Early Intervention and AAC: What a Difference 30 Years Makes

A Systematic review of AAC interventions using speech generating devices for autistic preschoolers

Many autistic1 children experience communication challenges. Augmentative and alternative communication (AAC) can function as a primary or supportive mode of communication, and interventions incorporating AAC have a positive impact on the communication skills of autistic children. This systematic review investigated intervention studies using speech generating devices to enhance the expressive language of autistic preschoolers. Specifically, research questions addressed the (a) expressive communication skills and functions; (b) instructional strategies; (c) impact of interventions; and (d) ecological validity of the included studies. After an extensive search process, twenty studies from 1998 to 2023 met the inclusion criteria. Study characteristics were extracted, social and ecological validity were evaluated, and results were described using effect sizes and visual analysis. The majority targeted requesting (n=14) and the remaining addressed communication acts across diverse functions (n=6). Eleven of the studies demonstrated moderate to strong effects. Most interventions were multicomponent, including a variety of strategies, with prompting being the most common. Fewer than half of the studies met the full criteria for ecological validity, and only seven measured social validity. Implications for the field are provided including a call to action for researchers to evaluate interventions to support communication across diverse functions.

Process evaluation of a complex intervention in augmentative and alternative communication care in Germany: a mixed methods study

BACKGROUND

In Germany, clear care pathways for people without natural speech who require augmentative and alternative communication (AAC) are currently lacking. Therefore, AAC is often not sustainably implemented in everyday life. For this reason, a complex intervention was developed that supplements existing AAC consultation with additional AAC training, AAC therapy, and case management. This article presents the results of the process evaluation of the complex intervention. It examines (1) how caregivers and AAC consultants rate the intervention (2), which contextual factors influence its implementation, and (3) the acceptance, use competence, and use of the new AAC system.

METHODS

The process evaluation used a mixed methods design. Quantitative data were collected with a longitudinal survey of caregivers of AAC users in the intervention and comparison groups at three time points (T0: after AAC consultation; T1: 4 weeks after AAC system receipt; T2: 4 months after AAC system receipt). Semi-structured focus group interviews were conducted with caregivers of AAC users and with AAC consultants. The quantitative data were analysed descriptively and with nonparametric mean value comparisons. The qualitative results were analysed using structured qualitative content analysis.

RESULTS

The evaluation and presentation of results were based on the Medical Research Council process evaluation guidance by Moore et al. The intervention elements were rated positively. AAC training and therapy enabled the participants to use the AAC system effectively in different contexts. Case management provided support, particularly in the event of problems in the care process. However, the results also show the heterogeneity of the intervention, as it depended on various contextual factors. Overall, acceptance, use competence, and use of the AAC system were rated higher in the intervention group than in the comparison group.

CONCLUSIONS

The process evaluation illustrates various contextual factors that can influence the implementation of the AAC intervention. The results highlight the potential of the intervention to improve AAC care and establish a sustainable use of AAC systems in everyday life. In addition, the process evaluation provides indications of how AAC interventions can be adapted for successful implementation.

Assessment of Cognition and Language Using Alternative Response Modalities

Assessing cognition and language using standardized tests is challenging when the individual has severe speech and motor impairments. Tests with a multiple-choice format may be adapted without compromising standardization using alternative response modes like partner assisted scanning (PAS) and eye-pointing (EP). Standardization of such assessment is little researched. The study investigates the (a) reliability of, (b) transparency of, and (c) adherence to assessment protocols using PAS and EP. The participants were students from special needs education and speech and language therapy, who worked in dyads (n = 39). Two observers recorded a number of errors made in protocol delivery, independently of each other. The dyads made between 0 and 81.5 errors. Number of errors was not related to response mode, t(38) = -0.21, p = .839. The observers were in high agreement, with an intraclass correlation coefficient of .97, p < .001. The study suggests that assessing language involving alternative modes of responding can be successfully taught to novice practitioners.

The feasibility of just-in-time programming of visual scene displays on mobile technology in AAC intervention for adult beginning communicators

Adults with severe intellectual and developmental disabilities who are beginning communicators can benefit from augmentative and alternative communication (AAC) intervention. The purpose of the current study was to investigate the efficacy of just-in-time programming of visual scene displays during ongoing interactions in an AAC intervention with adults who were beginning communicators. A single subject multiple probe design across four adult participants (ages 29-48) was used to evaluate the intervention. The intervention consisted of the creation of visual scene displays on a tablet computer while engaging the participants with songs, books, and games using just-in-time programming during the activities. Participants completed a minimum of five baseline and five intervention sessions. All participants demonstrated an increase in intentional and conventional communication turns during social interaction when the intervention was implemented. None of the participants discontinued using other intentional and conventional communication modes upon introduction to the tablet system. This intervention approach holds promise for adults with severe disabilities who remain at a beginning communicator level in young and middle adulthood. It is never too late for AAC intervention for any individual.

Increasing linguistic and prelinguistic communication for social closeness during naturalistic AAC instruction with young children on the autism spectrum

This study examined the effects of an intervention package using high-tech augmentative and alternative communication (AAC) with Naturalistic Instruction (NI), time delay, and prompting during social routines for preschoolers on the autism spectrum. The AAC was a communication application on a tablet programmed with color photo representations of participants and communication partners engaged in social routines. The primary dependent measure was a linguistic communication turn on the AAC device completing the instructor's cloze phrase related to the routine. A secondary dependent measure was prelinguistic communication -nonspecific vocalizations and smiling - within each turn of the routine. Results indicated that all communication types increased and maintained for all three participants with two participants meeting mastery criteria within the minimal number of sessions. These results are significant in providing additional evidence for the effectiveness of AAC intervention beyond teaching simple object requests and in teaching more socially meaningful communication to children on the autism spectrum. Additionally, this study supports the use of color photo representations to promote social interaction. Future research should continue to evaluate such interventions on a larger scale and include naturally occurring communication partners, such as siblings and peers.

Reading instruction for students with intellectual disabilities who require augmentative and alternative communication: A multiple single case study with baseline, posttest, follow-up, and maintenance

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.

Feasible Peer-Mediated Intervention for Autistic Children Using Minimal Speech: A Qualitative Intervention Development Process

PURPOSE

Qualitative engagement with stakeholders in the development of interventions can provide insight into strategies to maximize feasibility in real-life settings. We engaged stakeholders (autistic adults, early childhood educators, early childhood sector leaders and policy influencers, parents of autistic children, and speech-language pathologists) to inform the development of an educator-led peer-mediated intervention (PMI) for autistic preschoolers who use minimal speech that is feasible to implement in inclusive early childhood education and care (ECEC) settings.

