About the Study

The Genetic Links to Anxiety and Depression (GLAD) Study, led by the National Institute for Health and Care Research (NIHR) Mental Health BioResource and researchers at King’s College London, in collaboration with researchers at Queen's University Belfast, University of Edinburgh, and Cardiff University, is a project set up to support studies exploring risk factors for depression and/or anxiety.

Depression and anxiety are the most common mental health disorders worldwide. In the UK, 1 in 3 people will experience symptoms during their lifetime. The GLAD Study aims to better understand depression and anxiety in order to find effective treatments and improve the lives of people experiencing these disorders.

We are pleased to announce that we have now extended recruitment to Wales, Scotland and Northern Ireland!
We thank you for taking part and joining the largest ever study of depression and anxiety!
