Sleep problems are prevalent in children with neurodevelopmental disabilities and are associated with the expression of restricted and repetitive behaviors (RRBs). Children (n = 57) with autism spectrum disorder (ASD, n = 38) or developmental delay (DD, n = 19) participated in multiple assessments of intellectual ability, ASD symptoms, and RRBs (3…

Introduction: Children with developmental delays (DD), particularly autism spectrum disorders (ASD), are at high risk for increased levels of behavior problems and developing internalizing problems. While previous literature has highlighted the impact of parental stress on the development of behavioral problems broadly in children with DD,…

Background: This study examined the severity of parenting stress and depressive symptoms in Taiwanese mothers of young children with autism spectrum disorder (ASD) compared to mothers of young children with developmental delay (DD). The associations between parenting stress, depressive symptoms, and children's behavioural problems were also…

Among individuals with autism spectrum disorder (ASD) who have a history of parent-reported developmental regression, or early skill loss, little is known about core-ASD symptoms (i.e., social communication, restricted/repetitive behaviors) and emotional/behavioral (E/B) symptoms during the school-age years. Study aims were to investigate whether…

To compare gastrointestinal (GI) problems among children with: (1) autism spectrum disorder (ASD), (2) developmental delay (DD) and (3) typical development (TD), GI symptom frequencies were obtained for 960 children from the CHildhood Autism Risks from Genetics and Environment (CHARGE) study. We also examined scores on five Aberrant Behavior…

This study was designed to examine the effects of literacy-based behavioural interventions (Bucholz et al., 2008) to decrease acts of physical aggression with kindergarten and first grade students. The study used a multiple baseline design across three participants. The results showed a decrease in acts of physical aggression by students with…

This study compares two service delivery models (community-based and centre-based), examining them in light of children's adaptive and maladaptive behaviours, and parental perceptions of stress and of care. More specifically, parents of 96 children with developmental delays assessed their children's adaptive and maladaptive behaviours and rated…

The goals of our study were to (a) compare agreement between autism spectrum disorder diagnosis and outcome of the Modified Checklist for Autism in Toddlers and Parents Evaluation of Developmental Status in a sample of toddlers and (b) examine specific concerns noted for toddlers who screened negative on the Modified Checklist for Autism in…

Rehabilitation professionals working with students with disabilities and the families of those students face unique challenges in providing inclusive services to special education student populations. There needs to be a focus on adaptive teaching methods that provide quality experience for students with varying disabilities to promote student…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, tested approaches for improving early screening…

Assessment of children's restricted and repetitive behaviours offers potential opportunities to improve early diagnosis of autism spectrum disorder (ASD) and timely access to interventions and support. To facilitate this requires understanding of the phenomenology of repetitive behaviours in ASD, including differentiating behaviours seen in ASD…

We examined the effectiveness and efficiency of 2 instructional arrangements using progressive prompt delay (PPD) with 3 young children with autism and 1 child with developmental delays. Specifically, we compared PPD with instructive feedback (IF) to PPD without IF in an adapted alternating treatment design. The results suggested that (a) children…

This study investigated differences in co-occurring diagnoses made in females compared to males with autism spectrum disorders in 913 children (746 males and 167 females) living in the United States with a current autism spectrum disorder diagnosis identified via caregiver-reported data from the National Survey of Children's Health 2007. The…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the complex causes of autism and potential risk factors, studied clues that could lead to earlier diagnosis, and evaluated promising…

Functional analyses that were conducted in two settings (playground and classroom) indicated that problem behavior was sensitive to adult attention on the playground and tangible items in the classroom. Attention- and tangible-based interventions were designed based on the results from each of the assessment environments and were compared. The…
