Review: collaborative care improves depression and anxiety symptoms in adults
Question: How effective is collaborative care for anxiety and depression?
Outcomes: Changes in depression or anxiety assessed by self-reported or clinician-rated instruments. Outcomes were classified as short-term (0–6 months), medium term (7–12 months), long term (13–24 months) and very long term (25 months or longer).
