The story at a glance

A review article in Nature Reviews Psychology by Iris M. Engelhard, Angelos-Miltiadis Krypotos, Richard J. McNally, Gaëtan Mertens, and Mirjam van Zuiden examines ongoing debates about what counts as psychological trauma since PTSD's formal recognition over 40 years ago. The authors link issues with the current "traumatic event" definition to empirical studies and theories like cognitive-behavioural models and active inference. This appears now amid heightened exposure to stressors from the COVID-19 pandemic, wars, racism, and social media. PTSD requires DSM-listed symptoms after exposure to an objectively defined traumatic event.[[1]](https://www.nature.com/articles/s44159-026-00557-y)

Key points

Critiques the DSM's requirement for an "objectively defined traumatic event" as overly narrow, sparking research surges and debates.
Connects definitional problems to findings on direct and indirect causality in trauma.
Reviews cognitive-behavioural approaches and active inference models for understanding trauma responses.
Highlights relevance in today's context: COVID-19 pandemic, ongoing wars, racism-related stressors, and social media distress.
Argues for a more encompassing trauma definition's clinical utility.
Weighs positive and negative clinical and societal implications of revising the concept.
Includes figures on categorizing traumatic versus non-traumatic events and active inference applications to PTSD.[[1]](https://www.nature.com/articles/s44159-026-00557-y)

Details and context

The review builds on PTSD's establishment in the DSM over 40 years ago, which tied the disorder to specific events like death threats or serious injury. This led to questions about subjectivity: not everyone exposed develops symptoms, and some report trauma from less "objective" stressors.[[1]](https://www.nature.com/articles/s44159-026-00557-y)

Authors draw on empirical work and theories to propose rethinking trauma beyond strict criteria, potentially including indirect exposures relevant to modern life. They note no competing interests and funding from a Dutch Research Council grant to lead author I.M.E. Full text is paywalled, limiting access to abstract and metadata.

Why it matters

Narrow trauma definitions may overlook common modern stressors like social media or racism, affecting PTSD research and diagnosis. Clinicians and patients could see expanded criteria improve access to care but risk overpathologizing normal distress. Watch for DSM updates or studies testing broader definitions, though societal effects remain debated.[[1]](https://www.nature.com/articles/s44159-026-00557-y)
