RESUMO
BACKGROUND: The evaluation of pain in patients, unable of oral communication, often relies on behavioral assessment. However, some critically ill patients, while non-verbal, are awake and have some potential for self-reporting. The objective was to compare the results of a behavioral pain assessment with self-reporting in awake, non-verbal, critically ill patients unable to use low-tech augmentative and alternative communication tools. METHODS: Prospective cohort study of intubated or tracheotomized adult, ventilated patients with a RASS (Richmond Agitation Sedation Scale) of -1 to + 1 and inadequate non-verbal communication skills in a surgical intensive care unit of a tertiary care university hospital. For pain assessment, the Behavioral Pain Scale (BPS) was used. Self-reporting of pain was achieved by using an eye tracking device to evaluate the Numeric Rating Scale (NRS) and the pain/discomfort item of the EuroQol EQ-5D-5 L (EQ-Pain). All measurements were taken at rest. RESULTS: Data was collected from 75 patients. Neither the NRS nor the EQ-Pain (r < .15) correlated with the BPS. However, NRS and EQ-Pain were significantly correlated (r = .78, p = < 0.001), indicating the reliability of the self-reporting by these patients. Neither the duration of intubation/tracheostomy, nor cause for ICU treatment, nor BPS subcategories had an influence on these results. CONCLUSIONS: Behavioral pain assessment tools in non-verbal patients who are awake and not in delirium appear unreliable in estimating pain during rest. Before a behavioral assessment tool such as the BPS is used, the application of high-tech AACs should be strongly considered.

BACKGROUND: Pictures drawn by people with aphasia (PWA) are often more challenging to understand than those drawn by healthy people. There are two types of objects: those that tend to be drawn symbolically (symbolically drawn objects-SOs) and those that are likely to be drawn realistically (realistically drawn objects-ROs). AIMS: To compare the identification rate and number of misunderstanding types between SOs and ROs drawn by PWA and healthy controls (HCs). To reveal trends in the misunderstandings of drawings by PWA, and to identify the language or cognitive abilities related to the identification rate of pictures drawn by PWA. METHODS & PROCEDURES: We designed a drawing task involving SOs and ROs. A total of 18 PWA and 30 HCs completed the task, and respondents identified the drawings. The identification rate and number of misunderstandings were analysed with two-way analysis of variance (ANOVA) including group (PWA and HCs) and object type (SOs and ROs). The misunderstandings were divided into four categories varying in semantic and morphological similarity; these ratios were examined with a chi-square test. The relationships of language and cognitive abilities with the identification rate were investigated with multiple regression analyses. OUTCOMES & RESULTS: There was a significant effect of the interaction between group and object type on the identification rate (F(1.1387) = 3.90, Mean Squared Error (MSE) = 4139.67, p = 0.04): the identification rates for ROs were lower in the PWA than in the HCs. For the number of misunderstanding types, an interaction was observed between group and object type (F(1.56) = 8.26, MSE = 26.93, p < 0.01): the number of misunderstanding types for ROs in the PWA was greater than that in the HCs. The misunderstanding patterns differed between ROs and SOs (χ2(3) = 694.30, p < 0.001, V = 0.37). ROs were semantically related, whereas SOs were morphologically related. The identification rates of ROs and SOs were correlated only with Kanji writing scores (ROs: ß = 3.66, p = 0.01; SOs: ß = 6.57, p < 0.01). CONCLUSIONS & IMPLICATIONS: In drawings by the PWA, SOs had a higher identification rate, while ROs had a lower identification rate and a greater variety of misunderstandings. SOs may increase drawing motivation. Interventions to improve the identifiability of SOs and ROs should reflect each character. Identification rates were correlated only with Kanji writing scores. The PWA, whose native language was Japanese and had preserved Kanji writing abilities, and their communication abilities may be increased through drawing. WHAT THIS PAPER ADDS: What is already known on the subject PWA often have impaired drawing abilities and draw pictures that third parties misinterpret. Some objects tend to be drawn symbolically, and some are drawn realistically. However, it is not clear whether there is a difference between these types of drawings depicted by PWA in identifiability and the tendency to be misunderstood by ordinary people. In addition, the relationships between language or cognitive abilities and the identification rate of drawn pictures are not clear. What this paper adds to the existing knowledge The identification rate differed between SOs and ROs. In drawings by PWA, SOs had a higher identification rate, while ROs had a lower identification rate and the greatest variety of misunderstandings. Approximately half of the misunderstandings were related to the target object. SOs tended to be confused with morphologically related objects, while ROs tended to be confused with semantically related objects. Identification rates were correlated only with Kanji writing scores. What are the potential or actual clinical implications of this work? To motivate PWA's drawing, it is suitable to begin with SOs. Examining drawing ability from the perspective of SOs and ROs increases the chance of identifying drawing ability. PWA whose native language is Japanese and have preserved Kanji writing abilities may be able to increase their communication abilities through drawing.

