Abstract
In this study, we share the development of the Peer-Peer Assessment of Speech Intelligibility (PPASI), a child-friendly short form measure of single-word intelligibility based on the Preschool Speech Intelligibility Measure (PSIM; Morris, Wilcox, & Schooling, 1995) and created to equip future researchers to address the lack of empirical evidence indicating how well children understand their peers with Speech-Sound Disorders (SSDS). In the current study, we investigated the concurrent validity of the PPASI relative to the PSIM. Thirteen adult participants completed the PPASI and PSIM for two speech samples, one taken from a child with a diagnosed SSD and the other identified as having developmentally appropriate speech. Findings revealed a strong correlation between the two measures and evidence of the equivalence of scores obtained using the two measures, suggesting that the PPASI demonstrates concurrent validity with the PSIM. Continued development of the PPASI is warranted based upon the findings of the current study.
