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 .
Performance of a Patient Reported Outcomes Measurement Information System (PROMIS) Short Form in Older Adults with Chronic Musculoskeletal Pain.
OBJECTIVE To assess reliability , validity , and responsiveness of a 29-item short-form version of the Patient Reported Outcomes Measurement Information System ( PROMIS ) and a novel “ impact score ” calculated from those measures . DESIGN Prospect i ve cohort study . SETTING Rural primary care practice s. SUBJECTS Adults aged ≥ 55 years with chronic musculoskeletal pain , not currently receiving prescription opioids . METHODS Subjects completed the PROMIS short form at baseline and after 3 months . Patient subsets were compared to assess reliability and responsiveness . Construct validity was tested by comparing baseline scores among patients who were or were not applying for Worker 's Compensation ; those with higher or lower catastrophizing scores ; and those with or without recent falls . Responsiveness was assessed with mean score changes , effect sizes , and st and ardized response means . RESULTS Internal consistency was good to excellent , with Cronbach 's alpha between 0.81 and 0.95 for all scales . Among patients who rated their pain as stable , test-retest scores at 3 months were around 0.70 for most scales . PROMIS scores were worse among patients seeking or receiving worker 's compensation , those with high catastrophizing scores , and those with recent falls . Among patients rating pain as “ much less ” at 3 months , absolute effect sizes for the various scales ranged from 0.24 ( Depression ) to 1.93 ( Pain Intensity ) . CONCLUSIONS Results indicate that the PROMIS short 29-item form may be useful for the study of patients with chronic musculoskeletal pain . Our findings also support use of the novel “ impact score ” recommended by the National Institutes of Health ( NIH ) Task Force on Research St and ards for Chronic Low Back Pain
