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.
