The interactions between sleep problems, autism symptoms and emotional and behavioural difficulties were explored using network analysis in 240 autistic children (mean age: 8.8 years, range 5-13 years) with moderate to severe sleep problems. Findings revealed a highly connected and interpretable network, with three separate clusters identified of…

This study aimed to learn about the experiences of families of individuals with a dual diagnosis of Down syndrome (DS) and autism spectrum disorder (ASD) (DS-ASD), and to document the journey from early concerns to diagnosis and intervention. Caregivers completed an online survey describing their journey raising a child with DS-ASD. Survey…

This was an exploratory cross-sectional study comparing 45 children with ASD to 24 typically developing drug-naïve controls, group-matched on age, sex, and body mass index. Objective data was obtained using the following: an ambulatory circadian monitoring device; saliva samples to determine dim light melatonin onset (DLMO): and three…

Purpose: Autistic children are reported to display higher levels of externalizing and internalizing behaviors than neurotypical children, and their parents report more stress than parents of neurotypical children. It is unclear whether child behavior difficulties contribute to increased parenting stress, whether parenting stress contributes to…

Clinical anxiety is a common comorbidity in autistic people. Due to the prevalence of anxiety in the autism population and the adverse effects it causes, there is a critical need to develop effective interventions which address anxiety symptoms for autistic people. Therefore, the purpose of this systematic review was to examine the effectiveness…

Co-occurring emotional and behavioral problems (EBPs) frequently exist in young autistic children. There is evidence based on parental report that parenting interventions reduce child EBPs. More objective measures of child EBPs should supplement parent reported outcomes in trials. We describe the development of a new measure of child and parenting…

Long-term effects of the COVID-19 pandemic on autistic individuals and their families are recently emerging. This study investigated these effects in 40 mother-child dyads by measuring the behavioral problems of autistic individuals (via Aberrant Behavior Checklist) and their mothers' anxiety levels (via Beck Anxiety Inventory) during the…

The present study addressed the different contributors to social anxiety in children with Selective Mutism (SM), with and without co-occurring Autism Spectrum Disorder (ASD) (SM + ASD). Seventy-five parents completed an online composite questionnaire consisting of the symptoms of SM and ASD, anxiety and sensory measures. The results found the SM +…

The purpose of the study was to characterize repetitive phenomena in Williams syndrome (WS). The parents of 60 subjects with WS completed the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) or Children's Y-BOCS, the Yale Global Tic Severity Scale, the Stereotyped Behavior Scale, and the Spence Children's Anxiety Scale--Parent Version. Nineteen…

Distress caused by sensory processing differences for autistic individuals may be reduced by repetitive behaviours (RRB), including repetitive motor (RMB) and insistence on sameness (ISB) behaviours. Intolerance of uncertainty (IU) and anxiety mediate the relationship between sensory processing and RRB in autistic children. We replicated this…

Parent-mediated interventions can reduce behavioral and emotional problems in children with ASD. This report discusses the development of the first group parent intervention targeting behaviors "and" anxiety in children with ASD, across the spectrum of cognitive and language ability. 'Predictive Parenting' was developed from the clinical…

We investigated longitudinal relations between internalizing, externalizing, and total behaviors that challenge in young children on the autism spectrum and mothers' parenting stress. Participants included 93 mothers of children on the autism spectrum aged 27.89-65.84 months, who completed questionnaires on maternal parenting stress, and…

When individuals with autism and intellectual and developmental disabilities exhibit severe problem behavior, assessment and treatment are often warranted. Parents of such individuals are at high risk for developing parenting stress. In this study, 194 parents completed the Parenting Stress Index-Short Form at their child's time of admission to…

Irritability is an impairing problem in children with ASD that may be associated with other behavioral and emotional concerns. The Affective Reactivity Index (ARI) is a parent-rated measure of irritability widely used in children with mood disorders, however, its utility in children with ASD remains unclear. In this study, we examined ARI parent…

This study examined sex differences in externalizing and internalizing symptoms of children with ASD without intellectual disability (ID). The sample (n = 80) included 40 girls and 40 boys, ages 6-12 years, with ASD (without ID) matched on age and IQ. Externalizing and internalizing symptoms were significantly elevated for this sample (girls and…
