目的 汉化血液透析跌倒风险指数（dialysis falls risk index，DFRI）量表并检验其信效度。 方法 遵循Brislin翻译模型对DFRI进行翻译、文化调试和预调查，形成中文版DFRI。使用该量表对衡阳市两所医院141例血液透析（hemodialysis，HD)患者进行评估，以检验其信效度。 结果 中文版DFRI共7个条目，提取3个公因子，累计方差贡献率61.729%，内容效度指数为0.80~1.00，量表平均内容效度指数为0.967，Cronbach’s α系数为0.507，重测信度为0.948，评定者信度为0.926。该量表ROC曲线下面积为0.719，最佳截点值为≥5.25分，敏感度为0.773，特异度为0.580。 结论 中文版DFRI量表具有较好的信效度及诊断效能，简捷有效，可用于我国HD患者跌倒风险评估。

Objective To develop the Chinese version of the Dialysis Falls Risk Index (DFRI) and to test its reliability and validity. Methods According to the Brislin forward-backward model,the Chinese version of DFRI was developed by translation,cultural adjustment and pre-investigation.The reliability and validity of the Chinese version DFRI were evaluated in 141 hemodialysis (HD) patients from 2 hospitals in Hengyang. Results The Chinese version of DFRI included 7 items,clustering into 3 common factors,with a cumulative variance contribution rate of 61.729%.The item Level Content Validity Index (I-CVI) of the Chinese version of DFRI was from 0.80 to 1.00,and the Scale-level Content Validity index (Average) (S-CVI/Ave) was 0.967.The Cronbach’s α coeffient and the retest reliability were 0.507 and 0.948 respectively.The inter-rater reliability was 0.926.For the Chinese version of DFRI,the area under the ROC curve was 0.719,the best cut-off point was ≥5.25 points,the sensitivity was 0.773,and the specificity was 0.580. Conclusions The Chinese version of DFRI is simple and effective,with good reliability,validity and diagnostic efficacy.It can be used to assess the fall risk of HD patients in China.
