FACTORS INFLUENCING APHASIA AND ITS RECOVERY (I)

EXPLORATION OF EVALUATION METHODS

Abstract

When analyzing factors influencing aphasia and its recovery, it is the most important basic issue to select the most proper evaluation method which indexes ability of language and to realize the meaning of the method, grasping their excellences and defects.
This study explored the following three different categories of evaluation methods; an ordinal scale evaluation in views of verbal communication of daily living, SLTA as a test battery, and an evaluation method adopting factors of factor analysis of SLTA as indexes of ability of language.
SLTA was the most appropriate evaluation which indexes ability of language and its recovery. The total scores of SLTA was the most significant index among the items of SLTA. However, the ordinal scale evaluation could not be ignored as the indexes of recovery of ability of language. Factor analysis evaluation was not proper for that purpose.
Comparative analysis of these three evaluation methods and internal items of each method also showed a significant trend in the meanings, excellences and defects of the methods, and correlations among them.
