Abstract
Methods
Four-hundred and two subjects were interviewed with the Chinese version of the WHODAS 2.0. Patients also completed the Functional
Assessment of Cancer Therapy-Breast (FACT-B). Internal consistency reliability was measured by Cronbach’s α. Spearman correlation
coefficients between total scores and subscales of FACT-B and WHODAS 2.0 were examined to get the convergent validity. Independent
sample t test was applied to test discriminant validity by comparing the difference of disability scores for different degree of relevant
symptoms. The factor structure of the WHODAS 2.0 was examined by Exploratory Factor Analysis (EFA) and Confirmatory Factor
Analysis.

Results
The Chinese version of the WHODAS 2.0 showed satisfactory internal consistency (r, 0.72–0.92), convergent validity and discriminant validity. After 4 items(item D2.2: standing up; D3.3: eating; D4.5: sexual
activities; and D6.3: living with dignity) were excluded, EFA identified seven separate factors for ‘Self-care and Household
activities,’ ‘Getting along with people,’ ‘Getting around,’ ‘Understanding,’ ‘Communicating,’ ‘Participation in society’ and
‘Family burden’(explained variance 72.13 %). The reduced model also presented the best fit [Confirmatory Fit Index = 0.914,
Tucker-Lewis Index = 0.900, Root Mean Square Error of Approximation = 0.069] compared with the model suggested by EFA and
hypothesized a prior.
