Widespread Pain Index (WPI)

The Widespread Pain Index quantifies the extent of bodily pain on a 0-19 scale by asking 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 (section: Diseases & symptoms).
Note that pain was also assessed in Lifelines participants as a symptom of several specified medical conditions.

Background

The WPI originated as a part of the Fibromylagia Survey Questionnaire (FSQ) that sets diagnostic criteria for fibromyalgia. The full FSQ also contains a symptom severity score (SSS) for the following symptoms: fatigue, waking unrefreshed, cognitive symptoms and somatic symptoms 1). In Lifelines, this information can be derived from other variables (i.e. fatigue (general), Symtoms (SCL90), and various cognition-related variables).
This instrument is required for the diagnosis of fibromyalgia in epidemiological studies. Scoring above a cut-off on this scale is one of the three diagnostic criteria for fibromyalgia. Including it in the Lifelines screening will add to a new diagnosis in the Lifelines dataset. The presence of fibromyalgia is currently only questioned by self-report, but recent studies indicate that this methodology misses 77% of the fibromyalgia diagnoses 2).

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 separately3).

Het valt me op dat als ik op fibromyalgie zoek, ik niet op deze pagina kom. Ik snap hoe dat komt: de Nederlandse term komt er niet op voor. Misschien zou het handig zijn om het zoeksysteem aan te passen zodat Nederlandse termen ook werken, of de Nederlandse term te vermelden. Want je komt er wel mee op andere pagina's, dus dat wekt de indruk dat we alleen self-report diagnoses hebben.

  • Background: Fibromylagia → Fibromyalgia
  • Deze vragenlijst is afgenomen voor de diagnostische criteria van FM, en de andere criteria die nodig zijn kunnen uit andere vragenljsten worden afgeleid zoals vermeld. Toch staat hier “The presence of fibromyalgia is currently only questioned by self-report, but recent studies indicate that this methodology misses 77% of the fibromyalgia diagnoses”. Dat is verwarrend. De diagnose fibromyalgia is vanaf baseline al uitgevraagd via self-report in de vragenlijst, en daarnaast zijn de diagnostische criteria vanaf FUP4 opgenomen. Ik zou deze zinnen ook uit de beschrijving weghalen: “Scoring above a cut-off on this scale is one of the three diagnostic criteria for fibromyalgia. Including it in the Lifelines screening will add to a new diagnosis in the Lifelines dataset.”

  • Verbeterd (ook de link met SCL-90)
  • Zelfde als bij de CDC dus. Ik pas het aan.
