Damien Wright; Aisling Kenny; Lindsay A. M. Mizen; Andrew G. McKechanie; Andrew C. Stanfield – American Journal on Intellectual and Developmental Disabilities, 2024
This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

Marie Antoinette Hodge; Rebecca Sutherland; Kelsie A. Boulton; Sarah Jane Baracz; Natalie Ong; Beverley Bennett; Adam J. Guastella; Natalie Silove – Autism: The International Journal of Research and Practice, 2025
Studies have shown that there are differences between the presentations of males and females diagnosed with autism. There remains a developing understanding about how the presentation of autism differs between boys (hereafter referred to as 'assigned males at birth') and girls (assigned females at birth). This study sought to investigate the…

Tschida, Jessica E.; Yerys, Benjamin E. – Autism: The International Journal of Research and Practice, 2022
Executive function challenges are commonly reported in the home setting for children with an autism spectrum disorder diagnosis (hereafter, autism), but little is known about these challenges in the school setting. A total of 337 youth (autism, N = 241 and typically developing, N = 96) were assessed using Behavior Rating Inventory of Executive…

McQuaid, Goldie A.; Pelphrey, Kevin A.; Bookheimer, Susan Y.; Dapretto, Mirella; Webb, Sara J.; Bernier, Raphael A.; McPartland, James C.; Van Horn, John D.; Wallace, Gregory L. – Autism: The International Journal of Research and Practice, 2021
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,…

Miller, Lauren E.; Dai, Yael G.; Fein, Deborah A.; Robins, Diana L. – Autism: The International Journal of Research and Practice, 2021
Autism spectrum disorder symptom emergence is heterogeneous, yet literature comparing young children diagnosed early versus later is relatively scant. Toddlers diagnosed with autism spectrum disorder between 12 and 18 months (n = 20), 19 and 24 months (n = 65), or 25 and 41 months (n = 27) were compared on demographics, developmental functioning,…

Rosen, Nicole E.; McCauley, James B.; Lord, Catherine – Autism: The International Journal of Research and Practice, 2022
Siblings play an important role in shaping the developmental trajectories of individuals with autism spectrum disorder. Having siblings has been associated with better social communication, non-verbal communication, and theory of mind abilities in autism spectrum disorder. However, little is known about the impact of siblings on adaptive skill…

Tomaszewski, Brianne; Hepburn, Susan; Blakeley-Smith, Audrey; Rogers, Sally J. – American Journal on Intellectual and Developmental Disabilities, 2020
Longitudinal growth modeling was utilized to examine adaptive behavior over eight years across the three time points (i.e., ages 2-10). Seventy-six parents completed the Vineland Adaptive Behavior Scales interviews of adaptive behavior. Child participants completed standardized developmental testing and an executive function task in toddlerhood…

McWhirter, Anna Cecilia; McIntyre, Laura Lee – Journal of Mental Health Research in Intellectual Disabilities, 2021
Introduction: Parenting children with intellectual and developmental disabilities can be stressful; however, families with religious beliefs may have positive ways of viewing their family. This study explored the associations between religious and spiritual involvement (RSI), family characteristics, parent mental health, and child adaptive and…

Northrup, Jessie B.; Goodwin, Matthew; Montrenes, Joshua; Vezzoli, Jessica; Golt, Josh; Peura, Christine B.; Siegel, Matthew; Mazefsky, Carla – Autism: The International Journal of Research and Practice, 2020
Emotional reactivity (e.g. explosive outbursts, tantrums) is a common but understudied challenge for individuals with autism spectrum disorder. Prior research has relied primarily on questionnaire data or observations of very young children. The current study coded emotional reactivity and recovery during a series of standardized frustration tasks…

Safer-Lichtenstein, Jonathan; McIntyre, Laura Lee – Focus on Autism and Other Developmental Disabilities, 2020
Rates of children identified as having autism spectrum disorder (ASD) continue to increase in both medical and school settings. While procedures for providing a medical diagnosis are relatively consistent throughout the United States, the process for determining special education eligibility under an ASD classification varies by state, with many…

Vivanti, Giacomo; Dissanayake, Cheryl; Duncan, Ed; Feary, Jessica; Capes, Kristy; Upson, Shannon; Bent, Catherine A.; Rogers, Sally J.; Hudry, Kristelle – Autism: The International Journal of Research and Practice, 2019
A major topic of debate is whether children with autism spectrum disorder should be educated in inclusive or specialized settings. We examined the feasibility and preliminary effectiveness of delivering the Group-Early Start Denver Model to children with autism spectrum disorder in inclusive versus specialized classrooms. We randomly assigned 44…

Alexander, Ryan M. – ProQuest LLC, 2017
Intelligence tests and adaptive behavior scales measure vital aspects of the multidimensional nature of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability, and both are frequently used conjointly in the assessment and identification of other developmental disabilities. The…

Frost, Kyle M.; Hong, Natalie; Lord, Catherine – American Journal on Intellectual and Developmental Disabilities, 2017
Individuals with autism spectrum disorder (ASD) tend to have significant delays in adaptive functioning. In this study, the relationship between adaptive behavior and ASD symptomatology was investigated in minimally verbal, school-aged children with ASD (n = 333). Both the social affect (SA) and restricted and repetitive behavior (RRB) domains…

Tomaszewski, Brianne; Smith DaWalt, Leann; Odom, Samuel L. – Autism: The International Journal of Research and Practice, 2019
This study examined growth trajectories of teacher-reported adaptive behavior in a diverse sample of adolescents with autism spectrum disorder. The participants were 244 adolescents between the ages of 14 and 21 years who were assessed at up to four time points across two and a half years of high school. Demographic variables (age, sex, race,…
