Typically, speech-generating device interventions for children with autism spectrum disorder have often involved discrete-trial approaches. Recently, there has been a trend towards using naturalistic developmental behavioral approaches for children with autism spectrum disorder. These approaches embed behavioral principles within natural contexts, routines, and social interactions. Natural communication partners (e.g., parents, peers) are also often involved in such approaches. There is a need for speech-generating device research that explores the utility of these more naturalistic approaches across a variety of device display formats. This symposium will explore how different speech-generating device display formats (including simple grid-based formats, dynamic navigational grids, and visual scene displays) can be incorporated into different natural routines (e.g., play, art activity, meal time, conversation) with natural communication partners (parents and peers). All three studies embedded a variety of behavioral techniques (e.g., prompting, time delay) into natural routines in order to encourage the use of speech-generating devices for communicative purposes. Results indicate that naturalistic interventions with behavioral components can be effective for teaching communication responses to individuals with ASD across a range of display formats.

The target audience for this event would be BCBAs and related practitioners with interests in behavioral approaches to speech-generating device interventions (e.g., special education teachers, speech-language pathologists).

This study evaluated the effectiveness of embedded naturalistic instruction for teaching multi-step speech-generating device (SGD) responses to three preschool-aged males with autism spectrum disorder (ASD). Parents were taught to embed opportunities to request objects, request help, reject items, and make comments during every-day routines (e.g., play, meal time). During intervention, parents used time delay, prompting, reinforcement, and device proximity to encourage the use of two-step SGD responses on a grid-based display with category folders (e.g., vehicles, animals). The display format was selected based upon prior dynamic assessment to determine appropriate formats. Effects of intervention were evaluated using a multiple-probes across participants design. For object requesting, all three participants showed an immediate increase in responding that maintained at high levels. Other pragmatic functions also increased, but at a more gradual pace. All three participants showed generalized responding when new items were introduced, and when display pages with a larger array of folders and vocabulary items were assessed.

Social interactions are a critical component of quality of life. These interactions are often complicated for adolescents with autism spectrum disorder (ASD), as they experience difficulty in participating in social interactions with their peers. The challenges of social interactions are further intensified for those adolescents with ASD who have difficulty with speech. Speech-generating device (SGD) interventions designed to support communication during social interactions with peers in natural environments are needed for these individuals. Video visual scene displays (video VSDs) capture dynamic routines that support communication. This study used a multiple-probe across participants design to assess the impact of an intervention using videos with integrated visual scene displays (video VSDs), presented on a tablet-based app, on the communication of four adolescents with ASD and complex communication needs and their peer partners. The automatic pausing of a video at key points served as a prompt for communication opportunities and provided the necessary vocabulary within the VSD. Following intervention, all four participants demonstrated an increase in communicative turns and in modes of communication used (including speech), suggesting that video VSDs may be an effective tool for supporting social communication.
