WAB汉化版失语症诊断量表的信度与效度分析
The Analysis of Validity and Reliability of the Chinese Version of the Western Aphasia Battery in Chinese Aphasia Patients
摘要: 目的：研究西部失语症评定量表(Western Aphasia Battery, WAB)的汉化版在评测中国失语症患者中的信度与效度。方法：应用汉化版WAB量表评测47例于上海市阳光康复中心接受治疗的失语症患者以及29例正常人，使用SPSS 24.0统计学软件，引用克隆巴赫–阿尔法信度系数，评估量表的内部一致性信度，采用结构效度、聚合效度和区分效度评估量表的效度。结果：汉化版WAB量表信度系数在0.8以上，整体信度系数高达0.959，大多数小题区分度较高。结论：汉化版WAB量表具有较好的信度、效度与结构设计，可以用于评估中国患者失语症严重程度。但其大题间相关度过高，部分小题区分度过低，自发言语部分信度低，需改进。
Abstract: Objective: To investigate the reliability and validity of the Chinese version of the Western Aphasia Battery (WAB) among Chinese patients with aphasia. Methods: 47 patients with aphasia at Shanghai Rehabilitation Center and 29 normal people were measured by Chinese version of WAB. To assess internal consistency reliability, Cronbach’s alpha coefficient was measured. Construct-related validation, convergent validity and discriminant validity were analyzed for overall validity of Chinese version WAB. Results: The reliability of Chinese version WAB exceeds 0.8, with an overall reliability coefficient as high as 0.959 and an excellent level of discrimination for most of the subtests. Conclusions: Chinese version WAB with good reliability, validity and structural design could effectively evaluate the severity of patients with aphasia. But the correla-tion between the major components is too high while the distinction between some sub-tests and the reliability of the spontaneous speech section are low and need improving.
