In DSM-IV, the relationships between physical illness and psychological factors are grouped under the classifications 'Somatoform Disorders' and 'Psychological Factors Affecting Medical Conditions'(PFAMC). This volume introduces the 'Diagnostic Criteria for Psychosomatic Research' (DCPR) as a new proposal for the PFAMC section of DSM-V. The DCPR approach focuses on psychological characteristics of patients presenting symptoms across different medical disorders related to the clinically relevant psychosocial constructs of abnormal illness behavior, i.e. somatization, demoralization, type A behavior, alexithymia, conversion, and irritability. The distinct DCPR categories are consistent with concepts expressed by outstanding authors in psychosomatic medicine and are therefore suggested as specifiers of PFAMC for the future DSM-V. The volume includes updates, reviews and empirical findings on psychological factors affecting various disorders in different clinical settings (endocrinology, gastroenterology, oncology, dermatology, eating disorders, consultation psychiatry). It is essential reading for psychiatrists, psychologists and physicians interested in psychosomatic medicine, and provides the basic tools for the diagnosis of DCPR conditions.
