A comprehensive review of the literature was conducted for articles published between 1993 and 2013 to evaluate the quality of the Visual Activity Schedules (VAS) literature using current evidence-based criteria developed by Horner et al. (Except Child 71:165-179, 2005). Authors sought to determine whether VAS can be considered an evidence-based practice by expanding on the findings from previous reviews. A total of 31 studies met inclusion criteria for the use of VAS to various behaviors to students with autism spectrum disorder (ASD). Of these studies, 16 met criteria for acceptable quality. Results suggest that VAS can be considered an EBP for individuals with ASD, especially when used in combination with systematic instructional procedures. VAS can be used to increase, maintain, and generalize a range of skills of individuals from preschool through adulthood in a variety of settings (e.g., general education, community). Implications for practitioners using VAS, limitations, and recommendations for future research are discussed.

Understanding text can increase access to educational, vocational, and recreational activities for individuals with autism spectrum disorder (ASD); however, limited research has been conducted investigating instructional practices to remediate or compensate for these comprehension challenges. The current comprehensive literature review expanded previous reviews and evaluated research quality using Reichow (Evidence-based practices and treatments for children with autism, pp 25-39. doi: 10.1007/978-1-4419-6975-0_2 , 2011) criteria for identifying evidence-based practices. Three questions guided the review: (a) Which approaches to comprehension instruction have been investigated for students with ASD?; (b) Have there been a sufficient number of acceptable studies using a particular strategy to qualify as an evidence-based practice for teaching comprehension across the content areas?; and (c) What can educators learn from the analysis of high quality studies? Of the 23 studies included in the review, only 13 achieved high or adequate ratings. Results of the review suggest that both response-prompting procedures (e.g., model-lead-test, time delay, system of least prompts,) and visual supports (e.g., procedural facilitators) can increase comprehension skills in content areas of ELA, math, and science. Authors conclude with a discussion of (a) research-based examples of how to use effective approaches, (b) implications for practitioners, and

Both scripted lessons and unscripted task analyzed lessons have been used effectively to teach science content to students with intellectual disability and autism spectrum disorder. This study evaluated the efficacy, efficiency, and teacher preference of scripted and unscripted task analyzed lesson plans from an elementary science curriculum designed for students with intellectual disability and autism spectrum disorder by evaluating both lesson formats for (a) student outcomes on a science comprehension assessment, (b) sessions to criterion, and (c) average duration of lessons. Findings propose both lesson types were equally effective, but unscripted task analyzed versions may be more efficient and were preferred by teachers to scripted lessons. Implications, limitations, and suggestions for future research are also discussed.

Background and aims We evaluated a naturalistic language intervention (NLI) targeting expanded forms of expressive communication (e.g., two-word phrases) for elementary-aged children with autism spectrum disorder (ASD) and/or intellectual disability (ID). This study extends the findings of a previous study that evaluated an NLI for preschool-aged children who displayed social communication delays. In the previous study, one child was considered a non-responder to the original intervention; children with similar pre-intervention profiles to the non-responder were recruited for this study to evaluate a modified version of the NLI with a new participant group. Methods The NLI was evaluated within the context of a multiple probe design across children, with sessions conducted in a public school classroom. The modifications to the NLI resulted in varying dosages of the intervention provided across sessions and children. To analyze the moderating influence of the variation in dosage, we graphed each dosage variable to allow for a formative analysis of changes within and across study conditions. Results Results indicated increases in the target behavior for all three children when compared to probe sessions; however, for one child the consistency of changes were variable and, as such, may not be socially significant. Conclusions and implications This study extends the literature on conducting NLIs with minimally verbal children with ASD and ID in dynamic settings, like classrooms. Educators and related professionals can capitalize on natural opportunities for social communication in children who are minimally verbal but imitative by using naturalistic procedures to promote verbalizations during age-appropriate activities.

This study evaluated the effects of progressive time delay (PTD) to teach four elementary students with intellectual disability on how to self-instruct using a video activity schedule. A single-case multiple probe across participants design with a multiple probe across environments design for each participant was used to assess the generalization of the self-instruction behavior to novel environments. All participants acquired the self-instruction behavior in their target environments. One participant generalized this behavior to a novel environment by the completion of the study, and the other three participants required introduction of the independent variable (PTD) to master acquisition in the two generalization environments. Implications for practitioners and suggestions for effective programming of generalization in future research are discussed.

As increasing literature emerges to address text comprehension deficits for students with autism spectrum disorder (ASD), educators often struggle to design interventions resulting in successful generalization of comprehension skills. This evaluative review of literature explored the inclusion of and methods used in generalization of text comprehension research for students with ASD. Authors examined 32 studies across content areas (e.g., English language arts [ELA], math, science) to investigate the following questions: (a) To what extent is generalization addressed across content areas for students with ASD? (b) How did the studies program for generalization? (c) What conclusions can be inferred about effective generalization methods? and (d) Can quality indicators be recommended for generalization methods for text comprehension? Recommendations for quality indicators for generalization measures and strategies are suggested based on the findings from the current review. Implications for future research and instructional practice are also discussed.
