This book contributes to a better understanding of what makes people and communities resilient in the face of disasters, violence and terrorism. This resilience is understood as a resource that facilitates recovery, effective functioning and positive outcomes in the wake of major critical events that threaten the well-being of individuals, families, communities and nations. The chapters in this publication present complementary perspectives on resilience in a variety of socially adverse settings and how to assess resilience beyond the level of an individual. The contributing authors not only consider evidence of resilience in the aftermath of mass trauma, but uniquely explore it from a developmental perspective and expand the focus from individual resilience to the broader ecological levels of community and society. The book contains 11 chapters reflecting different aspects of resilience. Presentation of these different perspectives will be helpful to scholars and students of human behavior affected by life-threatening crises. Together, the chapters present up-to-date research that affirms human strength when confronted by the extreme experiences. The book also covers the broad landscape of current knowledge and research topics on resilience that are related to mass violence and terrorism, which is one of the growing concerns of the world today.
