Abstract: Objective. To investigate the reliability
and validity of the Spanish version
of the Fibromyalgia Rapid Screening
Tool (FiRST), a brief questionnaire for
the detection of fibromyalgia (FM) in
patients with diffuse chronic pain seen
at primary care health centres.
Method. The original FiRST French
questionnaire was adapted to a Spanish
version following the guidelines of the
Rheumatology Spanish Society Study
Group of FM, and the help provided
by professors of French and Spanish
Language. In a prospective and multicentre
study, patients with chronic pain
were initially divided into two groups:
a group that included patients that had
been diagnosed with FM according to
the 1990 ACR criteria and the 2010
ACR preliminary criteria (n=404), and
a non-FM (control) group composed of
rheumatoid arthritis (RA) (n=147) and
osteoarthritis (OA) (n=219) patients.
Patients from the FM group were
evaluated by assessing tender point
assessment, Widespread Pain Index
(WPI), Symptom Severity Scale (SSS),
FiRST questionnaire and Fibromyalgia
Impact Questionnaire (FIQ). The non-
FM group was evaluated by means
of FiRST, WPI and SSS. Sensitivity,
specificity and predictive value as well
as the correlation between the global
score and other parameters were assessed.
Results. 356 of 404 FM (88.1%) patients
who met the 1990 ACR criteria
and the ACR 2010 preliminary
criteria had a positive FiRST. In the
control group (AR plus OA), only 16
(4.4%) subjects had a positive FiRST.
The sensitivity value was 92% (95%
confidence interval CI: 88.9-95.1),
specificity 87.4% (95% CI: 80.8-94.0),
positive predictive value 95.7% (95% CI: 93.3-98.1), and negative predictive
value 78.2% (95% CI: 70.6-85.9).
A significant correlation between the
total FiRST score (patients with score
5 or 6) and WPI (p<0.0001), SSS
(p<0.0001), time to disease progression
(p<0.0001) and FIQ (p<0.0001)
Conclusion. FiRST questionnaire is a
useful tool for the detection of FM in
primary care health centres.
