Plain English Summary

Background and study aims
Psychosis affects over 600,000 people in the UK, many of whom have recurring persistent symptoms, despite medication. Symptoms include beliefs that people are conspiring against you (persecutory delusions) or hearing voices that are critical, abusive or command you to do unpleasant or harmful things (auditory hallucinations). The distress caused and the impact on day-to-day function can lead to hospitalisation and poor quality of life. Currently Cognitive Behavioural Therapy for psychosis (CBTp) is the only recommended individual talking therapy. CBTp can help people manage these distressing experiences leading to improved recovery and quality of life. However, 94% of NHS Trusts struggle to deliver it and fewer than 10% of patients receive it because of barriers like lack of knowledge about what CBTp is and does, pessimism about whether it works, strong medical beliefs, and a lack of hope and confidence in the ability to cope and change. A pre-CBT informed choice intervention has been developed to promote better, more informed, and more empowered offers and uptake of CBTp. The aim of this study is to test the draft pre-CBT informed choice intervention in a small-scale study.

Who can participate?
Service users with psychosis aged 16-65, and clinicians who work with people with psychosis in the NHS, from sites in London and Sussex

What does the study involve?
Each group (service users or clinicians) is randomly allocated to one of two groups. One group receives the digital pre-CBT ‘informed choice’ intervention, presented in a one-hour introductory session and made available to the participant for the subsequent month. The package includes basic information, interactive elements, animated stories and downloadable handouts. The other group use the CBT section of the NHS choices website, which is presented in a similar introductory session for up to one hour and provided as a printed handout for future reference. The trialists assess how easy it is to recruit, consent and retain people in the study up to the one month follow-up. The use of the new digital pre-CBT informed choice intervention is explored both through data obtained on page views on the website, and through a questionnaire and interviews with 6 service users and 6 clinicians who have used the intervention in Sussex and London. The interviews further explore feedback on the form and content of the digital intervention materials, including the acceptability of the materials and their use. The effect of the intervention on the likelihood of offering/referring CBTp (clinician) or taking up CBTp (service user) is measured. All participants complete a set of questionnaires before they look at the intervention packages, immediately after their introductory session, and at the one month follow up. Additional questionnaires measure attitudes towards CBT for psychosis, illness perceptions, attitudes towards CBTp within the NHS (clinicians only), psychological wellbeing (service users only) and empowerment. CBT-related activities in the preceding month are also collected at the start of the study and at one month follow-up, based on both interview and case notes.

What are the possible benefits and risks of participating?
It is anticipated that the intervention will be feasible, and that clinicians and service users will be more empowered, more knowledgeable and as a result more positive towards offering or taking up CBTp. There is a risk of disappointment if a service user or clinician is randomly allocated to receive the comparison intervention rather than the new informed choice intervention. However, this risk is mitigated by ensuring that those participants who are allocated to the comparison intervention are also provided with one month's access to the new information package at the end of the study. There is also risk of fatigue due to completion of a number of questionnaires, and distress when sensitive topics of wellbeing, health perceptions, empowerment and treatment are discussed.

Drug names

Primary outcome measure

1. Likelihood of offering/referring or taking CBT, measured by a single Likert scale (0-10) immediately post intervention and at one month follow-up
2. Feasibility of recruitment within the NHS (numbers recruited, consented) during the trial recruitment period August 2017- January 2018
3. Feasibility of use of the package in the NHS, measured using qualitative interviews with thematic analysis of 6 service users and 6 clinicians (3 each in Sussex and London) who have used the package; and evaluation form and activity data on use of the package, during the follow-up period September 2017 - February 2018

Secondary outcome measures

1. Knowledge and attitudes towards CBTp, measured using new questionnaires developed and validated with service users and clinicians during phase 1a and b of the current study, immediately post intervention and at one month follow-up
2. Illness perceptions, measured using the adapted illness perceptions questionnaire,immediately post intervention and at one month follow-up
3. Attitudes and Behaviours towards CBTp implementation, measured using the NOMAD tool (clinicians only), immediately post intervention and at one month follow-up
4. Psychological wellbeing, measured using the CHOICE short-form measure of psychological wellbeing (service users only) immediately post intervention and at one month follow-up
5. Empowerment, measured using Rogers' Empowerment scale, immediately post intervention and at one month follow-up
6. CBT-related activities in the preceding month, based on both interview and case notes screen, collected at baseline and at one month follow-up

Results and Publications

Publication and dissemination plan

The protocol and analysis plan will be published prior to the end of the study in June 2018.

Newsletters will be circulated by letter/e-mail and local websites to inform participants of study outcomes. A results ‘launch’ will be organised to which all participants and stakeholders will be invited. A series of talks and workshops will be open to service-users, families, health professionals, commissioners, GP’s and newly formed communities of practice led by service directors and managers. SURF and peer researchers will deliver talks and provide guidance on reaching out to service-users. Results will be presented from different perspectives (service user, clinician, trainer) and to a range of audiences (e.g. ISPSS/Tigger service-user conference, Hearing Voices Network). Locally, the results will be presented at SPRiG seminars and the R&D conference. Mental health charities will be contacted regarding publication in journals such as ‘One in Four’ and locally, on service-users websites, like ‘Sussex Voice’. The study team will present findings at regional and national psychological therapies meetings and international psychosis conferences. The main study papers will be published in Open Access formats so they are accessible free of charge. Questionnaires will be available on key websites (PRP, EYE, SPRiG). Significant publications are envisaged at each phase and to appropriate audiences (e.g. Behaviour Research and Therapy, Implementation Science, British Journal of Psychiatry). The aim is to submit all publications within one year of the end of the study in June 2019.

IPD sharing statement
Initial pilot data will not be made available as the trialists do not have consent for this level of data sharing. The plan is to use the data to support progression to a full RCT. Data will be stored electronically within Sussex Partnership NHS Foundation Trust according to ethical procedures.
