I would say that CBT is one of the best ways of actually getting out of the LGAT mindset.
Of course, CBT can be abused, and distorted, and I am sure people are doing it.
But proper CBT is the exact opposite of the LGAT, in that its about critical thinking, and testing your beliefs, being realistic, flexible, non-manic, etc.
David Burns, in my view, is legit.
The Feeling Good Workbook is even clearer, in my view.
A terrific, and simple CBT book is "Mind Over Mood".
For the technical minded, Dr. Aaron Beck, who is the founder of that school of CBT, has written many books. That gives the foundation, and the foundation is based on actual scientific based testing.
but I would suggest that a person finds a highly trained CBT therapist, referred from the Beck Institute, and learns how to do CBT step by step, one-on-one, if possible. [www.beckinstitute.org
I seem to recall there was a thread in the Recovery section about CBT? anyone remember that, or know where it is?