METHOD

A qualitative iterative intervention design process was utilized. Stakeholders (N = 15) attended an online workshop and completed a document review exploring the acceptability and feasibility of the proposed embedded PMI. A two-step analysis procedure using the Theoretical Domains Framework and template analysis was conducted to identify the barriers, enablers, and supports to the implementation of embedded PMI in early childhood settings.

RESULTS

While embedded PMI was unanimously acceptable to stakeholders, several participants expressed concerns regarding feasibility. Barriers to the successful integration and implementation of PMI in inclusive preschool contexts included access to skills, knowledge, and resources. Participants identified strategies to overcome modifiable barriers and to enhance the existing enablers. These strategies are reflected in the following themes: build on the familiar, build capacity in augmentative and alternative communication, adopt a whole center approach, adapt to meet the needs of the ECEC setting, and engage in proactive implementation.

CONCLUSION

To address barriers to the implementation of embedded PMI, action is needed at various levels: macro (national/policy), meso (organization/setting), and micro (individual).

Augmentative and alternative communication with children with severe/profound intellectual and multiple disabilities: speech language pathologists' clinical practices and reasoning

PURPOSE

Augmentative and alternative communication (AAC) is recommended to be included in communication interventions directed at children/youth with severe/profound intellectual and multiple disabilities (S/PIMD). Even so, the evidence base for AAC practices with children with S/PIMD is limited. Also, little is known about how frequently AAC is implemented with this target group, which AAC tools and methods are applied, and the related clinical reasoning of speech-language pathologists (SLPs). This study aimed to explore SLPs' beliefs, clinical reasoning and practices in relation to AAC implementation with children/youth with S/PIMD.

MATERIALS AND METHODS

In this sequential, mixed-methods study, 90 SLPs working with children with disabilities within habilitation services in Sweden participated in an online survey. The survey answers were statistically analysed. Subsequently, focus group data were collected from seven SLPs and analysed using thematic analysis.

RESULTS AND CONCLUSIONS

Despite AAC being highly prioritized, SLPs found it challenging and complex to implement with this target group. A wide variety of AAC methods and tools were considered and implemented. Clinical decision-making was a balancing act between competing considerations and was mainly guided by the SLPs' individual, clinical experiences. The resources, engagement and wishes of the social network surrounding the child were considered crucial for clinical decision-making on AAC. Implications for research and practice are discussed.Implications for rehabilitationSpeech-language pathologists (SLPs) seemingly find a wide variety of Augmentative and Alternative Communication (AAC), ranging from unaided methods to assistive technology of various complexity, to be potentially suitable for children/youth with severe/profound intellectual and multiple disabilities (S/PIMD).The motivation and preferences of the social network surrounding the child with S/PIMD seem to influence SLPs' clinical decision-making on AAC to a high degree. Sometimes this may be considered an even more important factor than the abilities of the child.SLPs' clinical decision-making on AAC for children/youth is guided by their individual, clinical experience to a high degree.An increase in family oriented AAC intervention research targeting individuals with S/PIMD could potentially strengthen the association between research and the current, experience-based clinical practice.

Speech-language pathologists' perceptions of augmentative and alternative communication in Thailand

Augmentative and alternative communication (AAC) systems are not well-known and broadly used in Thailand. To begin introducing AAC systems and interventions to children with complex communication needs in Thailand, understanding speech-language pathologists' (SLPs) perceptions toward various AAC systems is an important first step. This study assessed SLPs' perceptions of three AAC modalities: gestural communication, communication boards, and iPad1-based speech-output technologies. A total of 78 SLPs watched three video vignettes of a child using each mode and rated their impressions of intelligibility, ease of learnability and use, effectiveness, and preference. Then they were asked to rate factors on visual analog scales that provided additional insights into their rationales and their preferences for AAC modalities for nonverbal clients and for themselves if they were nonverbal. The results indicated that most of the SLPs rated iPad-based speech-output technologies as being the more intelligible, effective, and preferred mode of communication. Gestural communication was rated as the easiest mode to learn and use for a child with complex communication needs. Despite infrequent use of iPad-based speech-output technologies in Thailand, SLPs' ratings indicated high social acceptance of this modality for promoting communication abilities of children with complex communication needs. Results also revealed some biases and lack of knowledge about AAC systems in Thailand.

Provision of augmentative and alternative communication interventions to Norwegian preschool children with cerebral palsy: are the right children receiving interventions?

Preschool children with cerebral palsy (CP) with no or unintelligible speech need augmentative and alternative communication (AAC), but not all children needing AAC have access to it. This study describes the use and perceived benefit of AAC and explores factors associated with receiving AAC interventions. Using a cross-sectional design, we combined parent-reported data with data from the Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP). Communication, speech and hand function was classified according to the Communication Function Classification System (CFCS), Viking Speech Scale (VSS), and Manual Ability Classification System (MACS), accordingly. The need for AAC was defined as Levels III-V on the CFCS, without simultaneous classification at VSS Level I, and/or Levels III-IV on VSS. Parents reported on child- and family-directed AAC interventions using the Habilitation Services Questionnaire. Of the 95 children (42 females) with CP (M = 39.4 months, SD = 10.3), 14 had communication aids. Of the 35 children (31.4%) defined as needing AAC, 11 had been provided with communication aids. Parents of children with a communication aid reported satisfaction with and frequent use of the aid. Children at MACS Level III-V (OR = 3.4, p = .02) or with epilepsy (OR = 8.9, p < .01) were most likely to have received an AAC intervention. The low proportion of children receiving communication aids indicates an unmet need for AAC interventions among preschool children with CP.

Identifying Implementation Strategies to Increase Augmentative and Alternative Communication Adoption in Early Childhood Classrooms: A Qualitative Study

PURPOSE

The goal of this study was to identify promising implementation strategies that may increase teachers' and speech-language pathologists' (SLPs) adoption of augmentative and alternative communication (AAC) during routine classroom activities.

METHOD

A grounded theory approach was used to collect and code online, semistructured interviews with six special education teachers and 14 SLPs who taught children aged 3-8 years who used AAC in inclusive and self-contained special education classrooms. Interviews were transcribed and coded verbatim using the constant comparative method. During a member checking process, six participants (n = 30%) confirmed their transcripts and commented on emerging themes.

RESULTS

Participants shared a range of implementation strategies to increase AAC use during typical classroom activities, which were organized into seven themes: distribute modern AAC equipment, provide foundational training, share video examples, develop a systematic plan for adoption, deliver practice-based coaching, alter personnel obligations to provide protected time, and connect with professionals. A preliminary thematic map was created to link implementation barriers, strategies, and potential outcomes.

