— Mark Williams

Who they were

J. Mark G. Williams is a British clinical psychologist and Emeritus Professor of Clinical Psychology at the University of Oxford. He is one of three co-founders of MBCT and was founding director of the Oxford Mindfulness Centre. His research focuses on preventing depression and suicide, especially the cognitive processes that make relapse likely.

Their big idea

Mindfulness-Based Cognitive Theory

Depression relapses when low mood reactivates old thought patterns; mindfulness changes that relationship.

The approach they founded

Mindfulness-Based Cognitive Therapy

Blends cognitive therapy with mindfulness so you relate to thoughts and moods differently — and stop the relapse spiral.
