Social change is omnipresent, rapid, and influential, as it entails people’s responsive adaptation. Both social change and psychosocial responses to it have been constantly attracting attention, research, deliberation, theorizing, and policy reengineering, thus furthering social change. Social change can cover economic, political, cultural, and communal aspects. It can deal with issues such as the economic or financial crisis, marketization, revolution, social movement, globalization, nation building, migration, urbanization, demographic transition, secularization, acculturation, enculturation, modernization, posmodernization, military or business war, and so on. Psychosocial responses can cover morale, demoralization, distress, anger, cooperation, alliance, trust, aggression, suicide, caring, help seeking, social integration, social cohesion, social identity, rebellion, and crime. This book presents a thorough understanding of social change and psychosocial responses to it which is indispensable to the journey toward a better society and life.
