[Purpose] To establish the test-retest reliabilities, minimal detectable change of the Short form Barthel Index and associations with stroke-specific impairments. [Subjects and Methods] The Short form-Barthel Index assessment was tested on 24 chronic stroke patients twice, 7 days apart. A relative reliability index (ICC), Weighted Kappa Coefficients was used to examine the level of agreement of test-retest reliability for SF-BI, Absolute reliability indices, including the standard error of measurement and the minimal detectable change. The validity was demonstrated by spearman correlation of SF BI-total score with Postural Assessment Scale for Storke, Fugl Meyer Assessment. [Results] There was excellent agreement between test-retest for individual items of BI and total score ICC=0.91 and it all showed acceptable SEM and MDC were 2.83 score, 7.84 score respectively. The item-to-total correlations were all significant, ranging from r=0.83-0.92. SF-BI showed good internal consistency. Individual items also possessed high internal consistency 0.82-0.86. The SF-BI and total score were demonstrated high concurrent validity with the PASS, FMA. [Conclusion] This study has demonstrated that the SF-BI is a useful instrument with high test-retest reliability, Absolute reliability indices, internal consistency and validity.
[目的]建立简化巴氏指数（Short form Barthel Index）的重测信度、最小可检测变化及其与卒中特异性损伤的相关性。[对象与方法]对24例慢性卒中患者进行简化巴氏指数评估，两次评估间隔7天。采用相对信度指标（组内相关系数，ICC）、加权kappa系数检验简化巴氏指数重测信度的一致性水平，采用包括测量标准误和最小可检测变化在内的绝对信度指标。通过简化巴氏指数总分与卒中姿势评定量表、Fugl Meyer评定量表的斯皮尔曼相关性来证明效度。[结果]巴氏指数各单项及总分的重测之间一致性良好，ICC = 0.91，测量标准误和最小可检测变化分别为2.83分、7.84分，均显示可接受。各项目与总分的相关性均显著，范围为r = 0.83 - 0.92。简化巴氏指数显示出良好的内部一致性。各单项也具有较高的内部一致性，范围为0.82 - 0.86。简化巴氏指数及其总分与姿势评定量表、Fugl Meyer评定量表具有较高的同时效度。[结论]本研究表明，简化巴氏指数是一种有用的工具，具有较高的重测信度、绝对信度指标、内部一致性和效度。
