Teaching Children with Autism Spectrum Disorder to Answer Questions Using an iPad-Based Speech-Generating Device.

This study investigated whether a systematic instruction package was effective in child acquisition of question answering using an iPad-based speech generating device (SGD). The study was conducted with two children with autism using a multiple probe across behaviors design. Results demonstrated that the systematic instruction package consisting of graduated guidance, discrete trial teaching, time delay, and reinforcement resulted in acquisition of answering all questions. Follow-up data were collected one, three, and five weeks after instruction ended. For all participants, skills maintained during follow-up and generalized to novel settings and skills. Social validity data were also collected and indicated that teachers without experience using SGDs found them to be effective and feasible for teaching communication skills.

Online Literacy Instruction for Young Korean Dual Language Learners in General Education.

English language development is a critical component for young children's school readiness. In this study, we examined the effect of Read it again-Pre-K! (Justice and McGinty in Read it again!-Prek: a preschool curriculum supplement to promote language and literacy foundations, Crane Center for Early Childhood Research and Policy, Columbus, 2013), a literacy curriculum designed to prepare young children's school readiness on the English literacy skills of Korean dual language learners in general education. Using a multiple probe design, eight 4- to 5-year-old Korean dual language learners (1 female, 7 males) received 1:1 online synchronous daily instruction over 2 months during the summer before entering their kindergarten programs. Through the intervention, all eight children demonstrated increases in the use of English vocabulary, story comprehension, and oral fluency. Post-intervention data on vocabulary and reading fluency through three standardized tests, Dynamic Indicators of Basic Early Literacy Skills, Peabody Picture Vocabulary Test, and Expressive Vocabulary Test, showed improvement over baseline for most children. Discussion and implications for future research were provided.

Effects of telehealth-mediated behavioral assessments and interventions on client outcomes: A quality review.

The purpose of this review was to evaluate the quality of research focused on the effects of telehealth-mediated behavior-analytic assessments and interventions on client outcomes. The majority of studies utilized a single-case methodology (n = 44; 81%), while 10 studies (19%) used a group design. Of the 246 single-case designs, 99 (40%) met design standards with or without reservation. For the 10 group design studies, 7 (70%) met the design standards. When evaluating the evidence offered according to the prime independent variable (e.g., behavior assessment, intervention designed for behavior reduction, and intervention designed to establish or strengthen behavior), the literature supports the use of telehealth to conduct behavior assessments and provide interventions designed to establish or strengthen behavior. Additional research is necessary to establish the use of telehealth to conduct interventions designed for behavior reduction. Implications for future research and practice are discussed.

A comparison of single-case evaluation tools applied to functional communication training with augmentative and alternative communication supports for students with developmental disabilities.

BACKGROUND: Students with developmental disabilities frequently present with both limited vocal speech and challenging behavior. Functional communication training (FCT) with augmentative and alternative communication (AAC) supports, is a commonly recommended intervention to reduce challenging behavior for these students, while also increasing appropriate communication. AIMS: Current research on this topic has not applied multiple evaluation tools, despite the recent suggestion to do so. Further, there are limited studies in the field of special education that have (a) applied multiple evaluation tools and (b) compared the results of the tools. METHOD: In the current review, we applied three evaluation tools to intervention studies examining the use of FCT with AAC supports in school-based settings to determine the current level of scientific support for this intervention. We identified 38 studies, which contained 59 single-case designs (SCDs). Next, we compared the methodological rigor and/or quality, outcome scores, and Evidence-Based Practice (EBP) ratings provided by the three evaluation tools. RESULTS AND CONCLUSION: Our results yielded inconsistent methodological rigor and/or quality, participant outcome measures, and EBP classifications between the evaluation tools. No two evaluation tools completely aligned. Limitations and future research are discussed.

A Meta-analysis of Challenging Behavior Interventions for Students with Developmental Disabilities in Inclusive School Settings.

Challenging behavior is a significant barrier in accessing the general education curriculum for students with developmental disabilities. This necessitates the identification of evidence-based practices for addressing challenging behavior in inclusive settings. The purpose of our meta-analysis is to (a) quantify the magnitude of effect of interventions targeting the reduction of challenging behavior in students with developmental disabilities in inclusive educational settings and (b) determine if participant and intervention characteristics moderate intervention effects. A systematic search of academic databases was conducted to identify studies, which were evaluated for methodological rigor and analyzed for effects using Tau-U. Results indicate a strong overall effect of .94 (95% CI [.87, 1]) and moderating variables associated with behavior topography, interventionist, and intervention components were identified.

Interventionist Acquisition of Incidental Teaching Using Pyramidal Training via Telehealth.

We investigated the effects of a telehealth pyramidal training package on participants' implementation of incidental teaching. A total of eight adults worked with eight children with autism. Coaches were first taught to implement incidental teaching and then taught subsequent interventionists. The training package consisted of an online module and delayed video-based feedback provided via videoconferencing. Following the telehealth training program, coaches and interventionists reached the preset performance criteria and implemented incidental teaching with high fidelity. All of the child participants increased mands above baseline levels. Results suggest that interventionists can be trained via telehealth in behavior analytic interventions.

The Effects of a Shared Reading Intervention on Narrative Story Comprehension and Task Engagement of Students with Autism Spectrum Disorder.

