9 percent, and depression ranged from 40 percent in children of Gaza and the West Bank to 50.6 percent. The general mental health of children rated by parents and teachers was 20.9 percent and 31.8 percent. Studies showed risk factors that interfered with well-being such as being a boy, living in a large family, low socioeconomic status of the family, exposure to domestic and political violence, and being an orphaned child. Other risk factors included children in the labor force, with physical problems, and living near the border areas. Intervention studies had equivocal results when using psychodrama, school mediation, writing for recovery, and teaching children recovery techniques. This review showed that Palestinian children’s exposure to war and conflict leads to negative outcomes including mental health problems that triggered the start of community intervention programs. These programs did not change the negative impact of trauma, which highlights the need to find other ways to protect children in Palestine and help them cope with their daily life adversities and war.
