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…

Emotion knowledge has not been explored in children with cerebral palsy (CP). To evaluate differences in emotion knowledge between children with CP and their typically developing peers (TDP), and explore its associations with affective regulation and behavioral psychopathology. 36 Children with CP and 45 TDP completed the Emotion Matching Task…

Problems with emotion regulation and behavior are often reported in children with autism spectrum disorders (ASD). This pilot study examined the effect of physical exercise on emotion regulation and behavioral functioning in children with ASD. Twenty-seven children aged 8-12 years were randomized into either an exercise intervention group (n = 15)…

In March 2020, many schools were closed to prevent the spread of COVID-19 in Japan, and it is predicted that many children, especially those with neurodevelopmental disorders (NDDs), will be affected emotionally and behaviorally. Here, we examined the impact of school closures due to COVID-19 on school-aged children with NDDs using the Child…

ASD symptomology and behavioral problems pose challenges for children with ASD in school. Disagreement between parents and teachers in ratings of children's behavior problems may provide clinically relevant information. We examined parent-teacher disagreement on ratings of behavior problems among children with ASD during the fall and spring of the…

This study evaluated the magnitude of informant agreement and predictors of agreement on behavior and emotional problems and autism symptoms in 403 children with autism and their typically developing siblings. Parent-teacher agreement was investigated on the "Child Behavior Checklist" (CBCL) and "Social Responsiveness Scale"…

The Aberrant Behavior Checklist (ABC) is a widely used measure in autism spectrum disorder (ASD) treatment studies. We conducted confirmatory and exploratory factor analyses of the ABC in 1,893 children evaluated as part of the Autism Treatment Network. The root mean square error of approximation was .086 for the standard item assignment, and in…

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…

Path analysis within a structural equation modeling framework was employed to examine the relationships between two types of parent stress and children's externalizing and internalizing behaviors over a 4-year period, in a sample of 184 mothers of young children with autism spectrum disorder. Parent stress was measured with the Parenting Stress…

This study examined the factor structure of the Repetitive Behavior Scale-Revised (RBS-R) in a sample of 287 preschool-aged children with autism spectrum disorder (ASD). A confirmatory factor analysis was used to examine six competing structural models. Spearman's rank order correlations were calculated to examine the associations between factor…

Studies on the distinction between Autistic Disorder (AD) and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) have been inconclusive. This study examined the validity of PDD-NOS by comparing it to AD and other developmental disorders (DD) on parent-reported behavior problems. Fifty-four children with PDD-NOS were individually…

Research regarding the behavioral aspects of children with Rubinstein-Taybi syndrome (RTS) has suggested some possible behavioral patterns including autistic features. Caregivers of 39 children (mean age = 8.4 years) with RTS (49% showing abnormality in "CREBBP" gene) and 39 children (mean age = 8.6 years) matched on developmental level,…

This study examined stress-support in 42 families of 3- to 18-year-old children with Prader-Willi Syndrome. While children's age, intelligence quotient, and degree of obesity were not related to familial stress, families experienced greater stress when children showed more behavior problems overall, more externalizing and internalizing problems,…
