Our primary outcome was the measure ’s minimal important difference ( MID ) .
Conclusions In this focused evidence review , the most evidence on key psychometric properties in chronic musculoskeletal pain population s was found for the ODI , RMDQ , SF-36 BPS , NRS , and VAS .
Background Developing successful interventions for chronic musculoskeletal pain requires valid , responsive , and reliable outcome measures .
The Minneapolis VA Evidence -based Synthesis Program completed a focused evidence review on key psychometric properties of 17 self-report measures of pain severity and pain-related functional impairment suitable for clinical research on chronic musculoskeletal pain .
Comparative Responsiveness of Pain Outcome Measures Among Primary Care Patients With Musculoskeletal Pain
Background : Comparative responsiveness data are needed to inform choices about pain outcome measures . Objectives : To compare responsiveness of pain intensity , pain-related function , and composite measures , using data from a r and omized trial and observational study . Research Design : Analysis of responsiveness . Subjects : A total of 427 adults with persistent back , hip , or knee pain were recruited from primary care . Methods : Participants completed  Brief Pain Inventory , Chronic Pain Grade ( CPG ) , Rol and disability ,  SF-36 bodily pain  , and pain global rating of change measures . We used the global rating as the anchor for st and ardized response mean and receiver operating characteristic curve analyses . We used the distribution-based st and ard error of measurement to estimate minimally important change . To assess responsiveness to the trial intervention , we evaluated st and ardized effect size statistics stratified by trial arm . Results : All measures were responsive to global improvement and all had fair-to-good accuracy in discriminating between participants with and without improvement . SF bodily pain was less responsive than other measures in several analyses . The 3-item PEG was similarly responsive to full Brief Pain Inventory scales . CPG and SF bodily pain were less responsive to the trial intervention and did not perform well among participants with hip/knee pain . Agreement between anchor and distribution-based methods was modest . Conclusions : If a brief measure is desired , the 3-item PEG is more responsive than the SF bodily pain scale . CPG and SF bodily pain scales may be relatively poor choices for trial outcome assessment . Both anchor and distribution-based methods should be considered when determining clinical ly important change
