Speech-Language Pathologists' Approach to Alternative Access for Augmentative and Alternative Communication for...

Area of Science:

• Speech-language pathology
• Augmentative and Alternative Communication (AAC)
• Pediatric motor impairments

Background:

• Children with motor impairments require specialized Augmentative and Alternative Communication (AAC) assessments.
• Effective AAC system fit is crucial for vulnerable populations.
• Existing literature lacks guidance on the practical assessment process.

Purpose of the Study:

• To investigate the processes speech-language pathologists (SLPs) employ during AAC assessments for children with motor impairments.
• To provide evidence-based insights into determining alternative access solutions for AAC devices.
• To understand the practical execution of AAC assessments.

Main Methods:

• Collective case design utilized for in-depth analysis.
• Data collected through interviews and vignette responses from five participating SLPs.
• Within-case analysis followed by cross-case comparison of assessment processes.

Main Results:

• SLPs reported no individually defined process, yet a collective systemization emerged.
• Key elements included a child-centered focus, isolation of motor access skills, and iterative experimentation.
• Recommendations were built through a process of trial and error over time.

Conclusions:

• A shared framework for AAC assessment in children with motor impairments was identified.
• This framework can guide SLPs, particularly those new to complex cases.
• The study highlights the importance of collaborative teaming approaches in supporting these children.
