Research summary
Exceedingly high rates of victimisation and exposure to trauma have been identified in forensic populations (Bohle & de Vogel, 2017; Bruce & Laporte, 2015; Green et al., 2017; McKenna et al., 2019). To date, studies have predominantly examined past exposure to trauma, including adverse childhood experiences, and its association with other factors (e.g. psychological distress, psychiatric comorbidity, violence risk, and attachment), leaving posttraumatic stress disorder (PTSD) out of the equation. Only a few studies have explored PTSD in a UK forensic mental health or prison samples (Brackenridge & Morissey, 2010; McCallum, 2019; Papanastassiou et al., 2004; Sarkar et al., 2005). Studies have yet to examine the prevalence and clinically relevant outcomes of those who have developed PTSD within secure forensic mental health settings. The proposed study aims to examine the prevalence of PTSD in forensic psychiatric settings and explore associated clinically relevant outcomes, including engagement with treatment, risk of violence, and psychological distress, which have previously been explored only in association with past traumatic experiences rather than in the context of meeting clinical diagnostic criteria for PTSD. The study will utilise a cross-sectional design. The sample will consist of 100 male and female forensic psychiatric patients with a diagnosis of a psychotic disorder who have the capacity to provide consent and have the ability to complete the two outcome measures (PDS-5 and CORE-OM). Their risk and engagement in treatment will be assessed by their psychologist using the HCR-20v3 and the SES respectively. The study intends to add to the growing body of literature on PTSD and trauma-informed care in forensic mental health settings as well as to inform policy and practice at North London Forensic Service and other secure services in the UK.
