“ Complex trauma requires complex treatment — a phased, sequenced approach that prioritises safety before any processing of traumatic material.”
Christine Courtois (Treatment of Complex Trauma, 2016)
Complex trauma presents counsellors with a distinct set of clinical challenges — ones that standard counselling approaches are often not designed to address. Australia’s Blue Knot Foundation, the National Centre of Excellence for Complex Trauma, has developed practice guidelines that outline what effective, evidence-informed practice in this area can be.
What is Complex Trauma?
Complex trauma occurs from repeated, prolonged, or chronic traumatic experiences, often occurring in the context of close relationships. Common examples include childhood abuse or neglect, domestic violence, prolonged medical trauma, and experiences of systemic or racial trauma.
Unlike single-incident trauma, complex trauma can often occur during formative developmental stages, affecting not just a person’s response to a specific event, but their fundamental sense of self, their capacity to regulate emotions, and their ability to trust others — including the counsellor. As Blue Knot’s Practice Guidelines for Clinical Treatment of Complex Trauma (2019) note, clients with complex trauma histories do not start from the same place as those who have experienced a single traumatic event: they typically come without a prior foundation of safety and wellbeing to draw upon.
Key Differences When Working with Complex Trauma
- The Therapeutic Relationship Takes Priority
In single-incident trauma work, evidence-based interventions such as EMDR or trauma-focused CBT can often be introduced relatively early. With complex trauma, the therapeutic relationship itself is the primary vehicle for change. Blue Knot’s guidelines emphasise that because complex trauma is almost always interpersonal in origin, relational repair is central to treatment. Clients who have experienced relational trauma may find trust difficult to establish and easy to rupture. Building a safe, consistent, and boundaried therapeutic relationship must come before any trauma processing work begins.
Blue Knot also cautions counsellors to reappraise standard counselling principles — such as unconditional positive regard, strengths-based orientation, and the ‘client as expert’ framework — in the context of complex trauma. While valuable, these approaches require careful adaptation rather than automatic application.
- Stabilisation Before Processing
A phased approach is essential. Blue Knot’s clinical guidelines recommend that therapy for complex trauma follow a sequenced, three-phase model: safety and stabilisation, trauma processing, and integration. Counsellors will spend considerably more time in the stabilisation phase — building the client’s window of tolerance, developing emotion regulation skills, and establishing internal and external safety — before any direct trauma processing is appropriate.
Importantly, Blue Knot’s guidelines note that many complex trauma clients have longstanding self-regulatory impacts. This means that stabilisation is not simply about accessing inner resources but actively developing them — a significant departure from standard counselling assumptions that clients already have the internal capacity to heal.
- Dissociation and Fragmented Memory
Clients with complex trauma histories often present with dissociative symptoms and fragmented or incomplete memories. Blue Knot’s guidelines — including our dedicated publication on Identifying and Treating Complex Trauma-related Dissociation — highlight that counsellors need to recognise signs of dissociation during sessions, know how to work gently with them, and avoid approaches that push clients beyond their window of tolerance.
Psychoeducation about dissociation is identified as a valuable tool for normalising these experiences. The guidelines also caution against targeting surface symptoms without understanding their underlying traumatic origin — a common risk when using short-term interventions with complex trauma clients.
- Identity, Shame, and Self-Concept
Complex trauma — particularly when experienced in childhood — often results in deep-seated shame and a distorted sense of self. Clients may present with core beliefs such as ‘I am bad’ or ‘I deserved what happened.’ Blue Knot’s guidelines frame these not as cognitive distortions to be challenged, but as survival adaptations that require careful, respectful exploration.
The guidelines emphasise a holistic treatment orientation that addresses identity development, self-management, and relational capacity — moving beyond symptom reduction toward supporting clients to build a coherent, meaningful sense of self.
“When you push patients to process trauma too soon, their symptoms get worse or they drop out of treatment.”

Implications for Practice
Counsellors working with complex trauma benefit from:
- Specialist training in trauma-informed and trauma-specific approaches, aligned with Blue Knot’s practice guidelines
- Regular clinical supervision with a trauma-informed supervisor — Blue Knot has published specific guidelines for clinical supervisors of therapists working with complex trauma
- Familiarity with somatic and body-based approaches, which can be particularly effective where verbal processing is limited
- Strong self-care practices and ongoing monitoring of vicarious trauma, given the cumulative weight of this work
Blue Knot’s guidelines also include a self-assessment tool for clinicians to evaluate their readiness for complex trauma work. Where counsellors are not equipped to work in this area, ethical practice includes timely referral to clinicians with the requisite skills.
Complex trauma work is some of the most meaningful — and most demanding — in the counselling field. Grounding your practice in evidence-based guidelines, such as those developed by Blue Knot Foundation, is an important foundation for providing effective, safe, and ethical care.
