The purposes of this review were to (a) use meta-analytic procedures to examine the effectiveness of single-case AAC intervention research on challenging behaviors exhibited by individuals with disabilities, (b) identify study characteristics that moderate intervention effects, and (c) evaluate the quality of research. The authors provided inferential and descriptive analyses of 54 studies representing 111 participants and estimated effect sizes using the Nonoverlap of All Pairs (NAP) method. Overall, AAC interventions were found to be equally effective across a broad spectrum of participants and interventions. AAC interventions were more effective with younger children than with adults. Interventions in which functional behavior assessments (FBA) were used had significantly larger effect sizes than those that did not use FBAs. Further, functional communication training interventions resulted in larger effect sizes than Picture Exchange Communication System interventions. Descriptive analysis revealed that (a) interventions often occurred in atypical environments (e.g., therapy room, experimental room) and with atypical interventionists (e.g., therapists, researchers), and (b) numerous studies did not exhibit quality characteristics of single-case research.

The Support Needs Assessment and Problem-Solving (SNAP) process is intended to assist educational teams in identifying and implementing supports for children with intellectual disability and related developmental disabilities (ID/DD) in K-12 schools. Each phase of the SNAP process is described, including identification of high priority support needs based on information derived from the Supports Intensity Scale–Children's Version (SIS-C). Two case studies of school teams using the SNAP process to identify and implement supports that enhanced opportunities for learning and participation of children in inclusive settings are presented. The importance of understanding children with ID/DD by their support needs and implications for team planning in K-12 schools are discussed.

Progress in including students with the most significant cognitive disabilities in general education environments has been unquestionably slow during the past quarter century. Systematic approaches to identifying and arranging supports are needed to accelerate this outcome. In this article, we propose an approach to understanding students by their support needs in relation to curricular demands, instructional strategies, and participation requirements as a means to enhance the capacities of schools and general education classrooms to educate all students.

The purpose of this study was to evaluate the effects of workshops and coaching on paraprofessional implementation of function-based interventions. The results of indirect and direct functional behavior assessment guided the development of intervention strategies for three students with autism and intellectual disability. Following intervention, students' appropriate behavior increased and challenging behavior decreased. In general, paraprofessionals implemented strategies with high levels of fidelity and judged both the coaching and workshop training procedures and student intervention strategies as socially valid. Implications for practice, limitations, and suggestions for future research are discussed.

This study heeds a decade-long call to action to examine the accessibility of Schoolwide Positive Behavioral Interventions and Supports (SWPBIS) for students with severe disabilities. To improve the accessibility of SWPBIS, Universal Design for Learning (UDL) and evidence-based practices were used to teach three students with severe disabilities schoolwide behavior expectations in inclusive schoolwide settings. Special education teachers from three different elementary schools adapted their campus SWPBIS Tier 1 lesson plans with additional visual supports, social narratives, and systematic instructional procedures. All participants showed improvement as evidenced by a reduction in the duration of their problem behavior in schoolwide settings. Implementing teachers found the intervention and corresponding materials to be socially valid.

Structured abstract: Introduction:This study evaluated the effectiveness of a workshop and follow-up coaching sessions on the implementation of the system of least prompts procedure by classroom team members and explored whether this intervention resulted in personal hygiene skill acquisition by a male high school student with comorbid visual impairment and autism spectrum disorder. Methods: Implementation fidelity data were analyzed descriptively through visual analysis. A multiple baseline design across behaviors was utilized to evaluate the effectiveness of the system of least prompts procedure on student skill acquisition. Results: Implementation fidelity was high and increased over the course of the study: paraeducator 1: 93.9% (range, 70 to 100%); paraeducator 2: 78.2% (range, 11 to 90%); and special education teacher: 94.1% (range, 35 to 100%). In addition, the student's independent performance improved from baseline to intervention across each targeted skill, with Tau-U scores as follows: cleaning the augmentative and alternative communication device: 0.78; washing hands: 0.76; and brushing teeth: 0.92. Classroom team members found both the training procedures and the system of least prompts intervention to be of value and effective. Discussion: During intervention, classroom team members implemented the system of least prompts with fidelity and the student mastered each skill. These results are promising and add to the significantly limited literature on instructional interventions for students with comorbid visual impairment and autism spectrum disorder. Implica tions for practitioners: Classroom team members can effectively be taught to use the system of least prompts with students with comorbid visual impairment and autism spectrum disorder. Furthermore, the intervention might be used to increase inde pendent functioning for students with these comorbid conditions.

The purpose of this meta-analysis was to summarize single-case intervention research studies in which students with disabilities received function-based intervention (FBI) within inclusive school settings to address challenging behavior. A total of 27 studies were identified and systematically reviewed to determine the overall effect of FBI on challenging and appropriate behavior and whether study characteristics moderated intervention outcomes. In addition, we summarized the following: (a) characteristics of study participants and settings, (b) characteristics of FBI applied within the studies, and (c) quality of the studies. Overall, FBI led to improved behavior in a variety of inclusive school settings. Interventions delivered after a teacher-administered functional behavior assessment and within the context of a whole group instructional arrangement resulted in significant reductions in challenging behavior and improvements in appropriate behavior, respectively. Implications for practice, future directions for research, and limitations are described. Keywords function-based intervention, functional behavior assessment, meta-analysis, literature review, inclusion Research Question 1: What were the overall effects of FBI on challenging and appropriate behavior? Research Question 2: Did any of the study characteristics moderate intervention outcomes? Research Question 3: What were the characteristics of study participants, settings, and FBI applied within the studies? Research Question 4: What was the overall quality of the reviewed studies?
