What this study is about
This study makes a new questionnaire about visual hallucinations and what people think about them.
It looks at links with sleep problems and worry.
What will happen
About 900 people with psychosis will complete a 30–45 minute questionnaire. Around 100 of them will answer some questions again a week later to check if answers stay the same. By developing a new measure and our knowledge of visions, it will be the next important steps to developing better treatments for visual hallucinations.
Who sponsors it
Cumbria, Northumberland, Tyne, and Wear NHS Foundation Trust.
Recruitment end date: 31 March 2026.
