History of CBT
Cognitive Behaviour Therapy was developed in the 1950's by Albert Ellis a psychotherapist. Ellis developed 'Rational Emotive Behaviour Therapy' (REBT) as a way to understand and overcome emotional disturbance. According to Ellis's theory people not only get upset by problems, but also form strong views about reality in relation to their perceived beliefs of that problem. If these beliefs are irrational or self-defeating, the result can be unhealthy to their emotional and behavioural function.
Aaron Beck an American Psychiatrist further developed Ellis' work in the 1960's. Beck created the term Cognitive Behaviour Therapy (CBT). According to Beck patients suffering with depression magnified negative thoughts and minimised positive ones. Thus, Becks' CBT aimed to alter this distorted way of thinking to change a patient's emotional and behavioural state.
