"The conflict between the will to deny horrible events and the will to proclaim them aloud is the central dialectic of psychological trauma."
In 1992, psychiatrist Judith Herman noticed something the diagnostic manuals were missing. The picture of PTSD they described was built around single, terrible events: a car crash, a combat firefight. It didn't capture what she was seeing in survivors of prolonged, repeated harm. The children raised in chronic fear. The people held in violent relationships for years. The survivors of captivity, trafficking, and political terror. Their injury was deeper and more total. It wasn't just that something terrible had happened. It was that it kept happening, and they couldn't get out.
Herman called this Complex PTSD. Her insight was that trauma under conditions of captivity, whether the bars are literal or relational, doesn't just produce flashbacks and hypervigilance. It reshapes the foundations of a person: their sense of who they are, their ability to trust and stay close to others, their capacity to regulate emotion, and their basic belief about whether the world can ever be safe. The damage isn't only to memory. It's to identity.
Single-incident trauma asks: "What happened to me?" Complex trauma asks a harder question: "What did living through that, over and over, make me become?"
The defining condition isn't the severity of any one event. It's entrapment: repeated harm in a situation you couldn't escape, couldn't fight, and couldn't stop. And it doesn't always look dramatic from the outside. Sometimes the harm is what was absent: years of never being seen, soothed, protected, or kept safe. The nervous system registers chronic neglect as danger too. It just keeps score.
Herman, J. L. (1992). Trauma and Recovery. Basic Books.
For three decades, this was a clinical concept without an official home. That changed in 2022, when the World Health Organization formally recognized Complex PTSD (6B41) as a distinct diagnosis in the ICD-11, the global diagnostic standard. North America's DSM-5 still does not list it separately, which is part of why so many survivors get routed instead into diagnoses like depression, anxiety, ADHD, bipolar disorder, or "treatment-resistant" labels that miss the root. (I unpack that gap on DSM vs ICD and When Trauma Is Misdiagnosed.)
And I'll be straight with you about why this page exists: I didn't meet complex PTSD in a textbook. I lived inside these six domains for years before I ever heard them named, collecting other people's labels for what was supposedly wrong with me. When I finally found this framework, my whole history started making sense in reverse. This page is me handing you, in one afternoon, what took me years to dig out. (Who I am and why I built this: About Me and Why This Site Exists.)
The thing to hold onto:
You are not broken.
You adapted to something that should never have happened.
Complex PTSD isn't tied to one kind of person or one kind of story. The common thread is always the same shape: harm that was repeated, prolonged, and hard or impossible to escape, often during childhood or at the hands of someone you depended on. If any of these feel familiar, you are not on the outside of this conversation. You may be at the centre of it.
Ongoing physical, sexual, or emotional abuse, or the chronic absence of safety, attunement, and care during the years your brain was still forming.
A home shaped by a caregiver's addiction, untreated mental illness, violence, or unpredictability. Where you learned to read a room before you could read a book.
Months or years inside a relationship defined by coercion, fear, and control, where leaving felt dangerous or impossible.
Trafficking, kidnapping, hostage situations, imprisonment, or high-control groups and cults that isolate and dominate.
Refugees, survivors of genocide or political terror, and those who lived through prolonged conflict or systemic oppression.
Repeated frightening medical procedures, chronic illness, or being a child forced into caretaking and adult responsibility too young.
You don't need a single "big" event to belong here, and you don't need to have had it "worse" than someone else. Complex trauma is measured by duration, repetition, and entrapment, not by how dramatic it would look to a stranger. Quiet, ongoing, invisible harm counts. And here's the cruel trick: when it's all you've ever known, the bad becomes normal and the normal becomes strange. You can't see the water you grew up drowning in, and that's how people carry this for decades without a name for it. (See also ACEs & Risk and Toxic Stress.)
The ICD-11 describes Complex PTSD across six domains, grouped into two halves. The first three are the core of PTSD itself. The next three, known clinically as "disturbances in self-organization", are the deeper marks that prolonged trauma leaves on identity, emotion, and connection. Together they form a fuller portrait of what surviving the unsurvivable does to a person.
The past intruding on the present: nightmares, flashbacks, or sudden vivid memories that feel like the danger is happening again right now, not just being remembered.
PTSD coreSteering away from anything that brings the experience back: certain thoughts and feelings, or the people, places, and situations that act as reminders.
PTSD coreA nervous system stuck on high alert: hypervigilance, feeling constantly on guard, jumpy, or easily startled, as if the emergency never ended.
PTSD coreEmotions that swing too hard or shut down entirely: taking a long time to calm after being upset, or feeling numb and emotionally flat.
Self-organizationA persistent sense of being worthless, a failure, or fundamentally bad: beliefs about yourself that the trauma wrote in, not ones you arrived with.
Self-organizationFeeling distant or cut off from others, and finding it hard to feel close or stay emotionally connected, even with people you love.
Self-organizationAll six domains here belong to the ICD-11, the World Health Organization's diagnostic system and the only major framework that recognizes Complex PTSD as its own distinct diagnosis. It keeps PTSD lean (the first three domains) and adds three separate "self-organization" domains to define C-PTSD.
