The category of interpersonal deficits is the most questionable theoretically and the most problematic therapeutically, as the author acknowledges. It encompasses patients who are isolated, have poor social skills, and lack connection with others. The author advises steering clear of this area, if possible, and choosing another focus with the patient. Many of the interpersonal therapy failures are with patients who have interpersonal deficits. The author emphasizes the need to try different approaches when failure occurs. He should have included the need to review the diagnosis. Unsuccessful outcomes are often caused by misdiagnosis. I suspect that in addition to having axis II features, as the author suggests, some patients with interpersonal deficits may have social phobia.
