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.
Sleepsight was funded by the Medical Research Council, and received ethical approval from the London Dulwich Research Ethics Committee.
Participants were given a modern activity tracker to wear on their wrist, day and night, for the duration of the study.
The watch measured activity levels and sleep, and sends data to a smartphone using wireless technology.
We provided participants with a Motorola android smartphone, and a mobile contract, at no cost to the participant.
Once a day, participants completed a short questionnaire on the smartphone.
We asked participants to take part in the study for up to 12 months.
We looked for participants who:
- Had a psychosis diagnosis (including schizophrenia and schizoaffective disorder)
- Were aged between 18-65
- Were under the care of the South London and Maudsley NHS Foundation Trust
- Were able and interested in using the study technology for 12 months
