For students with Autism Spectrum Disorders and intellectual disability, the need for scientific literacy is further complicated by the need for individualized instruction necessary to teach new skills, especially when those skills are academic. This study investigated the effects of embedded, computer-assisted explicit instruction to teach…

A multiple mediation model was proposed to integrate core concepts of challenging behaviors with autistic traits to increase understanding of their relationship to quality of life (QoL). It was hypothesized that QoL is a possible mediator between the severity of challenging behaviors and autistic traits in adults with intellectual disability.…

Children with autism spectrum disorder (ASD) have particular difficulty with behavioral flexibility, but the knowledge base on behavioral flexibility in children with a diagnosis of ASD plus intellectual disability (ID) compared to children with ID only is still scarce. The aim of the present study was to assess behavioral flexibility in 111…

Burnout has been considered important to understand the well-being of people who work with individuals with intellectual disabilities (ID) and developmental disabilities (DD). To identify personal and workplace characteristics associated with burnout, this study aimed to utilize the Chinese version of the Copenhagen Burnout Inventory to provide a…

Second-generation antipsychotics (SGAs) induce frequent adverse effects in children and adolescents with each compound appearing to have a specific adverse effect profile. Aripiprazole and risperidone are FDA-approved medications for behavioral disturbances associated with autism and/or intellectual disabilities (ID) in children and adolescents.…

The current study investigated comorbidity in eighty-nine children and adolescents with Autism Spectrum Disorder in Ireland. Comorbidity is the presence of one or more disorders in addition to a primary disorder. The prevalence of comorbid psychological disorders, behaviours associated with comorbid psychopathology, epilepsy, gastrointestinal…

This study assessed the validity of the Social Communication Questionnaire (SCQ) in a sample of 69 adults, aged 18-40 years old. Participants included 21 adults diagnosed with an autism spectrum disorder (ASD) and intellectual disability (ID), and 48 individuals diagnosed with ID and no diagnosis of an ASD. The SCQ yielded a sensitivity of 0.71…

Agreement between the DSM-5, DSM-IV, and Checklist for Autism Spectrum Disorder was assessed in 125 children with autism spectrum disorder (ASD), which included high and low functioning autism (HFA and LFA) and pervasive developmental disorder not otherwise specified (PDDNOS), and children with other clinical disorders (e.g., ADHD, mental…

Aims: This study examined parental perspectives on the importance and likelihood of future adult outcomes for children with Autism Spectrum Disorders (ASD), Intellectual Disabilities (ID), or Multiple Disabilities (MD) and some of the factors that may affect parental aspirations. Methods: Parents of 105 children with ASD, ID, or MD were presented…

To determine maternal stress and child variables predicting maternal stress, 104 mothers of children with autism spectrum disorder (ASD) and intellectual disability (ID) completed the Dutch version of the Parental Stress Index (PSI; De Brock, Vermulst, Gerris, & Abidin, 1992) every six months over a period of two years. The level of maternal…

There is a significant increase in the prevalence of autism and autism spectrum disorders (ASD) in children with estimates now reaching 1 in 110 children in the United States. Families report difficulties in finding services for their young and adult children. Many adults with ASD receive services and supports through state intellectual and…

The "Autism Spectrum Disorders-Diagnosis for Adults" ("ASD-DA") is a standardized assessment used to measure autistic symptomatology in adults with intellectual disabilities (ID). In order to further establish the validity of this measure, convergent validity of the "ASD-DA" was established by comparing "ASD-DA" total and subscales scores with the…

The present study examined levels of sense-making in relation to adaptive functioning and autism symptomatology in low-functioning children with autistic disorder. Thirty-six children with autistic disorder and intellectual disability were compared with 27 children with intellectual disability and 33 typically developing children with a comparable…

The autism phenotype is associated with an excess of brain volume due in part to decreased pruning during development. Here we aimed at assessing brain volume early in development to further elucidate previous findings in autism and determine whether this pattern is restricted to idiopathic autism or shared within the autistic phenotype (fragile X…

The single-case research design has become a paradoxical methodology in the applied sciences. While various experimental designs have been in place for over 50 years, there has not been wide acceptance of single-case methodology outside clinical and school psychology, or the field of special education. These methods were developed in the U.S.A.,…
