Combining scientific and clinical perspectives, this volume brings together leading authorities on complex traumatic stress and its treatment in adults. Contributors review the research that supports the conceptualization of complex traumatic stress as distinct from PTSD. They explore the pathways by which chronic trauma can affect psychological development, attachment security, and adult relationships. Chapters describe evidence-based assessment tools and an array of treatment models for individuals, couples, families, and groups.
See also Drs. Courtois and Ford's authored book, Treatment of Complex Trauma, which presents their own therapeutic approach for adult clients in depth, and their edited volume Treating Complex Traumatic Stress Disorders in Children and Adolescents.
If you want to understand C-PTSD, this is the book for you. It explains clearly what is it(from both a psychological and biological point of view), its treatment (with a focus on the therapeutic alliance), and other related topics (such as the usefulness of the diagnosis and how to assess it).
I made a free presentation as a summary for the book that you can watch here
Why not 5 stars? Because it's a collection of chapters written by different authors, there is a lot of repetition, that I would have edited heavily.
