Purpose The purpose of this study was to determine the effects of augmentative and alternative communication (AAC) intervention using a speech-generating device (SGD) on acquisition, maintenance, and generalization of multistep requesting and generic small talk in three children with severe autism spectrum disorder (ASD) between the ages of 7 and 13 years. Method A multiple-baseline design across participants combined with a posttreatment multiple-generalization-probe design was used to assess acquisition, generalization, and maintenance of target communicative behaviors with the experimenter and the participants' familiar communication partners (FCPs). Intervention was composed of systematic instruction in the use of an SGD using least-to-most prompting, constant time delay, error correction, and reinforcement. Results Visual analysis established a strong functional relationship between the independent variable and the two dependent variables (i.e., requesting preferred activities, engaging in generic small talk) for all three participants. Effect size indicator analyses corroborated these findings, indicating strong effects for performing multistep requesting and medium effects for engaging in generic small talk. All participants were able to generalize the acquired communicative behaviors to request new and untrained snacks and activities and engage in generic small talk with FCPs who were not part of the training. Maintenance of acquired communicative behaviors was demonstrated 3 weeks post completion of intervention. Conclusion This study provides preliminary evidence that AAC intervention using an SGD and incorporating least-to-most prompting, constant time delay, error correction, and reinforcement is effective in terms of multistep requesting and generic small talk behaviors in children with severe ASD.

Individuals with Autism Spectrum Disorder (ASD) who have limited natural speech may communicate using unaided and/or aided augmentative and alternative communication (AAC) and may combine potentially communicative behaviors in multimodal ways. Unaided AAC refers to the use of an alternative and augmentative system of communication that does not require aids external to the communicator's body. Aided AAC relies on the use of aids external to the body, such as pictures or a speech-generating device (SGD). Potential communicative acts refer to any behavior that others interpret as meaningful, including informal (unconventional) behaviors, such as body or hand movement, as well as a few words or (conventional) symbols, such as pointing to pictures. Foundational skills, such as communicative gesture and joint attention, can inform multimodal AAC practices in young children with or at risk for ASD. A data tracker of motor hand, oral-motor/vocal/verbal behaviors, and AAC is provided based on past research in children with or at risk for ASD. The data tracker highlights behaviors ranging from informal to conventional communication forms that may be produced in multimodal ways.

Purpose The aim of this research study was to examine common practices of speech-language pathologists (SLPs) who work with children with autism spectrum disorder (ASD) with respect to whether or not SLPs consider processing differences in ASD or the effects of input during their instruction. Method Following a qualitative research method, how SLPs instruct and present augmentative and alternative communication systems to individuals with ASD, their rationale for method selection, and their perception of the efficacy of selected interventions were probed. Semistructured interviews were conducted as part of an in-depth case report with content analysis. Results Based on completed interviews, 4 primary themes were identified: (a) instructional method , (b) input provided , (c) decision-making process , and (d) perceived efficacy of treatment . Additionally, one secondary theme, training and education received , was identified . Conclusions Clinicians reported making decisions based on the needs of the child; however, they also reported making decisions based on the diagnostic category that characterized the child (i.e., ASD). The use of modeling when teaching augmentative and alternative communication to individuals with ASD emerged as a theme, but variations in the method of modeling were noted. SLPs did not report regularly considering processing differences in ASD, nor did they consider the effects of input during instruction.

Purpose Technology features that maximize communicative benefit while minimizing learning demands must be identified and prioritized to amplify the efficiency and effectiveness of augmentative and alternative communication (AAC) intervention. Picture symbols with paired text are a common representation feature in AAC systems for children with autism spectrum disorder (ASD) who are preliterate, yet little research about their comparative benefit exists. Method Four school-age children with ASD and limited speech who were preliterate participated in two single-subject studies. In one study, communication of high imageability words (e.g., nouns) on an AAC app during a book-reading activity was compared across two representation conditions: picture symbols with paired text and text only. In the second study, communication of low imageability words (e.g., verbs) was compared. Both studies had baseline, intervention, generalization, and maintenance phases. Results Prior to intervention, participants communicated across both representation conditions at low rates except two participants who were relatively successful using picture symbol with paired text representations of high imageability words. In response to intervention, all participants demonstrated increases in communication across representation conditions and maintained the increases. Participants demonstrated generalization in the text-only representation condition. Conclusions Children with ASD who were preliterate acquired communication at comparable rates regardless of whether an AAC app utilized picture symbol with paired text or text-only representation. Therefore, while larger scale research is needed, clinicians and technology developers could consider increasing the use of text in AAC representation given the inherent value associated with learning to recognize written words.

Introduction Social validation or the inclusion of stakeholders in the research process is beneficial, as it may decrease bias, increases efficacy, and prevents harm. For direct stakeholders such as individuals with autism spectrum disorder (ASD), social validation has mostly included participants who do not experience significant speech, language, and communication limitations while frequently omitting individuals with ASD who have complex communication needs (CCN). The presence of CCN indicates that augmentative and alternative communication (AAC) strategies are needed for individuals to express themselves. Social validation should not be limited to being participants in an intervention but should include involvement in the research process. This requires an understanding of the current trends, levels, and mechanisms of involvement in AAC research. Purpose This review aimed to identify and describe the inclusion of direct stakeholders with ASD in the social validation of AAC research. Method A scoping review was conducted following the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews) methodology to identify AAC research that included stakeholders with ASD (direct and indirect) for social validation and to evaluate their level of involvement using the Typology of Youth Participation and Empowerment pyramid framework. Results Twenty-four studies were identified. Studies primarily included indirect stakeholders (e.g., caregivers) giving in-depth perspectives, while direct stakeholders were limited to being intervention participants. Conclusions Voices of direct stakeholders with ASD and CCN remain limited or excluded in research. Reasons for the exclusion of individuals with ASD and CCN from research and strategies for future inclusion are raised and discussed.

Many factors are important when planning and implementing strategies for teaching in the multiple disability/cross-categorical classroom. No two students' needs are alike; however, two areas are invariably a topic of discussion and lead many of the decisions being made in the individual's educational program: communication and presumed competence. The following chapter includes student narratives for a child with multiple disabilities as well as a child with autism spectrum disorder. Each child exhibits a significant communication delay and is considered to be non-verbal. The narratives along with strategies used to support the students have been included. Common misconceptions about augmentative and alternative communication use and presumed competence among students with significant communication needs are examined as well as research and theory concerning these areas.
