Abstract

This review article examines the interrater reliability and validity of the Apraxia of Speech Rating Scale (ASRS-3.5) as a valuable tool for evaluating the presence and severity of apraxia of speech (AOS) and its significant features. The study involved assessing the ASRS-3.5 with a cohort of participants, analyzing item responses, correlations, and regression models to establish its accuracy in identifying AOS in individuals with neurodegenerative disease. The findings suggest that the ASRS-3.5 is a reliable and valid scale that demonstrates excellent sensitivity and specificity to AOS presence, making it a promising tool for clinicians in accurately assessing and managing AOS in affected individuals.
