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 study the reliability and validity of CRRCAE in the evaluation of patients with aphasia of cerebrovascular diseases. Methods CRRCAE scale was used to measure the reliability and validity of 20 patients with aphasia. The interclass correlation coefficients were used to represent the reliability of the scale. The CRRCAE scale was used to evaluate the reliability and validity of the questionnaire. Subproject tests were conducted to assess the validity of the scale with aphasia index and subtest in Western Aphasia Battery (WAB). Results The CRRCAE scale had a correlation coefficient of> 0.9. The total score of CRRCAE had a higher correlation with the WAB index of aphasia (r = 0.948, P <0.01). The sensitivity scale of CRRCAE was 0.94. Conclusions CRRCAE has good reliability and sensitivity. The total score of CRRCAE is effective in reflecting the severity of aphasia and can be used as a quantitative index in clinical and verbal rehabilitation of patients with aphasia.
