The purpose of the current study was to examine whether seven children, aged 6–10 years, with intellectual disabilities who require augmentative and alternative communication, could acquire ...phonological awareness and reading skills by using a reading material that is based on research on the evidence-based reading program Accessible literacy learning. The effect of the measures has been examined using a multiple single-case design with baseline, posttest, follow-up, and maintenance. All the teachers were trained to deliver the reading intervention in the students’ familiar place at school. The results indicated that students with intellectual disabilities who require augmentative and alternative communication could acquire phonological awareness and decoding by working systematically with reading material based on evidence-based strategies.
•Students with intellectual disabilities who use AAC can acquire reading skills.•Combining several reading components together with systematic and explicit teaching gives best effect acquiring reading skills.
Autism is both a medical condition that gives rise to disability and an example of human variation that is characterised by neurological and cognitive differences. The goal of evidence-based ...intervention and support is to alleviate distress, improve adaptation, and promote wellbeing. Support should be collaborative, with autistic individuals, families, and service providers taking a shared decision-making approach to maximise the individual's potential, minimise barriers, and optimise the person–environment fit. Comprehensive, naturalistic early intervention with active caregiver involvement can facilitate early social communication, adaptive functioning, and cognitive development; targeted intervention can help to enhance social skills and aspects of cognition. Augmentative and alternative communication interventions show preliminary evidence of benefit in minimising communication barriers. Co-occurring health issues, such as epilepsy and other neurodevelopmental disorders, sleep problems, and mental health challenges, should be treated in a timely fashion. The creation of autism-friendly contexts is best achieved by supporting families, reducing stigma, enhancing peer understanding, promoting inclusion in education, the community, and at work, and through advocacy.
For early symbolic communicators, acquisition of an initial vocabulary is a critically important achievement that sets the stage for future language development. Children who require augmentative and ...alternative communication (AAC) rely on others to select and provide these important first words for them. One resource to help guide this process includes published lists of words that may contribute to a core vocabulary for individuals who require AAC. Although some clinicians report that they consider or prioritize core words during the vocabulary selection process, it is not known whether an emphasis on core words will best meet the expressive vocabulary needs of early symbolic communicators. The purposes of this narrative review were to (a) review studies that have developed word lists to inform selection of a core vocabulary for young children who require AAC, (b) compare the words on these lists to the early words used by children with typical development, and (c) consider the implications for vocabulary selection and language development for early symbolic communicators who require AAC. Results suggest that core word lists may under-emphasize many of the types of words that predominate in early expressive vocabulary; these lists may not be the most appropriate resources to guide AAC system design and instruction for early symbolic communicators.
Earlier research shows an arrest in reading and writing development among 9-12-year-old students with severe speech and physical impairment, SSPI. This article explores what five students with SSPI ...who have reached beyond beginner's phase without arrest in their literacy development have experienced as significant for their reading and writing development. The research design was explorative and case based. It contained researcher-participant longitudinal dialogues focusing on the students' experiences of literacy learning. Computer assisted email interviews were used. A semi-structured interview manual guided each dialogue. With the use of augmentative and alternative communication (AAC) systems and assistive technology devices, the participants could read and write (with alphabetical print in Swedish) independently. The analysis revealed four themes of great importance for the students' development of alphabetical print literacy skills: assistive technology use in writing and reading, continuity in long-term pedagogical relationships, mutual persistence in communication, and visions of nearer goals and future work life. The results are discussed in relation to the theoretical frameworks of self-efficacy and the capability approach.
The present study investigated the relationship between lexicon and grammar in individuals who use graphic symbol-based aided augmentative and alternative communication (AAC). Data came from 60 ...transcripts of generalization sessions that were part of two previous intervention studies, aimed at improving the expressive vocabulary and grammar of 12 children and youth who used graphic symbol-based AAC. The specific aims of the current study were to (a) describe vocabulary composition across different levels of expressive vocabulary and (b) analyze the relationship between global measures of expressive vocabulary and the use of grammar in individuals who use aided AAC. A series of multiple linear mixed effect regression analyses showed a positive predictive association between overall vocabulary size and the use of closed-class words, and a positive relationship between the use of verbs and the use of closed-class words. Additionally, the use of verbs had a significant positive association with the use of inflectional morphology, while the use of nouns did not. Theoretical and practical implications of these findings are discussed.
The aim of this study was to synthesise the evidence concerning communication in critically ill tracheostomy patients dependent on cuff inflation. The aim was to identify the psychological impact on ...patients awake and alert with tracheostomies but unable to speak; strategies utilised to enable communication and facilitators and barriers for the success of these strategies.
This scoping review was conducted using the Joanna Briggs Institute framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.
CINAHL, Embase, Medline, and Web of Science were searched from 1st January 2000 to 30th September 2023 and supplemented with hand searching of references from included studies.
Studies were eligible if they addressed the psychological impact of voicelessness and/or the structure, process, and outcomes of augmentative and alternative communication (AAC) systems, in addition to facilitators and barriers to effectiveness. The population of interest included critically ill tracheostomy patients dependent on cuff inflation, their families, and healthcare workers. Screening and data extraction were undertaken by two reviewers independently. Data analysis involved descriptive statistics and content analysis.
