Attitudes Toward and Perceived Communicative Competence of Individuals with Aphasia Using Speech-Generating Devices. (2nd January 2022) - Brock, Kris L.
Abstract: The purpose of this study was to investigate the effects of interface display and respondent group on listener attitudes toward and perceived communicative competence of persons with aphasia. The Attitudes Toward Nonspeaking Persons scale and the Communicative Competence Scale was used to measure listener attitudes and communicative competence, respectively. A 2 × 3 mixed factorial design was used. Interface display videos served as the within-subjects variable (i.e., grid and scene displays), and the respondent group served as the between-subjects variable. A total of 113 respondents (i.e., undergraduate lower-division students, undergraduate upper-division students, and family caregivers of individuals with aphasia) watched an individual with aphasia using a grid display in one video and a scene display in another video. The respondents completed the two scales. Significant main effects ( p < .05) were found for interface display and respondent group. The use of scene displays had a more favorable impact on competence ratings than the use of grid displays. Family caregiver ratings were significantly ( p < .05) more favorable than ratings from other groups. The Communicative Competence Scale was found to be a reliable measure of perceived communicative competence. Scene displays have the potential to enhance the perceived communicative competence of this population.
