Abstract:
Background: Diagnostic accuracy and reliability of acquired apraxia of speech (AOS) in the presence of co-occurring aphasia and/or dysarthria is crucial for appropriate treatment selection and clinical decision making. However, overlapping symptomology and lack of operationalization of AOS assessment methods have contributed to inadequate interrater reliability of perceptual measures differentially diagnostic of AOS. Purpose: This study investigated factors influencing the operationalization of AOS assessment methods, primarily interrater reliability of perceptual characteristics of differentially diagnostic (i.e., phonetic and prosodic errors) measures in order to inform assessment methods in AOS with concomitant aphasia. In addition, several other factors influencing the operationalization of AOS assessment methods were explored including: the utility of a pre-existing stimulus readily available in a standardized aphasia assessment (WAB-R), interrater reliability of non-discriminatory characteristics of ...
