Purpose: The purpose of this study was to further evaluate an eight-step partner instructional model developed by Kent-Walsh and McNaughton that has been demonstrated to improve implementation quality and fidelity among adults in clinical and educational settings who support the use of augmentative and alternative communication (AAC) for…

This practice report presents the study of a young girl named Laura, with ASD and visual impairment who was taught basic requesting skills through an adapted augmentative and alternative communication (AAC) system, which is an evidence-based practice for addressing communication with children who have ASD but has limited research efficacy for…

Adolescents with autism spectrum disorder (ASD) often require support both for learning new skills and for communication. This study used a multiple baseline across activities design to evaluate the effect of videos with integrated visual scene displays (video VSDs), presented using a tablet-based app, on the percentage of steps completed…

We evaluated the effectiveness of a behavioral skills training package to teach implementation of Phases 1, 2, and 3A of the picture exchange communication system (PECS) to teachers employed at a therapeutic center for children with autism. Probes in the natural environment and follow-up were conducted with children who were assigned to work with…

Students with visual impairment (VI) were taught to request using the Picture Exchange Communication System (PECS) and tangible symbols. Participants were four males with additional disabilities, 5 to 11 years old, who had little to no functional vision. A functional relation between PECS Phase 1 and requesting was established using a multiple…

This study evaluated the effects of a peer-delivered least prompts intervention and adapted read-alouds of a grade-level novel on correct listening comprehension responses for participants with moderate intellectual disability. Before the study began, participants were taught concepts for wh- words (i.e., who, what, why, when, and where), to…

Communication skills are of great importance for children with developmental disabilities to be functional and independent in their own lives. This paper provides results of a comprehensive literature review on current researched-based intervention strategies that appear effective to increase communication skills for students who have severe…

Two single subject multiple probes across subjects research studies were conducted to evaluate the effectiveness of two instructional writing programs. The objective of the first study was to determine the effect of an instructional program on the selection of initial letters of words by 3 children with developmental disabilities (ages 7-10) who…

This study evaluated the use of facilitated communication (FC) paired with a direct instructional strategy to improve the basic academic skills of 12 youths and young adults with autism. Results did not support use of FC as an educational tool, with subjects averaging below-chance performance in FC and both control conditions. (DB)

An augmentative and alternative communication (AAC) intervention to increase vocabulary acquisition by 5 children (ages 7-9) with mild to moderate mental disabilities was evaluated. The AAC communication procedure resulted in higher rates of vocabulary and sentence selection for each of the children; improvement persisted above baseline levels…
