TI  - Validity of the Japanese Core Outcome Measures Index (COMI)-Back for thoracic and 
      lumbar spine surgery: a prospective cohort study.

AB  - PURPOSE: To investigate the psychometric properties of the Japanese version of 
      the Core Outcome Measures Index-Back (COMI-Back), only recently published 
      according to the established linguistic and cultural conversion guidelines, in 
      patients undergoing spine surgery. METHODS: We recruited 145 patients who 
      underwent thoracic or lumbar spine surgery in one of the five specific tertiary 
      care institutions. They were asked to complete a booklet questionnaire (the 
      COMI-Back, the Numerical Rating Scale for pain, the Short Form-12, Euro-QOL-5 
      dimensions, and Oswestry Disability Index) at baseline and 12 months 
      postoperatively to investigate floor/ceiling effect, construct validity, and 
      postoperative responsiveness. The patients were also asked to answer an anchor 
      question (Global Treatment Outcome) to analyze the minimum clinically important 
      difference (MCID) by receiver operating characteristics curves. Of the 145 
      patients, 112 completed the study. Another group of 59 volunteers with chronic 
      symptoms completed the questionnaire twice within a 7-14-day interval for the 
      test-retest reproducibility. RESULTS: The COMI summary score displayed no notable 
      floor or ceiling effects. Except for symptom-specific well-being, the individual 
      COMI domains and the COMI summary score correlated as expected with the scores of 
      the chosen reference measures (rho = 0.4-0.8). A similar trend was observed between 
      the pre-/postoperative changes in the COMI score and those in the reference 
      measures. The MCID for the COMI summary score was 2.5. The intraclass correlation 
      coefficient and minimum detectable change (MDC95%) were 0.93 and 1.26, 
      respectively. CONCLUSION: The Japanese COMI-Back was a reliable and responsive 
      questionnaire in our Japanese patients undergoing thoracic/lumbar spine surgery.
