Treatment of Complex Trauma: An Overview

Complex trauma is not just a clinical term—it reflects the deep and lasting impact of prolonged relational abuse, attachment disruptions, and other chronic traumatic experiences, often endured in circumstances of entrapment. The consequences are equally complex, extending far beyond the symptoms of classic PTSD to include disruptions across neurobiological, psychological, relational, somatic, and spiritual domains.
In this two-part webinar, internationally renowned trauma expert Dr Christine Courtois will draw on her decades of clinical and scholarly experience to guide participants through the evolving landscape of complex trauma treatment. Dr Courtois will begin by outlining the major aftereffects of complex trauma, with a focus on dissociation and neurobiology. She will also discuss the ICD’s freestanding diagnosis of Complex PTSD (CPTSD), comparing it to traditional PTSD and highlighting its implications for practice.
The webinar will examine recently developed Clinical Practice Guidelines for PTSD (from the APA, ISTSS, and U.S. Department of Defense/Veterans Affairs) and explore how their recommendations may—or may not—translate to work with complex trauma. Dr Courtois will then introduce newer Professional Practice Guidelines developed specifically for complex trauma and CPTSD by organizations such as the APA Division 56/ISSTD, and the UK CPTSD network. These guidelines are grounded in both empirical research and clinical wisdom, and reflect the preferences and lived experiences of trauma survivors themselves.
Drawing from the newly revised edition of her landmark 2009 book, Dr Courtois will present a comprehensive, integrative, and transtheoretical treatment model developed specifically for CPTSD and complex trauma.
Session 1 (Saturday, 11th October, 2025) will provide an updated conceptual framework for understanding complex trauma, including new typologies, a dimensional approach to diagnosis, and a developmental overview of trauma’s aftereffects across the lifespan.
Session 2 (15th November, 2025) will focus on practical application: assessment, treatment planning, patient engagement, progress tracking, and navigating the clinical challenges—and rewards—of supporting posttraumatic growth for both client and therapist.