The purpose of this study was to investigate the effects of a shared reading intervention on narrative story comprehension and task engagement of students with autism spectrum disorder (ASD). A single-case multiple baseline design was used, and three elementary-aged students with ASD participated in this study. The shared reading intervention included before, during, and after reading strategies (i.e., topic anticipation, dynamic reading, story retelling). Results of this study indicated that all participants demonstrated noticeable improvements in reading comprehension. Despite the longer duration of intervention sessions as compared to baseline sessions, participants showed similar or better task engagement with intervention. Improved reading outcomes were maintained at follow up for all participants. Implications for practical implementation and future research were discussed.

A systematic quality review of high-tech AAC interventions as an evidence-based practice.

Although high-tech augmentative and alternative communication (AAC) is commonly used to teach social-communication skills to people with autism spectrum disorder or intellectual disabilities who have complex communication needs, there is a critical need to evaluate the efficacy of this approach. The aim of this systematic review was to evaluate the quality of single-case experimental design research on the use of high-tech AAC to teach social-communication skills to individuals with autism spectrum disorder or intellectual disabilities who have complex communication needs, to determine if this intervention approach meets the criteria for evidence-based practices as outlined by the What Works Clearinghouse. Additionally, information on the following extended methodological standards is reported on all included studies: participant description, description of setting and materials, interventionist description, baseline and intervention description, maintenance, generalization, procedural integrity, and social validity. The results from 18 multiple-baseline or multiple-probe experiments across 17 studies indicate that using high-tech AAC to teach social-communication skills to individuals with autism spectrum disorder or intellectual disabilities and complex communication needs can be considered an evidence-based practice, although the review of comparison (i.e., alternating treatment) design studies did not indicate that high-tech AAC is significantly better than low-tech AAC.

Trial-Based Functional Analysis Informs Treatment for Vocal Scripting.

Research on trial-based functional analysis has primarily focused on socially maintained challenging behaviors. However, procedural modifications may be necessary to clarify ambiguous assessment results. The purposes of this study were to evaluate the utility of iterative modifications to trial-based functional analysis on the identification of putative reinforcement and subsequent treatment for vocal scripting. For all participants, modifications to the trial-based functional analysis identified a primary function of automatic reinforcement. The structure of the trial-based format led to identification of social attention as an abolishing operation for vocal scripting. A noncontingent attention treatment was evaluated using withdrawal designs for each participant. This noncontingent attention treatment resulted in near zero levels of vocal scripting for all participants. Implications for research and practice are presented.

A Systematic Review of Parent-Implemented Functional Communication Training for Children With ASD.

Supporting parents in reducing challenging behavior of children with autism spectrum disorder (ASD) requires the identification of effective, feasible, and sustainable interventions. Functional communication training (FCT) is one of the most well-established interventions in the behavioral literature and is used increasingly by parents. However, there is a need for additional evaluation of the literature related to parent-implemented FCT. In the present review, we identified 26 peer-reviewed studies on parent-implemented FCT. We conducted systematic descriptive and social validity analyses to summarize the extant literature. Across studies, parent-implemented FCT was effective in reducing child challenging behavior, and in some cases, intervention outcomes maintained and generalized to novel settings and implementers. However, few studies reported fidelity data on parent implementation of FCT, and data regarding sustained use of FCT by parents were limited. Results of the social validity analysis indicate that while FCT is often implemented by natural change agents in typical settings, parent training is often provided by professionals not typically accessible to parents. These findings suggest that future research is warranted in the areas of parent training and long-term sustainability of parent-implemented FCT.

High-technology augmentative and alternative communication for individuals with intellectual and developmental disabilities and complex communication needs: a meta-analysis.

The use of mobile technology is ubiquitous in modern society and is rapidly increasing in novel use. The use of mobile devices and software applications ("apps") as augmentative and alternative communication (AAC) is rapidly expanding in the community, and this is also reflected in the research literature. This article reports the social-communication outcome results of a meta-analysis of single-case experimental research on the use of high-tech AAC, including mobile devices, by individuals with intellectual and developmental disabilities, including autism spectrum disorder. Following inclusion determination, and excluding studies with poor design quality, raw data from 24 publications were extracted and included 89 A-B phase contrasts. Tau-U nonparametric, non-overlap effect size was used to aggregate the results across all studies for an omnibus and moderator analyses. Kendall's S was calculated for confidence intervals, p-values, and standard error. The omnibus analysis indicated overall low to moderate positive effects on social-communication outcomes for high-tech AAC use by individuals with intellectual and developmental disabilities.

A comparison of general and explicit delay cues to reinforcement for tangible-maintained challenging behaviour.

OBJECTIVES: This compares effects of explicit delay cue to reinforcement to general delay cue to reinforcement when attempting to decrease tangible-maintained challenging behaviours of children with autism spectrum disorder (ASD). METHODS: Two school-age children with ASD participated in this study. In order to evaluate the effects of a general cue versus an explicit cue on the participants' tangibly maintained challenging behaviours, a multiple baseline design across settings with an embedded alternating treatments design was used. RESULTS: Results suggested that both types of delay cue to reinforcement demonstrated effectiveness on decreasing tangible-maintained behaviours of the participant. For both participants, an explicit delay cue demonstrated slightly better effects on the participants' challenging behaviours then a general delay cue. CONCLUSIONS: This study adds an evidence to support that delayed reinforcement can be used as an effective strategy to reduce both escape and tangible-maintained challenging behaviours of children with ASD across multiple settings.
