Diagnosis, Management and Outcomes of Depression in the Primary Care Setting (The Diamond 10-year Cohort Study)

Project Details

The Diagnosis, Management and Outcomes of Depression in Primary Care Study (Diamond cohort Study) is a unique resource of 10 years of data collected from 789 people in the primary care setting.  The study was established in 2005 to explore the course and management of depression in the primary care setting in recognition that most treatment and management of common mental disorders occurs in general practice.  Diamond is now one of the largest and longest running cohorts of its kind globally. Study participants complete annual written surveys and telephone interviews about their symptoms, diagnosis, treatments, medications, health service use, comorbidity, physical health, substance use, the experience of depression and recovery.

To date, 24 students have completed research theses using Diamond data ranging on topics from GP consultation length and depression care outcomes to social connectedness and its association with depression. The study has hosted nine international postdoctoral fellows conducting research into areas such as long-term antidepressant use, the association between physical disease and mental health multi-morbidity and self-rated health, and exploring interventions for depression care that allocates treatment based on individual risk for persistent depressive symptoms.

This research is one of the most comprehensive data sets of its type in the world, and forms the basis of much productive international collaboration. Some 28 peer reviewed journal articles have been published as well as ten book chapters.
