title: Predicting the Western Aphasia Battery Aphasia Quotient.
abstract: Administration of the Western Aphasia Battery (WAB) yields a total score termed the Aphasia Quotient (AQ), which is said to reflect the severity of the spoken language deficit in aphasia. This score is a weighted composite of performance on 10 separate WAB subtests. Based on data from 100 patients, all 10 subtests were found to correlate highly with each other and with the AQ, but the score from one subtest, Information Content, was the best predictor of the AQ. Time postonset had no influence on the relationships among the subtests or between the 10 subtests and the AQ. These findings are useful in understanding the Western Aphasia Battery and in interpreting the Aphasia Quotient.