CONCLUSIONS

AAC interventions effective in clinical research can be difficult to translate into routine practice unless investigators directly explore the needs of and demands on educational professionals. Future research should define implementation strategies clearly, solicit feedback from school-personnel, and match implementation strategies to the needs of local schools to support the uptake of AAC interventions in routine classroom settings.

Exploring Classroom Factors and Augmentative and Alternative Communication Use in Qualitative Interviews

PURPOSE

This qualitative study explores classroom contextual factors influencing augmentative and alternative communication (AAC) use in early childhood classrooms.

METHOD

Semistructured interviews were conducted with six special education teachers, 13 speech-language pathologists (SLPs), and one SLP assistant. Interviews were analyzed inductively in a systematic, multistep coding process using the constant comparative method with member checking.

RESULTS

Seven themes were identified that affected AAC use in the classroom. Each theme was organized into three categories: individual-, classroom-, or school-level factors. Three themes were categorized as individual-level factors: Students' AAC systems are unavailable, professionals face challenges obtaining AAC knowledge and skills, and students' disruptive behaviors reduce access to AAC. One theme was a classroom-level factor: Classroom demands prevent AAC use. Finally, three themes were considered school-level factors: The culture of AAC influences AAC acceptance, team collaboration is essential for successful implementation, and teams need administrative support to deliver AAC interventions effectively. Conclusions: Teachers and SLPs felt that collaborative teams with AAC expertise, a school culture that endorsed AAC, and solid administrative support accelerated AAC adoption by normalizing AAC use in the classroom. Due to classroom demands, they struggled to use strategies such as aided AAC modeling and responsiveness during group instruction. Finally, participants emphasized that while it was necessary to customize AAC systems for each student, this individualization makes it harder for staff to learn each system and integrate them into classroom activities.

The relationship between early literacy skills and speech-sound production in students with intellectual disability and communication difficulties: a cross-sectional study

Earlier research and reports from educational practice seem to suggest that teaching early literacy skills may facilitate speech-sound production in students with intellectual disabilities, but further research is needed to confirm a potential connection. This study investigated (1) the relationship between speech-sound production, phonological awareness, and letter-sound knowledge in students with intellectual disabilities and communication difficulties, and (2) to what degree phonological awareness and letter-sound knowledge explain the variance in speech-sound production over and above IQ and chronological age. A group of 116 students, aged 7-21, enrolled in Swedish compulsory schools for students with intellectual disabilities participated in this study. All had limited reading skills. The test results for phonological awareness, letter-sound knowledge, and speech-sound production had a wide range. The results showed that early literacy skills were moderately and significantly correlated with speech-sound production. After controlling for IQ and age in a regression model, the addition of phonological awareness and letter-sound knowledge explained 29% of the variance in speech-sound production. The results suggest that phonological awareness and letter-sound knowledge is associated with speech-sound production and that these associations are not explained by age or IQ. Further research on this group of students should aim to determine causal relationships, for instance, by investigating early reading intervention and the potential effect on speech-sound production.

Comparing Interventions With Speech-Generating Devices and Other Augmentative and Alternative Communication Modes: A Meta-Analysis

PURPOSE

Optimal augmentative and alternative communication (AAC) systems for children with complex communication needs depend in part on child characteristics, child preferences, and features of the systems themselves. The purpose of this meta-analysis was to describe and synthesize single case design studies comparing young children's acquisition of communication skills with speech-generating devices (SGDs) and other AAC modes.

METHOD

A systematic search of published and gray literature was conducted. Data related to study details, rigor, participant characteristics, design information, and outcomes were coded for each study. A random effects multilevel meta-analysis was performed using log response ratios as effect sizes.

RESULTS

Nineteen single case experimental design studies with 66 participants (M age = 4.9 years) met inclusion criteria. All but one study featured requesting as the primary dependent variable. Visual analysis and meta-analysis indicated no differences between use of SGDs and picture exchange for children learning to request. Children demonstrated preferences for and learned to request more successfully with SGDs than with manual sign. Children who preferred picture exchange also learned to request more easily with picture exchange than with SGDs.

CONCLUSIONS

Young children with disabilities may be able to request equally well with SGDs and picture exchange systems in structured contexts. More research is needed comparing AAC modes with diverse participants, communication functions, linguistic complexity, and learning contexts.

Promotion of Communication Access, Choice, and Agency for Autistic Students

PURPOSE

Families and professionals often consider augmentative and alternative communication (AAC) a "last resort" for persons with communication challenges; however, speaking autistic adults have reported that they would have benefited from access to AAC as children. This tutorial discusses the history of this "last resort" practice and its perpetuation within the medical model of disability. The tutorial focuses on communication access, choice, and agency for autistic students.

METHOD

We provide a brief overview of the AAC community and their preferred terminology, review the history of traditional approaches to research on AAC and autism, and then examine the relationship between disability models and ableism to views of spoken language as a priority of intervention. Studies on this topic are rare, and resisting ableism requires acknowledging and honoring disabled people's experiences and expertise. Therefore, we promote autistic expertise within the framework of evidence-based practice and discuss the experiences of autistic people and spoken language. Finally, we consider the role of the speech-language pathologist (SLP) in assessment and offer autistic-based strategies and recommendations for communication support.

CONCLUSIONS

Speaking autistic students who could benefit from AAC may not have access to AAC due to the prioritization of spoken language and lack of awareness of the benefit of AAC. We recommend that SLPs and school-based professionals support and facilitate access, communicative choice, and agency by implementing multimodal communication strategies to include AAC use for autistic students regardless of their spoken language status. Promoting all types of communication and ensuring opportunities for communication across multiple modalities are paramount to a child's agency and self-determination, as is normalization of AAC.

Proceso de evaluación de pictogramas: Catálogo de señalización accesible andaluz

Todas las personas necesitan apoyarse en elementos del contexto para desenvolverse por los entornos de manera autónoma. Esta necesidad se concreta en apoyos específicos cuando las personas tienen dificultades en comprensión permanentes o circunstanciales. Para que un contexto sea accesible universal y cognitivamente se emplean pictogramas para identificar los entornos. Estos pictogramas constituyen una señalética que debe ser validada por procesos estandarizados como describe la Normativa ISO-9186. El objetivo del estudio fue ampliar la base de pictogramas disponibles para la señalización de edificios y evaluar su diseño accesible. Los datos se recogieron por entrevista online y por formulario autocompletado online, en dos fases, la evaluación de la comprensibilidad y la translucidez, así como la calidad perceptual de los pictogramas. Un total de 1462 personas evaluaron la comprensión de los pictogramas y 270 su calidad perceptiva. Dicha muestra incluye participantes de diferentes colectivos y perfiles cognitivos. Se evaluaron 151 pictogramas y fueron 55 los seleccionados por cumplir criterios de comprensión, translucidez y calidad perceptiva. Este resultado supone una contribución relevante a las bases de pictogramas de uso público y privado existentes y aporta recursos señaléticos validados que pueden beneficiar a todas las personas facilitando la accesibilidad cognitiva en los espacios.

