Welcome to Sleepsight

People living with psychosis often experience problems with their sleep, particularly when symptoms worsen.

Sleepsight is an innovative research study taking place in South London which uses wearable and mobile technologies to study the links between sleep, activity and symptom levels in psychosis. 


Activity tracker

Participants are given a modern activity tracker to wear on their wrist, day and night, for the duration of the study.

The watch measures activity levels and sleep, and sends data to a smartphone using wireless technology.

The watch is water proof, and does not need charging.


We provide participants with a Motorola android smartphone, and a mobile contract, at no cost to the participant.

Once a day, participants are asked to complete a short questionnaire on the smartphone, taking no more than 2 minutes to complete, asking about sleep and symptom levels.

We ask that the smartphone we provide is used as their main phone – including making calls, sending messages, and browsing the internet.


We ask participants to take part in the study for up to 12 months.

Participants will be compensated for their time and effort at the end of the study.

The research should help us to understand how changes in sleep pattern relate to changes in wellbeing.

Sleepsight is funded by the Medical Research Council, and has received ethical approval from the London Dulwich Research Ethics Committee.

We are looking for participants who:


•  Have a psychosis diagnosis (including schizophrenia and schizoaffective disorder)

•  Are aged between 18-65

•  Are under the care of the South London and Maudsley NHS Foundation Trust

•  Are able and interested in using the study technology for 12 months


If you’re interested in participating, or are working with a service user who is, please contact us below.
