AB  - STUDY DESIGN: Registry-based repeated-measures psychometric validation of the 
      Danish Oswestry Disability Index (ODI). OBJECTIVE: The goal was to use classical 
      and modern psychometric validation methods to assess the measurement properties 
      and the minimally clinical important difference (MCID) of the ODI in a Danish 
      cohort of patients with chronic low back pain being treated with spinal surgery. 
      SUMMARY OF BACKGROUND DATA: Scores for the ODI, EQ-5D, SF-36, leg pain, back 
      pain, and a general rating of pain item from 800 patients with chronic low back 
      pain were extracted from the National Danish Spine Registry (DaneSpine) at 
      baseline and 1-year postspine surgery. METHODS: Confirmatory factor analysis and 
      item response theory (IRT) models were used to assess the psychometric properties 
      of the ODI. MCID was also calculated based on generic legacy PROMs (EQ-5D and 
      SF-36) and follow-up pain scores. RESULTS: While ODI did not fit a Rasch model, 
      adequate fit to a confirmatory factor analysis and a two-parameter item response 
      theory model was found when accounting for differential item functioning across 
      diagnostic subgroups (degenerative spondylolisthesis, spondylosis, spinal 
      stenosis, and herniated intervertebral disc). In addition, each group exhibited 
      substantially different MCID values. CONCLUSION: The Danish version of the ODI is 
      valid and responsive, but only within each of the four major diagnosis subgroups: 
      degenerative spondylolisthesis, spondylosis, spinal stenosis, and herniated 
      intervertebral disc. LEVEL OF EVIDENCE: 4.
