Plain English Summary
Background and study aims
This is a study of Eye Movement Desensitization and Reprocessing (EMDR) therapy for patients suffering early psychosis (patients with a schizophrenia or related diagnosis who experience hallucinations and/or delusions) who have experienced significant trauma in their life. EMDR is a proven and NICE-recommended treatment for Post-Traumatic Stress Disorder PTSD); it involves recalling traumatic events while performing eye-tracking under the direction of a therapist, usually by following the therapist's finger movements. It is thought that this processes leads to recoding of the traumatic experiences in the brain so that the memories no longer evoke strong negative emotion. This treatment is worth considering for patients with psychosis because previous work has shown that many have a history of severe trauma and because a trial carried out in the Netherlands with patients suffering from both psychosis and PTSD had positive effects.The main aim of this study is to collect data that will inform the design of a large, multi-site definitive trial.
Who can participate?
Service users aged at least 16 years with early psychosis
What does the study involve?
Participants are randomly allocated to either EMDR plus Treatment As Usual (TAU). Those receiving EMDR are offered up to 16 sessions over 6 months with an experienced EMDR therapist. Follow-up interviews are conducted by research assistants 6 and 12 months later, who assess psychotic symptoms. Interviews with patients and service staff are also conducted to assess the acceptability of the treatment.
What are the possible benefits and risks of participating?
This study does not involve any known physical risks or harm to participants or the researchers. However, talking about personal experiences and feelings may be difficult and can cause emotional upset. The protocol for assessing and reporting risks and the distress protocol for the current study will be followed in such cases.
Where is the study run from?
Lancashire Care NHS Foundation Trust (UK)
When is the study starting and how long is it expected to run for?

Schizophrenia, schizotypal and delusional disorders
60 patients who have been ill for a maximum of three years will be randomly assigned to either Eye Movement Desensitisation and Reprocessing adapted for psychosis (EMDRp) plus Treatment As Usual (TAU) or TAU only at a ratio of 1:1. Randomisation will be achieved by means of concealed random allocation conducted by the study statistician using an online pseudo-random list hosted by sealedenvelope.com with random permuted blocks of varying sizes. Allocation will be concealed from the RAs who will conduct post-randomization assessments. Those receiving EMDR will be offered up to 16 sessions over 6 months with an experienced EMDR therapist.
Participants allocated to the intervention arm will receive up to 16 sessions of EMDRp delivered over a 6-month treatment window, in addition to TAU. Each session will last up to 90 minutes and will be audio-recorded for fidelity monitoring purposes.
Comparator: Treatment As Usual (TAU)
TAU will be in line with all standard and individually prescribed clinical interventions as directed by national clinical guidelines for psychosis and the participants’ clinical team, and may include antipsychotic medications and/or psychological interventions (CBT, family therapy). Although EMDR is not routinely employed in the treatment of psychosis, TAU participants with comorbid PTSD may be referred by their clinical teams to other services to receive a trauma-focused intervention (TF-CBT or EMDR), as per NICE guidelines for PTSD. For ethical reasons (and in the light of recommendations voiced during PPI consultations the trialists conducted to develop this project), clinical teams will not be asked to withhold such referrals/interventions. Instead, the trialists will carefully monitor the care received by TAU participants (through case notes reviews after the 12-month assessment) to examine the proportion of TAU participants who received EMDR.
Follow-up interviews will be conducted by research assistants who are blind to the group assignment at 6 and 12 months after randomization, who will assess psychotic symptoms. Qualitative interviews with patients and service staff will also be conducted to assess the acceptability of the treatment.
Primary outcome measure
Feasibility assessed after completion of 6 and 12 months battery assessment follow-ups by calculating:
1. Recruitment rate: the number of participants consented into the trial and randomised
2. Therapy/assessment retention: % who drop-out of therapy
3. Therapy fidelity: % who did not receive treatment allocated
4. Adherence: ratings from therapy tapes
5. Therapy safety: number of Serious Adverse Events (SAEs)
Secondary outcome measures
Measured at baseline, 6 and 12 months:
1. Psychotic symptoms measured using:
1.1. The PANSS, the most widely-used research measure to assess the severity of positive and negative symptoms of psychosis as well as symptoms of general psychopathology
1.2. The Psychotic Symptoms Rating Scales, a semi-structured interview completed alongside the PANSS to provide a more fine-grained assessment of auditory hallucinations and delusions, including measures of subjective distress caused by these symptoms
1.3. The Green et al. Paranoid Thoughts Scale, a brief self-report questionnaire assessing paranoid thinking and persecutory delusions.
