Documenting changes in speech intelligibility across time is an important but difficult task for speech-language pathologists. This study reports on the development and initial testing of the Preschool Speech Intelligibility Measure (PSIM), a single-word, multiple-choice intelligibility measure. The PSIM is adapted from the Assessment of Intelligibility of Dysarthric Speech (Yorkston & Beukelman, 1981) and is designed to plot changes in children’s speech intelligibility across time. This instrument is offered as an addition to the existing array of available speech intelligibility measures.
