Key Takeaway
Consider using Augmentative and Alternative Communication (AAC) to reduce stress and improve healthcare compliance.

This narrative review examines the utility of Augmentative and Alternative Communication (AAC) strategies for autistic children and adolescents within healthcare and clinical research settings. The authors synthesize existing literature to determine how these tools impact patient experience and compliance.

The primary finding suggests that AAC aids can reduce stress and anxiety, which may lead to improved adherence to healthcare protocols. However, the review notes a significant gap in the evidence base: no studies were identified that specifically address the role of AAC in enhancing compliance during clinical research procedures for this population.

Clinical application is limited by the low certainty of evidence regarding specific research protocols. While AAC aids may facilitate participation and compliance in healthcare settings, their specific impact on clinical research procedures remains unvalidated by primary trials. Practitioners should consider these tools as potential supports for reducing anxiety while acknowledging the current lack of specialized data.

Navigating healthcare settings can be overwhelming for children and adolescents with autism. The noise, unfamiliar environments, and complex instructions often lead to high levels of stress and anxiety, which can make it difficult for these young people to participate fully in their own care.

Research suggests that Augmentative and Alternative Communication (AAC) strategies can help bridge this gap. These tools provide alternative ways to communicate, which may lower stress levels and improve how well patients follow healthcare protocols. By reducing anxiety, AAC aids can make medical visits more manageable for both the child and the provider.

While these findings are promising for general healthcare settings, there is currently a lack of specific research regarding how AAC tools perform during specialized clinical research procedures. Because of this gap, the evidence for use in research trials specifically is not yet firmly established. However, using these communication aids remains a practical way to support autistic youth in everyday medical environments.

What this means for you:
AAC tools can reduce stress and anxiety for autistic children, helping them better manage healthcare visits.

Common questions

What are AAC tools and how do they help?

Augmentative and Alternative Communication (AAC) refers to methods used to give people with communication challenges a way to express themselves. For autistic children, these tools can reduce stress and anxiety during medical visits. By lowering their stress levels, these aids can make it easier for them to follow healthcare protocols and participate in their care.

Can AAC help kids stay calm at the doctor?

Yes, evidence suggests that AAC tools can lower anxiety and stress for autistic children and adolescents. When these young people feel less stressed, they are more likely to comply with healthcare instructions. This makes the experience of visiting a clinic or hospital much smoother for both the child and the medical staff.

Is there research on using AAC during clinical trials?

Currently, there is no specific evidence regarding how AAC tools perform specifically during clinical research procedures for autistic children. While they are helpful in general healthcare settings to reduce stress, more research is needed to see how they work within specialized clinical research protocols.

Autistic children and adolescents often experience medical and neurocognitive co-occurrences that necessitate regular healthcare monitoring. Language difficulties, often observed in autistic individuals, can impede effective communication and participation in medical settings, potentially reducing treatment compliance. Communication barriers also pose challenges in involving autistic youth in research protocols, such as those including Non-Invasive Brain Stimulation (NIBS). Augmentative and Alternative Communication (AAC) strategies could facilitate the participation of autistic individuals in both healthcare and research settings.This narrative review synthesizes the use of AAC to enhance compliance in healthcare and clinical research contexts for autistic children and adolescents. Findings suggest that AAC aids can reduce stress and anxiety, thereby improving adherence to healthcare protocols. However, no studies were identified that specifically address AAC’s role in enhancing compliance during clinical research procedures involving autistic children and adolescents. Based on the current literature, here we propose a set of AAC aids to improve understanding and compliance with NIBS in autistic individuals.
