Purpose: Restricted and repetitive behaviours are a core feature of autism diagnoses but have not been widely studied in adulthood. This study examined the rates of and associations between repetitive behaviours and sensory sensitivity in autistic and non-autistic adults; and whether repetitive behaviours described as "stimming" impacted…

Allen, Korrie; Harrington, John; Quetsch, Lauren B.; Masse, Joshua; Cooke, Cathy; Paulson, James F. – Journal of Autism and Developmental Disorders, 2023
A relatively large number of children with autism spectrum disorder (ASD) exhibit disruptive behavioral problems. While accumulating data have shown behavioral parent training programs to be efficacious in reducing disruptive behaviors for this population, there is a dearth of literature examining the impact of such programs across the range of…

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)…

Although social-communication difficulties and repetitive behaviors are hallmark features of autism spectrum disorder (ASD) and persist across the lifespan, very few studies have compared age-related differences in these behaviors between youth with ASD and same-age typically developing (TD) peers. We examined this issue using SRS-2 (Social…

Lewis, Alan S.; van Schalkwyk, Gerrit Ian; Lopez, Mayra Ortiz; Volkmar, Fred R.; Picciotto, Marina R.; Sukhodolsky, Denis G. – Journal of Autism and Developmental Disorders, 2018
Nicotinic acetylcholine receptors (nAChRs), particularly the a7 nAChR, are implicated in the pathophysiology of both autism spectrum disorder (ASD) and aggressive behavior. We explored the feasibility, tolerability, and preliminary efficacy of targeting nAChRs using transdermal nicotine to reduce aggressive symptoms in adults with ASD. Eight…

Sparapani, Nicole; Reinhardt, Vanessa P.; Hooker, Jessica L.; Morgan, Lindee; Schatschneider, Christopher; Wetherby, Amy M. – Journal of Autism and Developmental Disorders, 2022
This study examined how teachers and paraprofessionals in 126 kindergarten-second grade general and special education classrooms talked with their 194 students with autism, and further, how individual student characteristics in language, autism symptoms, and social abilities influenced this talk. Using systematic observational methods and factor…

Johnston, Kate; Murray, Kim; Spain, Debbie; Walker, Ian; Russell, Ailsa – Journal of Autism and Developmental Disorders, 2019
Studies of executive function (EF) in autism spectrum disorder (ASD) have reported mixed findings. Possible confounds include EF domain assessed and co-occurring neurodevelopmental diagnoses. EF task performance across multiple domains and everyday function of autistic adults (n = 110) was significantly different to age- and IQ-matched controls (n…

Kuravackel, Grace M.; Ruble, Lisa A.; Reese, Robert J.; Ables, Amanda P.; Rodgers, Alexis D.; Toland, Michael D. – Journal of Autism and Developmental Disorders, 2018
Despite the growing number of studies that demonstrate the importance of empowering parents with knowledge and skills to act as intervention agents for their children with autism spectrum disorder (ASD), there are limited examples of parent-mediated interventions that focus on problem behaviors. Additionally, access to ASD-trained clinicians and…

Traynor, J. M.; Gough, A.; Duku, E.; Shore, D. I.; Hall, G. B. C. – Journal of Autism and Developmental Disorders, 2019
The social communicative deficits and repetitive behaviours seen in Autism Spectrum Disorder (ASD) may be affected by altered stimulus salience and reward attribution. The present study used eye tracking and a behavioural measure to index effort expenditure, arousal, and attention, during viewing of images depicting social scenes and…

Poljac, Edita; Hoofs, Vincent; Princen, Myrthe M.; Poljac, Ervin – Journal of Autism and Developmental Disorders, 2017
Although behavioural rigidity belongs to the core symptoms of autism spectrum conditions, little is known about its underlying cognitive mechanisms. The current study investigated the role of intentional control mechanisms in behavioural rigidity in autism. Autistic individuals and their matched controls were instructed to repeatedly choose…

Magaña, Sandy; Lopez, Kristina; Salkas, Kristen; Iland, Emily; Morales, Miguel Angel; Garcia Torres, Mariana; Zeng, Weiwen; Machalicek, Wendy – Journal of Autism and Developmental Disorders, 2020
This two-site randomized waitlist-control study (n = 96 mother-child dyads) examined the efficacy of a psychoeducation program as compared to usual care to empower Latina mothers and improve their confidence in and use of evidence-based practices (EBPs) for their children with ASD. A secondary aim was to improve child outcomes. Compared to control…

Gonthier, Corentin; Longuépée, Lucie; Bouvard, Martine – Journal of Autism and Developmental Disorders, 2016
Sensory processing abnormalities are relatively universal in individuals with autism spectrum disorder, and can be very disabling. Surprisingly, very few studies have investigated these abnormalities in low-functioning adults with autism. The goals of the present study were (a) to characterize distinct profiles of sensory dysfunction, and (b) to…

Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

Argumedes, Malena; Lanovaz, Marc J.; Larivée, Serge – Journal of Autism and Developmental Disorders, 2018
Challenging behaviors are a known predictor of high parenting stress in families of children with autism spectrum disorders. However, few studies have evaluated the effect of reducing challenging behaviors on parenting stress. The purpose of our study was to (a) examine the impact of reducing the frequency and severity of challenging behaviors on…
