Political violence has disrupted the lives of millions of children around the world. Responding to the gravity and scale of this phenomenon, this volume is intended to stimulate discussion and research on children’s exposure to political violence and its psycho-social effects. It brings together for the first time in a single volume three areas of scientific activity in different disciplines: research on effects, programs for intervention, and laws and policy for prevention of political violence to children. Section I presents reviews of research on children exposed to political violence, including child soldiers and refugee children, as well as an examination of methodology and ethics. Section II contains research on interventions with children exposed to political violence, including individual therapy and school, family, and community interventions. Section III covers legal and social issues in deterring the recruitment of children to violent causes and protecting children in armed conflict. Pulling together the work of leading scholars and practitioners in the social sciences and international law, this volume argues that the prevention of political violence to children is possible, and it provides a crucial basis for ideas for prevention.