A total of 23 studies met the inclusion criteria: 11 were qualitative, nine were quantitative, and three were mixed-methods studies. Voicelessness elicited negative emotions, predominantly frustration. AAC systems, encompassing unaided and aided (low-tech and high-tech) methods, presented both advantages and drawbacks. High-tech strategies held promise for patients with physical limitations. Patients equally appreciated the support offered through unaided strategies, including eye contact and touch. Facilitating factors included speech therapy involvement and assessment. Patient-related challenges were the most frequent barriers.
Facilitating meaningful communication for critically ill tracheostomy patients dependent on cuff inflation is of paramount psychological significance. Whilst AAC systems are practicable, they are not without limitations, implying the absence of a universally applicable solution. This underscores the importance of continuous evaluation, reinforced by a multidisciplinary team.

Amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease, restricts patients’ communication capacity a few years after onset. A proof-of-concept of brain–computer interface (BCI) ...has shown promise in ALS and “locked-in” patients, mostly in pre-clinical studies or with only a few patients, but performance was estimated not high enough to support adoption by people with physical limitation of speech. Here, we evaluated a visual BCI device in a clinical study to determine whether disabled people with multiple deficiencies related to ALS would be able to use BCI to communicate in a daily environment.
After clinical evaluation of physical, cognitive and language capacities, 20 patients with ALS were included. The P300 speller BCI system consisted of electroencephalography acquisition connected to real-time processing software and separate keyboard-display control software. It was equipped with original features such as optimal stopping of flashes and word prediction. The study consisted of two 3-block sessions (copy spelling, free spelling and free use) with the system in several modes of operation to evaluate its usability in terms of effectiveness, efficiency and satisfaction.
The system was effective in that all participants successfully achieved all spelling tasks and was efficient in that 65% of participants selected more than 95% of the correct symbols. The mean number of correct symbols selected per minute ranged from 3.6 (without word prediction) to 5.04 (with word prediction). Participants expressed satisfaction: the mean score was 8.7 on a 10-point visual analog scale assessing comfort, ease of use and utility. Patients quickly learned how to operate the system, which did not require much learning effort.
With its word prediction and optimal stopping of flashes, which improves information transfer rate, the BCI system may be competitive with alternative communication systems such as eye-trackers. Remaining requirements to improve the device for suitable ergonomic use are in progress.
To systematically evaluate the acceptability of high-technology augmentative and alternative communication (high-tech AAC) among ICU patients who are voiceless guided by the technology acceptance ...model (TAM).
We searched the Cochrane Library, EMBASE, PubMed, CINAHL, PsycINFO, Web of Science, SinoMed, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database and Wanfang Database from database inception to September 2019. Studies that examined conscious nonverbal ICU patients with high-tech AAC intervention were included. Two reviewers independently collected and evaluated all the studies. The methodological quality was assessed by using the Joanna Briggs Institute critical appraisal tool.
Eighteen studies with a total of 914 patients met the inclusion criteria, and the quality of the studies varied from low to moderate. Based on the TAM, ICU voiceless patients perceived that high-tech AAC was useful, was easy to use, decreased communication difficulties, reduced negative emotions, and improved symptom identification and management. Patients maintained a positive attitude and were willing to continue to use high-tech AAC.
Although the existing evidence is limited, voiceless patients regard high-tech AAC devices as a useful, reliable, and acceptable alternative communication choice in the ICU. Multicenter, large-sample, and high-quality studies are highly recommended in the future.
There is a need for more knowledge about how to enhance children’s participation in the assessment process when applying for support in accordance with the Swedish Disability Act (SDA). Here, ...Augmentative and Alternative Communication (AAC) has been highlighted as a successful way of letting children have a say in matters that concern their everyday lives. This study examines, from social workers’ perspectives, how increased participation can be made possible for children with disabilities during the process of decision-making and planning for support. Based on focus group interviews (N = 17) and individual interviews (N = 11) the findings reveal that the social worker shows a readiness to listen to children’s voices. However, they experience a range of both facilitating, but predominantly complicating, factors when meeting with the child and their parents. It is argued that the social workers’ professional discretion to some extent is influenced by the prevailing organisational culture, where a permissive work climate and proactive leadership are attributed great importance.
This simulation study assessed the ability of Speech-Output Technologies (SOTs) to keep in-time during conversational repair. Fifty-eight Other Initiated Repair (OIR) initiators were collected from ...transcripts of repair interaction sequences collected from past research. A range of selection latencies were then used to calculate simulated utterance composition delays for the OIR initiators using two popular SOT software apps, with and without the use of word prediction. To determine whether OIR utterances could be produced within a socially sensitive temporal gap, composition delay was compared to a conservative temporal limit obtained for oral communicators (Kendrick, 2015). Even at the fastest 0.5 s selection latency level, utterance-level composition delays for both SOTs were substantially greater than the OIR limit set for this study. Next, AAC production rate data spanning a variety of technologies, access methods, tasks and user profiles was obtained from the literature. Communication performance for these groups was then evaluated against the identified temporal OIR limit. None of the user groups were found to be capable of producing full OIR utterances within the temporal limits of oral-speech conversation, with most unable to type even a single selection within these bounds. Because of the frequency and importance of repair in conversation, these results have important implications for designing devices to enable their users to successfully engage in such important conversational activities.
