I would not recommend this book to any serious person wanting to know about cognitive therapy as it is no more than a definition and outline of the subject. Organization is poor with jumping around in short chapters, making for confusion. Sadly, pretty much a waste of time.
This book only scratches the surface about this topic. However, it provides some good tips for how to start working with CBT in order to change behavior. In the end of the day, it is a good cost-benefit book.
It is wonderful and gives specific approaches to solving behavioral problems. The author could have given some examples of actual case studies of people who used these techniques based on his experiences when he was developing these concepts.
