"Self-determination theory is grounded in the belief that people work best and are happiest when they feel that they are in control of their own lives. This invaluable book explains the ramifications of the theory and provides clinical examples to show that it can be used to motivate patients undergoing treatment for such physical or psychological issues as diabetes management, smoking cessation, post-traumatic stress, obsessive-compulsive disorder, and depression."--BOOK JACKET.
