Abstract: ObjectiveTo evaluate the reliability and validity of the of Disability Assessment Schedule Ⅱ of World Health Organization(WHO-DASⅡ) applied in assessment of the function of disabled athletes.Methods56 disabled people,26 wheelchair basketball athletes and 30 patients,were sampled and completed WHO-DASⅡ questionnaire.The test and re-test had been administrated in 10 days.Barthel Index(BI) and Sports Classification Test had been implemented for the functioning assessment.ResultsThe test-retest reliability for WHO-DASⅡ in six dimensions were: 0.978,0.807,0.938,0.877,0.998,0.935,0.986 and all were in very significant level(P<0.01).There were negative correlation between WHO-DASⅡ scores and BI in total and in every dimension,the correlation coefficients were:-0.77,-0.17,-0.71,-0.82,-0.33,-0.73,-0.61.The correlation coefficients between WHO-DASⅡ total and six dimensional scores and the grade of sports classification were:-0.741,-0.378,-0.806,(-0.541),-0.293,-0.510,-0.677.ConclusionWHO-DASⅡ can be used in assessing the function of disabled athletes.
