Genetic Links to Anxiety and Depression (GLAD)

Depression and anxiety are common but complex disorders, whose research needs very large sample sizes. The Genetic Links to Anxiety and Depression (GLAD) study aims to recruit >40,000 individuals. Anyone 16 or older who has experienced anxiety or depression during their lives can join this recontactable database to facilitate future research.

How can I take part?
All enrollment takes place online at our website (see below). An online animation explains the consent process with more detailed information in text format. Once you have provided consent and completed an online questionnaire you will be sent a saliva DNA sample kit to enable genetic studies.

We really hope you will join us in this important endeavour!


We are looking for:

participants who must:

  • Have experienced clinical anxiety and/or depression at some time during their life
  • Be aged 16 and above
  • Live in England


  • Online/home-based
  • East of England
  • East Midlands
  • London
  • North East & Cumbria
  • North West
  • South East
  • South West
  • West Midlands
  • Yorkshire & the Humber


Whilst you will not receive any payment for taking part in the GLAD Study, your contribution to the project will help future discoveries in mental health research and could potentially lead to a medical breakthrough in how we treat depression and anxiety.
