It is interesting that while virtually all of the contributors note the difficulties in treating personality disorders, almost all maintain a positive attitude about what is possible. Only Stone, reminiscing on his close to 45 years of experience, illustrates precisely the extreme hardships of trying to treat patients with personality disorders, which include their high discontinuation rate, alarming sensitivity to affront, and the ease with which discontinuation can be precipitated. He classifies patients in the personality disorders group (and others) in terms of their being inhibited or not inhibited. Patients in the inhibited groups (e.g., obsessive-compulsive, avoidant, or dependent personalities) and patients with phobias or sexual inhibitions suffer from their symptoms and are therefore motivated to change. Patients in the noninhibited groups (narcissistic and psychopathic disorders) find their symptoms ego-syntonic. Thus, they are dismissive, self-centered, and impulsive and are concerned with others, if at all, only with extracting quickly what they want. Obviously, they are less likely to be amenable to psychotherapy. Stone's view on prognosis, generally, is also less sanguine (and perhaps more realistic) than those of the other contributors.
