New Research Highlights Effective AAC Strategies and Persistent Disparities for Nonspeaking Autistic Individuals

What is AAC?

Augmentative and Alternative Communication (AAC) encompasses tools and strategies to support communication for nonspeaking individuals. This ranges from low-tech options like picture exchange systems (PECS) to high-tech speech-generating devices (examples).

Remote AAC Delivery Shows Promise (With Caveats)

A 2024 RCT in JSLHR (N=24) found telehealth delivery of low-tech picture books matched in-person effectiveness. While promising for underserved areas, this small study didn't assess high-tech devices.

Racial Disparities in AAC Access

A Newswise-reported survey found 84% of white vs. 32% of non-white families had AAC access. Families can request evaluations through school districts or clinics (ASAN guidance).

Classroom Implementation Matters

A 2023 observational study found structured activities increased engagement with speech-generating devices. Parents can advocate for dedicated AAC time in IEP meetings.

Stimming as Communication

A case study in Frontiers (3 dyads) suggested engaging with a child's repetitive movements (stimming) may create communication opportunities.

Peer Support Strategies

A Frontiers perspective piece proposed training classmates to support AAC use, though more research is needed.

Consensus on AAC Benefits

Decades of research support AAC's benefits without impeding speech development (PMC review). Major organizations reject facilitated communication due to facilitator influence concerns (ASHA letter).