North America's DSM-5 took a different road. In 2013 it expanded its single PTSD diagnosis from three symptom clusters to four, adding a cluster called "negative alterations in cognitions and mood", but it pointedly did not create a separate Complex PTSD diagnosis. Because of that divergence, the DSM's model doesn't map cleanly onto the six domains on this page; everything here follows the ICD-11. (I unpack the two systems on DSM vs ICD.)
The reflection below is organized around these same six domains, so whatever it shows you maps directly onto this picture.
This is a reflection, not a test, and not a diagnosis. It is adapted for education from the International Trauma Questionnaire (ITQ), the measure clinicians use to explore the six domains of Complex PTSD. Only a qualified professional can diagnose anything, and this tool is not a substitute for that conversation.
The point here is simply to help you see the shape of your own experience across the six domains. To make the invisible a little more visible. Nothing you enter is saved, sent, or tracked. It stays in your browser and disappears when you close the page.
As you answer, hold in mind a distressing or traumatic experience, or a period of your life when you didn't feel safe. There are no right answers. Go gently. If it starts to feel like too much, it's completely okay to stop.
The full International Trauma Questionnaire (ITQ), including the formal scoring guide and translations in many languages, is freely available in the public domain from its authors at the International Trauma Consortium. A printable, authoritative copy you can keep or bring to a clinician.
Your map will appear here once you complete the reflection above.
This isn't a score, and it isn't a verdict. It's a landscape: a picture of how strongly each of the six domains shows up for you right now. Every domain matters, whether it's lit up or quiet.
Self-directed work is real work, but it has a ceiling, and hitting that ceiling is not failure. If your map is loud, or you're just tired of carrying this alone, two pages on this site were built for exactly that moment: the correct intake doors for Recovery Alberta & AHS (the public system, and how to actually get through it) and how to find a trauma therapist in Alberta (a survivor's guide, including what to ask for and when to walk away).
Adapted for educational reflection from Cloitre, M., Shevlin, M., Brewin, C. R., Bisson, J. I., Roberts, N. P., Maercker, A., Karatzias, T., & Hyland, P. (2018). The International Trauma Questionnaire (ITQ). The ITQ is freely available in the public domain; the official version can be downloaded from the International Trauma Consortium. This adaptation simplifies the instrument for self-understanding and is not a validated administration, a score, or a diagnosis.
Here is something that trips up almost everyone who reads about Complex PTSD: the formal diagnosis is built on thresholds. To meet it, certain domains have to "count" in a particular pattern. And so it's common for someone to recognize themselves powerfully in five of the six domains, and then, because the sixth doesn't reach the cutoff, conclude that the whole thing must not apply to them. That the door is closed. That their pain doesn't qualify.
Falling one short of a diagnostic threshold changes a checkbox. It changes nothing about your actual experience.
That's exactly why the reflection above shows you a landscape instead of a pass/fail. If five domains are lit up and one is quiet, the honest takeaway isn't "this doesn't apply." It's "there is real, meaningful work available to me across these areas, right now." The dimensional view exists precisely to pull you out of the trap of waiting for a label before you let yourself begin.
And there's a deeper reason not to chase the label as if it were the prize. In Alberta, the healing approaches for PTSD and Complex PTSD are largely one and the same. Nervous-system regulation, trauma-focused therapy, safe relationships, somatic work, building distress tolerance. These don't require a particular diagnostic code to be useful to you. The body that learned to brace heals the same way whether or not a chart says "6B41."
One more honest thing, because it belongs on this page: if you've been numbing all of this with alcohol, drugs, food, work, or anything else that kept the volume down, that is not a separate problem from what you just read. It's usually the same injury wearing a different coat. You weren't chasing a high. You were chasing the absence of pain. (I take that overlap apart in When Trauma and Addiction Overlap and When Sobriety Feels Worse.)
None of this is to dismiss diagnosis entirely. A formal diagnosis can matter for real-world reasons. It can make it easier to take protected time off work, access certain funded programs, or get accommodations. Those things are worth pursuing if you need them. But the absence of a signed diagnosis is not a locked gate in front of your recovery. You are allowed to start healing today, exactly as you are, with no one's permission and no paperwork required. (More on the system side in What Better Care Requires.)
When Herman defined Complex PTSD, she also gave us a map out of it. Recovery, she argued, tends to move through three stages. Not in a tidy line, but as a rhythm you return to again and again. You don't have to do them in order, and you don't have to do them perfectly. You just have to start where you are.
Before anything else, the body needs to learn that the danger has passed. This stage is about steadying the nervous system, building routines that feel predictable, and learning concrete skills to ride out distress. This is the most available starting point for almost everyone, and you can begin it today with Regulation Tools and the skills in DBT.
Once there's enough stability to hold it, healing involves facing what happened and grieving what it cost: the lost time, the lost safety, the childhood or relationship that should have been. This is deep work, usually done with support. Explore Therapy Types and Healing Trauma to understand what that can look like.
Recovery completes itself not in the past but in the present: rebuilding trust, relationships, identity, and a life that feels like yours. This is where the work becomes about living, not just surviving. See Connection, Relationships in Recovery, and Identity, Values & Beliefs.
Healing is when what happened no longer gets to decide who you are.
And the doors into that work are almost always closer than they feel. Most people don't lack the capacity to begin. They lack a starting point and permission. Consider this page both. If you're not sure where to step in, my Start Here guide will walk you to the first handhold.
