Video-based instruction (VBI) is an effective means to teach employment skills to young adults with intellectual and developmental disabilities (IDD). Within the category of VBI, video prompting (VP) is well-suited to teach multistep routines, and video modeling (VM) is better suited for social interactions. In this multiple probe design, three…

We used a single case concurrent multiple probe across participants design to evaluate the effects of a multi-component intervention package on the number of correct sentences used when writing about a story for three rural elementary students with intellectual or developmental disabilities and extensive support needs. The package was comprised of…

Purpose: This study aims to investigate the learning potential of French-speaking children, either with typical development (TD) or with developmental language disorder (DLD), when learning an invented inflectional morphological rule. We tested the children's performance in learning pseudomorphemes of gender and number with dynamic assessment…

In this review, we summarized and meta-analyzed 35 single-case intervention studies that involved the use of multiple schedules of reinforcement with 78 individuals with intellectual and developmental disabilities. Based on Tau-U calculations, multiple schedules of reinforcement produced an overall large effect for appropriate communicative…

Background: Previous reviews did not include sources that were published in the last 14 years, indicating a need for an updated synthesis on the time delay literature. Objectives: This review was designed to synthesize outcomes for studies assessing time delay prompting procedures for teaching young children. Data sources: PsycINFO and ProQuest…

Individuals engage in purchasing skills on a daily basis. Regardless of the curricular focus of secondary students with intellectual and developmental disabilities (IDD; i.e., academic or functional), possession of life skills is important. In this single case design study, researchers examined the provision of online instruction to three U.S.…

Prior research has examined interventions to prevent prompt dependence from occurring during the training of novel skills. Nevertheless, the relative efficacy and efficiency of different intervention procedures may be idiosyncratic across learners, suggesting the potential benefit of an individualized assessment. The purpose of the current study…

Evidence-based strategies for play, such as the application of systematic prompting techniques, require education and collaboration between occupational therapists and classroom educators to support implementation and carryover. Educating teachers and paraprofessionals regarding systematic prompting strategies to increase play within the classroom…

Individuals with intellectual and developmental disabilities (IDD) often have difficulties with self-management skills such as scheduling daily tasks for educational, vocational, and leisure purposes. In this study, we used a multiple probe across participant design to evaluate the effects of constant time delay in teaching young adults with IDD…

The authors of this study examined a virtually delivered multimedia expository writing strategy via a single case multiple-baseline across participants design with three college students enrolled in a postsecondary program for students with intellectual and developmental disabilities. Participants responded to expository essay prompts at the…

We examined the efficacy of a combined electronic essay writing and editing mnemonic driven strategy with 24 college students in a two-year postsecondary program for students with developmental disabilities. We used a pre-posttest experimental design with random assignment to treatment/control groups. During 26 sessions each consisting of 50 min.,…

Lag reinforcement schedules have been shown in previous research to be an effective intervention for teaching verbal and nonverbal response variability to individuals with developmental disabilities. In more recent research, variability itself has been considered a reinforceable behavior in its own right (Susa & Schlinger, The Analysis of…

Adults with intellectual disability may not learn safety skills needed to maintain the safety of those within their communities. Basic life-saving skills are valued by community members and increase independent and integrated living and employment opportunities. This study used an instructional package consisting of modeling, task analysis, and…

Job coaches are not typically trained to implement systematic instructional strategies to teach vocational skills to students with intellectual and developmental disabilities (IDD). This study replicated and expanded the evaluation of a job coach behavioral skills training program designed by Brock et al. (2016) to teach participants to implement…

This study described the ability of five children with Developmental Language Disorder (DLD) to relate the mental states of story characters in two conditions: spontaneous story generation and in response to direct questions. Children spontaneously generated stories from wordless picture books. Subsequently, they were prompted, "What was…
