Practicing mental health clinicians can find a lot here, though the quality varies. For example, I found the section on psychological testing particularly worthwhile. The last section of the book, having to do with disorders often considered part of the obsessive-compulsive spectrum, such as impulse control disorders, tic disorders, and eating disorders, is a very sensible approach to what is still a gray area. Other strong chapters include those on psychological approaches to understanding obsessional problems, personality and obsessive-compulsive disorder, and assessment. The area of psychotropic medications is well handled. The best of the book's sections are clear; the worst can be hard to get through.
