OBJECTIVES: To study the validity and nature of self-assessed
symptoms among patients with fibromyalgia syndrome (FMS) and
to compare our data with findings reported in the US. To
determine whether tender point scores correlate with
self-reported pain and other symptoms and to study the
influence of disease duration.
METHODS: Tender point scores
were assessed in 113 consecutive patients with FMS. All
patients completed 2 self-assessment questionnaires (an
extended Campbell list, the Enschede Fibromyalgia
Questionnaire, and the Dutch Arthritis Impact Measurement
RESULTS: The self-assessed symptoms of the Dutch FMS
patients seem to be valid and are comparable with those of
American patients. No association between disease duration and
number of self-reported symptoms was found. An association
between self-reported pain and mean tender point score was
lacking for patients with disease of shorter duration and was
weak for patients with disease of longer duration.
CONCLUSIONS: The use of a self-report questionnaire for
patients with FMS is feasible and appears to be valid. Tender
point scores and self-reported pain represent very different
aspects of pain in FMS.
