This unique book is the first to bring together the world of health psychology with that of complementary and alternative medicine (CAM). The authors draw on their wealth of experience as health psychologists to explore the relationship between health psychology and CAM and look at how an understanding of one can be used to inform the other. Through an open-minded but rigorous approach to CAM, the authors identify where psychology can help to answer some crucial questions, such as why CAM sometimes appears to work, why sometimes it does not, and why some people are drawn to it and others not.
