Experiences of Trauma and PTSD Symptoms in Autistic Adolescents: Preliminary Findings

Lau-Zhu et al. (2026) · Clinical Child Psychology and Psychiatry 2026
★ The Verdict

Autistic teens screen positive for PTSD at rates matching maltreated youth—check for PTSD even when the index event seems ‘mild’.

01Research in Context

01

What this study did

Lau-Zhu et al. (2026) asked if autistic teens show PTSD as often as kids who were maltreated. They compared three groups: autistic teens, maltreated youth, and typically-developing peers. Everyone filled out the same PTSD checklist. The study used a quasi-experimental design, so no one was randomly placed.

02

What they found

Autistic teens scored just as high on PTSD symptoms as the maltreated group. Both groups scored far above the typically-developing teens. In plain words, an autistic teen who seems to have had a "small" upset can still screen positive for PTSD.

03

How this fits with other research

Rumball et al. (2020) and Rumball et al. (2021) saw the same pattern in autistic adults. They found over 40% of trauma-exposed adults met PTSD thresholds. Lau-Zhu extends that warning downward to teens.

Brenner et al. (2018) looked at autistic in-patients with known abuse. They also saw more trauma signs, but only in kids who already had an abuse record. Lau-Zhu shows you can’t relax screening just because nothing "big" is on file.

Kildahl et al. (2020) found weaker links between trauma and behavior scores in adults with ASD plus ID. That sounds like a clash, but they used different measures (ABC irritability, not PTSD scales) and included intellectual disability. Method difference explains the gap.

Why it matters

If you work with autistic teens, add a quick PTSD screener to your intake. A meltdown, self-injury, or sudden skill loss might be trauma talking, not "just autism." Treat the PTSD first and your behavioral plan will stick better.

03Original abstract

Psychological trauma and post-traumatic stress disorder (PTSD) are under-researched in autistic individuals. We explored the experience of trauma and PTSD symptoms in a sample of autistic adolescents (n = 30) aged 10–16 years (without a maltreatment history; 47% female), compared to a group of typically-developing (TD; n = 29) and a group of (non-autistic) maltreatment-exposed adolescents (n = 28), matched on key demographics. Caregiver reports indicated that a wide range of events were deemed traumatic to autistic adolescents, including those not meeting DSM-5’s Criterion A for trauma for a PTSD diagnosis (e.g., bullying and bereavement). Caregiver- and self-reports converged to show more severe PTSD symptoms, and higher rates of probable PTSD, in autistic adolescents (43–57%) relative to the TD adolescents (7–32%). Symptom severity and rates of probable PTSD were comparable between the autistic and maltreatment-exposed adolescents (50–54%), except that, for autistic adolescents, the index trauma mostly did not match DSM-5 criteria, whereas it did for maltreatment-exposed adolescents. This short report’s early findings supports the need for improved assessment of trauma exposure and PTSD symptoms in autistic adolescents. A flexible approach to how trauma is defined in this population may be needed, considering subjective experiences and autism-related processing differences.
