Survivors of sexual trauma exhibit elevated symptoms of post-traumatic stress disorder (PTSD) and slower symptom recovery following a subsequent nonsexual trauma than survivors of nonsexual trauma, a case-control study has revealed.
Sexual violence is alarmingly common
In the longitudinal case-control study using data from the Advancing Understanding of Recovery After Trauma (AURORA) study, 2,423 participants (mean age, 36 years; female, 36.6 percent) admitted to the emergency department for nonsexual traumatic injury, primarily motor vehicle crashes, were assessed at five time points, including 2 weeks, 8 weeks, 3 months, 6 months, and 12 months post-injury. [JAMA Psychiatry 2026;doi:10.1001/jamapsychiatry.2026.2219]
In this large, diverse, multisite sample across the US, 52 percent of participants, 24 percent of whom were male, reported a prior history of sexual violence, as assessed at emergency department admission by the Childhood Trauma Questionnaire and the Life Events Checklist.
These findings were broadly consistent with Centers for Disease Control and Prevention (CDC) data, showing nearly half of women and more than one in six men experienced some form of contact sexual violence during their lifetimes.

More severe & persistent PTSD over 1 year
Individuals with a history of sexual violence demonstrated significantly elevated symptoms of PTSD across time points (β, 4.62; 95 percent confidence interval [CI], 3.09–6.21; p<0.001) vs those without prior sexual violence, even after controlling for earlier nonsexual trauma exposure.
The proportion of participants meeting the criteria for probable PTSD, defined as PCL-5 score ≥31, was significantly greater in the group subjected to prior sexual violence (p<0.001 for all) vs those without prior sexual violence, with absolute differences ranging from 19 to 22 percent across time points.
Individuals subjected to prior sexual violence recovered significantly more slowly from the current index trauma at week 8 (ß, 0.92; 95 percent CI, 0.84–0.99; p<0.001), month 3 (ß, -0.27; 95 percent CI, -0.49 to -0.05; p=0.02) and month 12 (ß, 0.88; 95 percent CI, 0.36–1.42; p=0.002) vs those without prior sexual violence.
“These findings suggest that earlier sexual violence may shape how people respond to subsequent nonsexual traumas,” commented the researchers.
Among individuals subjected to prior sexual violence, hypervigilance remained the most severe PTSD symptom across five time points, whereas negative alterations in cognition and mood recovered most slowly.
Clinical implications
“Exposure to sexual violence may be an important risk factor for PTSD not only immediately after the sexual violence, but also after a subsequent nonsexual trauma,” pointed out the researchers.
“Clinicians across all healthcare specialties should be aware that they will frequently work with survivors of sexual violence, even when patients do not disclose this history and when their presenting concern is unrelated to sexual violence,” advised the researchers. “Awareness of a patient’s prior sexual violence history can improve the quality of care by encouraging treatment teams to adopt trauma-informed approaches.”
