\"This book draws on contemporary theory and recent findings to provide researchers, professionals, undergraduate and graduate students with essential resources, allowing them to better understand and support children, youth and adults with autism and significant communication impairments. The book consists of 11 chapters organized into 3 sections detailing typical and atypical prelinguistic development for individuals on the autism spectrum, together with a range of assessment and intervention approaches that clinicians and educators can draw on in practice. The book adopts a lifespan perspective, recognizing that there is an important and particularly challenging sub-group of children on the spectrum who remain minimally verbal beyond the age of 8 years. Each chapter summarizes current research on a selected topic, identifies key challenges faced by researchers, educators and clinicians, and considers the implications for research and practice. The concluding chapter considers issues of research translation and how educators and clinicians can encourage the use of evidence-based practices for prelinguistic and minimally verbal individuals.\"--Back cover.

This investigation examined the long term effect of Karate techniques training on communication of children with autism spectrum disorders (ASD). Thirty school aged children with ASD were randomly assigned to an exercise (n = 15) or a control group (n = 15). Participants in the exercise group were engaged in 14 weeks of Karate techniques training. Communication deficit at baseline, post-intervention (week 14), and at 1 month follow up were evaluated. Exercise group showed significant reduction in communication deficit compared to control group. Moreover, reduction in communication deficit in the exercise group at one month follow up remained unchanged compared to post-intervention time. We concluded that teaching Karate techniques to children with ASD leads to significant reduction in their communication deficit.

In this pilot study, we tested the effects of a novel intervention (JASPER, Joint Attention Symbolic Play Engagement and Regulation) on 3 to 5 year old, minimally verbal children with autism who were attending a non-public preschool. Participants were randomized to a control group (treatment as usual, 30 h of ABA-based therapy per week) or a treatment group (substitution of 30 min of JASPER treatment, twice weekly during their regular program). A baseline of 12 weeks in which no changes were noted in core deficits was followed by 12 weeks of intervention for children randomized to the JASPER treatment. Participants in the treatment group demonstrated greater play diversity on a standardized assessment. Effects also generalized to the classroom, where participants in the treatment group initiated more gestures and spent less time unengaged. These results provide further support that even brief, targeted interventions on joint attention and play can improve core deficits in minimally verbal children with ASD.

The advancing social-communication and play (ASAP) intervention was designed as a classroom-based intervention, in which the educational teams serving preschool-aged children with autism spectrum disorder are trained to implement the intervention in order to improve these children’s social-communication and play skills. In this 4-year, multi-site efficacy trial, classrooms were randomly assigned to ASAP or a business-as-usual control condition. A total of 78 classrooms, including 161 children, enrolled in this study. No significant group differences were found for the primary outcomes of children’s social-communication and play. However, children in the ASAP group showed increased classroom engagement. Additionally, participation in ASAP seemed to have a protective effect for one indicator of teacher burnout. Implications for future research are discussed.

Purpose: This study aimed to explore the feasibility of a telepractice communication partner intervention for children who use augmentative and alternative communication (AAC) and their parents. Method: Five children (aged 3;4-12;9 [years;months]) with severe expressive communication impairments who use AAC and their parents enrolled in a randomized, multiple-probe design across participants. A speech-language pathologist taught parents to use a least-to-most prompting procedure, Read, Ask, Answer, Prompt (RAAP), during book reading with their children. Parent instruction was provided through telepractice during an initial 60-min workshop and five advanced practice sessions (M = 28.41 min). The primary outcome was parents' correct use of RAAP, measured by the percentage of turns parents applied the strategies correctly. Child communication turns were a secondary, exploratory outcome. Results: There was a functional relation (intervention effect) between the RAAP instruction and parents' correct use of RAAP. All parents showed a large, immediate increase in the level of RAAP use with a stable, accelerating (therapeutic) trend to criterion after the intervention was applied. Increases in child communication turns were inconsistent. One child increased his communication turns. Four children demonstrated noneffects; their intervention responses overlapped with their baseline performance. Conclusions: Telepractice RAAP strategy instruction is a promising service delivery for communication partner training and AAC interventions. Future research should examine alternate observation and data collection and ways to limit communication partner instruction barriers.

