中国康复研究中心汉语标准失语症检查量表的信度与效度分析

Reliability and validity of Chinese Rehabilitation Research Center Standard Aphasia Examination

目的研究“中国康复研究中心汉语标准失语症检查量表”(CRRCAE)在评测脑血管疾病失语症患者中的信度和效度。方法运用CRRCAE量表对20例失语症患者进行量表的信度和效度分析,引用组内相关系数(interclass correlation coeffi-cients)表示量表的可信度;将CRRCAE量表的总分和分项目测验同西方失语症量表(Western Aphasia Battery,WAB)的失语症指数和分测验进行量表的效度研究。结果CRRCAE量表总评分组内相关系数>0.9;CRRCAE的总评分同WAB的失语症指数有较高的相关性(r=0.948,P<0.01);其敏感效应尺度为0.94。结论CRRCAE具有良好的信度和敏感度,其总分在反映失语症严重程度方面具有较好的有效性,可以作为在失语症患者的临床和语言康复中量化的指标。

Objective To investigate the reliability and validity of Chinese Rehabilitation Research Center Standard Aphasia Examination （CRRCAE） among patients with aphasia after cerebral injury. Methods 40 patients were measured using the CRRCAE. For reliability, interclass correlation coefficients were analyzed. For validity, the correlation coefficients of the aphasia quotients and 4 items of CRRCAE and Western Aphasia Battery （WAB） were analyzed. Results The interclass correlation coefficients〉0. 9, while the Cronbach a of total scale was 0. 9411, the scale of the comprehension was 0.8677, the scale of express was 0. 8889. CRRCAE had positive relationship with WAB（with the aphasia quotients, r=0. 948, P〈0.01 ）. The effect size statistics scale was 0.94. Conclusion CRRCAE shows a good retest reliability and good internal consistency. The total scale of CRRCAE can be correlated with serious level of aphasia effectively.
