We owe thanks to several peo- ple. Mike Gara provided theoretical and methodological guidance, sound practical judgment, and occasional flashes of brilliance. Paul Lehrer was there at the beginning with his unsurpassed scholarship and estimable clinical wisdom. Javier Escobar’s enlightened adminis- trative leadership and impeccable intellectual sensibilities were indis- pensable to the project. Jim Nageotte of The Guilford Press provided the optimal combination of encouragement and oversight. Thanks also to Seymour Weingarten for being everything a publisher should be. We owe our deepest gratitude, however, to the many patients and trainees who have labored along with us to alleviate the form of suffering that this book addresses.

In somatization physical symptoms occur in the absence of any identifiable causal mechanism. The causes of somatization that we are able to implicate are neither proximate nor somatic, seeming instead to be indirect and to reside in the patient’s mind or culture. Somatization appears to be universal. We find it in all present societies and in all past societies for which we have relevant records. Forty centuries ago, the physicians of Egypt were familiar with somatization; some years later so were those of ancient Greece. For the contemporary clinician, the patient who somatizes is a pressing practical problem. Here there is distress, dysfunction, and dis- ability of great magnitude and intransigence. Patients diagnosed with the most severe form of somatization, somatization disorder, have been shown to incur healthcare expenses that are nine times the U.S. average and consume disproportionate amounts of the time and energy of healthcare providers (Smith, Monson, & Ray, 1986a). In addi- tion to the extensive direct costs, somatization disorder creates enor- mous indirect costs to the economy in the form of lost work productiv- ity. Individuals diagnosed with somatization disorder report being bedridden for 2–7 days per month (Katon et al., 1991; Smith et al., 1986a). Somatization disorder is not only costly, but also difficult to treat successfully. In a longitudinal study following patients with somatization disorder who were receiving standard medical care, only 31% recovered after 15 years (Coryell & Norten, 1981). Typically, patients with somatization disorder are dissatisfied with the medical services they receive and repeatedly change physicians (Lin et al., 1 2 TREATING SOMATIZATION 1991). These “treatment-resistant” patients frustrate healthcare providers with their frequent complaints and dissatisfaction with treatment (Lin et al., 1991). No controlled medication trial for somatization disorder has been published. Anecdotal evidence suggests that many patients diagnosed with somatization disorder refuse to take medication and that those who do frequently report adverse medication side effects (Murphy, 1982). The story is much the same with other poly- symptomatic somatoform disorders (Fallon, 2004). As of this writing, pharmacological treatment has had minimal success with somatization. In this book we describe our efforts to alleviate the suffering of patients with somatization. Over the last decade, we have developed a dedicated psychosocial treatment for somatization that draws upon various traditions in psychotherapy, especially cognitive-behavioral therapy and emotion-focused experiential therapies, a treatment we call affective cognitive-behavioral therapy (ACBT). The principal aim of this book is to describe that treatment and to provide the training material necessary for its effective use. To frame our approach to this problem, we first provide a brief review of the history of somatization and of psychosomatic medicine. We then discuss philosophical and sociocultural underpinnings of somatization and conclude with an overview of theories of somatization. BACKGROUND: HISTORICAL AND THEORETICAL The history of somatization begins with hysteria. Hysteria was first described 4,000 years ago by the Egyptians. Typical cases involved pain in the absence of any injury or pathology in the location of the pain. The Egyptian theory held that a wandering uterus moved about the body and produced pain from various regions. Greek physicians described a similar set of psychosomatic symptoms and essentially retained the Egyptian theory. The Greeks gave us the word hysteria, from the Greek hystera, meaning womb. The Greco-Egyptian formula- tion reveals two noteworthy features: that the disorder was primarily observed in females and that there was something thought to be essentially female about the disorder. Although the diagnostic category sub- sumed more than somatization, the term hysteria continued to be widely used to label somatization patients until 30 years ago. Medieval and Renaissance medicine preserved the ancient formu- lation of hysteria as described by the ultimate authorities, Hippocrates and Galen, until the 17th and 18th centuries, when it was first linked with the