According to the available studies, mobile applications have provided significant support in improving the diverse skills of special individuals with social pragmatic communication disorder (SPCD). Over the last decade, SPCD has affected 8 to 11% of individuals, and therapy sessions cost between $50 and $150 per hour. This preliminary study aims to develop an interactive, user-friendly intervention to enhance social and emotional interaction skills in individuals with SPCD. The proposed intervention is an Android application that enhances social and emotional interaction skills. This pilot study involved 29 human subjects aged 7–13 years with pragmatic communication deficits. In a randomized controlled trial, the intervention was developed and implemented with consideration of caregiver and professional requirements. The improvement was analyzed using standard scales, including the Social Communication Questionnaire (SCQ) and the Social Communication Disorder Scale (SCDS). Moreover, the outcomes were examined through statistical parameters (mean, standard deviation) and tests ( t -test). The intervention significantly improved the social and emotional skills of individuals with deficits. Before using the intervention, the identified statistical values for SCQ (mean = 6.48 and standard deviation = 3.37) and SCDS (mean = 8.17 and standard deviation = 4.79). However, after using the intervention, values for SCQ (mean = 8.24 and standard deviation = 3.95) and SCDS (mean = 9.48 and standard deviation = 4.72) were improved in comparison to the before-intervention outcome. The evaluation of the t -scores and p -values indicates that there has been significant improvement in the performance of individuals after the successful completion of the intervention. The proposed and applied intervention resulted in a significant impact in terms of improvement in social and emotional skills. The study concluded that it allows individuals to practice social and emotional interaction skills in a structured, controlled, and interactive environment. The proposed intervention has been found acceptable as per the reviews of caregivers and professionals, based on essential criteria including user experience, usability, interactive nature, reliability, and creditability. Graphical Abstract

Aims: This study design article aims to describe a research study focused on evaluating the use of the Infant-Toddler Checklist to identify children at 18 months with early communication difficulties, and to study the ComAlong Toddler intervention for parents to support their child’s communication development. Background: Communication disorders are a common public health problem affecting up to 20% of children. Evidence points to the importance of early detection and intervention to improve young children’s communicative abilities and decrease developmental delay. Early identification of communication difficulties is possible with instruments such as Infant-Toddler Checklist. The ComAlong Toddler intervention is tailored to the needs of parents of young children with communication delay before definitive diagnosis. The parents are provided with guidance in communication enhancing strategies during home visit and five group sessions. Methods: The study uses a prospective cohort design. Children were consecutively recruited during 2015–2017, and data will be collected 2015–2023. The screening was performed at the child health centre through use of the Infant-Toddler Checklist. An assessment and first consultation were then performed by a speech and language therapist for children with suspected communication delay according to the screen as well as for children referred for other reasons before the age of 2.5 years. Children with confirmed communication delay were randomised between two interventions: the ComAlong Toddler parental course or a telephone follow-up. Outcome measures include child communication and language skills and use of augmentative and alternative communication. To gain insight into the participants’ perspectives, surveys have been collected from parents. Conclusion: The study will provide information regarding identification and intervention for 18-month old children with communication delay. Trial registration: ISRCTN13330627

Autism spectrum disorder (ASD) and social communication disorder (SCD) are neurodevelopmental disorders characterized by deficits in social communication that hinder social adaptation, with limited pharmacological options for therapy owing to the absence of identified biomarkers. Individuals with ASD or SCD require lifelong interventions tailored to their development stages. However, most existing interventions primarily focus on early childhood, leaving adolescents relatively underserved. Moreover, timely access to interventions is often limited by geographic and economic barriers as specialized clinics and therapists tend to be concentrated in major urban areas. This pilot randomized clinical trial aimed to evaluate the initial safety and efficacy of NDTx-01, a digital therapeutic (DTx) for adolescents with ASD or SCD. NDTx-01 was designed to overcome the accessibility limitations by integrating cognitive behavioral therapy principles, story-based interventions, and gamification elements. We introduce a protocol for a multicenter, prospective, assessor-blinded pilot randomized clinical trial involving children and adolescents aged 10 to 18 years diagnosed with ASD or SCD. Participant enrollment was conducted at 3 major medical hospitals. Enrolled participants were randomly assigned to either the intervention group (NDTx-01 and treatment as usual [TAU]) or the control group (TAU only). TAU included medications and therapeutic services. Participants were instructed to use the app approximately 10 minutes per day, 5 days a week. To evaluate the efficacy of NDTx-01, standardized tools were administered, including the Korean version of the Vineland Adaptive Behavior Scales, Second Edition (K-VABS-II); the Social Responsiveness Scale, Second Edition; Clinical Global Impressions-Severity (CGI-S); Clinical Global Impressions-Improvement (CGI-I); the Social Communication Questionnaire; and the Korean version of the Stress Index for Parents of Adolescents. Assessments were conducted in weeks 0, 1, 2, 4, and 6, except for K-VABS-II, CGI-S, and CGI-I, which were administered only in weeks 0, 4, and 6. Statistical analyses were conducted using the SAS software. Between-group differences were assessed using independent 2-tailed 2-sample t tests or Wilcoxon rank sum tests. Within-group changes were evaluated using paired t tests or Wilcoxon signed rank tests. From August 2024 to December 2024, a total of 42 individuals were screened, 39 (93%) participants who met the inclusion criteria were enrolled, and 1 participant withdrew consent; the remaining participants completed the study. The pilot randomized clinical trial was successfully completed, and the results were published in April 2025. As of 2025, we are conducting a confirmatory clinical trial at 5 major hospitals across South Korea. The results of this pilot clinical trial provided important insights into the initial safety and efficacy of DTx as interventions for adolescents with ASD and SCD. Both groups demonstrated statistically significant improvements in adaptive skills and socialization.
