Abstract：Objective:Short Musculoskeletal Function Assessment(SMFA) was used to finish the Chinese version and its reliability and validity in patients with severe trauma were examined.Methods:English versions of SMFA was translated and back-translated according to the Brislin principles,the Chinese version of SMFA was evaluated through expert consultation method and adjusted for cultural adaptation.The 278 patients with severe trauma were investigated and their content validity,construct validity,construct validity,internal consistency and retest reliability were analyzed.Results:The Chinese version of SMFA contained 36 entries,and 3 common factors could be extracted by exploratory factor analysis.The cumulative variance contribution rate was 68.492％.The content validity(I-CVI) of each item ranged from 0.742 to 1.000,and the average content validity(S-CVI) was 0.893.The correlation coefficients of Chinese version of SMFA and World Health Organization Quality of Life assessment instrument-BREF(WHOQOL-BREF) Impact of Event Scale-Revised(IES-R) and Hospitals Anxiety and Depression Scale(HADS) were -0.672,0.398,0.324 and 0.462,respectively.The total Cronbach's α coefficient of the scale was 0.816,and the Cronbach's α coefficients of upper limb dysfunction,lower limb dysfunction and emotional dysfunction were 0.913,0.924 and 0.874,respectively.The total retest reliability of the scale was 0.853 and the retest reliability of all dimensions were 0.903,0.854 and 0.829.Conclusions:The Chinese version of SMFA had better reliability and validity and was suitable for the functional evaluation and research of patients with severe trauma.
