The specialist mood disorders team will include a psychiatrist and health professionals providing cognitive behaviour therapy. Together the team will assess participants and then provide a co-ordinated and supervised combination of pharmacological and psychological treatment according to guidelines developed by NICE and the British Association of Psychopharmacology. Each participant will receive a treatment plan that is tailored to his/her specific needs. The participants in the treatment as usual team will have their usual access to the same treatments. The outcome in terms of improvement in depressive symptoms, function and costs will be examined after one year in service users with chronic depression.
