somatic symptom disorder
in DSM–5, a disorder characterized by one or more significant bodily symptoms (e.g., pain) that cause distress or impair daily function and by excessive, maladaptive thoughts (preoccupation) or excessive worry about the symptoms, with or without the presence of a medical condition to account for the symptoms. One of two replacement diagnoses for hypochondriasis, somatic symptom disorder is determined based only on this set of criteria and does not also apply to high health anxiety that occurs in the absence of significant somatic symptoms, as in illness anxiety disorder. Somatic symptom disorder also replaces such DSM–IV–TR diagnoses as somatization disorder, requiring only one or two symptoms for diagnosis rather than the much higher symptom count (4 pain, 2 gastrointestinal, 1 sexual, 1 psychoneurological) of the older criteria.
