AB  - PURPOSE: To investigate the psychometric properties of the Japanese version of 
      the Core Outcome Measures Index-Neck (COMI-Neck) in patients undergoing cervical 
      spine surgery. METHODS: A total of 177 patients undergoing cervical spine surgery 
      for spinal disorders from April to December 2017 were enrolled. Patient-reported 
      outcomes (PROs) included EuroQOL, Neck Disability Index, and treatment 
      satisfaction. To address whether the questionnaire's scores relate to other 
      outcomes based on a predefined hypothesis, the correlations between the COMI-Neck 
      and the other PROs were measured (Spearman's rank correlation coefficients). The 
      minimum clinically important difference (MCID) of the COMI summary score was 
      calculated using the receiver operating characteristic (ROC) curve with a 7-point 
      Likert scale of satisfaction with the treatment results. To assess 
      reproducibility, another group of 59 volunteers with chronic neck pain were asked 
      to reply to the COMI-Neck twice with an interval of 7-14 days. RESULTS: The COMI 
      summary score showed no floor or ceiling effects preoperatively or 
      postoperatively. Each of the COMI domains and the COMI summary score correlated 
      to the hypothesized extent with the scores of the reference questionnaires 
      (rho = 0.40-0.79). According to the ROC curve with satisfaction (including "very 
      satisfied" and "satisfied"), the area under the curve and MCID of the COMI 
      summary score were 0.78 and 2.1. The intraclass correlation coefficient and the 
      minimum detectable change (MDC 95%) of the COMI summary score were 0.97 and 0.77. 
      CONCLUSION: The Japanese version of the COMI-Neck is valid and reliable for 
      Japanese-speaking patients with cervical spinal disorders.
