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.
