The treatment section starts with Marangell, Silver, and Yudofsky’s comprehensive chapter "Psychopharmacology and Electroconvulsive Therapy," which gives readers the principles of drug action, including mechanisms of action, indications and contraindications for use, and recommendations about the selection of medications for specific conditions. The next two chapters, "Brief Dynamic Individual Psychotherapy" and "Psychoanalysis, Psychoanalytic Psychotherapy, and Supportive Psychotherapy," merit special comment. In our current managed health care era, in which many for-profit companies provide insurance coverage for only 10 psychotherapy sessions, it has become necessary, if not mandatory, for psychiatrists to become expert in the use of brief psychotherapies. This chapter presents specific guidelines, illustrated by tables and outlines of key points, that supply students and residents with the fundamentals of brief therapy. The ensuing chapter complements the presentation of brief dynamic psychotherapy by supplying the psychodynamic background for it and by discussing interpersonal psychotherapy briefly. Moreover, it presents the basic principles and practice of supportive psychotherapy by explicitly defining and listing goals and techniques along with characteristics of the types of patients for which it is indicated. Those two chapters will be especially valuable for students, residents, and even experienced practitioners, who too often consider supportive psychotherapy to consist mainly of somewhat nebulous "reassurance."
