Communication Partner Engagement: A Relevant Factor for Functional Outcomes in Speech-Language Therapy for Aphasic...

Area of Science:

• Neurology
• Speech-Language Pathology
• Telemedicine

Background:

• Previous reports confirmed the feasibility of telehealth for speech-language therapy in primary progressive aphasia (PPA).
• This study expands on prior work by examining a larger PPA cohort and identifying factors influencing intervention outcomes.

Purpose of the Study:

• To assess the feasibility and outcomes of an 8-session telehealth speech-language intervention for individuals with PPA.
• To explore the impact of post-intervention "check-in" sessions and communication partner engagement on communication confidence.

Main Methods:

• An 8-session internet-based speech-language therapy intervention was delivered to PPA participants and their communication partners.
• Participants were evaluated at baseline, 2 months, and 6 months post-intervention.
• Statistical analyses examined changes in communication confidence and the influence of check-in sessions and partner engagement.

Main Results:

• Communication confidence significantly improved by the 2-month evaluation and was maintained at 6 months.
• Improvements were observed across various communication contexts.
• Sustained gains in communication confidence were associated with engaged communication partners, not with additional check-in sessions.

Conclusions:

• Internet-based, person-centered speech-language therapy is a promising model for individuals with PPA.
• Intervention effects can be maintained for at least 6 months.
• Dyadic interventions involving engaged communication partners enhance and sustain functional communication outcomes.
