Résumé
Violence is a common problem in prisons. Post-traumatic stress disorder (PTSD), a prevalent disorder in prison populations, has been identified as a risk factor for violent behaviour in community and military populations. Although cross-sectional associations between PTSD and prison violence have been documented, prospective cohort studies are required. To investigate whether PTSD is an independent risk factor for prison violence, and examine the potential role of PTSD symptoms and other trauma sequelae on the pathway from trauma exposure to violent behaviour in prison. A prospective cohort study was conducted in a large, medium security prison in London, UK. A random sample of sentenced prisoners arriving into custody ( Prisoners who met current (past month) criteria for PTSD were more likely to engage in violent behaviour during the first 3 months of imprisonment, after adjusting for other independent risk factors. The relationship between lifetime exposure to interpersonal trauma and violent behaviour in custody was mediated by total PTSD symptom severity. Hyperarousal and negatively valenced cognitive and emotional appraisal symptoms were particularly implicated in this pathway. The identification and treatment of PTSD has the potential to reduce violence in prison populations.

RESULTS
RESULTS
Prisoners who met current (past month) criteria for PTSD were more likely to engage in violent behaviour during the first 3 months of imprisonment, after adjusting for other independent risk factors. The relationship between lifetime exposure to interpersonal trauma and violent behaviour in custody was mediated by total PTSD symptom severity. Hyperarousal and negatively valenced cognitive and emotional appraisal symptoms were particularly implicated in this pathway.
CONCLUSIONS
CONCLUSIONS
The identification and treatment of PTSD has the potential to reduce violence in prison populations.