Technology assisted language intervention (TALI) for children who are deaf/hard of hearing: promising impact on pragmatic skills

Children who are deaf and hard of hearing (DHH) often demonstrate pragmatic language difficulties which can impact academic and social outcomes. This randomized control trial for DHH children, ages 3-12 years, explored the Technology-Assisted Language Intervention (TALI), incorporating augmentative and alternative communication technology (AAC) into traditional speech/language therapy, compared to treatment-as-usual (TAU) to determine impact on pragmatics. Pragmatic outcome measures included parent reported Pragmatics Profile of the CELF-5 (for children age ≥5 years) and CELF-P Descriptive Pragmatics Profile (for children <5 years) in addition to parent reported Social and Communication domains of the Vineland Adaptive Behavior Scales,Third Edition (VABS). Over 24 weeks, children ≥5 years in the TALI made significantly more progress (increase in raw scores) on the Pragmatics Profile compared to children in TAU (12.7 points vs. -6.0 points; p = 0.04) and also showed significant gains on two of the three subscales. For children ≥5 years, no significant VABS changes were seen in either intervention group. For children <5 years, there were no statistically significant differences in growth on the CELF-P total pragmatics raw score or on any subdomain. However, children in TALI had significant increases in the mean VABS Communication (86.7-99.1) and Social domain standard scores (91.8-97.4;p = 0.01), while gains for children in TAU on the Communication and Social domain standard scores were not statistically significant. These promising results support the need for additional research exploring the effectiveness of AAC supported speech/language therapy to enhance DHH children's pragmatic language skills.

It's Never Too Late: Debunking Myths About Communication and Adults With Severe Disabilities

Communication infuses all dimensions and stages of life, influencing one's self-determination and quality of life. A number of empirical studies have demonstrated that people with severe disabilities continue to develop communication and language skills well into their adult years and make measurable gains when provided with appropriate communication services and supports. Several myths about age, ability, and experiences limit opportunities for persons with severe disabilities. In this paper, we confront and address these myths.

A pediatric near-infrared spectroscopy brain-computer interface based on the detection of emotional valence

Brain-computer interfaces (BCIs) are being investigated as an access pathway to communication for individuals with physical disabilities, as the technology obviates the need for voluntary motor control. However, to date, minimal research has investigated the use of BCIs for children. Traditional BCI communication paradigms may be suboptimal given that children with physical disabilities may face delays in cognitive development and acquisition of literacy skills. Instead, in this study we explored emotional state as an alternative access pathway to communication. We developed a pediatric BCI to identify positive and negative emotional states from changes in hemodynamic activity of the prefrontal cortex (PFC). To train and test the BCI, 10 neurotypical children aged 8–14 underwent a series of emotion-induction trials over four experimental sessions (one offline, three online) while their brain activity was measured with functional near-infrared spectroscopy (fNIRS). Visual neurofeedback was used to assist participants in regulating their emotional states and modulating their hemodynamic activity in response to the affective stimuli. Child-specific linear discriminant classifiers were trained on cumulatively available data from previous sessions and adaptively updated throughout each session. Average online valence classification exceeded chance across participants by the last two online sessions (with 7 and 8 of the 10 participants performing better than chance, respectively, in Sessions 3 and 4). There was a small significant positive correlation with online BCI performance and age, suggesting older participants were more successful at regulating their emotional state and/or brain activity. Variability was seen across participants in regards to BCI performance, hemodynamic response, and discriminatory features and channels. Retrospective offline analyses yielded accuracies comparable to those reported in adult affective BCI studies using fNIRS. Affective fNIRS-BCIs appear to be feasible for school-aged children, but to further gauge the practical potential of this type of BCI, replication with more training sessions, larger sample sizes, and end-users with disabilities is necessary.

Supporting Emergent Bilinguals Who Use Augmentative and Alternative Communication and Their Families: Lessons in Telepractice From the COVID-19 Pandemic

PURPOSE

The purpose of this project was to examine the effect of the COVID-19 pandemic on speech-language pathologist (SLP) service provision for emergent bilinguals who use augmentative and alternative communication (AAC). One prominent issue in AAC service delivery is the efficacy and feasibility of providing AAC services via telepractice. The COVID-19 pandemic intensified this issue as most providers, clients, and families adjusted to remote service delivery models. While emerging evidence supports telepractice in AAC, little is known about the potential benefits and challenges of telepractice for emergent bilinguals who use AAC and their families.

METHOD

Data were collected via a nationwide survey. Licensed SLPs (N = 160) completed an online questionnaire with Likert-type, multiple-choice, and open-ended questions, analyzed using mixed methods.

RESULTS

Findings illustrated a shift in service delivery from in-person to telepractice and hybrid (both telepractice and in-person) models. Overall, child intervention outcomes declined for emergent bilinguals who used AAC during the COVID-19 pandemic, regardless of service delivery format. However, collaboration increased for many providers and families. Qualitative analyses highlighted barriers to AAC service provision for emergent bilinguals who use AAC that were exacerbated by the COVID-19 pandemic, as well as factors that facilitated collaboration and family engagement.

CONCLUSION

These findings suggest that, despite challenges, telepractice or hybrid services may be a promising approach to provide more culturally responsive, family-centered care for emergent bilinguals who use AAC.

Black Children With Developmental Disabilities Receive Less Augmentative and Alternative Communication Intervention Than Their White Peers: Preliminary Evidence of Racial Disparities From a Secondary Data Analysis

PURPOSE

Ensuring equitable access to augmentative and alternative communication (AAC) intervention services for children with complex communication needs (CCN) is crucial. Evidence suggests that racial disparities exist in access to communication interventions, disadvantaging Black children. However, no research has investigated specifically the evidence for racial disparities in AAC services for children with developmental disabilities and CCN.

METHOD

The current study applied post hoc data analysis methods within a preexisting, open-access data set to explore preliminary evidence of racial disparities in AAC intervention. Amount of AAC intervention was compared for Black versus white 1 preschool students at study initiation (M age = 3;8 [years;months]) and 2 years later at study completion (M age = 5;10).

