Reliability and validity of Chinese Rehabilitation Research Center Standard Aphasia Examination / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo investigate the reliability and validity of Chinese Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) among patients with aphasia after cerebral injury. Methods40 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.ResultsThe interclass correlation coefficients>0.9, while the Cronbach α 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.ConclusionCRRCAE shows a good retest reliability and good internal consistency. The total scale of CRRCAE can be correlated with serious level of aphasia effectively.
