In research, augmentative and alternative communication (AAC) interventions have primarily focused on teaching children to make requests; however, AAC intervention should not stop there. There is a dearth of AAC intervention research targeting other communicative functions, despite there being a significant need to enhance children's communication competence in a variety of social and educational contexts. The purpose of this study was to examine the initial efficacy and feasibility of an AAC narrative intervention on the picture-supported retelling skills of three children with autism, aged 6-9 years old. This multiple baseline across participants design study was preregistered at Open Science Framework (https://doi.org/10.17605/OSF.IO/29SFP). We measured the effect of the intervention on children's inclusion and complexity of story grammar elements and the variety of symbols used to retell untrained stories during a baseline condition, just before each intervention session, immediately following each intervention session, and three weeks after the last intervention session. Parents completed a feasibility questionnaire and documented their children's generalized use of AAC. The AAC narrative intervention improved children's AAC retells, with ascending trends in the intervention condition and scores elevated above baseline after 3 weeks. Parents reported that they perceived the intervention to be appropriate, effective, enjoyable, and planned to use it themselves after the study. Generalized use of AAC outside of intervention sessions was documented for all three participants.

Narratives skills are associated with long-term academic and social benefits. While students with disabilities often struggle to produce complete and complex narratives, it remains unclear which aspects of narrative language are most indicative of disability. In this study, we examined the association between a variety of narrative contents and form indices and disability. Methodology involved drawing 50 K-3 students with Individual Education Programs (IEP) and reported language concerns from a large diverse sample (n = 1074). Fifty typically developing (TD) students were matched to the former group using propensity score matching based on their age, gender, grade, mother’s education, and ethnicity. Narrative retells and generated language samples were collected and scored for Narrative Discourse and Sentence Complexity using a narrative scoring rubric. In addition, the number of different words (NDW), subordination index (SI), and percentage of grammatical errors (%GE) were calculated using computer software. Results of the Mixed effect model revealed that only Narrative Discourse had a significant effect on disability, with no significant effect revealed for Sentence Complexity, %GE, SI, and NDW. Additionally, Narrative Discourse emerged as the sole significant predictor of disability. At each grade, there were performance gaps between groups in the Narrative Discourse, Language Complexity, and SI. Findings suggest that difficulty in Narrative Discourse is the most consistent predictor of disability.
