Criteria

A patient satisfies diagnostic criteria for fibromyalgia if the following 3 conditions are met:

  1. Widespread pain index (WPI) ≥7 and symptom severity (SS) scale score ≥5 or WPI 3 - 6 and SS scale score ≥9.
  2. Symptoms have been present at a similar level for at least 3 months.
  3. The patient does not have a disorder that would otherwise explain the pain.

  2. SS scale score:
    Fatigue
    Waking unrefreshed
    Cognitive symptoms
    For the each of the 3 symptoms above, indicate the level of severity over the past week using the following scale:

    0 = no problem
    1 = slight or mild problems, generally mild or intermittent
    2 = moderate, considerable problems, often present and/or at a moderate level
    3 = severe: pervasive, continuous, life-disturbing problems

    Considering somatic symptoms in general, indicate whether the patient has:*

    0 = no symptoms
    1 = few symptoms
    2 = a moderate number of symptoms
    3 = a great deal of symptoms

The SS scale score is the sum of the severity of the 3 symptoms (fatigue, waking unrefreshed, cognitive symptoms) plus the extent (severity) of somatic symptoms in general. The final score is between 0 and 12.
