| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
Fibromyalgia survey for epidemiologic and clinical studies based on the 2010 American College of Rheumatology Preliminary Diagnostic Criteria for Fibromyalgia (ACR 2010). Used to characterize Symtom Severity and Pain. It is composed by two subscales: Widespread Pain Index (WPI) (19 items) and the SSS (4 items) ranges from 0–12 There is a modified version developed in 2016. |
| Number of Items | 23 |
| Range | 0-31 |
| Responses options/scale |
Yes for the SSS goes from 0 - no problems to 3- severe problems |
| Developed for | Clinical practice |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered, Physician, Interviewer/assessor |
| Recommendations to score |
The questionnaire is divided in two subscales: the WPI is obtained by summing the body areas (out of 19 possible sites) in which the patient indicates they experienced pain during the preceding week, i.e., it can range from 0 to 19. The SSS consists of two parts: Part 1: the patient grades the severity over the last week of three somatic symptoms (waking unrefreshed, disturbed cognition, and fatigue) on a scale of 0–3, resulting in a maximum score of 9; Part 2: the patient grades the severity of the following three symptoms on a 4-point scale (0 = absent, 1 = slight, 2 = moderate, or 3 = severe), occurring during the previous 6 months: headaches, pain, or cramps in the lower abdomen and depression (a 0–12 total score). Furthermore, a poly-symptomatic distress (PSD) scale can be also calculated by the sum of the two component scores |

| Other Comments |
31.7% of the participants not meeting the FSDC criteria and 152/1283 (11.8%) of the participants meeting the FSDC criteria reported an improvement (slightly too very much better) of their health status since FMS-diagnosis (Chi2 = 55, p<0.0001). |
