Understanding Complex PTSD
Complex Post-Traumatic Stress Disorder (C-PTSD) is a condition that develops in response to repeated, prolonged, or chronic trauma – particularly trauma that involves interpersonal violation and from which escape was difficult or impossible. It is distinct from standard PTSD in important ways: beyond the core PTSD symptoms of intrusion, avoidance, and hyperarousal, C-PTSD involves profound disturbances in self-organization – negative self-concept, difficulties with emotional regulation, and disturbances in relationships and consciousness. C-PTSD is recognized in ICD-11 (the WHO’s diagnostic manual) and is increasingly recognized in clinical practice, though it remains underdiagnosed. Common sources include childhood abuse and neglect, domestic violence, human trafficking, prisoner of war experiences, and any situation involving repeated trauma without adequate support or means of escape. Treatment for C-PTSD requires a specialized, phased approach that differs significantly from standard PTSD treatment – and rushing to trauma processing without adequate stabilization can worsen rather than improve the condition.

About Complex PTSD Therapy
Why seek therapy?
Adults seek therapy for C-PTSD when the pervasive impact of chronic trauma on their sense of self, their relationships, and their daily functioning has become undeniable – often following a breakdown of previously effective coping strategies, a relationship crisis, or simply a growing recognition that the strategies they have used to survive are no longer sufficient for living well. Many have received multiple diagnoses over the years – depression, anxiety, borderline personality disorder, bipolar disorder – without any of them fully capturing or addressing what is actually happening.
How therapy helps
Therapy for C-PTSD follows the Phase-Based Treatment model developed specifically for complex trauma. Phase 1 focuses on safety, stabilization, and skills development – building the emotional regulation, distress tolerance, and grounding skills needed before trauma processing can be approached safely. Phase 2 addresses the traumatic memories and experiences using evidence-based trauma processing approaches adapted for complex presentations. Phase 3 focuses on integration and reconnection – developing a coherent sense of self, improving relationships, and building a life oriented toward the future rather than organized around the past.
Benefits of Complex PTSD Therapy
Specialized Phase-Based Treatment
C-PTSD requires a specialized, phased approach that differs fundamentally from standard therapy or even standard PTSD treatment. Our therapists are trained specifically in complex trauma and apply evidence-based phased treatment that prioritizes safety before processing.
Addressing the Full Complexity
C-PTSD affects not just traumatic memory but identity, emotional regulation, relationships, and the fundamental sense of safety in the world. Effective treatment addresses all of these dimensions – not just the trauma symptoms in isolation.
A Corrective Relational Experience
For many people with C-PTSD, the trauma was relational – occurring within relationships that should have been safe. The therapeutic relationship itself is a central healing mechanism – a consistent, boundaried, genuinely caring relationship that begins to revise the fundamental expectations about relationships formed in trauma.
C-PTSD is complex. So is the treatment. Our therapists are trained for exactly this.

Our Approach to Complex PTSD Therapy
C-PTSD therapy at Empire follows the Phase-Based Treatment model as developed by Judith Herman and refined by the International Society for Traumatic Stress Studies (ISTSS). Phase 1 – safety and stabilization – is never abbreviated, because adequate stabilization is the foundation on which all subsequent work rests.
Stabilization work builds emotional regulation skills, distress tolerance, grounding techniques, and internal resources. This phase may last months for clients with the most complex presentations – and it is not wasted time; the skills developed here make the subsequent work possible.
Trauma processing in Phase 2 uses EMDR, trauma-focused approaches adapted for complex presentations, and in some cases somatic and Internal Family Systems approaches – tailored to the individual’s specific history, needs, and response to treatment.
Phase 3 addresses integration and reconnection: developing a coherent, compassionate self-narrative, improving the capacity for intimate relationships, and building a life that is oriented toward the future. This is not the end of therapy but the beginning of living.

Common Questions About Complex PTSD Therapy
How is C-PTSD different from PTSD?
Standard PTSD typically develops from a discrete traumatic event or events. C-PTSD develops from repeated, prolonged trauma – particularly interpersonal trauma from which escape was difficult. In addition to PTSD symptoms, C-PTSD involves profound disturbances in self-concept, emotional regulation, and relationships that require additional therapeutic attention.
I have been diagnosed with borderline personality disorder. Could it actually be C-PTSD?
The overlap between BPD and C-PTSD is significant, and many people who have been diagnosed with BPD have trauma histories that would meet criteria for C-PTSD. The diagnostic distinction matters therapeutically – C-PTSD is treated with phased trauma treatment, while BPD is treated primarily with DBT. A thorough assessment can help clarify the most accurate and clinically useful formulation.
How long does C-PTSD treatment take?
C-PTSD treatment is typically longer than standard therapy – often extending over one to three years or more for complex presentations. Stabilization alone can take many months. The investment reflects the depth and pervasiveness of the impact of chronic trauma, and the time needed to address it safely and thoroughly.
Is a referral required?

History of Complex PTSD Treatment
Evolution of Treatment
The concept of Complex PTSD was first proposed by Judith Herman in her landmark 1992 work ‘Trauma and Recovery,’ which argued that the existing PTSD diagnosis inadequately captured the presentations seen in survivors of prolonged interpersonal trauma. The Phase-Based Treatment model she developed has become the foundation of complex trauma treatment globally. C-PTSD was formally recognized in ICD-11 in 2018, providing diagnostic validation for what clinicians had been observing and treating for decades.
A Modern Approach in Canada
Current best practice in Canada uses phased, trauma-focused treatment for C-PTSD – following the ISTSS guidelines that prioritize stabilization before processing. EMDR, somatic approaches, IFS, and schema therapy are among the primary evidence-based approaches adapted for complex presentations. The field increasingly attends to the relational dimensions of both the trauma and the healing process.
Complex trauma requires complex, specialized care. That is exactly what we provide.
