自编简易临床失语量表的信度和效度验证

The reliability and validity of the self-designed simple clinical aphasia scale

目的:对自编简易临床失语量表进行信度和效度检验。方法:对符合标准的45例正常受试者和46例卒中后失语患者进行自编简易临床失语量表的2次评估:不同评定者间评估、汉语失语成套测验(Aphasia Battery of Chinese,ABC)量表评估。计算本量表的重测信度、内部一致性、评定者间信度及校标效度、结构效度、区分效度。结果:简易临床失语量表的重测信度为0.867~0.990;量表克龙巴赫α系数为0.873;评分者间信度为0.862~0.992;因子分析KMO为0.825;区分效度P<0.001;校标效度为0.805~0.953。结论:简易临床失语量表对脑卒中后失语症患者的诊断具有较好的信度和效度,可作为卒中后失语症患者言语功能障碍的测评工具。

Objective:To test the reliability and validity of the self-designed simple clinical aphasia scale.Methods:A total of 45 normal subjects and 46 patients with aphasia after stroke were assessed twice with the self-designed clinical aphasia scale among different raters,and Aphasia Battery of Chinese(ABCJ)scale evaluation was conducted.The retest reliability,internal consistency,inter rater reliability,calibration validity,construction validity and discriminant validity were calculated.Results:The retest reliability of the simple clinical aphasia scale was 0.867-0.990.The Cronbach’sαcoefficient of the scale was 0.873.The reliability inter the raters was 0.862-0.992.Factor analysis KMO was 0.825,discriminant validity was P<0.001,and calibration validity was 0.805-0.953.Conclusion:The simple clinical aphasia scale has good reliability and validity in the diagnosis of Chinese aphasia after stroke,and can be used as a tool to evaluate the language impairment of patients with aphasia after stroke.
