Interrater Reliability and Concurrent Validity for the Apraxia of Speech Rating Scale 3.0: Application With Persons With Acquired Apraxia of Speech and Aphasia

Wambaugh et al. | 2019

— Purpose —

To provide interrater reliability and concurrent validity data to the Apraxia of Speech Rating Scale (ASRS) 3.0 for people with AOS and aphasia to consider if it is a good tool for determining AOS presence and severity.

— Findings —

Authors found ASRS 3.0 to be a good tool with strong interrater reliability and concurrent validity (as based on clinicians using the tool with no prior experience using it). ASRS 3.0 was used to rate samples from Assessment of Intelligibility of Dysarthric Speech (ASSIDS) and the “Duffy Protocol” (from Duffy, 2013 p.83), with the N&B 5-Item Discourse Assessment (from Nicholas & Brookshire, 1994, Set A) used for those with aphasia. “There were moderate to strong negative correlations between intelligibility ratings and total ASRS 3.0 scores.”
