This innovative collection extends the emerging field of stress biology to examine the effects of a substantial source of early-life stress: child abuse and neglect. Research findings across endocrinology, immunology, neuroscience, and genomics supply new insights into the psychological variables associated with adversity in children and its outcomes. These compelling interdisciplinary data add to a promising model of biological mechanisms involved in individual resilience amid chronic maltreatment and other trauma. At the same time, these results also open out distinctive new possibilities for serving vulnerable children and youth, focusing on preventing, intervening in, and potentially even reversing the effects of chronic early trauma. Included in the coverage: Biological embedding of child maltreatment Toward an adaptation-based approach to resilience                        Developmental traumatology: brain development and maltreated children with and without PTSD Childhood maltreatment and pediatric PTSD: abnormalities in threat neural circuitry An integrative temporal framework for psychological resilience The Biology of Early Life Stress is important reading for child maltreatment researchers; clinical psychologists; educators in counseling, psychology, trauma, and nursing; physicians; and state- and federal-level policymakers. Advocates, child and youth practitioners, and clinicians in general will find it a compelling resource.
