Abstract
BACKGROUND: World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) provided a standardized method for measuring the health and disability and the traditional Chinese version has not been developed. AIMS: To describe the process of developing the traditional Chinese version of the WHODAS 2.0 36-item version and to evaluate the concurrent validity and test-retest reliability of this instrument. METHODS: The study was conducted in two phases. Phase I was the process of translation of WHODAS 2.0 36-item version. Phase II was a cross-sectional study. The participants were 307 adults who were tested the validity and reliability of draft traditional Chinese version. 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. There was a valid and reliable measurement scales for evaluating functioning and disability status. CONCLUSION: For disability eligibility system of Taiwan government to measure the disability, the traditional Chinese version of the WHODAS 2.0 provided valuable evidence to design the assessment instrument.
