Studies have shown that there are differences between the presentations of males and females diagnosed with autism. There remains a developing understanding about how the presentation of autism differs between boys (hereafter referred to as 'assigned males at birth') and girls (assigned females at birth). This study sought to investigate the…

The newest edition of the "Diagnostic and Statistical Manual of Mental Disorders" (5th ed., DSM-5) introduced substantial changes to the diagnostic criteria for autism spectrum disorder, including new severity level ratings for social communication and restricted and repetitive behavior domains. The purpose of this study was to evaluate…

Despite extensive research examining self-management interventions for individuals with autism spectrum disorder (ASD), researchers have failed to evaluate self-management procedures for on-task behavior in the home environment or with parents as interventionists. Using an ABAB design, the present study examined the effectiveness of a…

Introduction: Youth with intellectual disabilities (ID) demonstrate higher rates of disruptive behavior disorders (DBDs) than youth with typical development (TD). DBDs such as oppositional defiant disorder (ODD) predict higher rates of delinquency during adolescence. Yet, few studies have examined risk-taking and delinquency among youth with ID.…

Anxiety often co-occurs with autism spectrum disorder, yet there are few valid and reliable instruments for measuring anxiety in youth with autism spectrum disorder. This article describes the modification of the Pediatric Anxiety Rating Scale for youth with autism spectrum disorder and systematic psychometric evaluation in a well-characterized…

Children with autism spectrum disorder exhibit significant difficulties with emotion regulation. Respiratory sinus arrhythmia is a biomarker for processes related to emotion regulation, with higher baseline rates linked to beneficial outcomes. Although reduction in respiratory sinus arrhythmia in response to challenge can index adaptive processes…

Anxiety is a common and impairing problem in children with autism spectrum disorder, but little is known about it in preschool children with autism spectrum disorder. This article reports on the characteristics of anxiety symptoms in young children with autism spectrum disorder using a parent-completed rating scale. One hundred and eighty children…

Adolescents with autism spectrum disorder frequently experience social communication difficulties, executive functioning deficits, and anxiety and depressive symptoms, which are similar to the symptoms and correlates of sluggish cognitive tempo. Although sluggish cognitive tempo is related to, but distinct from, the inattentive and…

The aim of this study was to examine the relationship between emotion dysregulation and the core features of Autism Spectrum Disorder (ASD), which include social/communication deficits, restricted/repetitive behaviors, and sensory abnormalities. An 18-item Emotion Dysregulation Index was developed on the basis of expert ratings of the Child…

This article focuses on the role the Dutch school for children with "learning and behavioural problems" (LOM) has played in knowledge production about learning disabilities and in the development of academic study of special education between 1949 and 1985. LOM-schooling grew rapidly during these years and attracted relatively many…

This study used a randomized controlled trial to compare two distinct models of group social skills interventions with adolescents with autism spectrum disorder (ASD). Participants had a confirmed diagnosis of ASD, had an IQ greater than or equal to 70, and were educated in the general education setting. Data from 62 adolescent participants who…

To date there are no evidence-based comprehensive interventions for use in school settings. There are numerous barriers to delivery of high-quality interventions in schools that have limited the transfer of research-based interventions to school settings. "Modular Approach to Autism Programing for Schools (MAAPS)" is a framework for…

Objective: Despite strong evidence that inattentive and hyperactive/impulsive behaviors are associated with mathematical difficulties in school-age children, little research has been conducted to examine the link between these constructs before the start of formal education. The purpose of this study was to examine how different manifestations of…

There is a paucity of research on psychosocial treatments for depression in adults with intellectual disability (ID). In this pilot study, we explored the efficacy of a group CBT treatment that involved a caregiver component in adults with mild ID with a depressive disorder. Sixteen adults with mild ID and a depressive disorder participated in a…

We contrasted Behavior Assessment System for Children, Second Edition--Parent Rating Scales--Preschool Form (BASC-2 PRS-P) parent ratings for 242 (52% African American; 39% White) preschool-aged children from three diagnostic groups: autism spectrum disorder (ASD), intellectual disability (ID), and ASD and ID (ASD/ID). Across diagnostic groups,…