BACKGROUND: Over 8 million children with disabilities live in Africa and are candidates for augmentative and alternative communication (AAC), yet formal training for team members, such as speech-language therapists and special education teachers, is extremely limited. Only one university on the continent provides postgraduate degrees in AAC, and other institutions provide only short modules at an undergraduate level. The need for an introductory training course on AAC that is accessible by university students continent-wide was identified. An online programme, namely an intelligent tutoring system (ITS), was identified as a possible option to facilitate interactive learning without the need for synchronous teaching. The use of an ITS is shown to be effective in developing knowledge and clinical reasoning in the health and rehabilitation fields. However, it has not yet been applied to student teaching in the field of AAC. AIM: To determine both the feasibility of an ITS to implement an AAC curriculum for students in four African countries, and the usability and effectiveness of such a system as a mechanism for learning about AAC. METHOD & PROCEDURES: The study included two components: the development of a valid AAC curriculum; and using the ITS to test the effectiveness of implementation in a pre- and post-test design with 98 speech-language therapy and special education students from five universities. OUTCOMES & RESULTS: Statistically significant differences were obtained between pre- and post-test assessments. Students perceived the learning experience as practical, with rich content. CONCLUSIONS & IMPLICATIONS: The findings suggest that the ITS-based AAC curriculum was positively perceived by the students and potentially offers an effective means of providing supplementary AAC training to students, although modifications to the system are still required. WHAT THIS PAPER ADDS: What is already known on the subject Professionals typically lack formal training in AAC. In Africa, this presents a serious challenge as there are over 8 million children who are candidates for AAC. A need for an introductory training course on AAC, which can be accessed by university students continent-wide, was identified. What this paper adds to existing knowledge An AAC curriculum was developed and integrated into an ITS, an online programme allowing interactive learning through asynchronous teaching. Students from four African countries completed the AAC ITS curriculum. The curriculum was positively received by the students and statistically significant changes in knowledge were identified. What are the practical and clinical implications of this work? This feasibility study shows that the use of an ITS is an effective means of providing AAC training to university students in these African countries. The results provide a valuable contribution toward ensuring the equitable distribution of AAC training opportunities in the African context. This will have a significant positive impact on those who are candidates for AAC.
RESUMO
Facilitated communication (FC) has been a heavily debated and documented topic across multiple disciplines, including sociology, education, psychology, pediatrics, speech-language pathology, and disability studies. Although many professionals from various disciplines and advocates have offered opinions, suggestions, and research on the topic, there has been minimal input from the occupational therapy (OT) profession. The lack of OT input is noteworthy as OTs are experts in enabling upper extremity performance and independence through a variety of training, adaptation and modification strategies, and use of external supports. Because of their professional code of ethics and a specific knowledge base, OTs are uniquely positioned to provide a host of ethical and evidence-based strategies that enable independent access to communication technology. The consideration of multiple access options is contrary to the typical facilitated encounter where facilitators exclusively choose to manipulate an upper extremity in order for letters to be selected on a display or keyboard. The purpose of this paper is threefold: (a) To offer insight into the standard of care by OTs including their ethical standards; (b) to identify varied accommodations that enable access using a feature-matching standard of care that eliminates the need for a facilitator; and (c) to highlight how to increase independent assistive technology/augmentative and alternative communication access, thus dissuading the need or use of facilitated access to letters.

Children with complex communication needs often have multiple disabilities including visual impairments that impact their ability to interact with aided augmentative and alternative communication (AAC) systems. Just as the field benefited from a consideration of visual cognitive neuroscience in construction of visual displays, an exploration of psychoacoustics can potentially assist in maximizing the possibilities within AAC systems when the visual channel is either (a) not the primary sensory mode, or (b) is one that can be augmented to ultimately benefit AAC outcomes. The purpose of this paper is to highlight background information about psychoacoustics and present possible future directions for the design of aided AAC system technologies for children with visual impairments who rely on auditory information to learn and utilize AAC.

