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

Abstract:

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's α coefficient 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.
