With It’s Not You, It’s What Happened to You: Complex Trauma and Treatment, Dr. Christine Courtois has simplified her extensive and, until now, quite scholarly work geared toward understanding and developing the concept of “complex trauma,” and the assessment and treatment thereof. Dr. Courtois provides here an abbreviated and easy-to-read explanation of what complex trauma is, how it develops, the ways in which it manifests, and how it can effectively be dealt with. The book opens with an explanation of trauma in general-providing historical perspective, examining the various types of traumatic experience, and looking in-depth at the chronic, repetitive, and layered forms of trauma that often build upon and reinforce one another to create complex trauma. Next Dr. Courtois discusses trauma-driven emotional turmoil, and trauma’s effects on memory, self-image, relationships, and even physical well-being. She then provides readers with a basic understanding of the ways in which complex trauma is diagnosed and assessed, with an explanation of all common trauma-related diagnoses-including stress disorders (such as PTSD), dissociative reactions and disorders, and frequently co-occurring issues (addictions, self-injury, sleep disorders, etc.) In the book’s final section, Dr. Courtois presents rudimentary information about the ways in which complex trauma and related issues can effectively be treated, including brief explanations of all therapeutic approaches and methods that might be used.
