Statistical Prediction of Change in Aphasia 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 ...

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
