Responsiveness, Reliability, and Minimally Important and Minimal Detectable Changes of 3 Electronic Patient-Reported Outcome Measures for Low Back Pain: Validation Study.

ABSTRACT:

Background

The Roland Morris Disability Questionnaire (RMDQ), visual analog scale (VAS) of pain intensity, and numerical rating scale (NRS) are among the most commonly used outcome measures in trials of interventions for low back pain. Their use in paper form is well established. Few data are available on the metric properties of electronic counterparts.

Objective

The goal of our research was to establish responsiveness, minimally important change (MIC) thresholds, reliability, and minimal detectable change at a 95% level (MDC₉₅) for electronic versions of the RMDQ, VAS, and NRS as delivered via iOS and Android apps and Web browser.

Methods

We recruited adults with low back pain who visited osteopaths. We invited participants to complete the eRMDQ, eVAS, an