2. Trauma exposure and trauma-related difficulties, measured using:
2.1. The TSQ, a brief measure used to screen for trauma exposure and post-traumatic stress. In the present study, the modified version of the TSQ developed by de Bont and colleagues for use in people with psychosis will be used to check the participants’ potential eligibility in this trial
2.2. The Trauma and Life Events checklist (TALE), a measure specifically designed to assess exposure to adverse and traumatic life experiences that are commonly reported by people with psychosis
2.3. The PTSD Checklist for DSM-5, a self-report questionnaire assessing the presence and severity of post-traumatic symptoms.
2.4. The 12-item version of the International Trauma Questionnaire (ITQ), a brief measure assessing the severity of symptoms of PTSD and complex PTSD as defined in the recently published ICD-11.
2.5. The Dissociative Experiences Scale-II, a self-report measure of dissociation.
3. Health economic measures:
3.1. The EQ-5D-5L (Devlin et al., 2018; Jansen et al., 2013), a health status questionnaires used in health economics analyses.
3.2. An adapted version of the Economic Patient Questionnaire, and health economics measures developed by co-applicant Davies and used in previous NIHR-funded mental health trials.
4. The Generalized Anxiety Disorder Questionnaire and the Patient Health Questionnaire, two brief and widely-used questionnaires assessing symptoms of anxiety and depression.
5. The Personal and Social Performance Scale, a scale assessing patients’ functioning in four areas (socially useful activities, personal and social relationships, self-care and disturbing/aggressive behaviours).
6. The Questionnaire about the Process of Recovery, a service user-defined measure of subjective recovery.
7. Case notes review: after the 12-month assessment, the trial manager will contact the participants’ care co-ordinators and ask them to review their clinical notes and document the interventions each participant received during the study duration period

Results and Publications
Publication and dissemination plan
Dissemination will target all potential beneficiaries of this research, including mental health services, the academic community, service users and the general public. The team has strong links with NHS services (many are NHS clinicians) and organisations concerned with training and implementation of psychological therapies (e.g. Bhutani is chair of the Psychological Professions Network North West), as well as an extensive track-record of successful EMDR training for NHS staff locally and nationally (e.g. Logie is an experienced EMDR trainer and supervisor, and former president of the EMDR Association UK and Ireland; the team has already organised successful conferences/workshops on EMDR for psychosis for NHS clinicians).This will lead to immediate dissemination of our findings in the clinical community.
The trialists have a strong and sustained track record of clinical dissemination achieved through the delivery of research presentations and clinical workshops through professional organisations (BABCP, EMDR Association UK & Ireland), and they will continue their practice of presenting our research findings at major national and international conferences for mental health researchers and practitioners (e.g. BABCP conferences, the Biennial Schizophrenia International Research Society Conference).
The team has a sustained track-record of publications in high-impact journals and we will publish the findings of this feasibility study in peer-reviewed open-access journals. They also have a strong record of engagement with the media to promote public understanding of psychosis and mental health difficulties (in particular Bentall) and excellent links with mental health charities and service user organisations (e.g. the Hearing Voices Network, Mind). They will work with the members of the C-TRU Lived Experience Group to promote dissemination amongst service users to identify further opportunities for dissemination amongst service users, carers and the general public throughout the lifetime of the project.
IPD sharing statement
The PI, key investigators and collaborators will be responsible for access to the participant data, audio recordings and consent forms. The consent forms may also be accessed by LCFT staff from which the participant is recruited for audit purposes.
All relevant data security and confidentiality standards will be applied as per the University of Manchester Research Data Management Policy and relevant LCFT policies. Consent forms and paper copies of assessment tools will be stored in locked filing cabinets in secured offices within LCFT. All anonymised, computerised data will be encrypted and password protected and replicated on the LCFT server. Additional electronic copies of the data will be stored using the University of Manchester Research Data Management Service, which provides robust, managed, secure replicated storage. The RDMS allows researchers to store, manage and curate their data, as well as preserve data after project completion. Sufficient meta-data capturing content, quality, condition, and other relevant characteristics of datasets will be recorded to enable future efficient use of the data generated as part of this study. Hardcopy will be stored securely in accordance to the LCFT Good Research Guidelines Policy, which states that primary research data (and where possible/relevant specimens, samples, questionnaires, audiotapes, etc.) must be retained in their original form within the research establishment that generated them for a minimum of ten years from completion of the project (NHS Code of Practice Records Management).
The trial will be coordinated at LCFT under the direct supervision of the PI and with support from Bentall, Sellwood and trial manager Aseem. The study will be managed by the Trial Management Group and will follow MRC Good Clinical Practice in RCT guidelines, and appropriate Ethics and Research Governance arrangements to ensure minimisation of security risk.
