  RESULTS
  The reliability of Cronbach's α and ICC in the WHODAS 2.0 traditional Chinese version were 0.73-0.99 and 0.8-089, respectively. The content validity was good (r=0.7-0.76), and the concurrent validity was excellent in comparison with the WHOQOL-BREF (p<0.5). The construct validity, the model was explained total variance was 67.26% by the exploratory factor analysis (EFA) and the confirmatory factor analysis (CFA) illustrated the traditional Chinese version was good to assess disability.