Since effective and successful AAC service delivery relies on the knowledge and competence of professionals in the field of AAC, sufficient training in AAC will equip professionals to provide quality AAC service delivery. However, many professionals lack training in AAC and structured opportunities for professional development are sorely needed. As there is no consensus on the amount, mode of delivery and content of AAC training, the purpose of this scoping review was to identify AAC training programs for professional development and to describe the characteristics and effects of such programs. A five-pronged search strategy was used to identify relevant studies. The certainty framework was used to appraise the quality of included studies. Charted data included general study characteristics; participant characteristics; training characteristics (i.e., training goals; instructional materials and strategies; training duration); quality appraisal; and reported effects of the training. The scoping review identified 34 studies for inclusion. The results showed the potential of AAC training programs for continuous professional development to increase professionals' skills in AAC intervention. A range of training characteristics was identified to guide the development of future training programs. Gaps in the research related to the training of AAC professionals were also identified to guide future research.
RESUMO
The relationships between the use of nouns and verbs, and other word classes have been well established in the typical language development literature. However, questions remain as to whether the same relationships are seen in the language use of individuals who use graphic symbol-based augmentative and alternative communication (AAC). The aim of the study was to examine relationships between the use of verbs and nouns, and the use of prepositions, adverbs, and adjectives through a secondary analysis of language transcripts taken from 12 children and adolescents who used aided AAC in conversation with an adult. A series of multiple linear mixed-effect regression analyses showed a positive predictive association between the use of verbs and the use of prepositions and adverbs, as well as a positive predictive relationship between the use of nouns and the use of adjectives. The theoretical and practical implications of these findings are discussed.
RESUMO
On February 2 2023, one of the guiding lights in the field of augmentative and alternative communication (AAC) for more than four decades, David E. Yoder, passed away at the age of 90. A voracious reader and gifted storyteller, David was particularly fond of a quote from George Bernard Shaw's Back to Methuselah, "You see things; and you say 'Why?' but I dream things that never were; and I say 'Why not?'" That vision led him to take on multiple leadership roles and influence the field of AAC in multiple ways. He played a pivotal role in establishing both the International Society for Augmentative and Alternative Communication (ISAAC) and the United States Society for Augmentative and Alternative Communication (USSAAC). Additionally, he chaired the panel for the National Institute on Disability and Rehabilitation Research (NIDRR)'s inaugural Consensus Validation Conference on AAC, advocated for the American Speech-Language-Hearing Association to recognize AAC within the profession's scope of practice, and served as the first editor for the Augmentative and Alternative Communication journal. In this tribute, we describe David's diverse and unique contributions to improving the lives of people with communication challenges with a focus on some of his central insights and actions.

Most students with intellectual and communicative disability who rely on augmentative and alternative communication (AAC) attend non-inclusive school settings. Little is known about turn-taking and the use of various communication modes in groups of students and staff in this context. Previous studies on single students with intellectual disability in various school settings have found that staff tend to dominate interactions and augmented communication modes are used more during structured than unstructured activities. The present study explored turn-taking contributions and communication modes in whole groups of students and staff in non-inclusive school settings in Sweden. Video observations of 33 students and 30 school staff were conducted in seven classrooms during one structured activity (circle time) and one unstructured activity (leisure time). Turn-taking contributions and communication modes were examined when comparing students and staff and when comparing the two activities. Findings revealed that staff dominated the interactions and augmented communication modes were used less during leisure time than circle time. Notably, aided augmented communication modes, particularly speech-output technologies, were used sparsely. Findings of this study highlight the importance of supporting staff members in applying partner strategies and incorporating augmented input, especially aided augmented input, across various group activities at school.

