Translation and reliability and validity testing of Chinese version of InterRAI Home Care

Abstract:Objective To translate the English version of InterRAI Home Care into the Chinese version and to evaluate its reliability and validity. Methods The translation and culturally adaptation of InterRAI Home Care were performed to construct the Chinese version of InterRAI Home Care. Using the convenience sampling,215 subjects who met eligibility criteria were recruited from community health care centers of Dongcheng District,Beijing. We used the Chinese version of InterRAI Home Care,Modified Barthel Index scale,Modified IADL scale,and Mini-Mental State Examination scale to assess the elderly. Results The Cronbach’s α of Chinese version of InterRAI Home Care was 0.871 which confirmed the internal consistency. The I-CVI was 1.0 for all items,and the S-CVI was also 1.0. The inter-rater reliability was confirmed by Pearson correlation coefficient which ranged from 0.916 to 0.942. The criterion-related validity was established by Pearson correlation coefficients which ranged from -0.999 to -0.810 between scores of the ADL and Modified Barthel Index scale. The criterion-related validity was established by Pearson correlation coefficients which ranged from -0.996 to -0.962 between scores of the IADL and Modified IADL scale. The criterion-related validity was established by correlation coefficient of 1.0 between cognitive disorder of CAPs and MMSE scale. The agreement coefficient was 1.0 between CAPs and doctors’ diagnoses. Conclusion The Chinese version of InterRAI Home Care was demonstrated to be reliable and valid among community dwelling elderly.
