Three Trauma Conferences That Define 2026: From cPTSD London to ISTSS San Antonio to DBT in Asia-Pacific

If you treat trauma, 2026 offers an unusually concentrated set of professional development opportunities. Three events, three continents, three distinct angles on the same clinical territory. Here is what each one delivers and why it matters.

ISTSS San Antonio: the field's annual reckoning

The ISTSS Annual Meeting is the premier international trauma conference. Not one of the premier conferences. The premier conference. It is where treatment guidelines get debated before they become official, where ICD-11 cPTSD implementation data gets presented for the first time, and where the tension between research and clinical reality plays out across four days.

The 42nd meeting lands in San Antonio, September 23-26. The theme — "Frontiers in Traumatic Stress: Global Perspectives and Creative Solutions" — signals emphasis on non-Western trauma research and implementation science in resource-limited settings. Mary-Frances O'Connor delivers the keynote on the neuroscience of grief and prolonged grief disorder, a topic that gained clinical urgency after PGD entered the DSM-5-TR. Her book The Grieving Brain (2022) and follow-up The Grieving Body (2025) have reshaped how clinicians think about bereavement as a learning process rather than a stage sequence.

The call for proposals is already open. Registration is live at the conference site. For trauma clinicians who have never attended ISTSS: this is the event where you discover what the field actually looks like beyond your local training ecosystem.

BPS London: cPTSD in clinical close-up

Six months earlier, a more focused event. The British Psychological Society's 2nd International Complex PTSD Conference runs March 19-20 in London. Where ISTSS covers the full trauma spectrum, this event zeroes in on cPTSD — the diagnosis that changed how we conceptualize the aftermath of sustained interpersonal trauma.

The scientific leadership is not accidental. Marylene Cloitre was on the WHO ICD-11 working group that developed the cPTSD diagnosis. She built STAIR Narrative Therapy. She received the 2025 ISTSS Lifetime Achievement Award. Thanos Karatzias, co-lead, is the editor of Traumatology and has spent his career on the effects and treatment of interpersonal trauma, including work with prison and veteran populations and people with learning disabilities.

Day 1 at the Courthouse Hotel Shoreditch is the conference proper — mechanisms, formulation, evidence-informed approaches. Day 2 at the BPS London Office offers two masterclasses taught by the developers themselves: the International Trauma Interview (ITI) and Enhanced Skills Training in Affective and Interpersonal Regulation (ESTAIR). Each masterclass is capped at 40 participants. This is not a lecture. It is direct clinical skills transfer from the people who created the tools.

Pricing: Non-member £210 / BPS member £195 / CDT member £165 (Day 1). Day 2 masterclasses are additional. Note: Registration for March 2026 has closed. Contact BPS for waitlist or future events. Details: bps.org.uk/event/international-complex-trauma-conference

APAC-DBT: DBT takes root in the Asia-Pacific

The third development is structural, not a single event. The Asia-Pacific Association for DBT — a regional chapter of the World DBT Association — is building the infrastructure for DBT training and quality standards across the region. Formed in 2023, formally registered in Australia in 2025, led by Shian-Ling Keng (Sunway University, Malaysia) and Chun Wang (Nanjing Brain Hospital, China).

Their 2026 training calendar matters for trauma clinicians specifically because it includes DBT for Trauma: an introduction to the DBT Prolonged Exposure protocol (September 2026). DBT-PE is the protocol for treating PTSD within DBT — developed by Melanie Harned, it integrates prolonged exposure into standard DBT for patients who are actively suicidal or self-harming. This is the treatment that addresses the population most other PTSD protocols exclude.

Other 2026 events include DBT Skills Training Application and Adaptation in China (May), Targeting Shame in DBT (April), DBT for People with Disorders of Intellectual Disability (July), and Effective Phone Coaching in DBT (August). For clinicians in Australia, New Zealand, Singapore, Malaysia, China, Japan, Indonesia, and Hong Kong — this is the first time a coordinated, quality-controlled DBT training infrastructure exists at the regional level.

Planning your 2026

The sequence is logical. London in March for focused cPTSD clinical skills — if you can get off the waitlist or catch future BPS offerings. San Antonio in September for the full panorama of trauma research and practice. APAC-DBT events throughout the year for Asia-Pacific clinicians building DBT competency.

ISTSS recordings are available for purchase after the event if travel is not feasible. The BPS conference was in-person only. APAC-DBT events are primarily online, making them accessible regardless of location.

Budget the ISTSS meeting first. It is the single highest-density professional development event in the trauma field. Everything else calibrates against it.
