Remote Assessment of Depression and Relapse - Major Depressive Disorder (RADAR-MDD)

RADAR-MDD aims to use wearable technology, such as smartphone sensors and fitness trackers, to measure symptoms of major depressive disorder and predict future relapse. We are recruiting people who have recently experienced depression to participate. Participants will be given a FitBit and asked to download some apps onto their smartphone: some apps will be used to collect information from sensors which are already in most modern smarpthone; other apps will be used for participants to answer questionnaires about their mood and social environment, or complete some cognitive tasks. For a maximum of 2-years, this data will provide insight into changes in physical activity, sleep, stress, mood, sociability, speech and cognitive function, which may be associated with future depressive relapse. 


We are looking for:


To be eligible, people should have:

  • experienced depression (at least twice during their lifetime, with at least one episode within the last 2 years);
  • no previous diagnosis of bipolar disorder, psychosis, schizoaffective disorder or emotionally unstable personality disorder;
  • an android smarpthone, or be willing to switch to android as their main phone for the duration of the study.

People currently experiencing symptoms as well as those who are currently in remission are welcome.
