Up to 80% of children with autism spectrum disorder (ASD) experience sleep problems, which have been associated with more severe presentations of ASD symptoms. We examined the bidirectional link between sleep problems and specific ASD symptoms at two time points within 5 years in a well-characterized sample (659 children with ASD). Using…

Despite showing effects in well-controlled studies, the extent to which early intensive behavioral intervention (EBI) produces positive changes in community-based settings remains uncertain. Thus, our study examined changes in autistic symptoms and adaptive functioning in 233 children with autism receiving EBI in a community setting. The results…

Previous research has identified possible sex-based differences in restricted and repetitive behaviors in autism spectrum disorder (ASD). However, this finding is mixed, particularly among preschool-aged children. We investigated the presence of sex-based differences in parent-rated ASD symptomatology, using the Autism Spectrum Rating Scale…

Autistic-like features and functional somatic symptoms (FSS) frequently co-occur. It remains unknown how autistic-like features and FSS affect each other and develop throughout adolescence. This study examined reciprocal relations between autistic-like features and FSS in adolescence. Participants were 2772 adolescents (52.5% male) from the…

Autism spectrum disorder is a neurodevelopmental condition characterized by deficits in social communication and repetitive behaviors. How specific anatomical alterations contribute to the clinical profile of autism spectrum disorder remains largely uncharacterized. We have previously shown that parvalbumin-positive Chandelier cells, a specific…

Parents of autistic children experience more parenting stress and are at increased risk for poor mental and physical health compared with parents of neurotypical children; however, not all parents are distressed. The present study used a person-centered analytic approach to identify profiles of the parenting experience in a sample of 183 mothers…

Background: The aim of this study was to investigate the demographic, clinical characteristics, and service systems of patients with autism spectrum disorder (ASD) and/or intellectual disability presenting to a large paediatric hospital emergency department (ED) with behaviours of concern (BOC) over a two-year period. Method: Retrospective audit…

A neurological disorder, along with several behavioral issues, may be to blame for a child's subpar performance in the academic journey (such as anxiety, depression, learning disorders, and irritability). These symptoms can be used to diagnose children with ASD, and supervised machine learning models can help differentiate between ASD traits and…

Autism Spectrum Disorder (ASD) is a developmental disorder that impacts areas of social communication and social interaction. The prevalence of ASD has increased in the last ten years. Symptoms and behaviors include restrictive and repetitive movements, highly restricted and fixated interests, insistence on sameness, and hypo or hyper-reactivity.…

This study evaluated the use of the Prevent-Teach-Reinforce (PTR) model as an intensive individualized behavior intervention. Three educators and three high school students with autism spectrum disorder participated in the study. A concurrent multiple baseline design across participants was used to demonstrate the outcomes. The results indicated…

Fragile X syndrome (FXS) is characterized by variable neurobehavioral abnormalities, which leads to difficulties in developing and evaluating treatments and in determining accurate prognosis. We employed a pediatric cross-sectional sample (1,072 males, 338 females) from FORWARD, a clinic-based natural history study, to identify behavioral subtypes…

Autistic people appear to be at increased risk of post-traumatic stress disorder, and experiences involving violence or sexual abuse appear to be common in this population. However, knowledge concerning trauma in autistic people with co-occurring intellectual disabilities is limited. In this cross-sectional study, we explored the prevalence of…

Previous studies suggest that child behavior problems were associated with higher levels of parenting stress and depressive symptoms in parents of children with autism spectrum disorder (ASD). Parents' coping strategies have been found to provide potential buffering effects. Thus, this study investigated the mediation effect of coping strategies…

There is limited literature on the association between parenting practices, parenting stress and externalising behaviours in autistic children. We investigated whether parenting practices mediate the association between parenting stress and externalising behaviours. Parents of school-aged autistic children (n = 138) completed an online survey on…

High levels of parenting stress have been detected in mothers of children with Autism (ASD) and children with attention deficit hyperactivity disorder (ADHD) comparing with mothers of typically developing (TD) children. The current study explored the implications of social support (confidant and affective support) and child characteristics…
