Cognitive Therapy was originally developed as a treatment for depression, and the emphasis was on shifting "distorted thinking" to "realistic thinking." As a support for this shift, Beck worked with his clients to identify thought distortions.
These included such things as:
Mind-reading: I’m sure they don’t like me.
Fortune Telling: The future wil be as bad as the past.
All-or-nothing thinking: If I don’t do a perfect job on this, I’m a failure.
Personalization: It’s my fault. I’m completely to blame.
1. I’m a failure.
2. I’m worthless.
3. I’m hopeless.
Therapy focuses on replacing these core negative beliefs with positive and realistic beliefs.