RESULTS

Black preschool students were reported to receive significantly less AAC intervention per week as compared to their white peers, both at study initiation and 2 years later. By study end, 75% of the Black children were receiving less than 60 min of AAC intervention per week, an inadequate amount to achieve meaningful gains given their significant disabilities.

CONCLUSIONS

It is unclear what mechanisms may contribute to the observed disparities; however, it is critical that concrete steps are taken by individual speech-language pathologists, school districts, preservice preparation programs, and researchers to identify inequities in AAC services and take actions to rectify them. Future research is essential to investigate the potential factors contributing to inequalities and determine effective interventions to address them.

A Systematic Review of Augmentative and Alternative Communication Interventions for Children Aged From 0 to 6 Years

PURPOSE

This systematic review evaluates the latest available evidence regarding augmentative and alternative communication (AAC) interventions in children from 0 to 6 years old diagnosed with various disabilities.

METHOD

A systematic search was conducted in MEDLINE (OVID), PsycINFO (EBSCO), ERIC (ProQuest), SCIELO (WOS), Teacher Reference Center (EBSCO), and Education Database (ProQuest), and studies on AAC interventions in children from 0 to 6 years old diagnosed with various disabilities were selected independently by two reviewers (A.L.-R. and N.I.M.) according to the purpose of the review.

RESULTS

Twenty-nine of 1,709 studies met the inclusion criteria for this review. The methodological quality of the included studies was assessed, and the characteristics and results of the studies were extracted by a descriptive analysis (O.L.S. and M.O.-V.).

CONCLUSION

This analysis revealed that children with different diagnoses show improvements in expressive and receptive communication, functional communication behaviors, communication participation skills, interaction strategies, and symbol and multisymbol production and comprehension by using various AAC systems.

Speech-language pathologists’ practices in augmentative and alternative communication during early intervention

This survey study examined augmentative and alternative communication (AAC) practices reported by early intervention speech-language pathologists (SLPs) across the United States (N = 376). The study examined (a) types of AAC that SLPs reported using (i.e., sign language, photographs, pictures, symbols, talking switches, and iPad apps or dedicated speech-generating devices); (b) SLPs' perspectives on the influence of child spoken language ability on AAC recommendations; (c) factors that influenced AAC decision-making within early intervention; and (d) perceived barriers associated with AAC implementation. SLPs reported that they were significantly more likely to introduce all types of AAC to children without spoken language abilities compared to children in later stages of language development. On average, they were most likely to report using or recommending sign language and photographs, and least likely to report using or recommending talking switches or speech-generating devices. Of the options provided, child expressive and receptive language abilities were rated as the most important factors to consider when determining AAC use, followed by cognitive ability, diagnosis, and chronological age. SLPs identified caregiver buy-in and carryover across providers as the most significant barriers to AAC implementation. Recommendations for future research and current AAC practices within early intervention are discussed.

Clinical utilisation of the Infant Monitor of vocal Production (IMP) for early identification of communication impairment in young infants at-risk of cerebral palsy: a prospective cohort study

AIM

To report prospective longitudinal data of early vocaliszations of infants identified "at-risk" of cerebral palsy (CP) for early identification of communication impairment.

METHOD

This case-control longitudinal prospective cohort study reports on the assessment of 36 infants, 18 identified as at-risk of CP at the time of enrolment and 18 typically developing (TD) children, at three time points: 6 months, 9 months and 12 months of age, Data were obtained through criterion and norm referenced assessments of vocaliszation behaviors.

RESULTS

Early vocal behaviors of infants identified as at-risk of CP did not differ from their age matched peers at 6 months of age, however, significant group differences emerged at 9 and 12 months when pre-canonical and canonical babble typically emerge. Generalized linear mixed models analysis showed that the rate of development of early language ability and more complex speech-related vocal behaviors was slower for infants at risk of CP when compared to TD infants, with over 75% of infants with CP showing below normal vocal production and impaired language by 12 months of age.

INTERPRETATION

Our data suggest characteristics of infant vocalizations associated with pre-canonical and canonical babbling provide a strong evidence base for predicting communication outcomes in infants at risk of CP.

Augmentative and Alternative Communication Supports for Language and Literacy in Preschool: Considerations for Down Syndrome and Autism Spectrum Disorder

Children with Down syndrome and children with autism spectrum disorder have a range of speech abilities during preschool that impacts access to both language and literacy instruction. It is the responsibility of the speech-language pathologist to advocate for and provide intervention using augmentative and alternative communication (AAC) through individualized assessment. This article provides a review of the literature supporting the use of AAC during preschool for both language and literacy development in children with Down syndrome and children with autism spectrum disorder who have limited speech. A small scale exploratory report is discussed to highlight differences in early literacy skills found in children in each group. Implications for AAC intervention during preschool to support both language and literacy are discussed.

The effects of augmentative and alternative communication interventions on the receptive language skills of children with developmental disabilities: A scoping review

PURPOSE

To map and synthesise research evidence of the effects that aided and unaided AAC interventions have on the receptive language of children with developmental disabilities.

METHOD

This scoping review used a four-pronged search strategy (electronic databases, dissertations and theses, hand search, ancestry searches) to identify germane studies. A total of 16 studies met the inclusion criteria. These studies were described in terms of the number of participants, participant characteristics, research design, AAC interventions, intervention outcomes, intervention effects, and quality appraisal.

RESULT

The review revealed positive associations between aided and unaided AAC, vocabulary acquisition and symbol comprehension.

CONCLUSION

AAC interventions may have merit for the development of receptive language skills in children with developmental disabilities. Specific gaps in relation to unaided AAC, aided augmented input strategies, morphological and syntax development, and discourse comprehension are highlighted.

Augmentative and Alternative Communication for Children with Intellectual and Developmental Disability: A Mega-Review of the Literature

Establishing evidence- and research-based practices relies upon research synthesis of individual studies in reviews and meta analyses. Further summarizing scientific evidence about a specific topic by synthesizing reviews is an area of need to determine practices that have a strong evidence base and to identify areas of methodological weakness and gaps in the literature. A mega-review of literature reviews, systematic reviews, and meta-analyses on interventions using aided augmentative and alternative communication (AAC) interventions for children with intellectual and developmental disabilities from 2000 to mid-2020 was conducted. Participant and interventionist demographics, interventions, settings, outcomes, and recommendations of each review were reported and summarized. A MeaSurement Tool to Assess systematic Reviews Revised (AMSTAR 2; Shea et al., 2017) was used to examine the methodological rigor of 84 included reviews. Over the past 20 years, published reviews have increased slightly in methodological rigor but demonstrate a number of methodological weaknesses that detract from the strength of evidence for AAC interventions with this population. Suggestions for improving the methodological rigor of literature reviews and areas for future research specific to AAC interventions are discussed.

