Criteria Used for the Diagnosis of Fibromyalgia Syndrome (FMS)
| Widespread Pain Index (WPI) (19 pts possible) |
| Subjects were asked to shade areas on a diagram of the human body to indicate where they felt pain. The areas of overlap between those and the 19 areas designated by the ACR to reflect widespread pain consistent with FMS were counted. |
| Somatic Symptom Severity (SS) Scores Total (12 pts possible) |
| Fatigue, waking unrefreshed and cognitive symptoms were each evaluated individually for symptom severity from 0 (no problem) to 3 (severe, pervasive, continuous, life-disturbing problem). This information was elicited by specific questions embedded in the instruments listed below. A positive response in the PDSQ1, a score of 2 or 3 on the Pittsburgh sleep index2, a score of 3 or 4 in the POMS questionnaire3, and a score of 5 or greater in the VAS4 were interpreted as somatic symptoms consistent with FMS. The final category of Symptoms in General describes symptom severity of a wide variety of disorders detected by the instruments described as well as the patient’s medical history. |
| Fatigue Score (3 pts) |
| POMS 3 Have you felt worn out during the past week? |
| POMS 13 Have you felt fatigued during the past week? |
| POMS 19 Have you felt exhausted during the past week? |
| Waking Unrefreshed (3 pts) |
| Pittsburgh sleep #6: During the past month, how would you rate your sleep quality overall |
| PDSQ 10: Did you feel tired out nearly every day during the past 2 weeks? |
| Cognitive Symptoms (3 pts) |
| PDSQ 14: Did you have problems concentrating nearly every day during the past 2 weeks? |
| PDSQ 15: Was decision making more difficult than normal during the past 2 weeks? |
| POMS 29: Did you feel forgetful during the past week? |
| Symptoms in General (3 pts) |
| VAS (5 or greater of 1–10) |
| PDSQ 102: GI problems |
| PDSQ 103: Diffuse aches |
| PDSQ 1: Sad or depressed |
| POMS 7: Sad (if 3 or 4) |
| POMS 1: Tense (if 3 or 4) |
| POMS 16: Nervous (if 3 or 4) |
1
The Psychiatric Diagnostic Screening Questionnaire (PDSQ) raw scores were Yes or No answers.
2
The Pittsburgh Sleep Quality Index (PSI) was scored from 0 = very good to 3 = very bad).
3
The Profile of Mood States-Short Form (POMS) questionnaire has raw scores from 0 to 4.
4
The visual analog scale (VAS) was scored from 0 to 10 for pain intensity.
