To the outsider, behavioral therapy seems almost intuitive. Its basic principle, which is reiterated throughout the book, is “just do it.” The idea is simple; if you get up, get active, and do the things you're avoiding, you'll feel better. However, people with ties to the patient have probably already given this advice, so how does a therapist help facilitate this change? Most practitioners have recommended, for example, that patients exercise or reconnect with old friends—with little result. The answer, it seems, is to help the patient formally schedule activities and then work together to overcome obstacles. It is important as well to assign homework, as is done in cognitive-behavioral therapy, because the patient can frequently get off track if he or she is not closely monitored. This approach is in the trend of the research in the field, and this book is certainly a useful addition to the field of knowledge.
