REST: Relapse Evaluation using Smartphone Technology



REST (Relapse Evaluation using Smartphone Technology) is a new research study looking at whether or not it is possible for smartphone technology to detect and predict relapse in people suffering from a serious mental illness (SMI).

We are trialling a new smartphone app that could potentially help people with SMI get better help and timely support before they reach a crisis point, while also helping clinicians to provide better care.

Participants are recruited from several NHS sites in England, in a collaboration that includes University College London and Mindstrong Health. This study was reviewed and approved by the London - Dulwich Research Ethics Committee (IRAS study ID: 245218)

The smartphone app being tested is called Discovery and it was developed by Mindstrong Health, an American healthcare innovation company. The app uses digital phenotyping to better understand how human-computer interactions patterns can function as a continuous measure of brain function.


The app will passively collect metadata (e.g., swipes, taps, relative location, and timestamps of ingoing/outgoing calls or text messages) for a year. Participants will complete short monthly assessments of memory and cognition via the app, plus a telephone assessment of relapse indicators (e.g., hospitalisation, medication non-compliance). 

Relapse events are also assessed from objective clinical data collected from different NHS sites over the follow-up period. Smartphone metadata will be used to construct digital phenotypes (biomarker patterns) to predict relapse events.
