" Learning how to do psychotherapy is a complex process, much of which is transacted in the relationship between the beginning therapists and experienced supervisors. When the beginning therapists encounter problems that are beyond their range of experience, the supervisors usually assist in several ways. First, the supervisors offer an intellectual
framework in which to understand the problem. References to the professional literature are often suggested. Second, the supervisors offer practical, problem-solving help with the strategies of therapy. Third and most important, the supervisors help the less experienced therapists to deal with feelings of their own that have been evoked by the patients. With the support of competent supervisors, the therapists are usually able to master their own troubled feelings and put them in perspective.
This done, the therapists are better able to attend to patients with empathy, and with a confidence in their ability to offer help. "
