Measuring pain in systemic sclerosis: comparison of the short-form McGill Pain Questionnaire versus a single-item measure of pain.

Objective: Studies of pain in systemic sclerosis (SSc) have used a variety of measures, including single-item measures and the 15-item short-form McGill Pain Questionnaire (MPQ-SF). The objective of our study was to compare the performance of the MPQ-SF to a single-item pain numerical rating scale (NRS) and determine whether the MPQ-SF effectively differentiates between sensory and affective components of pain in SSc.

Methods: A cross-sectional, multicenter study of 1091 patients from the Canadian Scleroderma Research Group Registry who completed the MPQ-SF and pain NRS.
