Mindfulness Based Cognitive Therapy (MBCT) is a psychological therapy which blends mindfulness techniques with features of cognitive therapy.
It was founded by Zindel Segal, Mark Williams and John Teasdale of University of Oxford Dept. of Psychiatry, Warneford Hospital, Oxford, UK.
The Basis and Purpose Of Mindfulness Based Cognitive Behaviour Therapy
Learning how to step out of automatic reactions to thoughts and feelings
The purpose of MBCT is to develop a "freedom from the tendency to get drawn into automatic reactions to thoughts, feelings, and events".
It involves accepting thoughts and feelings without judgement rather than trying to push them out of consciousness, with a goal of correcting cognitive distortions.
The basis of MBCT
"Mindfulness-based cognitive therapy (MBCT) is an approach to psychotherapy that uses cognitive behavioral therapy (CBT) methods in collaboration with mindfulness meditative practices and similar psychological strategies.
It was originally created to be a relapse-prevention treatment for individuals with major depressive disorder (MDD)." Source - Wikipedia
When we are vulnerable to depression, we lose touch with what is going on around us, and tend to develop tunnel vision. Very specifically and critically - we do not notice the moment when a spiral of low mood is starting.
Mindfulness practice helps us to see more clearly the patterns of the mind; and to learn how recognise when our mood is beginning to go down. This means we can ‘nip it in the bud’ much earlier than before.
Mindfulness practise teaches us a way in which we can get back in touch with the experience of being alive.
Shifting mental gears and halting the escalation of negative thoughts
Mindfulness helps to halt the escalation of negative thoughts and teaches us to focus on the present moment, rather than reliving the past or pre-living the future.
Mindfulness
teaches us to shift our "mental gears, from the mode of mind dominated by critical thinking (likely to provoke and accelerate downward mood spirals) to another mode of mind in which we experience the world directly, non-conceptually, and non-judgementally.
What Matters Is Not The Content Of Your Thoughts But Your Relationship With Your Thoughts
In dealing with our thoughts, I have found that there are four stages: awareness of our thoughts; understanding our thoughts; accepting our thoughts; and, living with our thoughts.
