Abstract:

Augmentative and alternative communication (AAC) software plays a critical role in supporting functional communication for individuals with autism spectrum disorder (ASD), specifically for those with complex communication needs. Despite the wide availability of AAC software devices, limited research has investigated software-specific barriers for individuals with ASD. Current research suggests that TD Snap can support communication outcomes when adequately tailored and supported, though evidence specific to individuals with ASD remains limited. Therefore, this study examines the most common barriers associated with AAC software use in the ASD population and to evaluate whether one AAC software system is perceived as more effective than others in improving communication outcomes. Participants involved in this study will be a minimum of 20 licensed speech-language pathologists (SLPs) recruited through professional networks and fliers distributed via email, with access to the Qualtrics survey provided either through a QR code or a direct link. The survey will use a within-groups design with Likert-scale items for quantitative data and open-ended questions to capture participants’ experiences and perspectives. The survey will examine the following constructs: (1) demographic information, (2) rate of use, (3) software organization, (4) perceived ease of use, (5) perceived generalizability, (6) software skill set, (7) perceived accuracy of responses, and (8) overall opinions gathered through open-ended responses. Based on current literature, it is hypothesized that SLPs will rate TD Snap as more accessible and adaptable for people with ASD to use than other AAC software systems.