Sharing personal stories with others is essential to human interaction and language development. To communicate, individuals use a variety of semiotic resources, including images, symbols, and written and spoken language. These modes are deployed in the co-construction of a daily face-to-face conversation. A self-created film can serve as a valuable resource to facilitate a deeper understanding of a personal experience, especially where spoken or written language may present a challenge, for example, for people who rely on augmentative and alternative communication (AAC). Although the AAC literature indicates that using videos delivers benefits for aided communicators, guidelines on how to self-create, use, and transcribe them are rare. The present paper, a tutorial, describes how people who use AAC can develop a personal-video-scene (PVS) via the Film as Observable Communication (FaOC) method to utilize self-created films in sharing their stories. The first part of this paper, the theoretical framework, describes theories, methods, and practices from the fields of AAC, social semiotics, and visual anthropology, on which the FaOC method is based. The second part provides a step-by-step tutorial delivering practical guidance on how to create, use, and transcribe the PVS as a resource in conversations.
RESUMO
Communication accessibility has been defined by many scholars and organizations, but it is generally described as clear communication that everyone can access and understand. The objective of this manuscript was to assess communication accessibility for people who use augmentative and alternative communication (AAC) within a variety of restaurant settings through interviewing five adults who utilize AAC as their primary form of communication. Interviews were qualitatively coded and revealed common communication accessibility themes restaurants and restaurant staff were not implementing, such as direct communication and increasing AAC awareness. The implications of the interview data include its potential usage in training restaurant staff and management to utilize communication accessibility tips and features to increase the communication accessibility of the restaurant patrons they serve, especially for individuals who use AAC. This could then lead researchers in creating a formal training schema for restaurants to implement into their businesses reliably and effectively.
RESUMO
The selection of appropriate vocabulary is a crucial and challenging aspect of augmentative and alternative communication (AAC) intervention. Core vocabulary lists are frequently used to support vocabulary selection for children who require AAC. A vocabulary domain that has garnered limited attention within the AAC literature is relational basic concepts (RBCs). RBCs describe relationships between objects, persons, or situations, and play a pivotal role in language development, communication, and academic success. For the present study, we created a list of 156 RBCs, drawing primarily from assessments that measure basic concept knowledge in preschool and early elementary school students. We examined the overlap of these words on nine core vocabulary lists. We found that most concepts were not represented on any core lists. Additionally, there was relatively little overlap of RBCs between the core lists. These findings suggest that vocabulary selection resources created using exclusively a core vocabulary approach may have limited utility for identifying many concepts that preschool and early elementary students are expected to know and use. Implications for AAC research and practice are discussed with emphasis on the need for further consideration of RBCs within vocabulary selection practice and the field of AAC at large.
RESUMO
The current study explored both the extent to which representation of augmentative and alternative communication (AAC) exists in young adult literature, as well as qualitative characteristics of that representation. A systematic search of multiple databases was conducted using standardized keywords and inclusion criteria. Descriptive statistics and literary content analysis were employed in order to analyze quantitative and qualitative information about each of the 32 novels that fit inclusion criteria. Results indicated that, while representation of AAC in young adult fiction largely aligned with existing statistics regarding types of AAC devices used, stories often differed from current information about the most common etiologies of AAC users. Analyses of character development revealed most featured AAC-using characters were multidimensional and expressed positive attitudes regarding their devices, although some characters also expressed frustration. These results indicated that representation of AAC in young adult literature was sparse. However, the representation that did exist at least partially reflected reality and may represent a positive portrayal of AAC use and users.
RESUMO
The aim of this interpretive qualitative study was to explore how environmental factors influence the transition from relying solely on graphic symbols to using spelling in face-to-face communicative interactions, from the perspective of literate adults with speech and motor impairments who use augmentative and alternative communication (AAC). Fourteen adults either chose to submit a written story with weekly email follow-up, took part in interviews conducted via Zoom1, or chose to communicate solely by email. Researchers analyzed data using Charmaz's (2014) constructivist grounded theory approach. The analysis yielded three themes explaining environmental factors relevant to the transition from using graphic symbols to spelling in communication: (a) access to AAC systems and services; (b) knowledgeable and supportive communication partners who have high expectations; and (c) opportunities to learn reading, writing, and spelling. Supportive factors included providing sufficient time for spelling in communicative interactions, structured learning opportunities for practice and independence, opportunities to learn through socially meaningful interactions and having print-rich and language-rich activity settings. Slow speed in navigating graphic symbols and lack of ability to express an exact message were motivational reasons for participants to use spelling in communicative interactions. The interaction among environmental factors and person-related characteristics warrants further investigation.
RESUMO
The Picture Exchange Communication System (PECS) is a popular augmentative and alternative communication intervention for individuals with developmental disabilities that includes six, sequential phases of instruction. We systematically reviewed published and unpublished single-case PECS studies for details about the percentage of participants mastering PECS phases, how long it took participants to master PECS phases (in trials to mastery), and what constituted mastery of PECS phases. We found most participants mastered only the first two phases of PECS, and Phases I, II, and IV showed the slowest and widest variability in trials to mastery. Moreover, participants who were taught the third PECS phase learned to select from an average array of three symbols, which may limit the range of messages they can communicate. We discuss our findings in light of a few important limitations and provide directions for future researchers along with recommendations for professionals who might consider PECS.

