Autistic Adults Experience Higher PTSD Symptoms Relating to Motor Vehicle Accidents than Non-Autistic Adults.
Article in Journal of autism and developmental disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAutistic adults experience high rates of traumatic events and PTSD. However, little work has evaluated motor vehicle accident (MVA) related trauma symptoms. The goal of this brief report was to provide pilot data characterizing MVA-related peritraumatic reactions, trauma symptoms, and rates of PTSD diagnosis and mental health service use among Autistic compared to non-autistic adults.
methodParticipants were 637 adults in the United States (276 Autistic, 361 non-autistic) who completed an online survey assessing MVA experiences. Participants provided information about peritraumatic reactions to the accident, and whether they were diagnosed with PTSD or sought mental health services relating to the MVA. Participants also completed the Posttraumatic Symptom Checklist for DSM-5 (PCL-5) in relation to the worst MVA experienced.
results48.7% of Autistic adults had experienced an MVA relative to 64.5% of non-autistic adults. Of those who experienced an MVA, Autistic adults reported higher peritraumatic dissociative reactions, and higher MVA-related total, negative mood/cognition, and hypervigilance PTSD symptoms than non-autistic adults, when adjusting for covariates. Autistic adults were significantly more likely to have sought mental health treatment relating to the MVA (11.9% compared to 0.9% of non-autistic adults), and to have received a PTSD diagnosis relating to the MVA (5.9% compared to 0.4% of non-autistic adults).
conclusionAutistic adults reported higher levels of trauma-related sequalae in response to MVAs than non-autistic adults. Future research should examine MVA-related trauma in more diverse samples, and develop assessment and support strategies to better identify, prevent, and reduce trauma-related symptoms post MVAs for Autistic people.
