Clinically Important Change to the Roland Morris Disability Questionnaire and Numerical Pain Scale in Older People with Nonspecific Low Back Pain

Type: preprint
Abstract: The purpose of this study was to evaluate the clinically important change of patient-reported outcome measurement instruments (PROMs) Roland-Morris Disability Questionnaire (RMDQ) and Numeric Rating Scale (NRS) in older adults with chronic low back pain. The study used the database from the ESCAPE (Exercise for chronic back pain in older people) clinical trial, which is under development and aims to investigate the effectiveness of group exercise in older people with chronic back pain. Patients aged 60 years or older who met the eligibility criteria were included in the study. PROMs outcomes were assessed at baseline and 8 weeks after randomization. The external anchor for assessing responsiveness and MIC estimates was the global perceived effect (GPE) scale, assessed 8 weeks after randomization. The clinically important change was with and without the “slightly improved” GPE category. Analysis was performed using the ROC curve with the least squares method. The median and 25th percentile, and logistic regression were used as sensitivity analyses. Responsiveness was assessed using two approaches: the construct approach and the criterion approach. The results showed that the RMDQ and the NRS were responsive to change in older adults with chronic low back pain, and that the MIC estimates varied according to the GPE category and the analysis method. The study provides useful information for clinicians and researchers who use these PROMs in this population.