Key word signing (KWS) is an unaided form of augmentative and alternative communication (AAC) and is frequently used by children with cognitive impairments and their families. Successful implementation of KWS requires a family environment that provides aided language input by modeling the signs. However, families face challenges implementing the signs in their everyday lives. KWS requires effort and sustained parental commitment. Users may also struggle with finding good learning resources and stimulating and enjoyable shared contexts for communication. Signed videos of popular children's books may help to implement KWS and create a signing environment which exposes children and their families to KWS in meaningful ways. The aim of this study was to create videos of this type and investigate whether and how they might serve as an attractive medium of support for families' KWS experience. Three families tested the videos. A triangulated qualitative study incorporating interviews and participant observation explored the families' experience of using these videos as a context for shared communication. The findings suggest that picture book videos supplemented by KWS may be appropriate resources for the use of KWS in everyday family life. They serve as a child-centered activity involving KWS exposure, in which children and their families can participate joyfully and naturally.
RESUMO
Individuals with multiple disabilities are among the most challenging to serve and AAC teams often lack direction in determining effective interventions. The purpose of this scoping review was to summarize the research evidence on AAC interventions for individuals with complex communication needs and simultaneous motor, and visual impairments as part of their multiple disabilities; to consider implications for practice; and to determine gaps and directions for future research. A total of 27 studies were identified and reviewed, involving 55 unique participants with multiple disabilities. Most studies focused on direct intervention to increase requesting or choice-making, with little focus on social communication. Only two studies focused on training communication partners. Results indicated that AAC interventions can be highly effective to increase communication for individuals with multiple disabilities. However, there is an urgent need for increased rigor and more detailed participant information in future AAC intervention research with this population. Future research should investigate AAC intervention to improve social communication and increase language development, not just expression of needs and wants. Future research should focus on the needs of individuals with multiple disabilities from culturally and linguistically diverse backgrounds and on implementation of AAC within natural environments.

Parent training programs aimed at improving language outcomes for children with complex communication needs have predominantly been evaluated on child-centered outcomes and less often on the impact on social life or parental well-being. This study examined parent perceptions of social life before and after ComAlong, a group intervention providing parents with knowledge and training in responsive communication, environmental-milieu teaching strategies and augmentative and alternative communication (AAC). Parents (N = 467) completed questionnaires during the first and last sessions of ComAlong groups held in Sweden 2012 to 2018. Main outcome measure was change in the Social Life Scale from the Family Impact Questionnaire. Associations between this measure and demographic factors of parents and children were analyzed, along with reported change in parents' use of AAC. Pre-post comparisons revealed small significant positive changes in perceived impact of social life following intervention. The magnitude of the positive change was larger among parents of children with non-syndromic diagnoses and parents of children with autism spectrum disorder or attention deficit hyper activity disorder (ADHD). Differences in social life impact was not associated with parents' gender, language proficiency, age, or educational background. In conclusion, communication-focused parent training programs can have a positive impact on social family life and may thereby influence children's participation.

It is well-known that children with expressive communication difficulties have the right to communicate, but they should also have the right to do so in whichever language they choose, with a voice that closely matches their age, gender, and dialect. This study aimed to develop naturalistic synthetic child speech, matching the vocal identity of three children with expressive communication difficulties, using Tacotron 2, for three under-resourced South African languages, namely South African English (SAE), Afrikaans, and isiXhosa. Due to the scarcity of child speech corpora, 2 hours of child speech data per child was collected from three 11- to 12-year-old children. Two adult models were used to "warm start" the child speech synthesis. To determine the naturalness of the synthetic voices, 124 listeners participated in a mean opinion score survey (Likert Score) and optionally gave qualitative feedback. Despite limited training data used in this study, we successfully developed a synthesized child voice of adequate quality in each language. This study highlights that with recent technological advancements, it is possible to develop synthetic child speech that matches the vocal identity of a child with expressive communication difficulties in different under-resourced languages.
RESUMO
This qualitative study aimed to describe speech-language pathologists' (SLPs') perspectives on augmentative and alternative communication (AAC) use for people with post-stroke aphasia focusing on: (a) current AAC practice, (b) factors that influence the use of AAC, and (c) the success and relevance of AAC interventions. Semi-structured interviews took place with ten South African SLPs with experience in aphasia intervention. The transcribed interviews were thematically analyzed using a six-phase process of inductive and deductive analysis within a phenomenological framework. All the participants use AAC with their clients, employing a variety of approaches that reflect their diverse settings, experiences, and perspectives on AAC. AAC use is complex, and SLPs make conscious choices considering multiple factors. Barriers to use were often associated with limited resources in the low- and middle-income country (LMIC) context, but most participants retained a positive view of AAC, actively working to circumvent barriers to use. Participants consistently emphasized the vital role of partners in communication interactions, linked to the importance of defining AAC broadly. It is necessary to advance the integration of AAC into rehabilitation plans to improve communication and social participation outcomes for people with post-stroke aphasia, especially in LMICs such as South Africa.
