Here is an interesting background profile on how cognitive behavioural therapy became established.
Cognitive Therapy, or Cognitive Behavior Therapy (CBT) was pioneered by Dr. Aaron T. Beck in the 1960s, while he was a psychiatrist at the University of Pennsylvania. He designed and carried out several experiments to test psychoanalytic concepts of depression. Fully expecting the research would validate these fundamental concepts, he was surprised to find the opposite.
As a result he began to look for other ways of conceptualizing depression. For instance, he found depressed patients experienced negative thoughts that seemed to arise spontaneously. He named these “automatic thoughts.” He found these automatic thoughts fell into three categories. They had negative ideas about themselves, the world and/or the future.
He began helping patients identify and evaluate these automatic thoughts, and as a result, patients were able to think more realistically. As a result, they felt better emotionally and were able to behave more functionally. Dr. Beck called this approach “cognitive therapy.” It has also become known as “cognitive behavior therapy.”
Tomatoe - Tomato, the use of grammar in Cognitive Behavioural Therapy/Cognitive Behavioral Therapy is well worth noting in a search for more information on the internet. The word 'Behavioural', spelt the English Dictionary way is spelt 'Behavior' in the USA, use of both can help those looking for more information on the subject.