A Technology-Assisted Language Intervention for Children Who Are Deaf or Hard of Hearing: A Randomized Clinical Trial

BACKGROUND AND OBJECTIVES

Children who are deaf or hard of hearing (DHH) often have persistent language delays despite early identification and interventions. The technology-assisted language intervention (TALI), which incorporates augmentative and alternative communication technology into a speech-language therapy model, was designed to support language learning. The study objective was to evaluate the impact of the TALI on spoken language outcomes in DHH children.

METHODS

Children aged 3 to 12 years with mild to profound bilateral hearing loss were enrolled in a single-site randomized controlled trial. Children were randomly assigned to receive the TALI or treatment as usual (TAU) (with no change in current care) and were followed for 24 weeks. Primary outcomes included spoken language measures elicited from language samples. Secondary outcomes included standardized assessments. Intention-to-treat analyses were used.

RESULTS

Analyses focused on 41 children randomly assigned to TALI (n = 21) or TAU (n = 20). Among all participants, mean age was 6.3 years (SD 2.5). Over 24 weeks, children in the TALI group, compared with those in the TAU group, had significantly greater increases in the length of phrases they used to express themselves (β = .91 vs .15, respectively; P< .0001). Similar findings were seen with conversational turn-taking and number of different words spoken.

CONCLUSIONS

Providing visual supports for language concepts that are typically challenging for DHH children to acquire allowed children to process and comprehend spoken language more fully. Such strategies can mitigate persistent language delays with the goal of improving lifelong outcomes and independence across settings.

Personalized Early AAC Intervention to Build Language and Literacy Skills: A Case Study of a 3-Year-Old with Complex Communication Needs

Personalized AAC intervention refers to an approach in which intervention is tailored to the individual's needs and skills, the needs and priorities of the individual's family and other social environments, the evidence base, and the individual's response to intervention. This approach is especially relevant to AAC intervention for young children with complex communication needs given their unique constellations of strengths and challenges, and the qualitative and quantitative changes that they experience over time as they develop, as well as the diversity of their families, schools, and communities. This paper provides detailed documentation of personalized AAC intervention over a six-month period for a 3-year-old girl with developmental delay and complex communication needs. The paper describes (1) personalization of multimodal AAC supports to provide this child with the tools to communicate; (2) personalized intervention to build semantic and morphosyntactic skills; and, (3) personalized instruction in literacy skills (i.e., letter-sound correspondences, sound blending, decoding, sight word recognition, reading simple stories, reading comprehension, and encoding skills). Specific goals, instructional materials, and procedures are described; data on speech, language, and literacy outcomes are presented.

Parent Perspectives on Augmentative and Alternative Communication Integration for Children With Fragile X Syndrome: It Starts in the Home

Many children with fragile X syndrome (FXS) have complex communication needs and may benefit from augmentative and alternative communication (AAC). This qualitative study explored how four mother-child dyads used AAC in the home. Data were collected using participant observations, open-ended interviews, and record reviews, and analyzed using grounded theory methods. Findings revealed that mothers found AAC to be a useful tool for addressing their children's complex communication needs, but practical and personal factors impacted its use in the home. This study sheds light on how mothers of children with FXS view and utilize AAC as a way to promote communication at home. Understanding parental perspectives can help to guide professionals in planning appropriate AAC interventions specific to FXS.

Using AAC to unlock communicative potential in late-talking toddlers

PURPOSE

The purpose of this study was to report on modifications we made to a standardized input-based word learning treatment for two late-talking toddlers. The modifications were the addition of an augmentative alternative communication (AAC) device and the requirement that the children use this device, or speech, to communicate.

METHOD

We used a single-subject design to track late-talking toddlers' progress through an input-based word learning treatment, which was part of a larger study. Because the input-based treatment protocol was not effective for each toddler based on absent or clinically insignificant treatment effect sizes, we modified the protocol. The modifications were meant to address each child's potential over-reliance on nonverbal communication and the potential impact of speech sound delay. We then measured their linguistic output.

RESULTS

Both toddlers showed no evidence of learning during the input-based treatment. Each child's linguistic output increased by over 600 % once we made the protocol modification and introduced the AAC device. They used both AAC and vocal speech to communicate. Both toddlers produced novel words, and one began to produce multiple word combinations.

DISCUSSION

While input-based therapy has an evidence base and has been successful for some toddlers, it may require modifications for children who have not learned the pragmatic convention of using spoken language, and for children with difficulty with speech sound production.

Maternal Input and Child Language Comprehension During Book Reading in Children With Down Syndrome

Purpose Communication interactions between parents and children during shared book reading impact a child's development of both language and literacy skills. This study examined maternal language input and child expressive communication during a shared book reading activity in children with Down syndrome (DS) and children with typical development (TD). Additionally, children's receptive language was examined to understand the relationship between maternal language input and child receptive language ability. Method Participants included 22 children with DS and 22 children with TD between 22 and 63 months of age and their mothers. Each mother-child dyad participated in a 7-min naturalistic shared book reading activity. Results Compared to mothers of children with TD, mothers of children with DS used significantly more utterances with less grammatical complexity, but a similar range of vocabulary diversity. Mothers of children with DS used more questions, descriptions, gestures, and labels, whereas mothers of children with TD used nearly half of their utterances to read directly from books. Children with DS communicated at a similar frequency compared to their peers with TD; however, they produced significantly fewer spoken words. Conclusions This study reveals important differences between early shared book reading interactions and provides implications for future research targeting parent-coached intervention strategies that may enhance children's learning during shared book reading by providing access to expressive language and print instruction.

Communication ability and communication methods in children with cerebral palsy

AIM

To investigate if communication ability and method were related to each other and to age, sex, gross motor function, or manual ability in children with cerebral palsy.

METHOD

This cross-sectional study used data registered in the Swedish Cerebral Palsy Surveillance Program registry, involving 3000 children aged 0 to 18 years. Pearson's χ² test and Spearman's correlation were used to test associations between variables.

RESULTS

Communication ability and method were related to each other and to age, gross motor function, and manual ability. Aided communication methods were more frequently used among older children. The more functional the communication was, the less use of unaided communication occurred. Different communication methods were used across all Communication Function Classification System (CFCS) levels. Speech was most common in more functional levels, used by 72% of the children. Forty-five per cent were considered effective communicators in all environments. For classification of communication level and method, some recurring registration errors were made by the raters.

