Traumatic events (in particular, multiple and repeated traumatic events) have been linked with an increased risk of developing psychosis. Clinical guidance recommends the use of interventions recommended for post-traumatic stress disorder (PTSD) for trauma-focused work with people experiencing psychosis. As an intervention developed specifically for use with people reporting multiple trauma histories, Narrative Exposure Therapy (NET) may be an appropriate and beneficial intervention for this group.

Part 1 is a qualitative meta-synthesis. Thirty two qualitative studies of first-hand accounts of psychosis were reviewed and synthesised, with the aim of exploring connections made by Experts by Experience (EbE) between their experiences of traumatic events and of psychosis. Findings indicate that people link a broad range of traumatic events and life stressors to the onset of psychosis, and outline some of the pathways by which EbE link past events with subsequent psychosis experiences.
Part 2 is a qualitative study exploring EbE and clinician experiences of NET in an Early Intervention in Psychosis (EI) service. Interviews were conducted with four EbE and eight clinicians, and analysed using thematic analysis. The findings suggest that NET is a meaningful and emotionally-demanding intervention which can help people create a new ‘unburdened’ relationship with traumatic memories. Considerations are shared related to the preparation for and monitoring of distress during the intervention, as well as psychosis-specific factors relevant to the implementation of NET in EI services.

Part 3 is a critical appraisal of the research process. It explores dilemmas and reflections related to the conceptualisation of trauma in clinical work and research, experience of the role transition from ‘clinician’ to ‘researcher’, and reflections related to power and social identity.
