The Cochrane Common Mental Disorders Group is part of Cochrane, an international not-for-profit organisation dedicated to making up-to-date, accurate information about the effects of healthcare readily available worldwide. We work with authors from around the world to produce and disseminate systematic reviews of healthcare interventions for treating and preventing a range of mental health problems. Some of the conditions we cover are: depression, anxiety, eating disorders, somatoform disorders and suicide (for a full list, see Scope). Our reviews are published online on the Cochrane Library, where they are used by clinicians, researchers, healthcare consumers and international guideline developers to inform healthcare knowledge and decision making.
