Complex PTSD — Definitions, Differentiation from PTSD, and Integrative Treatment

This continuing professional development course offers psychologists and psychotherapists a comprehensive, evidence-based understanding of Complex Post-Traumatic Stress Disorder (Complex PTSD / CPTSD), the diagnostic category officially recognized by the ICD-11 in 2018. Across eight structured modules, you will learn to distinguish CPTSD from classical PTSD, identify the six ICD-11 diagnostic criteria including the Disturbances in Self-Organization (DSO) triad — affective dysregulation, negative self-concept, and interpersonal difficulties — and conduct rigorous psychometric assessment using internationally validated instruments (ITQ, CAPS-5, PCL-5, DES-II, ACE).

The course explores the consensus three-phase treatment model formalized by Judith Herman and Marylène Cloitre — stabilization, trauma processing, reconnection — and provides clinicians with the integrative framework recommended by the ISTSS for treating survivors of prolonged, interpersonal, and inescapable trauma. You will gain practical mastery of complementary therapeutic approaches: psychodynamic contributions (Winnicott's holding function, traumatic transference, mentalization following Fonagy and Bateman, disorganized attachment), and cognitive-behavioral contributions (Cloitre's STAIR program, Resick's Cognitive Processing Therapy, Ehlers and Clark's cognitive model, DBT-informed competencies).

The final module addresses the clinician's own well-being, including vicarious trauma, compassion fatigue, supervision as ethical requirement, and concrete self-care practices. Designed for sustainable, durable, and clinically grounded practice with one of the most demanding patient populations in contemporary clinical psychology.

Learning Objectives

Upon completion of this course, participants will be able to:

1. Distinguish Complex PTSD from classical PTSD by applying the six ICD-11 diagnostic criteria, including the DSO triad (affective dysregulation, negative self-concept, interpersonal difficulties), and conducting differential diagnosis with borderline personality disorder, dissociative disorders, and Developmental Trauma Disorder.
2. Conduct a rigorous and clinically safe psychometric evaluation using validated instruments (International Trauma Questionnaire, CAPS-5, PCL-5, DES-II, ACE) while leading a containing initial interview that prevents decompensation and identifies contraindications to early exposure.
3. Structure treatment according to the international consensus phasic model (stabilization, trauma processing, reconnection), recognizing the clinical indicators for transition between phases and integrating psychodynamic and cognitive-behavioral approaches within a single coherent framework.
4. Implement sustainable clinical practice by recognizing the manifestations of vicarious trauma and compassion fatigue, mobilizing supervision as an ethical requirement, and applying concrete self-care practices that support long-term professional engagement with complex trauma populations.
