Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will receive 12 weekly one hour one-to-one sessions of a support intervention for hearing voices (auditory verbal hallucinations) from a peer mental health worker who has had personal lived experience of hearing voices themselves. The intervention will involve buidling a shared understanding of the participant's experience of hearing voices and using this to inform how to respond to hearing voices and cope with this experience more effectively. The intervention group will receive the intervention alongside treatment as usual (TAU) in the 3 month period immediately following randomisation, whilst the control group will receive the intervention after a 3 month TAU wait list period.

Summary
Brief summary
Hearing voices (auditory verbal hallucination) is a potentially distressing and disabling experience which often persists in spite of treatment with medication. This pilot study examines whether it is helpful for people who hear voices to receive assistance in coping with this experience from someone else who hears voices and has adapted to living with this experience.
