This is a terrible book. There are so many great books that help physicians understand patients but this is not one of them. The authors have a very bad attitude about the patients and are basically advocating that physicians be very suspicious, assume they are malingering, or just want attention, or have some other psychological reason for seeking medical help.
I understand that physicians do have to recognize that patients have psychological factors involved but this book gives the impression that psych factors are usually prominent. They do not help physicians figure out how to identify the patients who are at particular risk of having prominent psychological factors, they seem to imply that all patients are like that...
