| - | ====== Widespread Pain Index (WPI) ====== | ||
| - | The [[https://www.medscape.com/answers/329838-18859/what-is-the-widespread-pain-index-wpi-in-the-diagnostic-criteria-for-fibromyalgia|Widespread Pain Index]] quantifies the extent of bodily pain on a 0-19 scale by asking [[start|Lifelines]] participants if they have had pain or tenderness in 19 different body regions over the past week, with each painful or tender region scoring 1 point ([[sections|section]]: [[Diseases & symptoms]]).\\ | ||
| - | Note that pain was also assessed in Lifelines participants as a symptom of several specified medical conditions, for example [[musculoskeletal symptoms|here]]. | ||
| - | |||
| - | ===== Background ===== | ||
| - | |||
| - | The WPI originated as a part of the Fibromyalgia Survey Questionnaire (FSQ) that sets diagnostic criteria for [[https://en.wikipedia.org/wiki/Fibromyalgia|fibromyalgia]]. The full FSQ also contains a symptom severity score (SSS) for the following symptoms: fatigue, waking unrefreshed, cognitive symptoms and somatic symptoms ((Wolfe F. et al. (2011) Fibromyalgia criteria and severity scales for clinical and epidemiological studies: a modification of the ACR Preliminary Diagnostic Criteria for Fibromyalgia. Journal of Rheumatology 38(6): 1113–1122)). In Lifelines, this information can be derived from other variables (i.e. [[fatigue (general)]], [[symptoms (SCL-90)]], and various [[mental health|cognition]]-related variables).\\ | ||
| - | This instrument is required for the diagnosis of fibromyalgia in epidemiological studies. At [[musculoskeletal conditions|baseline]], the presence of fibromyalgia was assessed by self-report (i.e. asking participants whether they suffer from fibromyalgia), but recent studies indicate that this methodology misses 77% of the fibromyalgia diagnoses ((Warren JW, Clauw DJ (2012). Functional somatic syndromes: sensitivities and specificities of self-reports of physician diagnosis. Psychosomatic Medicine 74(9):891-895)). Implementation of the WPI improves the identification of participants that meet the diagnostic criteria of fibromyalgia. | ||
| - | |||
| - | ===== Validity ===== | ||
| - | A recent German study showed that the reliability, convergent and discriminant validity of the FSQ were good, however, the The WPI was not evaluated separately((Häuser W. et al. (2012). Validation of the Fibromyalgia Survey Questionnaire within a cross-sectional survey. PLoS One 7(5):e37504)). | ||
