Chronic widespread pain is the cardinal clinical feature of the fibromyalgia syndrome, which, in the majority of clinic patients, is persistent. By contrast, in community-derived patients, pain is persistent in only half of the affected individuals, particularly those with psychological distress. Whether such distress is a consequence of the pain or a manifestation of a wider process of somatization which is associated with the persistence of pain is unclear. ⋯ Although almost half of the cases of chronic widespread pain resolved within 1 yr, this study has demonstrated for the first time that those subjects who display features of somatization are more likely to have widespread pain which persists. These findings have implications for the identification and treatment of persons with persistent chronic widespread pain.
