Plain English Summary

Background and study aims
Life can often become challenging for many people diagnosed with mental health difficulties. People’s confidence can take a large knock and it can be easy to be self-critical. People’s self-esteem can be low. The study team have designed a new Virtual Reality (VR) therapy with the aim of helping people to feel more confident. The VR therapy is called Phoenix. The purpose of this study is to see whether Phoenix is helpful for people. To do this, approximately half the participants will receive the Phoenix VR therapy (in addition to their usual care) and half of the participants will simply continue with their usual care. Whether a person has Phoenix VR therapy is decided by chance. The study team then compare how people who have Phoenix have got on compared to people who have not had Phoenix. Phoenix was designed for people with lived experiences of psychosis. Users enter VR simulations that provide experiences that are designed to help build up positive self-beliefs. There are up to six meetings with a Pheonix staff member. The Phoenix staff member helps support and advise.

Who can participate?
NHS patients aged 16-30 years old with low levels of positive self-beliefs.

What does the study involve?
Participants will complete a set of questionnaires at baseline. Participants will then be randomly allocated to one of two groups. The first group will receive Phoenix VR therapy (up to 6 weekly sessions) in addition to their usual care. The second group will continue to receive their usual care. Both groups will then complete another set of questionnaires at approximately 6 weeks and then again at 12 weeks in order to find out if there have been any changes. Whether a person has the Phoenix VR therapy will be randomly decided by a computer (rather like flipping a coin).

What are the possible benefits and risks of participating?
The study team hope that using virtual reality will help people feel more confident. The study team expect it also to increase psychological wellbeing, and activity levels, and improve mood. The trial aims to find out whether this is the case. There are unlikely to be any significant risks in participating, although occasionally people sometimes may get short-term motion sickness with VR.

2. Oxford Health NHS Foundation Trust (UK)
3. Berkshire Healthcare NHS Foundation Trust (UK)
4. Northamptonshire Healthcare NHS Foundation Trust (UK)
5. Central and North West London NHS Foundation Trust (specifically teams in the Milton Keynes area) (UK)

When is the study starting and how long is it expected to run for?
January 2021 to August 2024. The clinical trial will start in June 2023 and finish data collection in May 2024.

Who is funding the study?
A charity called the International Foundation. The study is also supported by the NIHR Oxford Health Biomedical Research Centre (UK)

Scientific titleThe Phoenix VR self-confidence therapy trial: a randomised controlled trial of automated VR therapy to improve positive self-beliefs and psychological wellbeing in young people diagnosed with psychosis
Study hypothesisOur primary hypothesis is that:
1. Compared to treatment as usual, Phoenix VR self-confidence therapy added to treatment as usual will improve levels of positive self-beliefs (end of treatment).

Our secondary hypotheses are:
1. Compared to treatment as usual, Phoenix VR self-confidence therapy added to treatment as usual will improve social comparison and psychological well-being (end of treatment).
2. Compared to treatment as usual, Phoenix VR self-confidence therapy added to treatment as usual will reduce depression, negative self-beliefs, hopelessness, anhedonia, anxiety, and paranoia and increase perceptions of recovery, meaningful activity, and quality of life (end of treatment).
3. Treatment effects will be maintained at follow-up (three months).
Ethics approval(s)Approved 22/05/2022, London - Harrow Research Ethics Committee (Level 3, Block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 (0)207 1048098; harrow.rec@hra.nhs.uk), ref: 22/LO/0273
ConditionNon-affective psychosis with low positive self-belief
InterventionParticipants will be NHS patients diagnosed with non-affective psychosis, with low positive self-beliefs, and aged 16-30 years old. It is a parallel group randomised controlled trial in which participants will be randomised to receive the intervention in addition to their usual care or will continue with their usual care. Participants will be allocated using a 1:1 allocation ratio. Randomisation will use a permuted blocks algorithm, with randomly varying block sizes.

The treatment being tested is Phoenix VR self-confidence therapy, which is a virtual-reality application recommended for adults (16+) attending psychosis services who have low levels of positive self-beliefs. The primary treatment goal is to help young people who have been given a diagnosis of schizophrenia (or related condition) to increase their psychological well-being by building up positive self-beliefs.

Phoenix is supported by a staff member in up to 6 meetings. In the first meeting, the staff member introduces Phoenix and helps the person try it out. The staff member also helps the person set real-world goals and between-session tasks to improve confidence, and reviews progress. Patients can keep the headset for six weeks in order to use Phoenix on their own. Phoenix has three main therapeutic areas within VR for the user: creating a sense of achievement and mastery to develop the belief ‘I can make a difference’; succeeding in challenging situations to develop the belief ‘I can do this’; and engaging in pleasurable activities to develop the belief ‘I can enjoy things’. The achievement and mastery scenario is set in a community garden, with ten tasks relating to the care of plants, animals, and a farmhouse. The challenging situation is a TV studio, with the user having to speak to the camera in front of an audience. There are ten levels of difficulty. The pleasurable experiences are set near a lake by a forest and tasks include relaxation exercises and games. A virtual coach (called Farah) guides the participant in the best way to think, feel, and respond. Patients choose which VR scenarios they wish to complete, and can repeat activities as often as they would like. The sessions can take place at home, in the clinic, or in a psychiatric ward.
