Recruited 424 patients with a history of 3+ depressive episodes. All were taking anti-depressant medication. Half the group were randomly assigned to an 8 week course of MBCT, during which they were also given given help to come off medication. The other half continued their anti-depressants for 2 years. Mindfulness did not prove to be superior to anti-depressants. The relapse rate for both groups was similar.