INTERPRETATION

Some raters may need clarification on interpretations of CFCS instructions. Results indicate that children should be presented to aided augmentative and alternative communication and manual signs earlier and to a greater extent.

Development of consensus-based guidelines for managing communication of individuals with Rett syndrome

Difficulties with communication have a profound impact on the lives of individuals with Rett syndrome and their caregivers. Globally, many families report difficulty accessing appropriate and timely information and services from professionals with expertise in augmentative and alternative communication (AAC) as it pertains to Rett syndrome. To address this need, international consensus-based guidelines for managing the communication of individuals with Rett syndrome were developed by combining available evidence and lived experience with expert opinion. A two-phase Delphi survey was built on statements and recommendations extracted from a review of over 300 pieces of literature combined with survey responses from communication professionals and caregivers. All statements that reached a pre-determined threshold of ≥70% agreement were incorporated into guidelines that consist of 268 statements and recommendations relating to (a) rights of the individual; (b) beliefs and attitudes of communication partners; (c) professional knowledge and team work; (d) strategies to optimize engagement; (e) assessment; and (f) intervention (targets and goals, techniques), including the use of AAC. To date, this project is the largest of its kind, with 650 participants from 43 countries contributing to development of consensus-based guidelines for Rett syndrome.

Growing up with AAC in the digital age: a longitudinal profile of communication across contexts from toddler to teen

Smart technology (e.g., smartphones, smartwatches, tablets) and the age of information have transformed our society and changed the lives of individuals who rely on assistive technology. This study provides a detailed description of an adolescent growing up in the digital age using augmentative and alternative communication (AAC). It documents the participant's development across language, cognitive, and social domains from ages 2- to 15-years-old, and explores how changes in AAC technology and contextual factors contributed to broad-based outcomes associated with AAC use. In general, results from standardized assessments show growth or stability across domains from ages 2-15. Data from a parent interview provides a narrative description of AAC device use, AAC interventions, and school and family environments. Despite communicative challenges, the participant leveraged advances in AAC technology to develop communicative competence and creatively used his smart devices and the Internet to interact with friends both online and in person.

Teaching Preschoolers With Down Syndrome Using Augmentative and Alternative Communication Modeling During Small Group Dialogic Reading

Purpose This study evaluated the effect of aided augmentative and alternative communication modeling (AAC-MOD) on the communication skills of children with Down syndrome (DS) during small group dialogic reading. Method Four children with DS between 3;1 and 5;3 (years;months; M = 4;5) and 5 typically developing peers between 3;5 and 5;9 (M = 4;3) participated. Effects were examined using a multiple probe across behaviors design with 4 children with DS. To simulate typical dialogic reading routines in inclusive classrooms, a strategy called Read, Ask, Answer, Prompt (Binger, Kent-Walsh, Ewing, & Taylor, 2010) was applied during the baseline and intervention sessions. Results A functional relation was demonstrated between (a) AAC-MOD and percentage of correctly identified symbols for 3 participants, (b) AAC-MOD and rate of symbolic communication for 2 participants, and (c) AAC-MOD and number of different words for 2 participants. Increases in number of multiple word combinations occurred for 2 participants. All 4 children maintained their percentage of correctly identified symbols. Increases in rate of symbolic communication did not generalize to thematic play contexts, a distal measure of response generalization. Conclusion AAC-MOD is an effective strategy for teaching target vocabulary and increasing rate of symbolic communication in young children with DS.

Predictors of Expressive Language Change for Children with Autism Spectrum Disorder Receiving AAC-Infused Comprehensive Intervention

Comprehensive interventions for children with autism spectrum disorder (ASD) often incorporate augmentative and alternative communication (AAC); however, variability in outcomes exists even among children who access similar intervention. This study investigated predictors of expressive language change for 48 children with ASD aged 31 to 67 months receiving AAC-infused intervention. The relationships between participants' initial responses to AAC and expressive language change were examined. Commonly reported predictors (IQ, chronological age, ASD symptomatology) did not significantly predict expressive language change. AAC factors (visual attention, object play, word learning) entered at Step 2 of a hierarchical multiple regression, explained an additional 42% of the variance. The findings provide preliminary data on child characteristics associated with expressive language changes within AAC-infused comprehensive interventions.

Speech-Language Pathologists' Knowledge and Consideration of Factors That May Predict, Moderate, and Mediate AAC Outcomes

The aims of this study were to examine speech-language pathologists' (SLPs) knowledge and consideration of factors found in research when making clinical decisions regarding AAC for children with Autism Spectrum Disorder (ASD), and to reveal additional factors identified based on SLPs' clinical practice. A 20-question mixed-methods survey was completed internationally by 187 certified SLPs. Overall, SLPs showed some familiarity with the research and considered factors found in research when making clinical decisions. SLPs also identified 20 factors that were not identified in the most recent systematic review that may predict, moderate, and/or mediate outcomes. This information may contribute to advancing clinical services regarding AAC as well as guide future research investigating the mechanisms by which children with ASD respond to AAC interventions.

Enhancing language in children who are deaf/hard-of-hearing using augmentative and alternative communication technology strategies

BACKGROUND

Despite early identification and intervention, many children who are deaf/hard of hearing (D/HH) demonstrate significant gaps in language development which can directly impact social interactions.

AIMS

The objective of this pilot study was to determine whether integrating augmentative and alternative communication (AAC) core word language strategies into a speech-language therapy program for young children who are D/HH improves spoken language outcomes.

METHODS

Eleven young children, median age 5 years 7 months (range 3y;11 m to 10y;8 m) with bilateral hearing loss were enrolled in a single-case experimental design and completed a 24-week intervention that incorporated high-tech AAC strategies into a traditional speech-language therapy model (technology-assisted language intervention or TALI). The goal of the TALI was to improve spoken language development in children who were D/HH. Language samples were collected throughout the study and pragmatic language was assessed pre and post intervention.

RESULTS

At the end of 24 weeks, children demonstrated a significant increase in their mean length of utterance, number of words spoken, and mean turn length according to language samples. Children also made gains in their pragmatic skills pre to post intervention.

CONCLUSIONS

Results of this study suggest that using AAC core word language strategies delivered via iPad technology may support continued and rapid spoken language skill growth among young school-age children who are D/HH. By leveraging AAC technology, we are pioneering a structured and dynamic approach to language learning, building an effective foundation for concepts and grammar for children who are D/HH.

