This book explores the growing understanding and evidence base for the role of trauma in sexual offending. It represents a paradigm shift, in which trauma is becoming an important risk factor to be considered in the treatment of individuals convicted of sexual crime. The authors consider the theoretical and historical explanations and understandings of sexual offending and its relationship with early trauma, paving the way for a volume which considers client's treatment needs through a new, trauma-informed lens. The experiences and challenges of specific groups are also explored, including young people and women. Readable, yet firmly anchored in a sound evidence base, this book is relevant to psychologists, therapists, criminologists, psychiatrists, mental health nurses, social workers, students, and to practitioners and the general public with an interest in learning more about the topic.
