Social validity of changes in informativeness and efficiency of aphasic discourse following linguistic specific treatment (LST).
This study presents the results of an analysis of pragmatic aspects of language samples obtained from five agrammatic aphasic individuals prior to and following Linguistic Specific Treatment (LST). Clinically and statistically significant positive changes in informativeness and efficiency were documented in posttreatment samples. Analysis of communicative competence (i.e., naïve listeners' ratings of pre- and posttreatment audiotaped samples), was undertaken to examine the social validity of quantified changes. Mean ratings across listeners were computed to evaluate their subjective perceptions of general communicative constructs. Results indicated that objectively measured changes in pragmatic aspects were perceptible to naïve listeners, however, to varying degrees across participants and constructs.
