AN INVESTIGATION OF THE SENSITIVITY OF THE REPORTER'S TEST TO EXPRESSIVE LANGUAGE DISTURBANCES
The study was designed to investigate the sensitivity of the Reporter's Test to expressive language disturbances. One hundred and forty-four normal adults and 24 left brain-injured aphasic adults were given a test battery consisting of: the Reporter's Test (DeRenzi & Ferrari, 1978), the Token Test - part V (DeRenzi & Vignolo, 1962), the Word Fluency Measure (Wertz, Keith, & Custer, 1971), an Analysis of Connected Speech Samples (Yorkston & Beukelman, 1980), a Ten-Item Sentence Repetition Task, and the Imitator's Test. A significant difference was found between normal and asphasic adults' total scores and test times on the Reporter's Test. In addition, neither age nor educational level played a significant part in the performances of the normal subjects on the Reporter's Test. Interjudge reliability, test-retest reliability, and concurrent validity were established for the Reporter's Test. The Reporter's Test was found to be as sensitive as the Word Fluency Measure and the Token Test - part V to expressive language disturbances. The Reporter's Test was found to be a more sensitive measure than the Analysis of Connected Speech Sample. Hit rates and indices of determination were determined for all test measures. In addition, several test battery proposals were suggested.
