Fibromyalgia Prevalence, Somatic Symptom Reporting, and the Dimensionality of Polysymptomatic Distress: Results From a Survey of the General Population

The modified 2010 diagnostic criteria do not result in high levels of fibromyalgia. PSD and fibromyalgia are strongly related to somatic symptom severity. There is evidence in support of fibromyalgia as a dimensional or continuum disorder. This has important ramifications for neurobiologic and epidemiology research, and for clinical diagnosis, treatment, and ascertainment of disability.
