Book excerpt: This book examines the modern pandemic of online child sexual exploitation (OCSE). It explores the prevalence, perpetration, impact, and victimization of as well as therapy for child sexual exploitation and its interaction with child sexual abuse. Chapters discuss OCSE from neuropsychological, epidemiological, neurological, behavioral, psychological, clinical, neurobiological and epigenetic perspectives. The volume also addresses the physical and mental impact of early exposure to pornography. The book serves as a resource on an issue that is proving exponentially complex as technology ceaselessly evolves at a faster rate than its consequences can be understood and addressed. Key areas of coverage include: Neuropsychological changes and dysfunctional coping mechanisms resulting from both online and offline child sexual abuse. The psychological, emotional, and physical impacts (e.g., depression, anxiety, PTSD, and self-harm) of child sexual abuse. Prevention and early intervention strategies, including scalable technological responses. Developing a public health approach to preventing and addressing online child abuse and exploitation. Porn culture and its impact on children, adolescents, and emerging adults. The neurobiology and epigenetic impact of trauma. This book is a must-have resource for researchers, clinicians, and graduate students in child and school psychology, public health, social work as well as interrelated disciplines, including neuropsychology, neurobiology, sociology, anthropology, and educational policy and politics.
