Abstract

Purpose
Despite empirical evidence suggesting complex associations between psychological trauma, substance misuse, and violent offending, there is a dearth of research investigating these associations in the female prison population.
Methods
A cross-sectional, interview-format questionnaire study was undertaken with a sample of 89 female prisoners. History of traumatic events, DSM-5 PTSD, drug use, and offending behaviour were assessed.
Results
Traumatic experiences had occurred in 97.8 % of the sample, while 60.5 % met criteria for a PTSD diagnosis. The majority of the sample (70.8 %) reported using illicit drugs, and 59.6 % had committed at least one violent offence. History of drug use was significantly correlated with trauma, PTSD status, and violent offending. A mediation analysis identified an indirect effect of PTSD symptoms on the relationship between history of drug use and violent offending.
Conclusions
The result of our mediation analysis further highlights the importance of addressing PTSD symptoms and substance misuse, among female offenders, to help prevent violent offending.
