Objective: This paper presents the case of a forensic inpatient who was found ‘Not Guilty by Reason of Mental Illness’ for the murder of his mother and illustrates how psychotic symptoms can mask trauma symptoms, leading to neglect in the treatment of trauma in psychotherapy with forensic inpatients.

Method: A case study of a forensic inpatient diagnosed with schizophrenia that as part of his rehabilitation program received 19 sessions of therapy (i.e. grief counselling, Trauma-Focused Cognitive Behavioural Therapy (TF-CBT) and imagery rescripting). The following measures were administered pre- and post-treatment: (a) The Depression Anxiety Stress Scale (DASS), to measure symptoms of depression, anxiety and stress; (b) The Impact of Events Scale-Revised (IES-R), to measure post-traumatic stress symptoms; and (c) The Trauma Attachment and Beliefs Scale (TABS), to measure disruption in beliefs about self and others.

Results: At completion of therapy, he showed a reduction in Post-Traumatic Stress Disorder (PTSD), depression, anxiety and stress symptoms.

Conclusions: Trauma and PTSD-related symptoms in the forensic inpatient population must be assessed and treated alongside psychotic symptoms, where relevant. TF-CBT was effective in reducing PTSD symptoms in this current case study and should be considered as an intervention in forensic inpatient populations.
