Over 1 billion persons worldwide are affected by the psychological and physical impact of violence and natural disaster. In many societies today, torture and other forms of cruel and degrading abuse still exist. Domestic violence remains a scourge of our planet. The world's leading experts in medicine, psychiatry, humanitarian efforts, medical anthropology, human rights, economic development and research and evaluation have worked together to create this first ever scientific and culturally sensitive health/mental health textbook. The textbook has been produced in a digital format (and a paperback edition as well) so that it can be readily used in the field and clinics in the developing world, in refugee camps and other resource poor environments. An interdisciplinary and innovative Global Mental Health Action Plan is united with best practices in a usable and effective approach for the care of traumatized communities worldwide.
