If you're looking for resources to learn ACT, you should take a look at 'The Happiness Trap', published in the USA by Shambhala. 'The Happiness Trap' is unique amongst ACT books in that it is the only one that has been written for EVERYONE - therapists, coaches, housewives and astronauts, no matter what their life circumstances, and regardless of whether or not they have ‘mental health issues’ - which also explains ACT in a simple, easy-to-understand manner, without any technical language, or a battery of worksheets and inventories. It is increasingly used as a resource by both therapists and coaches - not only to use with their clients, but also as a way of learning the theory and techniques of ACT in a simple, clear and entertaining manner. And its ultra-low cost also helps: only $10.50 via www.amazon.com
