John Teasdale

Explained how mindfulness blocks depression relapse.

Co-developer of MBCT whose theory showed that changing one’s relationship to thoughts — not their content — prevents relapse.

In mindfulness we pay attention to experience rather than being lost in it.
— John Teasdale

Who they were

John Teasdale is a British clinical psychologist and former research scientist at the MRC Cognition and Brain Sciences Unit in Cambridge. He is one of three co-founders of MBCT. His work on metacognitive awareness and decentering explained why observing thoughts as passing mental events, rather than facts, reduces depressive relapse. He is a Fellow of the British Academy.

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.
