Summary
Speech-language pathologists in Thailand prefer iPad-based augmentative and alternative communication (AAC) systems for children with complex communication needs. Gestural communication was found easiest to learn and use, despite high acceptance of AAC technologies.
Area of Science:
- Speech-Language Pathology
- Assistive Technology
- Communication Sciences
Background:
- Augmentative and alternative communication (AAC) systems are underutilized in Thailand.
- Understanding speech-language pathologists' (SLPs) perceptions is crucial for introducing AAC interventions to children with complex communication needs.
- This study addresses the need to assess perceptions of different AAC modalities among Thai SLPs.
Purpose of the Study:
- To assess Thai SLPs' perceptions of three AAC modalities: gestural communication, communication boards, and iPad-based speech-output technologies.
- To understand SLPs' ratings on intelligibility, learnability, usability, effectiveness, and preference for each AAC mode.
- To explore SLPs' rationales and preferences for AAC modalities for nonverbal clients and for personal use.
Main Methods:
- A quantitative study involving 78 speech-language pathologists (SLPs) in Thailand.
- Participants viewed video vignettes of a child using gestural communication, communication boards, and iPad-based speech-output technologies.
- SLPs rated each modality on intelligibility, ease of use, effectiveness, and preference using rating scales and visual analog scales.
Main Results:
- iPad-based speech-output technologies were rated as the most intelligible, effective, and preferred AAC modality by SLPs.
- Gestural communication was perceived as the easiest modality for children to learn and use.
- Despite limited current use, iPad-based AAC showed high social acceptance among SLPs for promoting communication in children with complex needs.
Conclusions:
- Thai SLPs demonstrate a preference for iPad-based speech-output technologies, indicating high social acceptance for this AAC modality.
- Gestural communication is recognized for its ease of learning and use in pediatric populations.
- Findings highlight potential biases and knowledge gaps regarding AAC systems within Thailand that require further attention.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

The barriers to effective communication also include cultural barriers, semantic barriers, gender barriers, and time constraints.
Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
