The diamond cohort study - long term outcomes of depressive symptoms in primary care
Grant number: 566511 | Funding period: 2009 - 2011
The diamond study follows what happens to almost 800 people with depressive symptoms whom attend general practice for care over 5 years of their life. This study will map the severity of depressive symptoms, life circumstances, use of health care services and treatments and allow us to understand factors associated with relapse and recovery from depression in order to improve care. This will assist us to develop models of care that better suit the needs of people experiencing depressive symptoms.
