Most people with psychosis have experienced significant trauma at some point in their lives. Childhood adversity, sexual assault, community violence, racism, immigration trauma, and the trauma of psychiatric hospitalisation itself are all common in this population. Despite this, formal trauma treatment has historically been withheld from people with psychosis on the assumption that the work would be destabilising. The evidence over the last decade has flipped that assumption: trauma-focused CBT can be delivered safely and effectively to people with psychosis when adapted thoughtfully, and may reduce both PTSD symptoms and some voice and paranoia symptoms.
Trauma-focused CBTp combines the stabilisation, narrative, and meaning-making elements of evidence-based PTSD treatment with the engagement and safety adaptations of CBT for psychosis, so people with both conditions can be treated for both rather than only one.
Why trauma matters in psychosis
A large body of epidemiological work, summarised by the World Health Organization and others, links childhood adversity to a roughly two- to three-fold increase in lifetime psychosis risk. Trauma is not the cause of schizophrenia, but it is one of the strongest modifiable risk factors. Beyond risk, trauma shapes the content of psychotic symptoms: persecutory voices often echo the words of past abusers, and themes of being watched or pursued frequently mirror real past experiences of being unsafe.
The core methods adapted for psychosis
Three trauma therapies have been adapted for use in psychosis:
- Trauma-focused CBT (TF-CBT) and Cognitive Processing Therapy (CPT). Structured work on trauma memories, beliefs about self and the world, and avoidance behaviours.
- Prolonged Exposure (PE). Repeated, paced revisiting of the trauma narrative until distress decreases.
- Eye Movement Desensitisation and Reprocessing (EMDR). Bilateral stimulation paired with brief recall of traumatic material.
Adaptations for psychosis include longer stabilisation phases, more frequent grounding work within sessions, careful pacing of exposure, integration with antipsychotic treatment, and explicit attention to voices and beliefs that may be triggered. See our overview of trauma-focused CBT for psychosis and EMDR and psychosis for related coverage.
Who is a candidate
Patients are usually considered for trauma-focused work when:
- They meet criteria for PTSD or have clinically significant trauma symptoms
- Their psychosis is on the more stable end (no acute disorganisation, controlled command voices)
- They have a stable living situation and a treatment team to wrap around the work
- They have explicit interest in addressing the trauma — coercion is contraindicated
Phases of treatment
Phase 1: Stabilisation and engagement
Often longer in psychosis than in standard PTSD treatment — sometimes 4–8 sessions. The clinician builds the alliance, teaches grounding skills (see grounding techniques), maps current voices and beliefs, and establishes a shared language for what is "trauma flashback," what is "voice," and what is "in the room."
Phase 2: Trauma processing
Depending on the protocol, this is the narrative reconstruction (TF-CBT/CPT), the imaginal exposure (PE), or the bilateral stimulation work (EMDR). The clinician monitors voices, paranoia, dissociation, and sleep before and after each session and adjusts pacing. The person may take longer to "drop into" trauma material because of cognitive symptoms; that is fine and not a contraindication.
Phase 3: Integration and meaning
Cognitive work on the beliefs the trauma created — about self ("I am dirty"), others ("Everyone is dangerous"), and the future ("Nothing good can happen") — and on how those beliefs interact with the meaning the person has made of their psychosis.
What the evidence says
Trials such as the Dutch T.TIP study and several UK pragmatic trials have shown that trauma-focused work in psychosis reduces PTSD symptoms with effect sizes similar to those in non-psychotic samples, without an increase in adverse psychiatric events. Some studies show modest secondary reductions in voice severity and paranoia. The NICE PTSD guideline now explicitly states that PTSD treatment should not be withheld solely because someone has psychosis.
Common adaptations
- Sessions slightly shorter or split into two halves to manage cognitive load
- Anti-dissociation grounding integrated at the top and tail of every session
- Use of written narratives in addition to spoken work for people for whom speaking is harder
- Explicit safety planning around voice content that mirrors past trauma
- Coordination with the prescriber so antipsychotic doses are not changed during active processing
If trauma work — at any point — increases thoughts of self-harm, severe dissociation, or destabilises voices, pause the work and contact your team. Pausing is not failure; it is the protocol.
Where to find this work
- Specialist psychosis clinics, particularly those linked to academic centres
- Coordinated specialty care programmes for first-episode psychosis
- Veterans Affairs PTSD clinics, where some clinicians are trained for dual presentations
- Some private practitioners who have completed both EMDR and CBTp training

The big picture
For many people with schizophrenia, trauma is not a side story — it is the engine of much of the daily distress. Treating it directly, with proven methods adapted for safety, is one of the most underused tools in modern psychosis care. The work is harder than standard CBTp, takes longer, and requires a confident, well-supported clinician. But for the right person, at the right time, it can change what it means to live in their own head.
