Abstract：Objective To evaluate the validity and reliability of a Chinese version of neck pain and disability scale (NPAD). Methods NPAD was translated into Chinese (SC-NPAD) and tested in the outpatient service of orthopaedic department in Changhai Hospital affiliated to the Second Military Medical University. From May 2008 to March 2009, total of 117 patients were involved and 106 (90.1%) of them completed the first questionnaire. Five to seven days later, 36 cases were randomly chosen for the second questionnaire and 35 patients completed. Reliability assessment was determined by calculating internal consistency and repeatability. At the same time, SF-36 scale (SF-36) was distributed for comparison, also, correlation analysis was used to determine the relationship between SC-NPAD and SF-36. Results Factor analyses demonstrated that the internal consistency of the four subscales for NPAD including "pain", "disability", "neck-specific function" and"emotional and cognitive influences" subscales, was 0.935, 0.952, 0.955 and 0.910, respectively, with a consistent test-retest reliability (r = 0.813, P = 0.000). All the subscales were significantly correlated with SF-36 and five SF-36 domains associated with the items of physical functioning, social functioning, role-physical, vitality and bodily pain. Conclusion SC-NPAD has good reliability and validity, which is fit for assessments for Chinese neck pain patients.
