ICD-11 Complex PTSD (6C58) diagnostic structure — core PTSD symptoms plus the three Disturbances in Self-Organization (DSO) domains · Original 24 items grounded in the ICD-11 diagnostic criteria, not the copyrighted International Trauma Questionnaire (ITQ) — we do not administer that instrument.
No. This is a self-reflection tool, not a clinical diagnosis. A formal Complex PTSD diagnosis under ICD-11 is made by a licensed clinician through a structured clinical interview — a short web check-in cannot replace that.
The Trauma Response Check-In screens for PTSD, which the DSM-5 and ICD-11 both recognize as a response to any distressing event, including a single incident. This check-in screens specifically for Complex PTSD, an ICD-11 diagnosis (6C58) tied to trauma that was prolonged or repeated over time, like ongoing childhood abuse, domestic violence, or captivity. It includes the same core symptoms as PTSD, re-experiencing, avoidance, and feeling on guard, plus three additional domains that PTSD alone doesn't cover: difficulty regulating emotions, a damaged sense of self-worth, and lasting difficulty trusting or feeling close to other people. If your difficult experience was a single event, the Trauma Response Check-In is the closer fit; if it happened repeatedly or over a long stretch of time, this check-in is built for that.
DSO is the clinical term ICD-11 uses for the three domains that distinguish Complex PTSD from PTSD: affect dysregulation (emotions that swing further and faster than feels manageable, or shut down entirely), negative self-concept (persistent shame, worthlessness, or feeling permanently damaged), and disturbed relationships (difficulty feeling close to or trusting other people). Research by Cloitre, Brewin, and colleagues found these three domains cluster together statistically in people who experienced prolonged or repeated trauma, which is why ICD-11 groups them as a distinct diagnostic feature rather than treating them as separate, unrelated problems.
Practical next steps: (1) In the UK, you can ask your GP for a referral, or self-refer to NHS Talking Therapies, and ask specifically about trauma-focused or complex-trauma treatment. (2) In the US, look for a licensed therapist who lists complex trauma, relational trauma, or attachment-based trauma treatment as a specialty. (3) The National Center for PTSD (ptsd.va.gov) publishes free, public information on evidence-based trauma treatment, regardless of military background.

The Complex Trauma & Relationship Patterns Check-In looks at patterns described in the ICD-11 diagnostic criteria for Complex PTSD (6C58): the same three core clusters as PTSD, re-experiencing, avoidance, and a persistent sense of current threat, plus three additional domains that only apply after trauma that was prolonged or repeated, not a single event: affect dysregulation, negative self-concept, and disturbed relationships. Together, clinicians call these three additional domains 'disturbances in self-organization,' or DSO.
Complex PTSD is understood as arising specifically from trauma that happened over a long time or over and over, childhood abuse or neglect, domestic violence, captivity, trafficking, ongoing war exposure, often at the hands of someone who was supposed to protect you. That's the key difference from PTSD, which can follow a single distressing event. This check-in exists because a single-event trauma screener doesn't capture the DSO domains, and a person living with complex trauma deserves language that names the fuller pattern.
This is a self-reflection tool, not a clinical diagnosis. If the results resonate or you are struggling, talk to a licensed professional experienced in complex trauma. Phase-based trauma treatment, EMDR (Eye Movement Desensitization and Reprocessing), and Cognitive Processing Therapy (CPT) are leading evidence-based approaches, and these patterns are genuinely treatable.
