扩展Barthel指数量表应用于脑卒中患者康复评定的信度研究

目的:研究扩展Barthel指数(EBI)评定脑卒中患者的重测信度及评测者间信度。方法:由第1位评定者应用EBI量表对30例脑卒中患者进行评定,3d内再次对该患者进行评定;第2位评定者在第1位评定者初次评定后2 d内再次对该患者进行评定。对不同评定者间的EBI结果进行等级间相关系数(ICC)分析以检验EBI的重测信度和评定者间信度。结果:第1位评定者两次评定总分的组内相关系数为0. 99(P 0. 01);第1位评定者与第2位评定者评定总分的组内相关系数为0. 98(P 0. 01)。结论:EBI量表应用于脑卒中患者康复评定时具有良好的重测信度及评测者间信度。

Reliability of extended Barthel index scale in rehabilitation assessment of stroke patients

Objective: To study the test retest reliability and interrater reliability of the extended Barthel index (EBI) in evaluation of Chinese stroke patients. Methods: All the stroke patients were assessed with an extended Barthel index scale by one evaluator, and the patients were evaluated again within 3 days after the assessment. The other one evaluator evaluated the patient within 2 days after the first assessment. The interlevel correlation coefficient (ICC) analysis of the EBI results among different evaluators was used to examine test retest reliability of EBI and the interrater reliability. Results: The interlevel correlation coefficient of total score of the first evaluator in two times assessment was 0.99 (P<0.01); The interlevel correlation coefficient of the total score of first evaluator and second evaluator was 0.98 (P<0.01). Conclusions: The EBI scale has good test retest reliability and interrater reliability evaluation for rehabilitation assessment of stroke patients.