Providing Supportive Hospital Environments to Promote the Language Development of Infants and Children Born Prematurely: Insights From Neuroscience

INTRODUCTION

Rapid neural development occurs beginning in utero and extending throughout a child's first years of life, shaped by environmental input, which is essential for language learning. If this development is disrupted by premature birth and/or related repeated hospitalizations, atypical language development may result even in the absence of severe neurologic damage.

METHOD

This narrative review describes typical neurodevelopment associated with language and the atypical neurodevelopment often experienced by children born prematurely that can adversely affect their language development.

RESULTS

We describe evidence-based intervention strategies applicable in the hospital setting that can support the language development of young children who are born prematurely.

DISCUSSION

To promote neurodevelopmental growth that will support language learning, children born prematurely need to engage in supportive interactions with others. Awareness of evidence-based strategies can equip health care staff to provide a supportive hospital environment to promote the language development of children born premature.

Practitioner Implementation of Communication Intervention With Students With Complex Communication Needs

This study evaluated the effects of a pyramidal training approach that used an expert trainer who taught teachers how to train their paraeducators. Three special education teachers were taught to train four paraeducators to provide students with intellectual and developmental disabilities opportunities to initiate (OTI). A multiple baseline design across participants was used to evaluate the rate and fidelity that paraeducators provided OTI and least to most prompting strategies with students. Rates increased from 0 to an average of .58 per minute. Fidelity of implementation increased from 0% to an average of 94.5%. Maintenance data were recorded for three paraeducators. Schools should consider using this cost- and time-effective training model with staff.

Complex intervention in augmentative and alternative communication (AAC) care in Germany: a study protocol of an evaluation study with a controlled mixed-methods design

INTRODUCTION

The current practice of service delivery in Germany for people with complex communication needs (CCN) who are in need of augmentative and alternative communication (AAC) is characterised by diverse problems, including a lack of clarity in the responsibilities of the service providers involved. To address these issues a new service delivery model has been put in place, implemented in three AAC counselling centres for patients with a particular health insurance across Germany. The implementation of a new service delivery model aims to improve individualised service delivery. The model goes beyond standard care by adding case management, counselling, AAC training and, if needed, AAC therapy. This study aims to evaluate the effectiveness of this complex intervention.

METHODS AND ANALYSIS

In consideration of the complexity of the new service delivery model, formative and summative evaluation will be conducted. The formative evaluation will provide data based on qualitative and quantitative assessments of the competences and perspectives of all involved stakeholders, including a proxy measurement of persons with CCN. The summative evaluation will include a controlled study design as the new service delivery model will be compared against the service delivery in an existing contract and against data gathered from caregivers of AAC users provided with standard care. With the exception of the individual interviews the data will be collected from proxies-that is, informal and formal caregivers.

ETHICS AND DISSEMINATION

Data collection, storage and evaluation meet the currently valid data protection regulations. Consultation by the responsible data protection officer of the Oldenburg Medical School and a positive vote from its Ethics Committee were obtained prior to the start of the study. Dissemination strategies include the presentation of the obtained data and results in the form of publications and at conferences.

Framework for Selecting Vocabulary for Preliterate Children Who Use Augmentative and Alternative Communication

Purpose Nearly 50% of school-based speech-language pathologists (SLPs) provide services to school-age children who use augmentative and alternative communication (AAC). However, many SLPs report having insufficient knowledge in the area of AAC implementation. The objective of this tutorial is to provide clinicians with a framework for supporting 1 area of AAC implementation: vocabulary selection for preliterate children who use AAC. Method This tutorial focuses on 4 variables that clinicians should consider when selecting vocabulary: (a) contexts/environments where the vocabulary can be used, (b) time span during which the vocabulary will be relevant, (c) whether the vocabulary can elicit and maintain interactions with other people, and (d) whether the vocabulary will facilitate developmentally appropriate grammatical structures. This tutorial focuses on the role that these variables play in language development in verbal children with typical development, verbal children with language impairment, and nonverbal children who use AAC. Results Use of the 4 variables highlighted above may help practicing SLPs select vocabulary that will best facilitate language acquisition in preliterate children who use AAC.

An online community of practice to improve intervention for individuals with complex communication needs

Collaboration and information sharing are essential in the fast moving world of augmentative and alternative communication (AAC). This paper describes communities of practice, justifies their need in AAC, and introduces the Communication Matrix Community of Practice (CMCoP)-an online community of practice for professionals and family members supporting individuals at the earliest stages of communication development. Stakeholders share the goal of advancing language and communication intervention for individuals with complex communication needs. Features of the CMCoP include a community forum for discussing and sharing information; collections of posts by professionals and nonprofessionals on various topics; an events calendar of AAC-related activities relevant to stakeholders; and a shared science section offering portraits of the communication skills of various populations with severe communication disorders. The utility of these and other CMCoP features in supporting the implementation of AAC assessment and intervention strategies is discussed.

Toward greater involvement of youth with complex communication needs in the selection of augmentative and alternative communication devices

Purpose: The study aim was to examine the measurement properties of the Youth Evaluation of Products Scale for Augmentative and Alternative Communication (YEP-AAC) as a means to understand the product attitudes of youth toward their AAC devices.Methods: In study 1, four males and two females between the ages of 8 and 17 years (median age = 14 years) participated in face-to-face interviews. A researcher administered the YEP-AAC and then asked youths to explain the rationale for their item ratings. Two researchers analyzed masked transcripts of the interviews to predict the valence of item ratings assigned by youths. In study 2, 18 families participated in a mailed survey to examine the reliability and validity of the scale domains. Seventeen mothers/one father and their children (9 male/9 female) between the ages of 10 and 20 years participated (median age = 16 years).Results: The level of chance-corrected agreement between valences converted from youth ratings on the YEP-AAC and those assigned by researchers was fair (weighted kappa = 0.38). Internal consistencies of the scale domains were acceptable. Youths who rated their AAC devices more favourably had higher functional communication as hypothesized.Conclusion: The two studies provide support for the face validity, internal consistency and convergent validity of the YEP-AAC as a measure of the product attitudes of youth with complex communication needs.Implications for rehabilitationDeveloping reliable ways to understand the product needs, preferences and values of youth with complex communication needs will help to support the selection, acquisition and use of augmentative and alternative communication (AAC) devices.Consumer socialization helps to explain how youth may acquire the skills, knowledge and experience relevant to their role as AAC consumers.Reliable youth-report questionnaires that are grounded in consumer socialization provide an expedient way to understand the product attitudes of young consumers with complex communication needs.
