This chapter on Intrusive obsessional thoughts was part of the second edition of “Understanding Panic Attacks and Overcoming Fear” by Roger Baker, published by Lion- Hudson publishing company in 2003. It was not included in the third edition of the book which came out in 2011 so it’s good to be able to have it available, with permission from Lion-Hudson.”
Another free chapters are Emotional processing and preventing of panic and Emotional Processing Therapy in overcoming post traumatic stress.
