Recent findings Most experts on medically unexplained symptoms agree that there is a substantial need for revision of the diagnoses of somatoform disorders. While some authors suggest moving the somatoform disorders from axis I to axis III, others suggest improving the classification of these syndromes on axis I, such as by using empirically derived criteria and by introducing psychological descriptors which justify the categorization as a mental disorder. In contrast to the situation when the last version of Diagnostic and statistical manual for mental disorders was published, new empirical data has shown some psychological and behavioural characteristics of patients with somatoform symptoms. These and other empirically founded approaches can be landmarks for the revision of this section in Diagnostic and statistical manual for mental disorders-V and International classification of diseases-11. Summary The classification of somatoform disorders as ‘mental disorders’ could be justified if empirically founded psychological and behavioural characteristics are included into the classification process. Attention focusing, symptom catastrophizing, and symptom expectation are outlined as possible examples of involved psychological processes. © 2007 Lippincott Williams & Wilkins, Inc.
