ISTSS 42nd Annual Meeting: the field's global trauma-science forum, San Antonio, September 2026

Trauma work moves quickly, and no single journal keeps pace with all of it at once. The most efficient way to see where the evidence base is actually heading – across PTSD, complex PTSD, moral injury, dissociation and prevention – is to follow the ISTSS Annual Meeting, the annual point at which the field's clinical and research communities compare notes in the same room. The 42nd meeting runs 23–26 September 2026 in San Antonio, Texas, and registration and the call for proposals are already open.

What the meeting actually offers

ISTSS is not a commercial training vendor; it is the professional society whose members produce the "Posttraumatic Stress Disorder Prevention and Treatment Guidelines" that many national services draw on. That gives the meeting a specific character: symposia and keynotes track the primary literature rather than a proprietary method, and the debates in the room often precede the guideline revisions that follow. The four days combine keynote addresses, symposia and poster sessions with Pre-Meeting Institutes – intensive half- and full-day workshops taught by senior clinicians on assessment, formulation and specific treatment protocols.

One feature makes the meeting usable well beyond the well-funded Western institutions that typically dominate such events: ISTSS runs sliding-scale registration keyed to the attendee's country of residence, so colleagues residing in many countries outside the US, Canada, Western Europe, Australia and New Zealand are not charged the full North American rate. The meeting also carries accredited continuing-education credit, which matters for clinicians who must document CPD hours.

For those who cannot attend in person, ISTSS sells recordings of prior annual meetings, so the scientific content is not entirely gated behind travel. The 2026 program itself is still being assembled through the open call for proposals, so the detailed schedule will firm up over the coming months.

Who should go, and how to use it if you cannot travel

The natural audience is any clinician whose caseload is trauma-heavy – psychologists, psychiatrists, and social workers working with PTSD, complex PTSD, childhood maltreatment sequelae, dissociative presentations, or trauma in refugee and displaced populations – plus researchers and trainees. If you can travel, the highest-yield move is to pair one Pre-Meeting Institute (deep skills in a protocol you already use) with symposia in an area you are weaker in, rather than grazing broadly.

If a US trip is not realistic – whether on cost, time, or visa grounds – the meeting is still worth tracking. Watch the published program and abstract book to see which interventions and biomarkers are gaining traction before they reach textbooks; buy recordings of the sessions that matter to your practice; and read the ISTSS guidelines the society keeps current. Used that way, the meeting functions as a yearly calibration point for a trauma practice, whether or not you are in the room in San Antonio.
