Abstract

|
This study aimed at investigating the validity and reliability of the Daegu Diagnostic Aphasia Examination (DDAE). The DDAE has been developed to assess aphasics’ receptive and expressive language ability. One hundred and forty eight aphasics (96 males and 52 females) diagnosed as aphasics participated in this study. Reliability coefficients showed that the DDAE was highly consistent and accurate (Cronbach’s a = .76~.82). For its’ content-validity, a 5-point scale was administered. Four speech and language pathologists served as evaluator. The receptive language mean score was 4.29, the expressive language mean score was 4.09, and the right-hemisphere function mean score was 4.00. For construct validity, the correlation total scores were calculated. The results showed a significant correlation.
