A systematic retrospective case note review was undertaken to investigate autism diagnostic factors in 124 individuals with Sturge-Weber syndrome (SWS). Social Responsiveness Scale questionnaires were then analysed to explore the severity and profile of autism characteristics in 70 participants. Thirty-two to forty percent of participants had a…

Subtle language and communication difficulties are persistent and pervasive for autistic individuals without intellectual disability. They are thought to impact negatively on functionality, social interrelations and emotional well-being, although this relationship is under-explored in the literature. The personal accounts of autistic children…

Background: Autism spectrum disorder (ASD) and social pragmatic communication disorder (SPCD) are two neurodevelopmental disorders with many similarities in affected individuals' impairments in social-communicative and pragmatic development. A central question pertaining to their differentiation concerns whether the distinction is truly…

Sotos syndrome is a congenital overgrowth syndrome associated with intellectual disability. This study investigated communicative abilities of children with Sotos syndrome (n = 31), using the Children's Communication Checklist, second edition. A cross-syndrome approach was used to establish the specificity of these abilities. Children with…

Difficulty with communication and social functioning are two outstanding core symptoms of autism spectrum disorder, and physical activity has long been suggested to improve autism spectrum disorder symptoms. In this meta-analysis of controlled trials, we examined the effects of physical activity interventions compared to controls on communication…

Expressive incoherence can be implicated in socio-emotional communicative problems in autism spectrum disorder (ASD). The present study examined expressive incoherence in 37 children with ASD and 41 typically developing (TD) children aged 3-13 years old during a frustration task. The role of alexithymia in expressive incoherence was also assessed.…

Autistic traits and executive function (EF) were assessed in 413 typically developing children aged 6-9 years. The children were divided into the high- autistic-trait (HAT) and low-autistic-trait (LAT) groups based on their total autistic traits. Results suggested that there were gender differences in specific autistic traits in children with LAT.…

With Latent Class Analysis applied on data of 98 children with autism spectrum disorder (ASD) (9-12 years; 17 girls) participating in social skills training (SST) in a randomized controlled trial (Dekker et al. 2019), four subgroups were detected, based on social-communicative skills before, and response patterns to training. Two subgroups…

There is a lack of research on effective interventions to improve the early numeracy skills of children with severe disabilities---autism spectrum disorder, developmental disability, and intellectual disability---and complex communication needs. While preliminary research suggests the Early Numeracy curriculum is effective for teaching children…

This study was a replication of Mazefsky et al.'s ("Journal of Autism and Developmental Disabilities" 43:1236-1242, 2013) investigation among a sample of 45 high ability children and adolescents diagnosed with ASD under DSM-IV-TR. Items from the ADOS and ADI-R were mapped onto DSM-5 diagnostic criteria for ASD and SCD to determine…

The Japanese version of the Children's Communication Checklist-2 (CCC-2) was rated by caregivers in a large national population sample of 22,871 children aged 3-15 years. The General Communication Composite (GCC) of the CCC-2 exhibited a distribution with a single-factor structure. The GCC distribution between autism spectrum disorders (ASD) and…

The purpose of the current paper is to describe the impact of applied behaviour analysis on language treatment for children with autism spectrum disorders (ASDs) diagnoses. Specifically, this paper will describe Skinner's theory of verbal behaviour and its contributions to evidence-based treatments for communication deficits among individuals with…

The aim of this study was to generate a patient-centered conceptual model of the impact of living with autism spectrum disorder, which can be used to support the selection of outcome measures for clinical trials. Following an initial literature review to identify preliminary concepts and inform an interview guide, in-depth face-to-face interviews…

Children with autism spectrum disorder (ASD) require substantial support to address the core symptoms of ASD and co-occurring behavioral/developmental conditions. This study explores the early diagnostic experiences of school-aged children with ASD using survey data from a large probability-based national sample. Multivariate linear regressions…

Purpose: Impairments in the social use of language are universal in autism spectrum disorder (ASD), but few standardized measures evaluate communication skills above the level of individual words or sentences. This study evaluated the Expression, Reception, and Recall of Narrative Instrument (ERRNI; Bishop, 2004) to determine its contribution to…
