To translate the English version of the 9-item Shared Decision Making Questionnaire (SDM-Q-9) into Chinese, and to test its reliability and validity in Chinese version.
 Methods: A total of 720 inpatients were recruited randomly from 6 hospitals in Changsha and were investigated using the Chinese version of SDM-Q-9. SPSS 23.0 and AMOS 23.0 were used to test the reliability and validity.
 Results: There were 660 participants completed and returned valid questionnaires (valid return rate was 91.7%). An analysis of internal consistency yielded a Cronbach's α at 0.945 and the correlation of test-retest reliability was 0.319 for whole instrument. The correlations between the items and total scale ranged from 0.790 to 0.879 (P<0.001). A single factor was extracted by exploratory factor analysis and it could explain 69.824% of the total variance. The confirmatory factor analysis revealed a good model fit. The goodness-of-fit index (GFI), adjusted goodness-of-fit index (AGFI), comparative fit index (CFI), normal fit index (NFI), and root mean square residual (RMR) were 0.870, 0.784, 0.926, 0.921, and 0.054, respectively.
 Conclusion: The Chinese version of SDM-Q-9 is proved to be reliable and eligible except the correlation of test-retest reliability is relatively low. It can be used to assess the patient's perspective in the process of shared decision making in clinical situation.
