The Impact of Telehealth on the Efficacy of Sound Production Treatment.

Purpose: This investigation was designed to systematically examine the acquisition, maintenance, and response generalization effects of Sound Production Treatment (SPT) delivered via telehealth in comparison to existing in-person outcomes for SPT.

Method: A multiple-baseline design across behaviors and participants was used with two individuals with chronic apraxia of speech (AOS) and aphasia. Accuracy of target speech sounds in treated and untreated words within phrases served as the dependent variable.

The Outcomes of Remote Administration of Combined Aphasia and Apraxia of Speech Treatment: A Single-Subject Experimental Design Study.

Purpose: This study was designed to examine the outcomes of Combined Aphasia and Apraxia of Speech Treatment (CAAST) administered remotely in terms of acquisition and generalization effects and to compare these effects to previous in-person CAAST studies and Response Elaboration Training (RET)/Modified-Response Elaboration Training (M-RET) benchmarks.

Method: Multiple probe designs across participants and behaviors were employed with three speakers with chronic aphasia and apraxia of speech. Correct information units (CIUs) were the primary outcome measure to measure changes in language production.

Reproducibility in Small- Treatment Research: A Tutorial Using Examples From Aphasiology.

Purpose: Small- studies are the dominant study design supporting evidence-based interventions in communication science and disorders, including treatments for aphasia and related disorders. However, there is little guidance for conducting reproducible analyses or selecting appropriate effect sizes in small- studies, which has implications for scientific review, rigor, and replication. This tutorial aims to (a) demonstrate how to conduct reproducible analyses using effect sizes common to research in aphasia and related disorders and (b) provide a conceptual discussion to improve the reader's understanding of these effect sizes.

Sound Production Treatment for Acquired Apraxia of Speech: An Examination of Dosage in Relation to Probe Performance.

Purpose This study was designed to examine the association of dosage and effects of Sound Production Treatment (SPT) for acquired apraxia of speech. Method Treatment logs and probe data from 20 speakers with apraxia of speech and aphasia were submitted to a retrospective analysis. The number of treatment sessions and teaching episodes was examined relative to (a) change in articulation accuracy above baseline performance, (b) mastery of production, and (c) maintenance.
