Randomized Controlled Trial Comparative Study Clinical TrialUse of a numerical rating scale as an answer modality in ankylosing spondylitis-specific questionnaires.
To determine the agreement of scores on the original visual analog scale (VAS) or Likert scale of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), and Dougados Functional Index (DFI) with scores on a numerical rating scale (NRS). To assess the reproducibility and responsiveness of the instruments with the original scale and NRS. ⋯ Although large variability between the scores on the original answer scales and the NRS was observed, the BASDAI, BASFI, and DFI can be administered with an NRS, which does not show important differences compared with the original scales.

Comparative StudyDoes the label "fibromyalgia" alter health status, function, and health service utilization? A prospective, within-group comparison in a community cohort of adults with chronic widespread pain.
To determine if assigning the label of fibromyalgia (FM) to individuals with chronic widespread pain has a significant effect on long-term health status, function, and health service utilization. ⋯ The FM label does not have a meaningful adverse affect on clinical outcome over the long term. Further research is necessary to document the short- and long-term effect of labeling in the chronic pain patient.
