Direct linkBreider, Simone; Hoekstra, Pieter J.; Wardenaar, Klaas J.; van den Hoofdakker, Barbara J.; Dietrich, Andrea; de Bildt, Annelies – Journal of Autism and Developmental Disorders, 2022
We studied the association of early-life environmental and child factors with disruptive behaviors in children with autistic traits around age 7, in the Avon Longitudinal Study of Parents and Children (n = 6,401). Logistic regression with the least absolute shrinkage and selection operator indicated that disruptive behaviors were associated with…

Knutsen, John; Crossman, Morgan; Perrin, James; Shui, Amy; Kuhlthau, Karen – Autism: The International Journal of Research and Practice, 2019
Compared to the social communication domain, considerably less is known about the cause, development, and impact of restricted, repetitive behaviors interests and activities in children with autism spectrum disorder, including possible sex differences. This study examined sex differences in clinically identified (Autism Diagnostic Observation…

Nasca, Brian C.; Lopata, Christopher; Donnelly, James P.; Rodgers, Jonathan D.; Thomeer, Marcus L. – Journal of Autism and Developmental Disorders, 2020
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…

Restricted interests and repetitive behaviors (RRBs) are core symptoms of autism spectrum disorder (ASD), and commonly occur in attention-deficit/hyperactivity disorder (ADHD). Little is known about how RRBs manifest in ADHD. We quantified and compared factor structures of RRBs in children with ASD (n = 634) or ADHD (n = 448), and related factors…

Wallisch, Anna; Behrens, Sarah; Salley, Brenda; Jamison, Rene; Boyd, Brian – Journal of Autism and Developmental Disorders, 2021
Autism spectrum disorder (ASD) research is largely based on males, and females with ASD are at risk for under-identification. Research recommends listening to parent concerns since these are often predictive of a child's eventual diagnosis. This study examined how patterns of parent concerns predicted sex differences and eventual child diagnosis…

Mc Gill, Ciara; Breen, Cathal J. – British Journal of Learning Disabilities, 2020
Introduction: Adults with complex needs and severe learning disability present as a serious management problem within the community. Restrictive interventions are often used to manage adults with these issues, even though best practice recommends the use of positive behaviour support. Positive behaviour support involves functional analysis, but it…

Adaptive functioning, or the suite of skills essential for real-world, day-to-day functioning, includes daily living, communication, and socialization abilities. Even in the absence of co-occurring intellectual disability (IQ < 70), difficulties in adaptive functioning are prominent in autism spectrum disorder (ASD). Further, ASD individuals…

Nag, Heidi Elisabeth; Naerland, Terje – Journal of Intellectual Disabilities, 2021
Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations between behavioural and emotional problems, age,…

Usher, Lauren V.; DaWalt, Leann S.; Hong, Jinkuk; Greenberg, Jan S.; Mailick, Marsha R. – Journal of Autism and Developmental Disorders, 2020
This study examined trajectories of daily living skills, behavior problems, body mass index (BMI), and health conditions spanning nearly a decade in adolescents and adults with fragile X syndrome (N = 134; age range at study end = 19-49 years), examining influences of sex and autism spectrum disorder (ASD) symptoms. Hierarchical linear modeling…

Kuzminskaite, Erika; Begeer, Sander; Hoekstra, Rosa A.; Grove, Rachel – Autism: The International Journal of Research and Practice, 2020
Autism spectrum disorder and anxiety are highly comorbid conditions. Understanding the underlying traits of anxiety in autism spectrum disorder is crucial to prevent and treat it efficiently. Hence, this study determined whether social communication difficulties or restricted repetitive behaviors are stronger risk factors for anxiety symptoms in…

Flowers, Jacqueline; Lantz, Johanna; Hamlin, Terry; Simeonsson, Rune J. – Journal of Autism and Developmental Disorders, 2020
Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized…

White, Rhianna; Barreto, Manuela; Harrington, Jean; Kapp, Steven K.; Hayes, Jennie; Russell, Ginny – Autism: The International Journal of Research and Practice, 2020
Evidence suggests disclosing an autism diagnosis is associated with reduced stigmatization for autistic adults. However, it is unknown whether this is true for autistic adolescents. We used a vignette-and-questionnaire design to study stigmatizing attitudes with adolescents (aged 11-12 and 14-16 years, total N = 250) in a UK school. We…

Nah, Yong-Hwee; Tan, Julianne Wen-Li – Educational and Developmental Psychologist, 2021
Objective: It has been suggested that gender stereotypes can influence social perception and how people perceive behaviours in Autism Spectrum Disorder (ASD) based on the individual's gender. This study aimed to investigate the effect of student's gender on teachers' perceptions of ASD behaviours in regular school settings. Method: The sample…

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)…

Shivers, Carolyn M.; McGregor, Casey; Hough, Ashlea – Autism: The International Journal of Research and Practice, 2019
Despite the prevalence of studies showing increased stress among mothers of individuals with autism spectrum disorders, few studies have examined general stress among typically developing siblings. This study used an online survey to compare the levels of self-reported stress between adolescent siblings of individuals with autism spectrum disorder…
