Students with complex communication needs have increasingly been using non-dedicated communication systems, such as mobile devices, to support their communication needs. This in turn, has led to an increased used of augmentative and alternative communication apps. The main challenge currently faced is the lack of empirically validated apps and…

Purpose: Previous research has shown that many speech-language pathologists (SLPs) lack confidence in conducting augmentative and alternative communication (AAC) evaluations. The AAC Clinical Assessment Project team developed a protocol to help guide SLPs to complete AAC assessments for children with autism spectrum disorder (ASD). This article…

Augmentative and alternative communication (AAC) is a core component of speech pathology practice. However, international literature has highlighted that speech language pathologists (SLPs) may not feel confident or competent in this area. Confidence and competence are critical factors in therapy as they can impact the quality-of-service…

The purpose of this paper was to review best-practice methods of collecting and analyzing speech production data from minimally verbal autistic speakers. Data on speech production data in minimally verbal individuals are valuable for a variety of purposes, including phenotyping, clinical assessment, and treatment monitoring. Both perceptual…

This phenomenological qualitative study explored how eight speech-language pathology specialists in augmentative and alternative communication (AAC) (who self-identified as adult-focused) would approach the AAC assessment process when presented with a case study of an adult with amyotrophic lateral sclerosis (ALS). The general research questions…

Successful intervention outcomes and comprehensive assessment is important for people who rely on augmentative and alternative communication (AAC). However, the literature surrounding AAC assessment remains sparse. The purposes of this project were to describe the AAC assessment process followed by speech-language pathologists (SLPs) and to…

Purpose: As is the case with children who rely on spoken language, speech-language pathologists must support and track the expressive language development of children with complex communication needs who use graphic symbols to communicate. This research note presents a framework of the progression of expressive English sentence development using…

Purpose: The purpose of this study was to explore how speech-language pathologists (SLPs) who are augmentative and alternative communication (AAC) specialists approach the assessment process for 2 case studies, 1 child with cerebral palsy and 1 with autism spectrum disorder. The aim of the study was to answer the following questions: (a) How do…

Background: Communication difficulties are common in cerebral palsy (CP) and are frequently associated with motor, intellectual and sensory impairments. Speech and language therapy research comprises single-case experimental design and small group studies, limiting evidence-based intervention and possibly exacerbating variation in practice. Aims:…

This study explores front-line staff knowledge and perceptions of how people with intellectual disability residing in residential services are supported to communicate effectively. Participants ("n" = 138) completed a self-report questionnaire adapted from an instrument developed by DeSimone & Cascella (2005) "Journal of…

Purpose: The current investigation compared directed scanning and group-item scanning among typically developing 4-year-old children. Of specific interest were their accuracy, selection speed, and efficiency of cursor movement in selecting colored line drawn symbols representing object vocabulary. Method: Twelve 4-year-olds made selections in both…

Many children born with severe and multiple disabilities have complex communication needs and may use no speech or only minimal speech to communicate. Meaningful assessment of their expressive skills to identify communication strengths along a developmental trajectory is an essential first step toward appropriate intervention. This article…

Purpose: This study investigated the effects of a communication partner instruction strategy for parents of children using augmentative and alternative communication (AAC) on the communicative turn taking of their children. Instruction was provided within storybook-reading contexts. Method: Two single-subject multiple-probe-across-participants…

Purpose: This research examined how the presence of color in relation to a target within an augmentative and alternative communication array influenced the speed with which typically developing preschoolers located a target line drawing. Method: Fifteen children over the age of 4 years (from 4;2 [years;months] to 5;4) and 15 children under the age…

Background: Services employing staff to support people with disability usually provide training in a range of areas including communication and managing challenging behaviour. Given that such training can be costly and time-consuming, it is important to evaluate the evidence presented in support of such programs. Efficacy in clinical practice is…
