Adverse childhood experiences (ACEs) can negatively influence development. However, the lifelong effects of positive childhood experiences (PACEs) can mitigate the detrimental effects of  adverse ones. By integrating existing knowledge about (ACEs) with developmental research on preventing, buffering, and treating the effects of adversity, stress, and trauma on child development and subsequent health and functioning, this book identifies the most important of these (PACEs). It provides an interdisciplinary lens from which to view the multiple types of effects of enduring childhood experiences, and recommends evidence-based approaches for protecting children and repairing the enduring negative consequences of (ACEs) they face as adults. Students, researchers, clinicians, and health-care providers can use this research to understand the science of early life adversity, lifelong resilience, and related intervention and prevention programming to help those suffering from the lifelong effects of (ACEs). Chapters include many figures, graphs, diagrams, stories, and activities that aim to help readers apply the science to everyday life.
