Predictors for Augmentative and Alternative Communication Clinical Service Provision: Closing the Gap

Area of Science:

• Speech-Language Pathology
• Augmentative and Alternative Communication (AAC)
• Clinical Practice

Background:

• The human right to communicate is central to speech-language pathologist (SLP) services.
• Augmentative and Alternative Communication (AAC) modalities offer vital communication support.
• Translating AAC knowledge into clinical practice remains a significant challenge for SLPs.

Purpose of the Study:

• To investigate factors influencing the provision of AAC clinical services.
• To understand the importance of variables impacting AAC service delivery by SLPs.

Main Methods:

• Survey data from 530 SLPs in the United States on AAC practices, barriers, and professional development.
• Hierarchical multiple regression to analyze knowledge and AAC use.
• Binomial logistic regression to predict barriers and learning preferences.

Main Results:

• Clinical practicum experiences significantly impact SLPs' knowledge and barriers in AAC practice.
• Continuing education (CE) in AAC is the primary driver for AAC service provision.
• Barriers to AAC provision are linked to clinical practicum, patient load, and geographic region.

Conclusions:

• Hands-on clinical practicum is crucial for overcoming AAC service barriers and fostering collaboration.
• Evidence-based professional development effectively translates AAC knowledge into clinical practice.
• High-quality professional development is essential for addressing the knowledge-practice gap in AAC.
