COS-D
Deciding together what matters in depression care
COS-D brings people with depression, healthcare professionals, and informal caregivers together to agree on what should be measured in depression research and care.

What is COS-D?
COS-D — a Core Outcome Set for Depression — is a research study working out which outcomes should be measured in depression research and care: the things that actually change for someone. It draws on the experience of people with depression, the expertise of healthcare professionals, and the perspective of informal caregivers.
Why it matters
Studies and services don't always measure the same things, which makes it hard to compare results or know what really helps. Agreeing on a shared set of outcomes makes depression research and care easier to compare, combine, and improve — for everyone involved.
Who's involved
COS-D only works if it reflects everyone affected by depression — not just one point of view.
People with depression
Lived experience of depression, including what recovery and support feel like day to day.
Healthcare professionals
Clinical expertise from working with depression in practice, and what's realistic to measure.
Informal caregivers
The perspective of family and friends who support someone through depression.
