DSM-IV-TR recognizes five major somatoform disorders: somatization disorder, conversion disorder,

hypochondriasis, body dysmorphic disorder, and pain disorder. Somatoform disorders should be differentiated from malingering, in which the essential feature is the intentional production of false or grossly exaggerated physical or psychological symptoms motivated by external incentives such as avoiding work, obtaining financial compensation, evading criminal prosecution, or obtaining drugs. The first four somatoform disorders are discussed in the following subsections; pediatric pain disorders are discussed in Chapter 9.

In the International Statistical Classification of Disease and Related Health Problems, 10th Revision (ICD-10), the World Health Organization (2006) defines the main features of somatoform disorders as "the repeated presentation of physical symptoms together with persistent requests for medical investigations, in spite of repeated negative findings and reassurances by doctors that the symptoms have no physical basis. If any physical disorders are present, they do not explain the nature and extent of the symptoms or the distress and preoccupation of the patient" (Chapter V, F45). The ICD-10 includes somatiza-tion disorder, undifferentiated somatoform disorder, hypochondriacal disorder, persistent somatoform pain disorder, and other somatoform pain disorder, all of which correlate with their DSM-IV-TR counterparts. The ICD-10 differs from DSM-IV-TR by also including somatoform autonomic dysfunction and by excluding body dysmorphic disorder, which has been hypothesized to have features more in common with obsessive-compulsive disorder.
