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…

Torske, Tonje; Naerland, Terje; Quintana, Daniel S.; Hypher, Ruth Elizabeth; Kaale, Anett; Høyland, Anne Lise; Hope, Sigrun; Johannessen, Jarle; Øie, Merete G.; Andreassen, Ole A. – Journal of Autism and Developmental Disorders, 2023
Girls and boys might differ in autistic symptoms and associated cognitive difficulties such as executive function (EF). We investigated sex differences in the relationship between parent rated EF and autistic symptoms in 116 children and adolescents (25 girls) aged 5-19 years with an intelligence quotient above 70 and an autism spectrum disorder…

Shea, N.; Payne, E.; Russo, N. – Journal of Autism and Developmental Disorders, 2018
Individuals with ASD often display externalizing behaviors, which have been associated with lower quality of life in adulthood. Social difficulties have been hypothesized to underlie externalizing problems among individuals with ASD (Klin and Volkmar in "Asperger Syndrome," 340-366, 2000), but this has never been tested empirically. We…

Royston, R.; Oliver, C.; Moss, J.; Adams, D.; Berg, K.; Burbidge, C.; Howlin, P.; Nelson, L.; Stinton, C.; Waite, J. – Journal of Autism and Developmental Disorders, 2018
This study describes the profile of repetitive behaviour in individuals with Williams syndrome, utilising cross-syndrome comparisons with people with Prader-Willi and Down syndromes. The Repetitive Behaviour Questionnaire was administered to caregivers of adults with Williams (n = 96), Prader-Willi (n = 103) and Down (n = 78) syndromes. There were…

Many neurodevelopmental disorders (NDDs) share common learning and behavioural impairments, as well as features such as dysregulation of the oxytocin hormone. Here, we examined DNA methylation (DNAm) in the 1st intron of the oxytocin receptor gene, "OXTR," in patients with autism spectrum (ASD), attention deficit and hyperactivity (ADHD)…

Channell, Marie Moore; Hahn, Laura J.; Rosser, Tracie C.; Hamilton, Debra; Frank-Crawford, Michelle A.; Capone, George T.; Sherman, Stephanie L. – Journal of Autism and Developmental Disorders, 2019
We examined autism spectrum disorder (ASD) risk in a large national sample of 203 individuals with Down syndrome, 6-25 years old, to determine the association of ASD risk with age, sex, IQ, adaptive behaviors, and maladaptive behaviors. We used a two-pronged approach by (1) considering ASD symptomatology continuously across the sample of…

Fenning, Rachel M.; Baker, Jason K.; Moffitt, Jacquelyn – Journal of Autism and Developmental Disorders, 2018
Difficulties regulating emotion have been linked to comorbid psychopathology in children with autism spectrum disorder (ASD), but little empirical work has examined predictors of dysregulation in this population. Forty-six families of children with ASD participated in a laboratory visit that included direct measurement of children's IQ, ASD…

Harstad, Elizabeth B.; Fogler, Jason; Sideridis, Georgios; Weas, Sarah; Mauras, Carrie; Barbaresi, William J. – Journal of Autism and Developmental Disorders, 2015
Controversy exists regarding the "DSM-5" criteria for ASD. This study tested the psychometric properties of the "DSM-5" model and determined how well it performed across different gender, IQ, and "DSM-IV-TR" sub-type, using clinically collected data on 227 subjects (median age = 3.95 years, majority had IQ > 70).…

Although autism spectrum disorder (ASD) is associated with significant mental health concerns, little is known about suicidality, particularly among youth. To address this critical gap in the literature, the current study examined the predictive validity of (1) demographics, (2) core autism symptoms, (3) cognitive abilities and adaptive behavior,…

Ruble, Lisa; McGrew, John H.; Wong, Venus; Adams, Medina; Yu, Yue – Journal of Autism and Developmental Disorders, 2019
The school, student and family factors underlying poor postsecondary outcomes of students with autism spectrum disorder (ASD) are not well understood. The potential impact of school [e.g., transition planning quality (TPQ)], family (e.g., parent activation), and student factors (e.g., adaptive functioning) and their interaction (e.g.,…

Berkovits, Lauren; Eisenhower, Abbey; Blacher, Jan – Journal of Autism and Developmental Disorders, 2017
There has been little research connecting underlying emotion processes (e.g., emotion regulation) to frequent behavior problems in young children with autism spectrum disorder (ASD). This study examined the stability of emotion regulation and its relationship with other aspects of child functioning. Participants included 108 children with ASD,…

VanderLaan, Doug P.; Leef, Jonathan H.; Wood, Hayley; Hughes, S. Kathleen; Zucker, Kenneth J. – Journal of Autism and Developmental Disorders, 2015
Gender dysphoria (GD) and autism spectrum disorder (ASD) are associated. In 49 GD children (40 natal males), we examined ASD risk factors (i.e., birth weight, parental age, sibling sex ratio) in relation to autistic traits. Data were gathered on autistic traits, birth weight, parents' ages at birth, sibling sex ratio, gender nonconformity, age,…

We examined spontaneous attention orienting to visual salience in stimuli without social significance using a modified Dot-Probe task during functional magnetic resonance imaging in high-functioning preadolescent children with Autism Spectrum Disorder (ASD) and age- and IQ-matched control children. While the magnitude of attentional bias (faster…

Siegel, Matthew – Journal of Autism and Developmental Disorders, 2018
Research on individuals severely affected by autism, including those who are minimally verbal, have intellectual disability or challenging behaviors, has become less common. The Autism Inpatient Collection (AIC) was initiated so data on this group is available to the research community. Ten studies utilizing phenotypic data from the first 350 AIC…

Correia, F.; Café, C.; Almeida, J.; Mouga, S.; Oliveira, G. – Journal of Autism and Developmental Disorders, 2015
Autism spectrum disorder (ASD) is characterized by impaired social interaction and communication, restricted interests and repetitive behaviors. Fragile X E is associated with X-linked non-specific mild intellectual disability (ID) and with behavioral problems. Most of the known genetic causes of ASD are also causes of ID, implying that these two…
