Objective： To assess the validity and reliability of the Chinese version of the Impact on Participation and Autonomy Questionnaire（IPA） among stroke patients.Methods： A total of 271 stroke patients participated in this cross-sectional study.The data were analyzed using SPSS17.0 software package.Results： The Cronbach＇s alpha of IPA-I and IPA-II were 0.937 and0.726,respectively.TheCronbach＇salphaandsplit-halfreliabilitycoefficientwere0.965and0.925forautonomyindoors;0.959 and 0.908 for family role;0.943 and 0.910 for social life and relationship;and 0.667 and 0.678 for autonomy outdoors.Exploratory Factor Analysis（EFA） of the IPA yielded four factors,which explained 80.572% variance.Conclusion： The IPA is a valid and reliable instrument to assess participation and autonomy level of stroke patients.
