Statistical Prediction of Change in Aphasia

Abstract

We reviewed speech, language, and biographical data on 144 asphasic patients who had suffered left hemisphere cerebral vascular accidents. Using a step-wise multiple regression procedure, we attempted to predict change in severity of aphasia at three, six, and 12 months postonset based on performance at one, three, and six months post-onset. Our results suggest statistical prediction of change is feasible. Multiple correltion coefficients ranged from 0.74 to 0.94
